Background Insomnia is common amongst the elderly With the adverse effects of prolonged use of hypnotics the exploration ofnoninvasive and nonpharmacological complementary methods for insomnia is warranted Auriculotherapy (AT) is a therapeuticapproach where specific points on the auricle are stimulated to manage various physiological disorders The purpose of this studyis to determine the desirable treatment modality using AT to improve the sleep conditions of the elderly Methods A three-arm double-blinded randomised trial was conducted on 145 eligible subjects This study investigated three minimally invasiveprocedures namely laser auriculotherapy (LAT) magneto-auriculotherapy (MAT) and their combination Seven auricular pointswere used Treatment was performed three times a week for six weeks Subjects were assessed at baseline six weeks and follow-upafter six weeks three months and six months Generalised estimating equations were used to evaluate interactions amongst thegroups over time based on the Pittsburgh SleepQuality Index (PSQI) sleep parameters using actigraphicmonitoring health-relatedquality of life (HRQOL) using SF-12 and PHQ-9 for depression status Results The treatment effects of the three procedures werecomparable Significant improvements were found in all of the subjective measures (PSQI HRQOL and PHQ-9) for individualgroups over time Improvements in the objective sleep parameters using actigraphic monitoring were detected in subjects whoreceived MAT procedures but not in those who received LATThe combined MAT and LAT approach did not show any advantageoverMATConclusionsThe treatment effects of the three procedures were comparable in subjective parameters but not by objectivemeasures using actigraphicmonitoring Longer therapeutic course andmore frequent administration of LATmay be considered infuture trials to achieve the optimal treatment effectTrial Registration This trial is registeredwith ClinicalTrialsgov NCT02970695registered May 2016
1 Background
Insomnia is common amongst the elderly and in somecountries the reported prevalence rate is over 60 [1] Elderlypeople have difficulty falling asleep and maintaining sleepdue to frequent awakenings [1] Sleep loss in the agingpopulation is associated with depression anxiety increasedsuicidal risks comorbid chronic conditions and high fre-quency of accidents and falls [2ndash4] Moreover chronic sleepdisturbance can seriously compromise the overall quality oflife of those who suffer from it [5 6] Given the adverse effectsof prolonged use of hypnotics such as morning sedationimpaired balance drug dependence depression and amnesia
[1 7] the exploration of noninvasive and nonpharmaco-logical complementary methods for insomnia amongst theelderly is warranted
Auriculotherapy (AT) is a traditional Chinese medicine(TCM) approach in which the ear is viewed as a microsystemof the body [8] AT is a therapeutic method where specificpoints on the auricle are stimulated to treat various bodilydisorders Different materials such as acupuncture needlespress tack needles seeds magnetic pellets or low-energylaser could be applied on auricular points (denoted as ldquoacu-pointsrdquo in this paper) located on the external ear for therapeu-tic effect [8ndash11] However auricular acupuncture may inducepatientsrsquo discomfort and cause infection and inflammation

in the puncture sites Magneto-auriculotherapy (MAT) hasgradually emerged as a popular intervention for treatingmany chronic problems such as insomnia [12] low backpain [13] constipation [14] and hypertension [15] Theeffectiveness of magnetic pellets may be attributed to thefunctional changes caused by the interaction of magneticfields with biological tissues Such changes may be related tomoving ions in blood [16]
Laser auriculotherapy (LAT) has also been widely usedin different medical conditions including insomnia [17]pain relief [18] and weight reduction [19] The combinationof LAT and other treatments proposed in the literatureproduces a synergistic effect LAT has been combined withear point pressing to treat bed wetting in children [20] andwith auricular pressing therapy for alcoholic addiction [21]According to TCM the laser beam irradiates and stimulatesthe acupoint and activates the therapeutic effects of qi (energyflow) thereby regulating the functions of zang-fu (internalorgans) and restoring yin-yang (equilibrium) to produce atherapeutic effect [22]
Laser treatment is noninvasive painless and presentsno risk of infection or cross infection [22] As such thetherapeutic benefits of laser combined with MAT meritfurther investigation LAT followed by MAT optimises thetherapeutic effect because the latter allows continuous stim-ulation of acupoints after the laser treatment as long as themagnet pellets on the ears are in situ
In this study three minimally invasive proceduresnamely LAT MAT and their combination were investigatedto determine the desirable treatment modality using ATto improve the sleep conditions of the elderly Comparedwith the separate treatment procedures of MAT and LATtheir combined used is hypothesised to be more effective inimproving the sleep conditions and thereby the quality of lifeof the elderly with insomnia
2 Methods
21 Design This study employed a three-arm double-blindedrandomised trial Eligible subjects were randomly dividedinto three groups by using a computer-generated randomisedtable and the equal proportion rule (111)The randomcodingwas concealed from the subjects and evaluator by usingopaque envelopes
211 Settings and Participants Through convenience sam-pling subjects were recruited from elderly centres in HongKong A recruitment talk on AT was given to potentialsubjects in the targeted elderly centres The definition ofinsomnia is adapted from existing literature [23] After apreliminary screening volunteers aged 65 years or abovewere recruited if they have the following symptoms (1)difficulty falling or staying asleep andor frequent noctur-nal awakenings at least three nights per week (2) sleepdisturbance lasting for a minimum of 6 months and (3)poor quality of sleep as indicated by a PSQI score greaterthan five All the subjects fulfilled the criteria stipulated forthe diagnosis of insomnia in the lsquoDiagnostic and StatisticalManual of Mental Disordersrsquo fifth edition [24]The exclusion
criteria were as follows (1) presence of profound physicalillnesses such as stroke (2) diagnosis of obstructive sleepapnoea (3) wearing a hearing aid or pacemaker in situ(to prevent the magnetic pellets from interfering with thedevices) (4) received ATwithin the preceding sixmonths (5)suffering from aural injuries or infections and (6) inability tounderstand instructions or provide consent
22 Intervention and Procedures
221 Acupoints Selection Seven auricular points namelyldquoshenmenrdquo ldquoheartrdquo ldquoliverrdquo ldquospleenrdquo ldquokidneyrdquo ldquoocciputrdquoand ldquosubcortexrdquo (Figure 1) were selected because they pro-mote sleep as verified in a previous study by the first author[12] The selection was based on the nomenclature andlocation of acupoints published by the China StandardisationOrganising Committee (GBT 13734-2008) [25] Therapywas delivered by research personnel (SY) who had receivedintensive coaching from the first author (LS) Establishing theinterrater reliability and accuracy of the ear point identifica-tion scheme ensured the fidelity of the study
222 Groupings Group 1 (Placebo LAT and MAT) The laserdevice was switched to ldquopower offrdquo mode (ie deactivated)for acupoint lsquostimulationrsquo to achieve blinding and the placeboeffect before the MATThe subjects were asked to wear a pairof laser-protective goggles to lsquoblindrsquo them during treatmentMAT was then applied by placing magnetic pellets on theselected acupoints (Figure 2) Each magnetic pellet has anaverage gausspellet magnetic flux density of approximately200 Gs (20 mT) and a diameter of 176 mm
Group 2 (LAT and Placebo MAT) A laser device (PointerPulse) was used for LATThedevice has a wavelength of 650nm average output power of 25 mW energy density of 054Jcm2 for 1 minute and a pulse of 10Hz which is a commonlyacceptable dosage for clinical use [18 26] LAT used low-levellaser therapy (LLLT) in which the energy level emitted fromthe device is comparable with that of the teaching pointerThecontinuous mode of the device was used to directly treat theacupoints for one minute (Figure 3) A plaster centred with asmall dried stem of Junci medulla a soft perennial plant wasprovided to mimic MAT In a previous study J medulla wassuccessfully adopted as a placebo because it did not induceany physical pressure on the acupoints of the ear [12]
Group 3 (Combined AT) The subjects received the com-bined LAT and MAT The procedures for applying LAT andMAT were identical to the abovementioned descriptions
223 Procedures Therapies were administered at elderlycentres adjacent to the subjectsrsquo residences The followingprocedures were standardised across the three groups toenhance the blinding effect All therapies were administeredin a room assigned for research purposes Laser-protectivegoggles specific for the wavelengths of the laser device wereprovided to the subjects and researchers for eye protection
The auricle of every subject was cleaned with 75 iso-propyl alcohol before therapy Only one ear was treated at atimeThe treatment was applied alternately to the right ear inthe first visit and then to the left ear in the subsequent visit

We replaced the experimental objects (ie magnetic pelletsfor true MAT or J medulla for placebo MAT) every otherday that is three times a week (except Sunday) to preventlocal irritation of acupoints The total treatment period wassix weeks
Participation in the study was voluntary Writteninformed consent was obtained from each subject uponexplaining the risks and benefits of their participationEthical approval was obtained from the Human ResearchEthics Review Committee of the Hong Kong PolytechnicUniversity The study was conducted in accordance with theDeclaration of Helsinki Given their multiple visits to thecentres to receive treatment the subjects were provided atravel subsidy in the form of supermarket coupons uponcompletion of the study
224 Treatment Effect Evaluation Thesubjectswere assessedat baseline at six weeks (postintervention) and duringfollow-up after six weeks three months and six months Toachieve evaluator blinding the assessment was conductedby a different researcher who was unaware of the treatmentmodality given to the subjects PSQI which was used tocollect data related to the sleep conditions of the subjectswas considered as the primary outcomeThis instrument wasscored from 0 to 21 and scores greater than five indicatedpoor sleep quality Chong andCheung [27] validated theCan-tonese PSQI and reported a high internal consistency of 075
The secondary outcomes considered are as follows(1) actigraphic monitoring was conducted to collect sleepparameters including sleep latency (minutes) waking aftersleep onset (minutes) total sleep time (hours) and sleep

efficiency () An Actiwatchrsquo Spectrum Plus device with0025G ultra-high sensitivity and 32 Hz sampling rate wasused in actigraphic monitoring The subjects were requestedto wear the device on the wrist of their nondominant hand 24hours a day for 7 consecutive days to determine the overallsleep conditions within a certain period Data were collectedin epochs every 30 second These epoch-by-epoch data werestored in the internal memory of the device until theycould be downloaded to a computer Actiware 6 ActigraphAnalysis Software was used for sleep analysis (2)TheChinese(HK) SF-12 v2copy an abbreviated version of the SF36 healthquestionnaire was used to evaluate the health-related qualityof life (HRQOL) of the subjects This instrument covered 12items and the resultswere presented by a physical componentscore (PCS) and a mental component score (MCS) PCS andMCS ranged from 0 to 100 with higher scores indicatingbetter HRQOL [28] (3) Patient Health Questionnaire (PHQ-9) was also used This instrument was validated as a usefultool for assessing depression status The scores ranged from0 to 27 and high scores indicated severe depression status[29] The scale had a Cronbachrsquos alpha of 082 and therecommended cut-off score was 8 [30]
The subjectsrsquo expectations and satisfaction towards thetherapy were evaluated using a 10-point scale with highscores indicating high expectations or satisfaction [31] Datawere likewise collected on sociodemographic characteris-tics including age gender marital status educational levelreligion number of family members body mass indexsingleshared bed comorbid illnesses use of sleeping pillsor aids and current medications taken Similarly monitoredwere the recruitment rate compliance rate of the treatmentprotocol and adverse effects arising from the therapy
225 Data Analyses Descriptive statistics were determinedon the sociodemographic and clinical characteristics of the
subjects The estimated mean and standard error were com-puted for the outcome variables of each time point Associa-tion amongst categorical variables was estimated using x2 testor Fisherrsquos exact test where appropriate to identify significantvariables for inclusion in the generalised estimating equa-tions (GEE) for adjustment One-way analysis of variancewas used to examine group differences Primary analysiswas conducted using GEE model with an autoregressioncorrelation structure to evaluate interactions amongst thegroups over time (baseline to six months follow-up) on theprimary outcome (ie PSQI score) and secondary outcomes(sleep parameters using 24-hour actigraphic monitoringquality of life using SF-12 and PHQ-9) Missing data werehandled usingGEE and assumed to be random [32]Themainanalysis was repeated at postintervention and during thefollow-up sessions (up to six months) for sensitivity analysisSPSS version 250 (IBM Corporation USA) was used for allstatistical analyses All statistical tests were two sided withsignificance level set at 005
3 Results
The study was conducted from May 2016 to May 2018Data were collected from 11 centres for the elderly and therecruitment rate was 886 A total of 147 eligible subjectswere randomly divided into three groups (Group 1=50Group2=46 and Group 3=51)
31 Participantsrsquo Characteristics The recruited subjects hadan average age of 7529 yearsplusmn 699 with a mean durationof insomnia for 1012 plusmn 1067 years Majority of the subjects(700) did not take any medication to manage their sleepproblems The groups were essentially comparable and wellbalanced in terms of sociodemographic variables includ-ing gender distribution body mass index education level

marital status comorbid illnesses and regular medicationstaken However age showed slight significant differencesamongst the groups and thus this variable was adjusted inthe GEE models in subsequent analyses According to the24-hour actigraphic recordings the subjects had an averageof poor sleep quality (PSQI 1263 plusmn324 sleep efficiency7233 plusmn1609) long sleep latency (2703 plusmn 2313 minutes)short total sleep time (376 plusmn 196 hours) and waking aftersleep onset (9031plusmn 8853minutes)The subjects also hadmilddepression (PHQ-9 947 plusmn 607) and low HRQOL in termsof physical component (4139 plusmn 851) and mental component(4668 plusmn 1234) (Table 1)
32 Compliance Expectation and Satisfaction towards theTreatment Compliance with the intervention protocol washigh at an average of 952 (n = 140) of the subjects contin-ued with postintervention and all follow-up measurementsuntil six months The recruitment flowchart is illustrated inFigure 4 Althoughmajority of the subjects (653) had nevertried complementary and alternative treatments they gener-ally exhibited strong confidence in the proposed therapy (782of 10) and had a relatively high expectation of its effectiveness(773 of 10) before the trial After the intervention the subjectsin Group 1 had the highest satisfaction from the therapy(786) followed by those in Group 3 (758) and Group 2 (702)A correlation analysis was conducted between expectationsof the treatment effect and sleep parameters (PSQI SE)However no significant relationship was detected (pgt005)Over 75 of the subjects (n = 109) indicated that they woulddefinitely recommend the therapy to others No specificadverse effects were observed arising from the therapyapart from 16 cases (109) who reported having mild skinirritation on the ears due to the adhesive tapes that were usedto hold the experimental tools in place and 20 cases (136)who felt tenderness on the acupoints (most of these subjectsreceived MAT) The number of subjects who believed thatthey might be receiving placebo treatment was higher inGroup 1 than in the other groups although majority of thesubjects (90) believed that they were not receiving placebo(Table 2)
33 Treatment Effect The differences in the primary andsecondary outcomes of the three groups across differenttime points were compared through GEE model analysiswith adjustment for age In general no significant differ-ences were detected in the outcomes (including PSQI sleepparameters measured by actigraphic monitoring SF-12 andPHQ-9) of the three groups (Table 3) However significantdifferences were found in all of the subjective measuresincluding PSQI (Figure 5) SF-12 (physical andor mentalcomponents) (Figures S1 and S2) and PHQ-9 (Figure 6) forindividual groups over time When the sleep conditions wereevaluated by actigraphic monitoring significant differencesin lsquowaking after sleep onsetrsquo (minutes) (Figure S3) and lsquosleepefficiencyrsquo () (Figure S4) were detected only in Groups 1and 3 (Table 4) The completersrsquo analysis showed consistentfindings on the primary and secondary outcomes of thetrial
4 Discussion
Numerous studies that used AT to manage sleep problemsin China encountered methodological flaws which renderedtheir findings unconvincingThe commonproblems includedlack of details on how randomisation and allocation conceal-ment were conducted absence of objective measurementsand a control or placebo group as well as failure to report theuse of blinding and selective reporting of findings [33ndash35]The present study was performed using a scientific approachto identify the optimum treatment protocol forAT in improv-ing the sleep conditions and quality of life of the elderlywith insomnia This meticulous randomised controlled trial(RCT) could provide scientific evidence regarding causalrelationships between interventions and outcomes
In general the treatment effect was comparable amongstthe three AT protocols However significant improvementswere observed in all of the subjective measures includingsleep conditions measured by PSQI HRQOL and depressionstatus for individual groups over time When the sleepconditions were evaluated by objective measures using acti-graphic monitoring significant differences in ldquowaking aftersleep onsetrdquo (minutes) and ldquosleep efficiencyrdquo () were onlynoted in Groups 1 and 3 The use of actigraphs has beenwidely recognised as an objective measurement that couldprovide longitudinal assessment of sleep patterns in a naturalenvironment [36 37]This technique could similarly providevalidmeasures thatmay not be influenced by subject bias Sig-nificant reduction in the awakening time after sleep onset andincrease in sleep efficiency were only detected in subjects whoreceived MAT protocols (ie Groups 1 and 3) but not in thosewho received only the LAT protocol Despite the improvedsleep efficiency of the subjects at postintervention and duringthe follow-up periods the evaluated indices remained below85 a common cut-off percentage that indicates the presenceof sleep disturbances [38] Sleep efficiency is calculated bydividing the total sleep time by total bedtime a higher sleepefficiency means better sleep quantity and quality A longtherapeutic course such as 10ndash12 weeks may be necessaryto further elevate sleep efficiency to a desirable level throughsustainable treatment effect
MAT could provide continuous stimulation of acupointsas long as the magnetic pellets on the ears are in situ and thesubjects could receive laser stimulation to the acupoints onthe day of treatment The synergistic effect of the combinedMAT and LAT was demonstrated in two previous trials[39 40] conducted by the research team In a double-blindRCT for osteoarthritic knee the subjects who received thecombined AT protocols exhibited stronger treatment effectsin terms of pain relief ambulation status and range of kneemovements compared with those treated with separate MATor LAT [39] whereas in another double-blinded RCT foraging males with lower urinary tract symptoms a combinedAT protocol exhibited a stronger therapeutic effect in reliev-ing voiding problems improving the urinary flow rate andminimizing the postvoid residual urine than the placebogroup or MAT alone [40] However the combined MAT andLAT approach did not show any advantage over the separateMAT protocol in current studyTherefore a greater frequency

for LAT administration such as daily application adoptedin previous studies [41ndash44] may be considered in futurestudies to enhance the treatment effect and possibly improveits synergistic effect when combined with MAT
Numerous clinical trials reported the use of MAT ondifferent disorders including but not limited to sleep dis-turbances [12 45 46] low back pain [13] constipation [14]and obesity [47] The effectiveness of MAT may relate to the
interaction of magnetic fields with blood flow and calciumchannel proteins in the cell membrane Such interactionsmay elicit functional body changes [16 48 49] MeanwhileLAT is a noninvasive alternative to needle acupuncture [22]and has been adopted to increase pain threshold [50] aswell as relieve musculoskeletal pain [18] and insomnia [17]The laser beam not only irradiates and stimulates acupointsbut also triggers the energy flow (qi) and regulates the

functions of internal organs to achieve a therapeutic effect[22]
According to neuroembryonic theory Dr Paul Nogierviewed the auricle as a homunculus of the human bodyand has a similar shape to an inverted foetus [8] As suchappropriate stimulation of specific ear acupoints can achievetherapeutic effects [51] In the present study the selection ofauricular acupoints was based on the TCM theory and ideasborrowed from modern medicine For example treating the
ldquoheartrdquo can calm the mind while soothing the ldquoliverrdquo couldregulate the flow of qi particularly when insomnia is causedby liver qi stagnation [52] ldquoShenmenrdquo and ldquoocciputrdquo arebelieved to tranquilise the mind and the lsquosubcortexrsquo canharmonise cortex excitement and inhibition [12]
A population-based epidemiological study conducted on5000 subjects in Hong Kong reported that insomnia washighly prevalent amongst Chinese adults and was associatedwith poor mental status and quality of life [53] The present
Evidence-Based Complementary and Alternative Medicine 17
study reported PCS scores of the subjects comparable withthose of Hong Kong people with insomnia (4321 in ourstudy versus 4139 population norm) but stated a slightlyhigherMCS (4668 versus 3636)HRQOL (in PCS andMCS)improved and depression declined over time in subjectstreated with AT Thus quality of life and emotional statusof the subjects may be positively associated with sleepimprovement after the therapy
No specific adverse effectswere observed to arise from thetherapy apart from a small number of reported cases (109)having mild skin irritation on the ears from the adhesivetapes used to hold the experimental tools in place Moreover20 cases (136) reported tenderness on the acupoints andmost of these subjects received MAT According to theauricular diagnosis system the areas of the auricle withheightened tenderness upon touching correspond to specificareas of the body where pathological conditions exist [5455] Applying magnetic pellets may induce physical pressureon the ear acupoints and cause tenderness especially incases with disequilibrium of bodily functions (eg insomnia)corresponding to specific acupoints The tenderness on thereflective acupoints experienced by the subjects may beconsidered part of the treatment process rather than adverseeffects of AT
The high compliance rate (952) and positive impres-sion of the therapy indirectly indicated that blinding wassuccessful because of the successful placebo applicationin the trial Over 75 of the participants expressed thatthey would definitely recommend the therapy to othersThe findings of this trial can provide valuable informationand increase understanding of the therapeutic effect of ATwhether separate or combinedMATandLAT Longer therapyduration may be considered in future trials to determinefurther improvements in the outcome variables The pro-posed treatment approach can be considered as a noninvasivestrategy for managing insomnia amongst the elderly
Although actigraphic monitoring is a reliable objectivemeasure in sleep study changes in different sleep stagescaused by the therapy cannot be ascertained The recruitedelders generally obtained low education levels and had amean age of over 75 and therefore using a sleep log toverify the actigraphic data was not feasible Night-to-nightvariability in the sleeping patterns of subjects may also beaffected by physical psychological andor environmentalfactors Due to the above limitations the actigraphic datamust be interpreted with caution The exact mechanismsremain unknown regarding the interaction of magnetic fieldswith biological tissues which results in functional changesFurther studies from the biomedical perspective are requiredto elucidate the biological pathway of the treatment and effectsuch as to examine the impact of the treatment protocolson the changes in sleep biomarkers when sleep prosperity isachieved
5 Implications
This study provides valuable findings regarding the therapeu-tic effect of different protocols usingMAT LAT or their com-bination In general the AT protocols under testing may be
considered as a noninvasive approach with minimal adverseeffects for managing sleep problems amongst the elderlyThe findings of this study provide important implications toguide future research and apply evidence-based practice inthe community via service provision tomanage this commonproblem
6 Conclusion
The treatment effects of the three protocols were comparablein terms of self-reported sleep conditions HRQOL anddepression status In several parameters such therapeuticeffects may be sustained at six-month follow-up Significantimprovement in the objective sleep parameters could beobserved in subjects who received MAT protocols but notin those who received LAT The combined MAT and LATapproach did not show any advantage over MAT Longertherapeutic course and more frequent administration of LATmay be considered in future trials to achieve the optimaltreatment effect In general the proposed AT protocolswere demonstrated to be a well-received treatment modalitywith minimal adverse effects and effectively improved sleepconditions of the elderly with insomnia

2 Evidence-Based Complementary and Alternative Medicine
in the puncture sites Magneto-auriculotherapy (MAT) hasgradually emerged as a popular intervention for treatingmany chronic problems such as insomnia [12] low backpain [13] constipation [14] and hypertension [15] Theeffectiveness of magnetic pellets may be attributed to thefunctional changes caused by the interaction of magneticfields with biological tissues Such changes may be related tomoving ions in blood [16]
Laser auriculotherapy (LAT) has also been widely usedin different medical conditions including insomnia [17]pain relief [18] and weight reduction [19] The combinationof LAT and other treatments proposed in the literatureproduces a synergistic effect LAT has been combined withear point pressing to treat bed wetting in children [20] andwith auricular pressing therapy for alcoholic addiction [21]According to TCM the laser beam irradiates and stimulatesthe acupoint and activates the therapeutic effects of qi (energyflow) thereby regulating the functions of zang-fu (internalorgans) and restoring yin-yang (equilibrium) to produce atherapeutic effect [22]
Laser treatment is noninvasive painless and presentsno risk of infection or cross infection [22] As such thetherapeutic benefits of laser combined with MAT meritfurther investigation LAT followed by MAT optimises thetherapeutic effect because the latter allows continuous stim-ulation of acupoints after the laser treatment as long as themagnet pellets on the ears are in situ
In this study three minimally invasive proceduresnamely LAT MAT and their combination were investigatedto determine the desirable treatment modality using ATto improve the sleep conditions of the elderly Comparedwith the separate treatment procedures of MAT and LATtheir combined used is hypothesised to be more effective inimproving the sleep conditions and thereby the quality of lifeof the elderly with insomnia
2 Methods
21 Design This study employed a three-arm double-blindedrandomised trial Eligible subjects were randomly dividedinto three groups by using a computer-generated randomisedtable and the equal proportion rule (111)The randomcodingwas concealed from the subjects and evaluator by usingopaque envelopes
211 Settings and Participants Through convenience sam-pling subjects were recruited from elderly centres in HongKong A recruitment talk on AT was given to potentialsubjects in the targeted elderly centres The definition ofinsomnia is adapted from existing literature [23] After apreliminary screening volunteers aged 65 years or abovewere recruited if they have the following symptoms (1)difficulty falling or staying asleep andor frequent noctur-nal awakenings at least three nights per week (2) sleepdisturbance lasting for a minimum of 6 months and (3)poor quality of sleep as indicated by a PSQI score greaterthan five All the subjects fulfilled the criteria stipulated forthe diagnosis of insomnia in the lsquoDiagnostic and StatisticalManual of Mental Disordersrsquo fifth edition [24]The exclusion
criteria were as follows (1) presence of profound physicalillnesses such as stroke (2) diagnosis of obstructive sleepapnoea (3) wearing a hearing aid or pacemaker in situ(to prevent the magnetic pellets from interfering with thedevices) (4) received ATwithin the preceding sixmonths (5)suffering from aural injuries or infections and (6) inability tounderstand instructions or provide consent
22 Intervention and Procedures
221 Acupoints Selection Seven auricular points namelyldquoshenmenrdquo ldquoheartrdquo ldquoliverrdquo ldquospleenrdquo ldquokidneyrdquo ldquoocciputrdquoand ldquosubcortexrdquo (Figure 1) were selected because they pro-mote sleep as verified in a previous study by the first author[12] The selection was based on the nomenclature andlocation of acupoints published by the China StandardisationOrganising Committee (GBT 13734-2008) [25] Therapywas delivered by research personnel (SY) who had receivedintensive coaching from the first author (LS) Establishing theinterrater reliability and accuracy of the ear point identifica-tion scheme ensured the fidelity of the study
222 Groupings Group 1 (Placebo LAT and MAT) The laserdevice was switched to ldquopower offrdquo mode (ie deactivated)for acupoint lsquostimulationrsquo to achieve blinding and the placeboeffect before the MATThe subjects were asked to wear a pairof laser-protective goggles to lsquoblindrsquo them during treatmentMAT was then applied by placing magnetic pellets on theselected acupoints (Figure 2) Each magnetic pellet has anaverage gausspellet magnetic flux density of approximately200 Gs (20 mT) and a diameter of 176 mm
Group 2 (LAT and Placebo MAT) A laser device (PointerPulse) was used for LATThedevice has a wavelength of 650nm average output power of 25 mW energy density of 054Jcm2 for 1 minute and a pulse of 10Hz which is a commonlyacceptable dosage for clinical use [18 26] LAT used low-levellaser therapy (LLLT) in which the energy level emitted fromthe device is comparable with that of the teaching pointerThecontinuous mode of the device was used to directly treat theacupoints for one minute (Figure 3) A plaster centred with asmall dried stem of Junci medulla a soft perennial plant wasprovided to mimic MAT In a previous study J medulla wassuccessfully adopted as a placebo because it did not induceany physical pressure on the acupoints of the ear [12]
Group 3 (Combined AT) The subjects received the com-bined LAT and MAT The procedures for applying LAT andMAT were identical to the abovementioned descriptions
223 Procedures Therapies were administered at elderlycentres adjacent to the subjectsrsquo residences The followingprocedures were standardised across the three groups toenhance the blinding effect All therapies were administeredin a room assigned for research purposes Laser-protectivegoggles specific for the wavelengths of the laser device wereprovided to the subjects and researchers for eye protection
The auricle of every subject was cleaned with 75 iso-propyl alcohol before therapy Only one ear was treated at atimeThe treatment was applied alternately to the right ear inthe first visit and then to the left ear in the subsequent visit

We replaced the experimental objects (ie magnetic pelletsfor true MAT or J medulla for placebo MAT) every otherday that is three times a week (except Sunday) to preventlocal irritation of acupoints The total treatment period wassix weeks
Participation in the study was voluntary Writteninformed consent was obtained from each subject uponexplaining the risks and benefits of their participationEthical approval was obtained from the Human ResearchEthics Review Committee of the Hong Kong PolytechnicUniversity The study was conducted in accordance with theDeclaration of Helsinki Given their multiple visits to thecentres to receive treatment the subjects were provided atravel subsidy in the form of supermarket coupons uponcompletion of the study
224 Treatment Effect Evaluation Thesubjectswere assessedat baseline at six weeks (postintervention) and duringfollow-up after six weeks three months and six months Toachieve evaluator blinding the assessment was conductedby a different researcher who was unaware of the treatmentmodality given to the subjects PSQI which was used tocollect data related to the sleep conditions of the subjectswas considered as the primary outcomeThis instrument wasscored from 0 to 21 and scores greater than five indicatedpoor sleep quality Chong andCheung [27] validated theCan-tonese PSQI and reported a high internal consistency of 075
The secondary outcomes considered are as follows(1) actigraphic monitoring was conducted to collect sleepparameters including sleep latency (minutes) waking aftersleep onset (minutes) total sleep time (hours) and sleep

The subjectsrsquo expectations and satisfaction towards thetherapy were evaluated using a 10-point scale with highscores indicating high expectations or satisfaction [31] Datawere likewise collected on sociodemographic characteris-tics including age gender marital status educational levelreligion number of family members body mass indexsingleshared bed comorbid illnesses use of sleeping pillsor aids and current medications taken Similarly monitoredwere the recruitment rate compliance rate of the treatmentprotocol and adverse effects arising from the therapy
225 Data Analyses Descriptive statistics were determinedon the sociodemographic and clinical characteristics of the
subjects The estimated mean and standard error were com-puted for the outcome variables of each time point Associa-tion amongst categorical variables was estimated using x2 testor Fisherrsquos exact test where appropriate to identify significantvariables for inclusion in the generalised estimating equa-tions (GEE) for adjustment One-way analysis of variancewas used to examine group differences Primary analysiswas conducted using GEE model with an autoregressioncorrelation structure to evaluate interactions amongst thegroups over time (baseline to six months follow-up) on theprimary outcome (ie PSQI score) and secondary outcomes(sleep parameters using 24-hour actigraphic monitoringquality of life using SF-12 and PHQ-9) Missing data werehandled usingGEE and assumed to be random [32]Themainanalysis was repeated at postintervention and during thefollow-up sessions (up to six months) for sensitivity analysisSPSS version 250 (IBM Corporation USA) was used for allstatistical analyses All statistical tests were two sided withsignificance level set at 005

32 Compliance Expectation and Satisfaction towards theTreatment Compliance with the intervention protocol washigh at an average of 952 (n = 140) of the subjects contin-ued with postintervention and all follow-up measurementsuntil six months The recruitment flowchart is illustrated inFigure 4 Althoughmajority of the subjects (653) had nevertried complementary and alternative treatments they gener-ally exhibited strong confidence in the proposed therapy (782of 10) and had a relatively high expectation of its effectiveness(773 of 10) before the trial After the intervention the subjectsin Group 1 had the highest satisfaction from the therapy(786) followed by those in Group 3 (758) and Group 2 (702)A correlation analysis was conducted between expectationsof the treatment effect and sleep parameters (PSQI SE)However no significant relationship was detected (pgt005)Over 75 of the subjects (n = 109) indicated that they woulddefinitely recommend the therapy to others No specificadverse effects were observed arising from the therapyapart from 16 cases (109) who reported having mild skinirritation on the ears due to the adhesive tapes that were usedto hold the experimental tools in place and 20 cases (136)who felt tenderness on the acupoints (most of these subjectsreceived MAT) The number of subjects who believed thatthey might be receiving placebo treatment was higher inGroup 1 than in the other groups although majority of thesubjects (90) believed that they were not receiving placebo(Table 2)
33 Treatment Effect The differences in the primary andsecondary outcomes of the three groups across differenttime points were compared through GEE model analysiswith adjustment for age In general no significant differ-ences were detected in the outcomes (including PSQI sleepparameters measured by actigraphic monitoring SF-12 andPHQ-9) of the three groups (Table 3) However significantdifferences were found in all of the subjective measuresincluding PSQI (Figure 5) SF-12 (physical andor mentalcomponents) (Figures S1 and S2) and PHQ-9 (Figure 6) forindividual groups over time When the sleep conditions wereevaluated by actigraphic monitoring significant differencesin lsquowaking after sleep onsetrsquo (minutes) (Figure S3) and lsquosleepefficiencyrsquo () (Figure S4) were detected only in Groups 1and 3 (Table 4) The completersrsquo analysis showed consistentfindings on the primary and secondary outcomes of thetrial
4 Discussion
Numerous studies that used AT to manage sleep problemsin China encountered methodological flaws which renderedtheir findings unconvincingThe commonproblems includedlack of details on how randomisation and allocation conceal-ment were conducted absence of objective measurementsand a control or placebo group as well as failure to report theuse of blinding and selective reporting of findings [33ndash35]The present study was performed using a scientific approachto identify the optimum treatment protocol forAT in improv-ing the sleep conditions and quality of life of the elderlywith insomnia This meticulous randomised controlled trial(RCT) could provide scientific evidence regarding causalrelationships between interventions and outcomes
In general the treatment effect was comparable amongstthe three AT protocols However significant improvementswere observed in all of the subjective measures includingsleep conditions measured by PSQI HRQOL and depressionstatus for individual groups over time When the sleepconditions were evaluated by objective measures using acti-graphic monitoring significant differences in ldquowaking aftersleep onsetrdquo (minutes) and ldquosleep efficiencyrdquo () were onlynoted in Groups 1 and 3 The use of actigraphs has beenwidely recognised as an objective measurement that couldprovide longitudinal assessment of sleep patterns in a naturalenvironment [36 37]This technique could similarly providevalidmeasures thatmay not be influenced by subject bias Sig-nificant reduction in the awakening time after sleep onset andincrease in sleep efficiency were only detected in subjects whoreceived MAT protocols (ie Groups 1 and 3) but not in thosewho received only the LAT protocol Despite the improvedsleep efficiency of the subjects at postintervention and duringthe follow-up periods the evaluated indices remained below85 a common cut-off percentage that indicates the presenceof sleep disturbances [38] Sleep efficiency is calculated bydividing the total sleep time by total bedtime a higher sleepefficiency means better sleep quantity and quality A longtherapeutic course such as 10ndash12 weeks may be necessaryto further elevate sleep efficiency to a desirable level throughsustainable treatment effect
MAT could provide continuous stimulation of acupointsas long as the magnetic pellets on the ears are in situ and thesubjects could receive laser stimulation to the acupoints onthe day of treatment The synergistic effect of the combinedMAT and LAT was demonstrated in two previous trials[39 40] conducted by the research team In a double-blindRCT for osteoarthritic knee the subjects who received thecombined AT protocols exhibited stronger treatment effectsin terms of pain relief ambulation status and range of kneemovements compared with those treated with separate MATor LAT [39] whereas in another double-blinded RCT foraging males with lower urinary tract symptoms a combinedAT protocol exhibited a stronger therapeutic effect in reliev-ing voiding problems improving the urinary flow rate andminimizing the postvoid residual urine than the placebogroup or MAT alone [40] However the combined MAT andLAT approach did not show any advantage over the separateMAT protocol in current studyTherefore a greater frequency

for LAT administration such as daily application adoptedin previous studies [41ndash44] may be considered in futurestudies to enhance the treatment effect and possibly improveits synergistic effect when combined with MAT
Numerous clinical trials reported the use of MAT ondifferent disorders including but not limited to sleep dis-turbances [12 45 46] low back pain [13] constipation [14]and obesity [47] The effectiveness of MAT may relate to the
interaction of magnetic fields with blood flow and calciumchannel proteins in the cell membrane Such interactionsmay elicit functional body changes [16 48 49] MeanwhileLAT is a noninvasive alternative to needle acupuncture [22]and has been adopted to increase pain threshold [50] aswell as relieve musculoskeletal pain [18] and insomnia [17]The laser beam not only irradiates and stimulates acupointsbut also triggers the energy flow (qi) and regulates the

functions of internal organs to achieve a therapeutic effect[22]
According to neuroembryonic theory Dr Paul Nogierviewed the auricle as a homunculus of the human bodyand has a similar shape to an inverted foetus [8] As suchappropriate stimulation of specific ear acupoints can achievetherapeutic effects [51] In the present study the selection ofauricular acupoints was based on the TCM theory and ideasborrowed from modern medicine For example treating the
ldquoheartrdquo can calm the mind while soothing the ldquoliverrdquo couldregulate the flow of qi particularly when insomnia is causedby liver qi stagnation [52] ldquoShenmenrdquo and ldquoocciputrdquo arebelieved to tranquilise the mind and the lsquosubcortexrsquo canharmonise cortex excitement and inhibition [12]
A population-based epidemiological study conducted on5000 subjects in Hong Kong reported that insomnia washighly prevalent amongst Chinese adults and was associatedwith poor mental status and quality of life [53] The present
Evidence-Based Complementary and Alternative Medicine 17
study reported PCS scores of the subjects comparable withthose of Hong Kong people with insomnia (4321 in ourstudy versus 4139 population norm) but stated a slightlyhigherMCS (4668 versus 3636)HRQOL (in PCS andMCS)improved and depression declined over time in subjectstreated with AT Thus quality of life and emotional statusof the subjects may be positively associated with sleepimprovement after the therapy
No specific adverse effectswere observed to arise from thetherapy apart from a small number of reported cases (109)having mild skin irritation on the ears from the adhesivetapes used to hold the experimental tools in place Moreover20 cases (136) reported tenderness on the acupoints andmost of these subjects received MAT According to theauricular diagnosis system the areas of the auricle withheightened tenderness upon touching correspond to specificareas of the body where pathological conditions exist [5455] Applying magnetic pellets may induce physical pressureon the ear acupoints and cause tenderness especially incases with disequilibrium of bodily functions (eg insomnia)corresponding to specific acupoints The tenderness on thereflective acupoints experienced by the subjects may beconsidered part of the treatment process rather than adverseeffects of AT
The high compliance rate (952) and positive impres-sion of the therapy indirectly indicated that blinding wassuccessful because of the successful placebo applicationin the trial Over 75 of the participants expressed thatthey would definitely recommend the therapy to othersThe findings of this trial can provide valuable informationand increase understanding of the therapeutic effect of ATwhether separate or combinedMATandLAT Longer therapyduration may be considered in future trials to determinefurther improvements in the outcome variables The pro-posed treatment approach can be considered as a noninvasivestrategy for managing insomnia amongst the elderly
Although actigraphic monitoring is a reliable objectivemeasure in sleep study changes in different sleep stagescaused by the therapy cannot be ascertained The recruitedelders generally obtained low education levels and had amean age of over 75 and therefore using a sleep log toverify the actigraphic data was not feasible Night-to-nightvariability in the sleeping patterns of subjects may also beaffected by physical psychological andor environmentalfactors Due to the above limitations the actigraphic datamust be interpreted with caution The exact mechanismsremain unknown regarding the interaction of magnetic fieldswith biological tissues which results in functional changesFurther studies from the biomedical perspective are requiredto elucidate the biological pathway of the treatment and effectsuch as to examine the impact of the treatment protocolson the changes in sleep biomarkers when sleep prosperity isachieved
5 Implications
This study provides valuable findings regarding the therapeu-tic effect of different protocols usingMAT LAT or their com-bination In general the AT protocols under testing may be
considered as a noninvasive approach with minimal adverseeffects for managing sleep problems amongst the elderlyThe findings of this study provide important implications toguide future research and apply evidence-based practice inthe community via service provision tomanage this commonproblem
6 Conclusion
The treatment effects of the three protocols were comparablein terms of self-reported sleep conditions HRQOL anddepression status In several parameters such therapeuticeffects may be sustained at six-month follow-up Significantimprovement in the objective sleep parameters could beobserved in subjects who received MAT protocols but notin those who received LAT The combined MAT and LATapproach did not show any advantage over MAT Longertherapeutic course and more frequent administration of LATmay be considered in future trials to achieve the optimaltreatment effect In general the proposed AT protocolswere demonstrated to be a well-received treatment modalitywith minimal adverse effects and effectively improved sleepconditions of the elderly with insomnia

We replaced the experimental objects (ie magnetic pelletsfor true MAT or J medulla for placebo MAT) every otherday that is three times a week (except Sunday) to preventlocal irritation of acupoints The total treatment period wassix weeks
Participation in the study was voluntary Writteninformed consent was obtained from each subject uponexplaining the risks and benefits of their participationEthical approval was obtained from the Human ResearchEthics Review Committee of the Hong Kong PolytechnicUniversity The study was conducted in accordance with theDeclaration of Helsinki Given their multiple visits to thecentres to receive treatment the subjects were provided atravel subsidy in the form of supermarket coupons uponcompletion of the study
224 Treatment Effect Evaluation Thesubjectswere assessedat baseline at six weeks (postintervention) and duringfollow-up after six weeks three months and six months Toachieve evaluator blinding the assessment was conductedby a different researcher who was unaware of the treatmentmodality given to the subjects PSQI which was used tocollect data related to the sleep conditions of the subjectswas considered as the primary outcomeThis instrument wasscored from 0 to 21 and scores greater than five indicatedpoor sleep quality Chong andCheung [27] validated theCan-tonese PSQI and reported a high internal consistency of 075
The secondary outcomes considered are as follows(1) actigraphic monitoring was conducted to collect sleepparameters including sleep latency (minutes) waking aftersleep onset (minutes) total sleep time (hours) and sleep

efficiency () An Actiwatchrsquo Spectrum Plus device with0025G ultra-high sensitivity and 32 Hz sampling rate wasused in actigraphic monitoring The subjects were requestedto wear the device on the wrist of their nondominant hand 24hours a day for 7 consecutive days to determine the overallsleep conditions within a certain period Data were collectedin epochs every 30 second These epoch-by-epoch data werestored in the internal memory of the device until theycould be downloaded to a computer Actiware 6 ActigraphAnalysis Software was used for sleep analysis (2)TheChinese(HK) SF-12 v2copy an abbreviated version of the SF36 healthquestionnaire was used to evaluate the health-related qualityof life (HRQOL) of the subjects This instrument covered 12items and the resultswere presented by a physical componentscore (PCS) and a mental component score (MCS) PCS andMCS ranged from 0 to 100 with higher scores indicatingbetter HRQOL [28] (3) Patient Health Questionnaire (PHQ-9) was also used This instrument was validated as a usefultool for assessing depression status The scores ranged from0 to 27 and high scores indicated severe depression status[29] The scale had a Cronbachrsquos alpha of 082 and therecommended cut-off score was 8 [30]
The subjectsrsquo expectations and satisfaction towards thetherapy were evaluated using a 10-point scale with highscores indicating high expectations or satisfaction [31] Datawere likewise collected on sociodemographic characteris-tics including age gender marital status educational levelreligion number of family members body mass indexsingleshared bed comorbid illnesses use of sleeping pillsor aids and current medications taken Similarly monitoredwere the recruitment rate compliance rate of the treatmentprotocol and adverse effects arising from the therapy
225 Data Analyses Descriptive statistics were determinedon the sociodemographic and clinical characteristics of the
subjects The estimated mean and standard error were com-puted for the outcome variables of each time point Associa-tion amongst categorical variables was estimated using x2 testor Fisherrsquos exact test where appropriate to identify significantvariables for inclusion in the generalised estimating equa-tions (GEE) for adjustment One-way analysis of variancewas used to examine group differences Primary analysiswas conducted using GEE model with an autoregressioncorrelation structure to evaluate interactions amongst thegroups over time (baseline to six months follow-up) on theprimary outcome (ie PSQI score) and secondary outcomes(sleep parameters using 24-hour actigraphic monitoringquality of life using SF-12 and PHQ-9) Missing data werehandled usingGEE and assumed to be random [32]Themainanalysis was repeated at postintervention and during thefollow-up sessions (up to six months) for sensitivity analysisSPSS version 250 (IBM Corporation USA) was used for allstatistical analyses All statistical tests were two sided withsignificance level set at 005
3 Results
The study was conducted from May 2016 to May 2018Data were collected from 11 centres for the elderly and therecruitment rate was 886 A total of 147 eligible subjectswere randomly divided into three groups (Group 1=50Group2=46 and Group 3=51)
31 Participantsrsquo Characteristics The recruited subjects hadan average age of 7529 yearsplusmn 699 with a mean durationof insomnia for 1012 plusmn 1067 years Majority of the subjects(700) did not take any medication to manage their sleepproblems The groups were essentially comparable and wellbalanced in terms of sociodemographic variables includ-ing gender distribution body mass index education level

marital status comorbid illnesses and regular medicationstaken However age showed slight significant differencesamongst the groups and thus this variable was adjusted inthe GEE models in subsequent analyses According to the24-hour actigraphic recordings the subjects had an averageof poor sleep quality (PSQI 1263 plusmn324 sleep efficiency7233 plusmn1609) long sleep latency (2703 plusmn 2313 minutes)short total sleep time (376 plusmn 196 hours) and waking aftersleep onset (9031plusmn 8853minutes)The subjects also hadmilddepression (PHQ-9 947 plusmn 607) and low HRQOL in termsof physical component (4139 plusmn 851) and mental component(4668 plusmn 1234) (Table 1)
32 Compliance Expectation and Satisfaction towards theTreatment Compliance with the intervention protocol washigh at an average of 952 (n = 140) of the subjects contin-ued with postintervention and all follow-up measurementsuntil six months The recruitment flowchart is illustrated inFigure 4 Althoughmajority of the subjects (653) had nevertried complementary and alternative treatments they gener-ally exhibited strong confidence in the proposed therapy (782of 10) and had a relatively high expectation of its effectiveness(773 of 10) before the trial After the intervention the subjectsin Group 1 had the highest satisfaction from the therapy(786) followed by those in Group 3 (758) and Group 2 (702)A correlation analysis was conducted between expectationsof the treatment effect and sleep parameters (PSQI SE)However no significant relationship was detected (pgt005)Over 75 of the subjects (n = 109) indicated that they woulddefinitely recommend the therapy to others No specificadverse effects were observed arising from the therapyapart from 16 cases (109) who reported having mild skinirritation on the ears due to the adhesive tapes that were usedto hold the experimental tools in place and 20 cases (136)who felt tenderness on the acupoints (most of these subjectsreceived MAT) The number of subjects who believed thatthey might be receiving placebo treatment was higher inGroup 1 than in the other groups although majority of thesubjects (90) believed that they were not receiving placebo(Table 2)
33 Treatment Effect The differences in the primary andsecondary outcomes of the three groups across differenttime points were compared through GEE model analysiswith adjustment for age In general no significant differ-ences were detected in the outcomes (including PSQI sleepparameters measured by actigraphic monitoring SF-12 andPHQ-9) of the three groups (Table 3) However significantdifferences were found in all of the subjective measuresincluding PSQI (Figure 5) SF-12 (physical andor mentalcomponents) (Figures S1 and S2) and PHQ-9 (Figure 6) forindividual groups over time When the sleep conditions wereevaluated by actigraphic monitoring significant differencesin lsquowaking after sleep onsetrsquo (minutes) (Figure S3) and lsquosleepefficiencyrsquo () (Figure S4) were detected only in Groups 1and 3 (Table 4) The completersrsquo analysis showed consistentfindings on the primary and secondary outcomes of thetrial
4 Discussion
Numerous studies that used AT to manage sleep problemsin China encountered methodological flaws which renderedtheir findings unconvincingThe commonproblems includedlack of details on how randomisation and allocation conceal-ment were conducted absence of objective measurementsand a control or placebo group as well as failure to report theuse of blinding and selective reporting of findings [33ndash35]The present study was performed using a scientific approachto identify the optimum treatment protocol forAT in improv-ing the sleep conditions and quality of life of the elderlywith insomnia This meticulous randomised controlled trial(RCT) could provide scientific evidence regarding causalrelationships between interventions and outcomes
In general the treatment effect was comparable amongstthe three AT protocols However significant improvementswere observed in all of the subjective measures includingsleep conditions measured by PSQI HRQOL and depressionstatus for individual groups over time When the sleepconditions were evaluated by objective measures using acti-graphic monitoring significant differences in ldquowaking aftersleep onsetrdquo (minutes) and ldquosleep efficiencyrdquo () were onlynoted in Groups 1 and 3 The use of actigraphs has beenwidely recognised as an objective measurement that couldprovide longitudinal assessment of sleep patterns in a naturalenvironment [36 37]This technique could similarly providevalidmeasures thatmay not be influenced by subject bias Sig-nificant reduction in the awakening time after sleep onset andincrease in sleep efficiency were only detected in subjects whoreceived MAT protocols (ie Groups 1 and 3) but not in thosewho received only the LAT protocol Despite the improvedsleep efficiency of the subjects at postintervention and duringthe follow-up periods the evaluated indices remained below85 a common cut-off percentage that indicates the presenceof sleep disturbances [38] Sleep efficiency is calculated bydividing the total sleep time by total bedtime a higher sleepefficiency means better sleep quantity and quality A longtherapeutic course such as 10ndash12 weeks may be necessaryto further elevate sleep efficiency to a desirable level throughsustainable treatment effect
MAT could provide continuous stimulation of acupointsas long as the magnetic pellets on the ears are in situ and thesubjects could receive laser stimulation to the acupoints onthe day of treatment The synergistic effect of the combinedMAT and LAT was demonstrated in two previous trials[39 40] conducted by the research team In a double-blindRCT for osteoarthritic knee the subjects who received thecombined AT protocols exhibited stronger treatment effectsin terms of pain relief ambulation status and range of kneemovements compared with those treated with separate MATor LAT [39] whereas in another double-blinded RCT foraging males with lower urinary tract symptoms a combinedAT protocol exhibited a stronger therapeutic effect in reliev-ing voiding problems improving the urinary flow rate andminimizing the postvoid residual urine than the placebogroup or MAT alone [40] However the combined MAT andLAT approach did not show any advantage over the separateMAT protocol in current studyTherefore a greater frequency

interaction of magnetic fields with blood flow and calciumchannel proteins in the cell membrane Such interactionsmay elicit functional body changes [16 48 49] MeanwhileLAT is a noninvasive alternative to needle acupuncture [22]and has been adopted to increase pain threshold [50] aswell as relieve musculoskeletal pain [18] and insomnia [17]The laser beam not only irradiates and stimulates acupointsbut also triggers the energy flow (qi) and regulates the

functions of internal organs to achieve a therapeutic effect[22]
According to neuroembryonic theory Dr Paul Nogierviewed the auricle as a homunculus of the human bodyand has a similar shape to an inverted foetus [8] As suchappropriate stimulation of specific ear acupoints can achievetherapeutic effects [51] In the present study the selection ofauricular acupoints was based on the TCM theory and ideasborrowed from modern medicine For example treating the
ldquoheartrdquo can calm the mind while soothing the ldquoliverrdquo couldregulate the flow of qi particularly when insomnia is causedby liver qi stagnation [52] ldquoShenmenrdquo and ldquoocciputrdquo arebelieved to tranquilise the mind and the lsquosubcortexrsquo canharmonise cortex excitement and inhibition [12]
A population-based epidemiological study conducted on5000 subjects in Hong Kong reported that insomnia washighly prevalent amongst Chinese adults and was associatedwith poor mental status and quality of life [53] The present
Evidence-Based Complementary and Alternative Medicine 17
study reported PCS scores of the subjects comparable withthose of Hong Kong people with insomnia (4321 in ourstudy versus 4139 population norm) but stated a slightlyhigherMCS (4668 versus 3636)HRQOL (in PCS andMCS)improved and depression declined over time in subjectstreated with AT Thus quality of life and emotional statusof the subjects may be positively associated with sleepimprovement after the therapy
No specific adverse effectswere observed to arise from thetherapy apart from a small number of reported cases (109)having mild skin irritation on the ears from the adhesivetapes used to hold the experimental tools in place Moreover20 cases (136) reported tenderness on the acupoints andmost of these subjects received MAT According to theauricular diagnosis system the areas of the auricle withheightened tenderness upon touching correspond to specificareas of the body where pathological conditions exist [5455] Applying magnetic pellets may induce physical pressureon the ear acupoints and cause tenderness especially incases with disequilibrium of bodily functions (eg insomnia)corresponding to specific acupoints The tenderness on thereflective acupoints experienced by the subjects may beconsidered part of the treatment process rather than adverseeffects of AT
The high compliance rate (952) and positive impres-sion of the therapy indirectly indicated that blinding wassuccessful because of the successful placebo applicationin the trial Over 75 of the participants expressed thatthey would definitely recommend the therapy to othersThe findings of this trial can provide valuable informationand increase understanding of the therapeutic effect of ATwhether separate or combinedMATandLAT Longer therapyduration may be considered in future trials to determinefurther improvements in the outcome variables The pro-posed treatment approach can be considered as a noninvasivestrategy for managing insomnia amongst the elderly
Although actigraphic monitoring is a reliable objectivemeasure in sleep study changes in different sleep stagescaused by the therapy cannot be ascertained The recruitedelders generally obtained low education levels and had amean age of over 75 and therefore using a sleep log toverify the actigraphic data was not feasible Night-to-nightvariability in the sleeping patterns of subjects may also beaffected by physical psychological andor environmentalfactors Due to the above limitations the actigraphic datamust be interpreted with caution The exact mechanismsremain unknown regarding the interaction of magnetic fieldswith biological tissues which results in functional changesFurther studies from the biomedical perspective are requiredto elucidate the biological pathway of the treatment and effectsuch as to examine the impact of the treatment protocolson the changes in sleep biomarkers when sleep prosperity isachieved
5 Implications
This study provides valuable findings regarding the therapeu-tic effect of different protocols usingMAT LAT or their com-bination In general the AT protocols under testing may be
considered as a noninvasive approach with minimal adverseeffects for managing sleep problems amongst the elderlyThe findings of this study provide important implications toguide future research and apply evidence-based practice inthe community via service provision tomanage this commonproblem
6 Conclusion
The treatment effects of the three protocols were comparablein terms of self-reported sleep conditions HRQOL anddepression status In several parameters such therapeuticeffects may be sustained at six-month follow-up Significantimprovement in the objective sleep parameters could beobserved in subjects who received MAT protocols but notin those who received LAT The combined MAT and LATapproach did not show any advantage over MAT Longertherapeutic course and more frequent administration of LATmay be considered in future trials to achieve the optimaltreatment effect In general the proposed AT protocolswere demonstrated to be a well-received treatment modalitywith minimal adverse effects and effectively improved sleepconditions of the elderly with insomnia

efficiency () An Actiwatchrsquo Spectrum Plus device with0025G ultra-high sensitivity and 32 Hz sampling rate wasused in actigraphic monitoring The subjects were requestedto wear the device on the wrist of their nondominant hand 24hours a day for 7 consecutive days to determine the overallsleep conditions within a certain period Data were collectedin epochs every 30 second These epoch-by-epoch data werestored in the internal memory of the device until theycould be downloaded to a computer Actiware 6 ActigraphAnalysis Software was used for sleep analysis (2)TheChinese(HK) SF-12 v2copy an abbreviated version of the SF36 healthquestionnaire was used to evaluate the health-related qualityof life (HRQOL) of the subjects This instrument covered 12items and the resultswere presented by a physical componentscore (PCS) and a mental component score (MCS) PCS andMCS ranged from 0 to 100 with higher scores indicatingbetter HRQOL [28] (3) Patient Health Questionnaire (PHQ-9) was also used This instrument was validated as a usefultool for assessing depression status The scores ranged from0 to 27 and high scores indicated severe depression status[29] The scale had a Cronbachrsquos alpha of 082 and therecommended cut-off score was 8 [30]
The subjectsrsquo expectations and satisfaction towards thetherapy were evaluated using a 10-point scale with highscores indicating high expectations or satisfaction [31] Datawere likewise collected on sociodemographic characteris-tics including age gender marital status educational levelreligion number of family members body mass indexsingleshared bed comorbid illnesses use of sleeping pillsor aids and current medications taken Similarly monitoredwere the recruitment rate compliance rate of the treatmentprotocol and adverse effects arising from the therapy

subjects The estimated mean and standard error were com-puted for the outcome variables of each time point Associa-tion amongst categorical variables was estimated using x2 testor Fisherrsquos exact test where appropriate to identify significantvariables for inclusion in the generalised estimating equa-tions (GEE) for adjustment One-way analysis of variancewas used to examine group differences Primary analysiswas conducted using GEE model with an autoregressioncorrelation structure to evaluate interactions amongst thegroups over time (baseline to six months follow-up) on theprimary outcome (ie PSQI score) and secondary outcomes(sleep parameters using 24-hour actigraphic monitoringquality of life using SF-12 and PHQ-9) Missing data werehandled usingGEE and assumed to be random [32]Themainanalysis was repeated at postintervention and during thefollow-up sessions (up to six months) for sensitivity analysisSPSS version 250 (IBM Corporation USA) was used for allstatistical analyses All statistical tests were two sided withsignificance level set at 005
3 Results
The study was conducted from May 2016 to May 2018Data were collected from 11 centres for the elderly and therecruitment rate was 886 A total of 147 eligible subjectswere randomly divided into three groups (Group 1=50Group2=46 and Group 3=51)
31 Participantsrsquo Characteristics The recruited subjects hadan average age of 7529 yearsplusmn 699 with a mean durationof insomnia for 1012 plusmn 1067 years Majority of the subjects(700) did not take any medication to manage their sleepproblems The groups were essentially comparable and wellbalanced in terms of sociodemographic variables includ-ing gender distribution body mass index education level

marital status comorbid illnesses and regular medicationstaken However age showed slight significant differencesamongst the groups and thus this variable was adjusted inthe GEE models in subsequent analyses According to the24-hour actigraphic recordings the subjects had an averageof poor sleep quality (PSQI 1263 plusmn324 sleep efficiency7233 plusmn1609) long sleep latency (2703 plusmn 2313 minutes)short total sleep time (376 plusmn 196 hours) and waking aftersleep onset (9031plusmn 8853minutes)The subjects also hadmilddepression (PHQ-9 947 plusmn 607) and low HRQOL in termsof physical component (4139 plusmn 851) and mental component(4668 plusmn 1234) (Table 1)
32 Compliance Expectation and Satisfaction towards theTreatment Compliance with the intervention protocol washigh at an average of 952 (n = 140) of the subjects contin-ued with postintervention and all follow-up measurementsuntil six months The recruitment flowchart is illustrated inFigure 4 Althoughmajority of the subjects (653) had nevertried complementary and alternative treatments they gener-ally exhibited strong confidence in the proposed therapy (782of 10) and had a relatively high expectation of its effectiveness(773 of 10) before the trial After the intervention the subjectsin Group 1 had the highest satisfaction from the therapy(786) followed by those in Group 3 (758) and Group 2 (702)A correlation analysis was conducted between expectationsof the treatment effect and sleep parameters (PSQI SE)However no significant relationship was detected (pgt005)Over 75 of the subjects (n = 109) indicated that they woulddefinitely recommend the therapy to others No specificadverse effects were observed arising from the therapyapart from 16 cases (109) who reported having mild skinirritation on the ears due to the adhesive tapes that were usedto hold the experimental tools in place and 20 cases (136)who felt tenderness on the acupoints (most of these subjectsreceived MAT) The number of subjects who believed thatthey might be receiving placebo treatment was higher inGroup 1 than in the other groups although majority of thesubjects (90) believed that they were not receiving placebo(Table 2)
33 Treatment Effect The differences in the primary andsecondary outcomes of the three groups across differenttime points were compared through GEE model analysiswith adjustment for age In general no significant differ-ences were detected in the outcomes (including PSQI sleepparameters measured by actigraphic monitoring SF-12 andPHQ-9) of the three groups (Table 3) However significantdifferences were found in all of the subjective measuresincluding PSQI (Figure 5) SF-12 (physical andor mentalcomponents) (Figures S1 and S2) and PHQ-9 (Figure 6) forindividual groups over time When the sleep conditions wereevaluated by actigraphic monitoring significant differencesin lsquowaking after sleep onsetrsquo (minutes) (Figure S3) and lsquosleepefficiencyrsquo () (Figure S4) were detected only in Groups 1and 3 (Table 4) The completersrsquo analysis showed consistentfindings on the primary and secondary outcomes of thetrial
4 Discussion
Numerous studies that used AT to manage sleep problemsin China encountered methodological flaws which renderedtheir findings unconvincingThe commonproblems includedlack of details on how randomisation and allocation conceal-ment were conducted absence of objective measurementsand a control or placebo group as well as failure to report theuse of blinding and selective reporting of findings [33ndash35]The present study was performed using a scientific approachto identify the optimum treatment protocol forAT in improv-ing the sleep conditions and quality of life of the elderlywith insomnia This meticulous randomised controlled trial(RCT) could provide scientific evidence regarding causalrelationships between interventions and outcomes
In general the treatment effect was comparable amongstthe three AT protocols However significant improvementswere observed in all of the subjective measures includingsleep conditions measured by PSQI HRQOL and depressionstatus for individual groups over time When the sleepconditions were evaluated by objective measures using acti-graphic monitoring significant differences in ldquowaking aftersleep onsetrdquo (minutes) and ldquosleep efficiencyrdquo () were onlynoted in Groups 1 and 3 The use of actigraphs has beenwidely recognised as an objective measurement that couldprovide longitudinal assessment of sleep patterns in a naturalenvironment [36 37]This technique could similarly providevalidmeasures thatmay not be influenced by subject bias Sig-nificant reduction in the awakening time after sleep onset andincrease in sleep efficiency were only detected in subjects whoreceived MAT protocols (ie Groups 1 and 3) but not in thosewho received only the LAT protocol Despite the improvedsleep efficiency of the subjects at postintervention and duringthe follow-up periods the evaluated indices remained below85 a common cut-off percentage that indicates the presenceof sleep disturbances [38] Sleep efficiency is calculated bydividing the total sleep time by total bedtime a higher sleepefficiency means better sleep quantity and quality A longtherapeutic course such as 10ndash12 weeks may be necessaryto further elevate sleep efficiency to a desirable level throughsustainable treatment effect
MAT could provide continuous stimulation of acupointsas long as the magnetic pellets on the ears are in situ and thesubjects could receive laser stimulation to the acupoints onthe day of treatment The synergistic effect of the combinedMAT and LAT was demonstrated in two previous trials[39 40] conducted by the research team In a double-blindRCT for osteoarthritic knee the subjects who received thecombined AT protocols exhibited stronger treatment effectsin terms of pain relief ambulation status and range of kneemovements compared with those treated with separate MATor LAT [39] whereas in another double-blinded RCT foraging males with lower urinary tract symptoms a combinedAT protocol exhibited a stronger therapeutic effect in reliev-ing voiding problems improving the urinary flow rate andminimizing the postvoid residual urine than the placebogroup or MAT alone [40] However the combined MAT andLAT approach did not show any advantage over the separateMAT protocol in current studyTherefore a greater frequency

for LAT administration such as daily application adoptedin previous studies [41ndash44] may be considered in futurestudies to enhance the treatment effect and possibly improveits synergistic effect when combined with MAT
Numerous clinical trials reported the use of MAT ondifferent disorders including but not limited to sleep dis-turbances [12 45 46] low back pain [13] constipation [14]and obesity [47] The effectiveness of MAT may relate to the
interaction of magnetic fields with blood flow and calciumchannel proteins in the cell membrane Such interactionsmay elicit functional body changes [16 48 49] MeanwhileLAT is a noninvasive alternative to needle acupuncture [22]and has been adopted to increase pain threshold [50] aswell as relieve musculoskeletal pain [18] and insomnia [17]The laser beam not only irradiates and stimulates acupointsbut also triggers the energy flow (qi) and regulates the

functions of internal organs to achieve a therapeutic effect[22]
According to neuroembryonic theory Dr Paul Nogierviewed the auricle as a homunculus of the human bodyand has a similar shape to an inverted foetus [8] As suchappropriate stimulation of specific ear acupoints can achievetherapeutic effects [51] In the present study the selection ofauricular acupoints was based on the TCM theory and ideasborrowed from modern medicine For example treating the
ldquoheartrdquo can calm the mind while soothing the ldquoliverrdquo couldregulate the flow of qi particularly when insomnia is causedby liver qi stagnation [52] ldquoShenmenrdquo and ldquoocciputrdquo arebelieved to tranquilise the mind and the lsquosubcortexrsquo canharmonise cortex excitement and inhibition [12]
A population-based epidemiological study conducted on5000 subjects in Hong Kong reported that insomnia washighly prevalent amongst Chinese adults and was associatedwith poor mental status and quality of life [53] The present
Evidence-Based Complementary and Alternative Medicine 17
study reported PCS scores of the subjects comparable withthose of Hong Kong people with insomnia (4321 in ourstudy versus 4139 population norm) but stated a slightlyhigherMCS (4668 versus 3636)HRQOL (in PCS andMCS)improved and depression declined over time in subjectstreated with AT Thus quality of life and emotional statusof the subjects may be positively associated with sleepimprovement after the therapy
No specific adverse effectswere observed to arise from thetherapy apart from a small number of reported cases (109)having mild skin irritation on the ears from the adhesivetapes used to hold the experimental tools in place Moreover20 cases (136) reported tenderness on the acupoints andmost of these subjects received MAT According to theauricular diagnosis system the areas of the auricle withheightened tenderness upon touching correspond to specificareas of the body where pathological conditions exist [5455] Applying magnetic pellets may induce physical pressureon the ear acupoints and cause tenderness especially incases with disequilibrium of bodily functions (eg insomnia)corresponding to specific acupoints The tenderness on thereflective acupoints experienced by the subjects may beconsidered part of the treatment process rather than adverseeffects of AT
The high compliance rate (952) and positive impres-sion of the therapy indirectly indicated that blinding wassuccessful because of the successful placebo applicationin the trial Over 75 of the participants expressed thatthey would definitely recommend the therapy to othersThe findings of this trial can provide valuable informationand increase understanding of the therapeutic effect of ATwhether separate or combinedMATandLAT Longer therapyduration may be considered in future trials to determinefurther improvements in the outcome variables The pro-posed treatment approach can be considered as a noninvasivestrategy for managing insomnia amongst the elderly
Although actigraphic monitoring is a reliable objectivemeasure in sleep study changes in different sleep stagescaused by the therapy cannot be ascertained The recruitedelders generally obtained low education levels and had amean age of over 75 and therefore using a sleep log toverify the actigraphic data was not feasible Night-to-nightvariability in the sleeping patterns of subjects may also beaffected by physical psychological andor environmentalfactors Due to the above limitations the actigraphic datamust be interpreted with caution The exact mechanismsremain unknown regarding the interaction of magnetic fieldswith biological tissues which results in functional changesFurther studies from the biomedical perspective are requiredto elucidate the biological pathway of the treatment and effectsuch as to examine the impact of the treatment protocolson the changes in sleep biomarkers when sleep prosperity isachieved
5 Implications
This study provides valuable findings regarding the therapeu-tic effect of different protocols usingMAT LAT or their com-bination In general the AT protocols under testing may be
considered as a noninvasive approach with minimal adverseeffects for managing sleep problems amongst the elderlyThe findings of this study provide important implications toguide future research and apply evidence-based practice inthe community via service provision tomanage this commonproblem
6 Conclusion
The treatment effects of the three protocols were comparablein terms of self-reported sleep conditions HRQOL anddepression status In several parameters such therapeuticeffects may be sustained at six-month follow-up Significantimprovement in the objective sleep parameters could beobserved in subjects who received MAT protocols but notin those who received LAT The combined MAT and LATapproach did not show any advantage over MAT Longertherapeutic course and more frequent administration of LATmay be considered in future trials to achieve the optimaltreatment effect In general the proposed AT protocolswere demonstrated to be a well-received treatment modalitywith minimal adverse effects and effectively improved sleepconditions of the elderly with insomnia

marital status comorbid illnesses and regular medicationstaken However age showed slight significant differencesamongst the groups and thus this variable was adjusted inthe GEE models in subsequent analyses According to the24-hour actigraphic recordings the subjects had an averageof poor sleep quality (PSQI 1263 plusmn324 sleep efficiency7233 plusmn1609) long sleep latency (2703 plusmn 2313 minutes)short total sleep time (376 plusmn 196 hours) and waking aftersleep onset (9031plusmn 8853minutes)The subjects also hadmilddepression (PHQ-9 947 plusmn 607) and low HRQOL in termsof physical component (4139 plusmn 851) and mental component(4668 plusmn 1234) (Table 1)
32 Compliance Expectation and Satisfaction towards theTreatment Compliance with the intervention protocol washigh at an average of 952 (n = 140) of the subjects contin-ued with postintervention and all follow-up measurementsuntil six months The recruitment flowchart is illustrated inFigure 4 Althoughmajority of the subjects (653) had nevertried complementary and alternative treatments they gener-ally exhibited strong confidence in the proposed therapy (782of 10) and had a relatively high expectation of its effectiveness(773 of 10) before the trial After the intervention the subjectsin Group 1 had the highest satisfaction from the therapy(786) followed by those in Group 3 (758) and Group 2 (702)A correlation analysis was conducted between expectationsof the treatment effect and sleep parameters (PSQI SE)However no significant relationship was detected (pgt005)Over 75 of the subjects (n = 109) indicated that they woulddefinitely recommend the therapy to others No specificadverse effects were observed arising from the therapyapart from 16 cases (109) who reported having mild skinirritation on the ears due to the adhesive tapes that were usedto hold the experimental tools in place and 20 cases (136)who felt tenderness on the acupoints (most of these subjectsreceived MAT) The number of subjects who believed thatthey might be receiving placebo treatment was higher inGroup 1 than in the other groups although majority of thesubjects (90) believed that they were not receiving placebo(Table 2)
33 Treatment Effect The differences in the primary andsecondary outcomes of the three groups across differenttime points were compared through GEE model analysiswith adjustment for age In general no significant differ-ences were detected in the outcomes (including PSQI sleepparameters measured by actigraphic monitoring SF-12 andPHQ-9) of the three groups (Table 3) However significantdifferences were found in all of the subjective measuresincluding PSQI (Figure 5) SF-12 (physical andor mentalcomponents) (Figures S1 and S2) and PHQ-9 (Figure 6) forindividual groups over time When the sleep conditions wereevaluated by actigraphic monitoring significant differencesin lsquowaking after sleep onsetrsquo (minutes) (Figure S3) and lsquosleepefficiencyrsquo () (Figure S4) were detected only in Groups 1and 3 (Table 4) The completersrsquo analysis showed consistentfindings on the primary and secondary outcomes of thetrial
4 Discussion
Numerous studies that used AT to manage sleep problemsin China encountered methodological flaws which renderedtheir findings unconvincingThe commonproblems includedlack of details on how randomisation and allocation conceal-ment were conducted absence of objective measurementsand a control or placebo group as well as failure to report theuse of blinding and selective reporting of findings [33ndash35]The present study was performed using a scientific approachto identify the optimum treatment protocol forAT in improv-ing the sleep conditions and quality of life of the elderlywith insomnia This meticulous randomised controlled trial(RCT) could provide scientific evidence regarding causalrelationships between interventions and outcomes
In general the treatment effect was comparable amongstthe three AT protocols However significant improvementswere observed in all of the subjective measures includingsleep conditions measured by PSQI HRQOL and depressionstatus for individual groups over time When the sleepconditions were evaluated by objective measures using acti-graphic monitoring significant differences in ldquowaking aftersleep onsetrdquo (minutes) and ldquosleep efficiencyrdquo () were onlynoted in Groups 1 and 3 The use of actigraphs has beenwidely recognised as an objective measurement that couldprovide longitudinal assessment of sleep patterns in a naturalenvironment [36 37]This technique could similarly providevalidmeasures thatmay not be influenced by subject bias Sig-nificant reduction in the awakening time after sleep onset andincrease in sleep efficiency were only detected in subjects whoreceived MAT protocols (ie Groups 1 and 3) but not in thosewho received only the LAT protocol Despite the improvedsleep efficiency of the subjects at postintervention and duringthe follow-up periods the evaluated indices remained below85 a common cut-off percentage that indicates the presenceof sleep disturbances [38] Sleep efficiency is calculated bydividing the total sleep time by total bedtime a higher sleepefficiency means better sleep quantity and quality A longtherapeutic course such as 10ndash12 weeks may be necessaryto further elevate sleep efficiency to a desirable level throughsustainable treatment effect
MAT could provide continuous stimulation of acupointsas long as the magnetic pellets on the ears are in situ and thesubjects could receive laser stimulation to the acupoints onthe day of treatment The synergistic effect of the combinedMAT and LAT was demonstrated in two previous trials[39 40] conducted by the research team In a double-blindRCT for osteoarthritic knee the subjects who received thecombined AT protocols exhibited stronger treatment effectsin terms of pain relief ambulation status and range of kneemovements compared with those treated with separate MATor LAT [39] whereas in another double-blinded RCT foraging males with lower urinary tract symptoms a combinedAT protocol exhibited a stronger therapeutic effect in reliev-ing voiding problems improving the urinary flow rate andminimizing the postvoid residual urine than the placebogroup or MAT alone [40] However the combined MAT andLAT approach did not show any advantage over the separateMAT protocol in current studyTherefore a greater frequency

for LAT administration such as daily application adoptedin previous studies [41ndash44] may be considered in futurestudies to enhance the treatment effect and possibly improveits synergistic effect when combined with MAT
Numerous clinical trials reported the use of MAT ondifferent disorders including but not limited to sleep dis-turbances [12 45 46] low back pain [13] constipation [14]and obesity [47] The effectiveness of MAT may relate to the
interaction of magnetic fields with blood flow and calciumchannel proteins in the cell membrane Such interactionsmay elicit functional body changes [16 48 49] MeanwhileLAT is a noninvasive alternative to needle acupuncture [22]and has been adopted to increase pain threshold [50] aswell as relieve musculoskeletal pain [18] and insomnia [17]The laser beam not only irradiates and stimulates acupointsbut also triggers the energy flow (qi) and regulates the

functions of internal organs to achieve a therapeutic effect[22]
According to neuroembryonic theory Dr Paul Nogierviewed the auricle as a homunculus of the human bodyand has a similar shape to an inverted foetus [8] As suchappropriate stimulation of specific ear acupoints can achievetherapeutic effects [51] In the present study the selection ofauricular acupoints was based on the TCM theory and ideasborrowed from modern medicine For example treating the
ldquoheartrdquo can calm the mind while soothing the ldquoliverrdquo couldregulate the flow of qi particularly when insomnia is causedby liver qi stagnation [52] ldquoShenmenrdquo and ldquoocciputrdquo arebelieved to tranquilise the mind and the lsquosubcortexrsquo canharmonise cortex excitement and inhibition [12]
A population-based epidemiological study conducted on5000 subjects in Hong Kong reported that insomnia washighly prevalent amongst Chinese adults and was associatedwith poor mental status and quality of life [53] The present
Evidence-Based Complementary and Alternative Medicine 17
study reported PCS scores of the subjects comparable withthose of Hong Kong people with insomnia (4321 in ourstudy versus 4139 population norm) but stated a slightlyhigherMCS (4668 versus 3636)HRQOL (in PCS andMCS)improved and depression declined over time in subjectstreated with AT Thus quality of life and emotional statusof the subjects may be positively associated with sleepimprovement after the therapy
No specific adverse effectswere observed to arise from thetherapy apart from a small number of reported cases (109)having mild skin irritation on the ears from the adhesivetapes used to hold the experimental tools in place Moreover20 cases (136) reported tenderness on the acupoints andmost of these subjects received MAT According to theauricular diagnosis system the areas of the auricle withheightened tenderness upon touching correspond to specificareas of the body where pathological conditions exist [5455] Applying magnetic pellets may induce physical pressureon the ear acupoints and cause tenderness especially incases with disequilibrium of bodily functions (eg insomnia)corresponding to specific acupoints The tenderness on thereflective acupoints experienced by the subjects may beconsidered part of the treatment process rather than adverseeffects of AT
The high compliance rate (952) and positive impres-sion of the therapy indirectly indicated that blinding wassuccessful because of the successful placebo applicationin the trial Over 75 of the participants expressed thatthey would definitely recommend the therapy to othersThe findings of this trial can provide valuable informationand increase understanding of the therapeutic effect of ATwhether separate or combinedMATandLAT Longer therapyduration may be considered in future trials to determinefurther improvements in the outcome variables The pro-posed treatment approach can be considered as a noninvasivestrategy for managing insomnia amongst the elderly
Although actigraphic monitoring is a reliable objectivemeasure in sleep study changes in different sleep stagescaused by the therapy cannot be ascertained The recruitedelders generally obtained low education levels and had amean age of over 75 and therefore using a sleep log toverify the actigraphic data was not feasible Night-to-nightvariability in the sleeping patterns of subjects may also beaffected by physical psychological andor environmentalfactors Due to the above limitations the actigraphic datamust be interpreted with caution The exact mechanismsremain unknown regarding the interaction of magnetic fieldswith biological tissues which results in functional changesFurther studies from the biomedical perspective are requiredto elucidate the biological pathway of the treatment and effectsuch as to examine the impact of the treatment protocolson the changes in sleep biomarkers when sleep prosperity isachieved
5 Implications
This study provides valuable findings regarding the therapeu-tic effect of different protocols usingMAT LAT or their com-bination In general the AT protocols under testing may be
considered as a noninvasive approach with minimal adverseeffects for managing sleep problems amongst the elderlyThe findings of this study provide important implications toguide future research and apply evidence-based practice inthe community via service provision tomanage this commonproblem
6 Conclusion
The treatment effects of the three protocols were comparablein terms of self-reported sleep conditions HRQOL anddepression status In several parameters such therapeuticeffects may be sustained at six-month follow-up Significantimprovement in the objective sleep parameters could beobserved in subjects who received MAT protocols but notin those who received LAT The combined MAT and LATapproach did not show any advantage over MAT Longertherapeutic course and more frequent administration of LATmay be considered in future trials to achieve the optimaltreatment effect In general the proposed AT protocolswere demonstrated to be a well-received treatment modalitywith minimal adverse effects and effectively improved sleepconditions of the elderly with insomnia

for LAT administration such as daily application adoptedin previous studies [41ndash44] may be considered in futurestudies to enhance the treatment effect and possibly improveits synergistic effect when combined with MAT
Numerous clinical trials reported the use of MAT ondifferent disorders including but not limited to sleep dis-turbances [12 45 46] low back pain [13] constipation [14]and obesity [47] The effectiveness of MAT may relate to the
interaction of magnetic fields with blood flow and calciumchannel proteins in the cell membrane Such interactionsmay elicit functional body changes [16 48 49] MeanwhileLAT is a noninvasive alternative to needle acupuncture [22]and has been adopted to increase pain threshold [50] aswell as relieve musculoskeletal pain [18] and insomnia [17]The laser beam not only irradiates and stimulates acupointsbut also triggers the energy flow (qi) and regulates the

functions of internal organs to achieve a therapeutic effect[22]
According to neuroembryonic theory Dr Paul Nogierviewed the auricle as a homunculus of the human bodyand has a similar shape to an inverted foetus [8] As suchappropriate stimulation of specific ear acupoints can achievetherapeutic effects [51] In the present study the selection ofauricular acupoints was based on the TCM theory and ideasborrowed from modern medicine For example treating the
ldquoheartrdquo can calm the mind while soothing the ldquoliverrdquo couldregulate the flow of qi particularly when insomnia is causedby liver qi stagnation [52] ldquoShenmenrdquo and ldquoocciputrdquo arebelieved to tranquilise the mind and the lsquosubcortexrsquo canharmonise cortex excitement and inhibition [12]
A population-based epidemiological study conducted on5000 subjects in Hong Kong reported that insomnia washighly prevalent amongst Chinese adults and was associatedwith poor mental status and quality of life [53] The present
Evidence-Based Complementary and Alternative Medicine 17
study reported PCS scores of the subjects comparable withthose of Hong Kong people with insomnia (4321 in ourstudy versus 4139 population norm) but stated a slightlyhigherMCS (4668 versus 3636)HRQOL (in PCS andMCS)improved and depression declined over time in subjectstreated with AT Thus quality of life and emotional statusof the subjects may be positively associated with sleepimprovement after the therapy
No specific adverse effectswere observed to arise from thetherapy apart from a small number of reported cases (109)having mild skin irritation on the ears from the adhesivetapes used to hold the experimental tools in place Moreover20 cases (136) reported tenderness on the acupoints andmost of these subjects received MAT According to theauricular diagnosis system the areas of the auricle withheightened tenderness upon touching correspond to specificareas of the body where pathological conditions exist [5455] Applying magnetic pellets may induce physical pressureon the ear acupoints and cause tenderness especially incases with disequilibrium of bodily functions (eg insomnia)corresponding to specific acupoints The tenderness on thereflective acupoints experienced by the subjects may beconsidered part of the treatment process rather than adverseeffects of AT
The high compliance rate (952) and positive impres-sion of the therapy indirectly indicated that blinding wassuccessful because of the successful placebo applicationin the trial Over 75 of the participants expressed thatthey would definitely recommend the therapy to othersThe findings of this trial can provide valuable informationand increase understanding of the therapeutic effect of ATwhether separate or combinedMATandLAT Longer therapyduration may be considered in future trials to determinefurther improvements in the outcome variables The pro-posed treatment approach can be considered as a noninvasivestrategy for managing insomnia amongst the elderly
Although actigraphic monitoring is a reliable objectivemeasure in sleep study changes in different sleep stagescaused by the therapy cannot be ascertained The recruitedelders generally obtained low education levels and had amean age of over 75 and therefore using a sleep log toverify the actigraphic data was not feasible Night-to-nightvariability in the sleeping patterns of subjects may also beaffected by physical psychological andor environmentalfactors Due to the above limitations the actigraphic datamust be interpreted with caution The exact mechanismsremain unknown regarding the interaction of magnetic fieldswith biological tissues which results in functional changesFurther studies from the biomedical perspective are requiredto elucidate the biological pathway of the treatment and effectsuch as to examine the impact of the treatment protocolson the changes in sleep biomarkers when sleep prosperity isachieved
5 Implications
This study provides valuable findings regarding the therapeu-tic effect of different protocols usingMAT LAT or their com-bination In general the AT protocols under testing may be
considered as a noninvasive approach with minimal adverseeffects for managing sleep problems amongst the elderlyThe findings of this study provide important implications toguide future research and apply evidence-based practice inthe community via service provision tomanage this commonproblem
6 Conclusion
The treatment effects of the three protocols were comparablein terms of self-reported sleep conditions HRQOL anddepression status In several parameters such therapeuticeffects may be sustained at six-month follow-up Significantimprovement in the objective sleep parameters could beobserved in subjects who received MAT protocols but notin those who received LAT The combined MAT and LATapproach did not show any advantage over MAT Longertherapeutic course and more frequent administration of LATmay be considered in future trials to achieve the optimaltreatment effect In general the proposed AT protocolswere demonstrated to be a well-received treatment modalitywith minimal adverse effects and effectively improved sleepconditions of the elderly with insomnia

for LAT administration such as daily application adoptedin previous studies [41ndash44] may be considered in futurestudies to enhance the treatment effect and possibly improveits synergistic effect when combined with MAT
Numerous clinical trials reported the use of MAT ondifferent disorders including but not limited to sleep dis-turbances [12 45 46] low back pain [13] constipation [14]and obesity [47] The effectiveness of MAT may relate to the
interaction of magnetic fields with blood flow and calciumchannel proteins in the cell membrane Such interactionsmay elicit functional body changes [16 48 49] MeanwhileLAT is a noninvasive alternative to needle acupuncture [22]and has been adopted to increase pain threshold [50] aswell as relieve musculoskeletal pain [18] and insomnia [17]The laser beam not only irradiates and stimulates acupointsbut also triggers the energy flow (qi) and regulates the

functions of internal organs to achieve a therapeutic effect[22]
According to neuroembryonic theory Dr Paul Nogierviewed the auricle as a homunculus of the human bodyand has a similar shape to an inverted foetus [8] As suchappropriate stimulation of specific ear acupoints can achievetherapeutic effects [51] In the present study the selection ofauricular acupoints was based on the TCM theory and ideasborrowed from modern medicine For example treating the
ldquoheartrdquo can calm the mind while soothing the ldquoliverrdquo couldregulate the flow of qi particularly when insomnia is causedby liver qi stagnation [52] ldquoShenmenrdquo and ldquoocciputrdquo arebelieved to tranquilise the mind and the lsquosubcortexrsquo canharmonise cortex excitement and inhibition [12]
A population-based epidemiological study conducted on5000 subjects in Hong Kong reported that insomnia washighly prevalent amongst Chinese adults and was associatedwith poor mental status and quality of life [53] The present
Evidence-Based Complementary and Alternative Medicine 17
study reported PCS scores of the subjects comparable withthose of Hong Kong people with insomnia (4321 in ourstudy versus 4139 population norm) but stated a slightlyhigherMCS (4668 versus 3636)HRQOL (in PCS andMCS)improved and depression declined over time in subjectstreated with AT Thus quality of life and emotional statusof the subjects may be positively associated with sleepimprovement after the therapy
No specific adverse effectswere observed to arise from thetherapy apart from a small number of reported cases (109)having mild skin irritation on the ears from the adhesivetapes used to hold the experimental tools in place Moreover20 cases (136) reported tenderness on the acupoints andmost of these subjects received MAT According to theauricular diagnosis system the areas of the auricle withheightened tenderness upon touching correspond to specificareas of the body where pathological conditions exist [5455] Applying magnetic pellets may induce physical pressureon the ear acupoints and cause tenderness especially incases with disequilibrium of bodily functions (eg insomnia)corresponding to specific acupoints The tenderness on thereflective acupoints experienced by the subjects may beconsidered part of the treatment process rather than adverseeffects of AT
The high compliance rate (952) and positive impres-sion of the therapy indirectly indicated that blinding wassuccessful because of the successful placebo applicationin the trial Over 75 of the participants expressed thatthey would definitely recommend the therapy to othersThe findings of this trial can provide valuable informationand increase understanding of the therapeutic effect of ATwhether separate or combinedMATandLAT Longer therapyduration may be considered in future trials to determinefurther improvements in the outcome variables The pro-posed treatment approach can be considered as a noninvasivestrategy for managing insomnia amongst the elderly
Although actigraphic monitoring is a reliable objectivemeasure in sleep study changes in different sleep stagescaused by the therapy cannot be ascertained The recruitedelders generally obtained low education levels and had amean age of over 75 and therefore using a sleep log toverify the actigraphic data was not feasible Night-to-nightvariability in the sleeping patterns of subjects may also beaffected by physical psychological andor environmentalfactors Due to the above limitations the actigraphic datamust be interpreted with caution The exact mechanismsremain unknown regarding the interaction of magnetic fieldswith biological tissues which results in functional changesFurther studies from the biomedical perspective are requiredto elucidate the biological pathway of the treatment and effectsuch as to examine the impact of the treatment protocolson the changes in sleep biomarkers when sleep prosperity isachieved
5 Implications
This study provides valuable findings regarding the therapeu-tic effect of different protocols usingMAT LAT or their com-bination In general the AT protocols under testing may be
considered as a noninvasive approach with minimal adverseeffects for managing sleep problems amongst the elderlyThe findings of this study provide important implications toguide future research and apply evidence-based practice inthe community via service provision tomanage this commonproblem
6 Conclusion
The treatment effects of the three protocols were comparablein terms of self-reported sleep conditions HRQOL anddepression status In several parameters such therapeuticeffects may be sustained at six-month follow-up Significantimprovement in the objective sleep parameters could beobserved in subjects who received MAT protocols but notin those who received LAT The combined MAT and LATapproach did not show any advantage over MAT Longertherapeutic course and more frequent administration of LATmay be considered in future trials to achieve the optimaltreatment effect In general the proposed AT protocolswere demonstrated to be a well-received treatment modalitywith minimal adverse effects and effectively improved sleepconditions of the elderly with insomnia

for LAT administration such as daily application adoptedin previous studies [41ndash44] may be considered in futurestudies to enhance the treatment effect and possibly improveits synergistic effect when combined with MAT
Numerous clinical trials reported the use of MAT ondifferent disorders including but not limited to sleep dis-turbances [12 45 46] low back pain [13] constipation [14]and obesity [47] The effectiveness of MAT may relate to the
interaction of magnetic fields with blood flow and calciumchannel proteins in the cell membrane Such interactionsmay elicit functional body changes [16 48 49] MeanwhileLAT is a noninvasive alternative to needle acupuncture [22]and has been adopted to increase pain threshold [50] aswell as relieve musculoskeletal pain [18] and insomnia [17]The laser beam not only irradiates and stimulates acupointsbut also triggers the energy flow (qi) and regulates the

functions of internal organs to achieve a therapeutic effect[22]
According to neuroembryonic theory Dr Paul Nogierviewed the auricle as a homunculus of the human bodyand has a similar shape to an inverted foetus [8] As suchappropriate stimulation of specific ear acupoints can achievetherapeutic effects [51] In the present study the selection ofauricular acupoints was based on the TCM theory and ideasborrowed from modern medicine For example treating the
ldquoheartrdquo can calm the mind while soothing the ldquoliverrdquo couldregulate the flow of qi particularly when insomnia is causedby liver qi stagnation [52] ldquoShenmenrdquo and ldquoocciputrdquo arebelieved to tranquilise the mind and the lsquosubcortexrsquo canharmonise cortex excitement and inhibition [12]
A population-based epidemiological study conducted on5000 subjects in Hong Kong reported that insomnia washighly prevalent amongst Chinese adults and was associatedwith poor mental status and quality of life [53] The present
Evidence-Based Complementary and Alternative Medicine 17
study reported PCS scores of the subjects comparable withthose of Hong Kong people with insomnia (4321 in ourstudy versus 4139 population norm) but stated a slightlyhigherMCS (4668 versus 3636)HRQOL (in PCS andMCS)improved and depression declined over time in subjectstreated with AT Thus quality of life and emotional statusof the subjects may be positively associated with sleepimprovement after the therapy
No specific adverse effectswere observed to arise from thetherapy apart from a small number of reported cases (109)having mild skin irritation on the ears from the adhesivetapes used to hold the experimental tools in place Moreover20 cases (136) reported tenderness on the acupoints andmost of these subjects received MAT According to theauricular diagnosis system the areas of the auricle withheightened tenderness upon touching correspond to specificareas of the body where pathological conditions exist [5455] Applying magnetic pellets may induce physical pressureon the ear acupoints and cause tenderness especially incases with disequilibrium of bodily functions (eg insomnia)corresponding to specific acupoints The tenderness on thereflective acupoints experienced by the subjects may beconsidered part of the treatment process rather than adverseeffects of AT
The high compliance rate (952) and positive impres-sion of the therapy indirectly indicated that blinding wassuccessful because of the successful placebo applicationin the trial Over 75 of the participants expressed thatthey would definitely recommend the therapy to othersThe findings of this trial can provide valuable informationand increase understanding of the therapeutic effect of ATwhether separate or combinedMATandLAT Longer therapyduration may be considered in future trials to determinefurther improvements in the outcome variables The pro-posed treatment approach can be considered as a noninvasivestrategy for managing insomnia amongst the elderly
Although actigraphic monitoring is a reliable objectivemeasure in sleep study changes in different sleep stagescaused by the therapy cannot be ascertained The recruitedelders generally obtained low education levels and had amean age of over 75 and therefore using a sleep log toverify the actigraphic data was not feasible Night-to-nightvariability in the sleeping patterns of subjects may also beaffected by physical psychological andor environmentalfactors Due to the above limitations the actigraphic datamust be interpreted with caution The exact mechanismsremain unknown regarding the interaction of magnetic fieldswith biological tissues which results in functional changesFurther studies from the biomedical perspective are requiredto elucidate the biological pathway of the treatment and effectsuch as to examine the impact of the treatment protocolson the changes in sleep biomarkers when sleep prosperity isachieved
5 Implications
This study provides valuable findings regarding the therapeu-tic effect of different protocols usingMAT LAT or their com-bination In general the AT protocols under testing may be
considered as a noninvasive approach with minimal adverseeffects for managing sleep problems amongst the elderlyThe findings of this study provide important implications toguide future research and apply evidence-based practice inthe community via service provision tomanage this commonproblem
6 Conclusion
The treatment effects of the three protocols were comparablein terms of self-reported sleep conditions HRQOL anddepression status In several parameters such therapeuticeffects may be sustained at six-month follow-up Significantimprovement in the objective sleep parameters could beobserved in subjects who received MAT protocols but notin those who received LAT The combined MAT and LATapproach did not show any advantage over MAT Longertherapeutic course and more frequent administration of LATmay be considered in future trials to achieve the optimaltreatment effect In general the proposed AT protocolswere demonstrated to be a well-received treatment modalitywith minimal adverse effects and effectively improved sleepconditions of the elderly with insomnia

for LAT administration such as daily application adoptedin previous studies [41ndash44] may be considered in futurestudies to enhance the treatment effect and possibly improveits synergistic effect when combined with MAT
Numerous clinical trials reported the use of MAT ondifferent disorders including but not limited to sleep dis-turbances [12 45 46] low back pain [13] constipation [14]and obesity [47] The effectiveness of MAT may relate to the
interaction of magnetic fields with blood flow and calciumchannel proteins in the cell membrane Such interactionsmay elicit functional body changes [16 48 49] MeanwhileLAT is a noninvasive alternative to needle acupuncture [22]and has been adopted to increase pain threshold [50] aswell as relieve musculoskeletal pain [18] and insomnia [17]The laser beam not only irradiates and stimulates acupointsbut also triggers the energy flow (qi) and regulates the

functions of internal organs to achieve a therapeutic effect[22]
According to neuroembryonic theory Dr Paul Nogierviewed the auricle as a homunculus of the human bodyand has a similar shape to an inverted foetus [8] As suchappropriate stimulation of specific ear acupoints can achievetherapeutic effects [51] In the present study the selection ofauricular acupoints was based on the TCM theory and ideasborrowed from modern medicine For example treating the
ldquoheartrdquo can calm the mind while soothing the ldquoliverrdquo couldregulate the flow of qi particularly when insomnia is causedby liver qi stagnation [52] ldquoShenmenrdquo and ldquoocciputrdquo arebelieved to tranquilise the mind and the lsquosubcortexrsquo canharmonise cortex excitement and inhibition [12]
A population-based epidemiological study conducted on5000 subjects in Hong Kong reported that insomnia washighly prevalent amongst Chinese adults and was associatedwith poor mental status and quality of life [53] The present
Evidence-Based Complementary and Alternative Medicine 17
study reported PCS scores of the subjects comparable withthose of Hong Kong people with insomnia (4321 in ourstudy versus 4139 population norm) but stated a slightlyhigherMCS (4668 versus 3636)HRQOL (in PCS andMCS)improved and depression declined over time in subjectstreated with AT Thus quality of life and emotional statusof the subjects may be positively associated with sleepimprovement after the therapy
No specific adverse effectswere observed to arise from thetherapy apart from a small number of reported cases (109)having mild skin irritation on the ears from the adhesivetapes used to hold the experimental tools in place Moreover20 cases (136) reported tenderness on the acupoints andmost of these subjects received MAT According to theauricular diagnosis system the areas of the auricle withheightened tenderness upon touching correspond to specificareas of the body where pathological conditions exist [5455] Applying magnetic pellets may induce physical pressureon the ear acupoints and cause tenderness especially incases with disequilibrium of bodily functions (eg insomnia)corresponding to specific acupoints The tenderness on thereflective acupoints experienced by the subjects may beconsidered part of the treatment process rather than adverseeffects of AT
The high compliance rate (952) and positive impres-sion of the therapy indirectly indicated that blinding wassuccessful because of the successful placebo applicationin the trial Over 75 of the participants expressed thatthey would definitely recommend the therapy to othersThe findings of this trial can provide valuable informationand increase understanding of the therapeutic effect of ATwhether separate or combinedMATandLAT Longer therapyduration may be considered in future trials to determinefurther improvements in the outcome variables The pro-posed treatment approach can be considered as a noninvasivestrategy for managing insomnia amongst the elderly
Although actigraphic monitoring is a reliable objectivemeasure in sleep study changes in different sleep stagescaused by the therapy cannot be ascertained The recruitedelders generally obtained low education levels and had amean age of over 75 and therefore using a sleep log toverify the actigraphic data was not feasible Night-to-nightvariability in the sleeping patterns of subjects may also beaffected by physical psychological andor environmentalfactors Due to the above limitations the actigraphic datamust be interpreted with caution The exact mechanismsremain unknown regarding the interaction of magnetic fieldswith biological tissues which results in functional changesFurther studies from the biomedical perspective are requiredto elucidate the biological pathway of the treatment and effectsuch as to examine the impact of the treatment protocolson the changes in sleep biomarkers when sleep prosperity isachieved
5 Implications
This study provides valuable findings regarding the therapeu-tic effect of different protocols usingMAT LAT or their com-bination In general the AT protocols under testing may be
considered as a noninvasive approach with minimal adverseeffects for managing sleep problems amongst the elderlyThe findings of this study provide important implications toguide future research and apply evidence-based practice inthe community via service provision tomanage this commonproblem
6 Conclusion
The treatment effects of the three protocols were comparablein terms of self-reported sleep conditions HRQOL anddepression status In several parameters such therapeuticeffects may be sustained at six-month follow-up Significantimprovement in the objective sleep parameters could beobserved in subjects who received MAT protocols but notin those who received LAT The combined MAT and LATapproach did not show any advantage over MAT Longertherapeutic course and more frequent administration of LATmay be considered in future trials to achieve the optimaltreatment effect In general the proposed AT protocolswere demonstrated to be a well-received treatment modalitywith minimal adverse effects and effectively improved sleepconditions of the elderly with insomnia

for LAT administration such as daily application adoptedin previous studies [41ndash44] may be considered in futurestudies to enhance the treatment effect and possibly improveits synergistic effect when combined with MAT
Numerous clinical trials reported the use of MAT ondifferent disorders including but not limited to sleep dis-turbances [12 45 46] low back pain [13] constipation [14]and obesity [47] The effectiveness of MAT may relate to the
interaction of magnetic fields with blood flow and calciumchannel proteins in the cell membrane Such interactionsmay elicit functional body changes [16 48 49] MeanwhileLAT is a noninvasive alternative to needle acupuncture [22]and has been adopted to increase pain threshold [50] aswell as relieve musculoskeletal pain [18] and insomnia [17]The laser beam not only irradiates and stimulates acupointsbut also triggers the energy flow (qi) and regulates the

functions of internal organs to achieve a therapeutic effect[22]
According to neuroembryonic theory Dr Paul Nogierviewed the auricle as a homunculus of the human bodyand has a similar shape to an inverted foetus [8] As suchappropriate stimulation of specific ear acupoints can achievetherapeutic effects [51] In the present study the selection ofauricular acupoints was based on the TCM theory and ideasborrowed from modern medicine For example treating the
ldquoheartrdquo can calm the mind while soothing the ldquoliverrdquo couldregulate the flow of qi particularly when insomnia is causedby liver qi stagnation [52] ldquoShenmenrdquo and ldquoocciputrdquo arebelieved to tranquilise the mind and the lsquosubcortexrsquo canharmonise cortex excitement and inhibition [12]
A population-based epidemiological study conducted on5000 subjects in Hong Kong reported that insomnia washighly prevalent amongst Chinese adults and was associatedwith poor mental status and quality of life [53] The present
Evidence-Based Complementary and Alternative Medicine 17
study reported PCS scores of the subjects comparable withthose of Hong Kong people with insomnia (4321 in ourstudy versus 4139 population norm) but stated a slightlyhigherMCS (4668 versus 3636)HRQOL (in PCS andMCS)improved and depression declined over time in subjectstreated with AT Thus quality of life and emotional statusof the subjects may be positively associated with sleepimprovement after the therapy
No specific adverse effectswere observed to arise from thetherapy apart from a small number of reported cases (109)having mild skin irritation on the ears from the adhesivetapes used to hold the experimental tools in place Moreover20 cases (136) reported tenderness on the acupoints andmost of these subjects received MAT According to theauricular diagnosis system the areas of the auricle withheightened tenderness upon touching correspond to specificareas of the body where pathological conditions exist [5455] Applying magnetic pellets may induce physical pressureon the ear acupoints and cause tenderness especially incases with disequilibrium of bodily functions (eg insomnia)corresponding to specific acupoints The tenderness on thereflective acupoints experienced by the subjects may beconsidered part of the treatment process rather than adverseeffects of AT
The high compliance rate (952) and positive impres-sion of the therapy indirectly indicated that blinding wassuccessful because of the successful placebo applicationin the trial Over 75 of the participants expressed thatthey would definitely recommend the therapy to othersThe findings of this trial can provide valuable informationand increase understanding of the therapeutic effect of ATwhether separate or combinedMATandLAT Longer therapyduration may be considered in future trials to determinefurther improvements in the outcome variables The pro-posed treatment approach can be considered as a noninvasivestrategy for managing insomnia amongst the elderly
Although actigraphic monitoring is a reliable objectivemeasure in sleep study changes in different sleep stagescaused by the therapy cannot be ascertained The recruitedelders generally obtained low education levels and had amean age of over 75 and therefore using a sleep log toverify the actigraphic data was not feasible Night-to-nightvariability in the sleeping patterns of subjects may also beaffected by physical psychological andor environmentalfactors Due to the above limitations the actigraphic datamust be interpreted with caution The exact mechanismsremain unknown regarding the interaction of magnetic fieldswith biological tissues which results in functional changesFurther studies from the biomedical perspective are requiredto elucidate the biological pathway of the treatment and effectsuch as to examine the impact of the treatment protocolson the changes in sleep biomarkers when sleep prosperity isachieved
5 Implications
This study provides valuable findings regarding the therapeu-tic effect of different protocols usingMAT LAT or their com-bination In general the AT protocols under testing may be
considered as a noninvasive approach with minimal adverseeffects for managing sleep problems amongst the elderlyThe findings of this study provide important implications toguide future research and apply evidence-based practice inthe community via service provision tomanage this commonproblem
6 Conclusion
The treatment effects of the three protocols were comparablein terms of self-reported sleep conditions HRQOL anddepression status In several parameters such therapeuticeffects may be sustained at six-month follow-up Significantimprovement in the objective sleep parameters could beobserved in subjects who received MAT protocols but notin those who received LAT The combined MAT and LATapproach did not show any advantage over MAT Longertherapeutic course and more frequent administration of LATmay be considered in future trials to achieve the optimaltreatment effect In general the proposed AT protocolswere demonstrated to be a well-received treatment modalitywith minimal adverse effects and effectively improved sleepconditions of the elderly with insomnia

for LAT administration such as daily application adoptedin previous studies [41ndash44] may be considered in futurestudies to enhance the treatment effect and possibly improveits synergistic effect when combined with MAT
Numerous clinical trials reported the use of MAT ondifferent disorders including but not limited to sleep dis-turbances [12 45 46] low back pain [13] constipation [14]and obesity [47] The effectiveness of MAT may relate to the
interaction of magnetic fields with blood flow and calciumchannel proteins in the cell membrane Such interactionsmay elicit functional body changes [16 48 49] MeanwhileLAT is a noninvasive alternative to needle acupuncture [22]and has been adopted to increase pain threshold [50] aswell as relieve musculoskeletal pain [18] and insomnia [17]The laser beam not only irradiates and stimulates acupointsbut also triggers the energy flow (qi) and regulates the

functions of internal organs to achieve a therapeutic effect[22]
According to neuroembryonic theory Dr Paul Nogierviewed the auricle as a homunculus of the human bodyand has a similar shape to an inverted foetus [8] As suchappropriate stimulation of specific ear acupoints can achievetherapeutic effects [51] In the present study the selection ofauricular acupoints was based on the TCM theory and ideasborrowed from modern medicine For example treating the
ldquoheartrdquo can calm the mind while soothing the ldquoliverrdquo couldregulate the flow of qi particularly when insomnia is causedby liver qi stagnation [52] ldquoShenmenrdquo and ldquoocciputrdquo arebelieved to tranquilise the mind and the lsquosubcortexrsquo canharmonise cortex excitement and inhibition [12]
A population-based epidemiological study conducted on5000 subjects in Hong Kong reported that insomnia washighly prevalent amongst Chinese adults and was associatedwith poor mental status and quality of life [53] The present
Evidence-Based Complementary and Alternative Medicine 17
study reported PCS scores of the subjects comparable withthose of Hong Kong people with insomnia (4321 in ourstudy versus 4139 population norm) but stated a slightlyhigherMCS (4668 versus 3636)HRQOL (in PCS andMCS)improved and depression declined over time in subjectstreated with AT Thus quality of life and emotional statusof the subjects may be positively associated with sleepimprovement after the therapy
No specific adverse effectswere observed to arise from thetherapy apart from a small number of reported cases (109)having mild skin irritation on the ears from the adhesivetapes used to hold the experimental tools in place Moreover20 cases (136) reported tenderness on the acupoints andmost of these subjects received MAT According to theauricular diagnosis system the areas of the auricle withheightened tenderness upon touching correspond to specificareas of the body where pathological conditions exist [5455] Applying magnetic pellets may induce physical pressureon the ear acupoints and cause tenderness especially incases with disequilibrium of bodily functions (eg insomnia)corresponding to specific acupoints The tenderness on thereflective acupoints experienced by the subjects may beconsidered part of the treatment process rather than adverseeffects of AT
The high compliance rate (952) and positive impres-sion of the therapy indirectly indicated that blinding wassuccessful because of the successful placebo applicationin the trial Over 75 of the participants expressed thatthey would definitely recommend the therapy to othersThe findings of this trial can provide valuable informationand increase understanding of the therapeutic effect of ATwhether separate or combinedMATandLAT Longer therapyduration may be considered in future trials to determinefurther improvements in the outcome variables The pro-posed treatment approach can be considered as a noninvasivestrategy for managing insomnia amongst the elderly
Although actigraphic monitoring is a reliable objectivemeasure in sleep study changes in different sleep stagescaused by the therapy cannot be ascertained The recruitedelders generally obtained low education levels and had amean age of over 75 and therefore using a sleep log toverify the actigraphic data was not feasible Night-to-nightvariability in the sleeping patterns of subjects may also beaffected by physical psychological andor environmentalfactors Due to the above limitations the actigraphic datamust be interpreted with caution The exact mechanismsremain unknown regarding the interaction of magnetic fieldswith biological tissues which results in functional changesFurther studies from the biomedical perspective are requiredto elucidate the biological pathway of the treatment and effectsuch as to examine the impact of the treatment protocolson the changes in sleep biomarkers when sleep prosperity isachieved
5 Implications
This study provides valuable findings regarding the therapeu-tic effect of different protocols usingMAT LAT or their com-bination In general the AT protocols under testing may be
considered as a noninvasive approach with minimal adverseeffects for managing sleep problems amongst the elderlyThe findings of this study provide important implications toguide future research and apply evidence-based practice inthe community via service provision tomanage this commonproblem
6 Conclusion
The treatment effects of the three protocols were comparablein terms of self-reported sleep conditions HRQOL anddepression status In several parameters such therapeuticeffects may be sustained at six-month follow-up Significantimprovement in the objective sleep parameters could beobserved in subjects who received MAT protocols but notin those who received LAT The combined MAT and LATapproach did not show any advantage over MAT Longertherapeutic course and more frequent administration of LATmay be considered in future trials to achieve the optimaltreatment effect In general the proposed AT protocolswere demonstrated to be a well-received treatment modalitywith minimal adverse effects and effectively improved sleepconditions of the elderly with insomnia

for LAT administration such as daily application adoptedin previous studies [41ndash44] may be considered in futurestudies to enhance the treatment effect and possibly improveits synergistic effect when combined with MAT
Numerous clinical trials reported the use of MAT ondifferent disorders including but not limited to sleep dis-turbances [12 45 46] low back pain [13] constipation [14]and obesity [47] The effectiveness of MAT may relate to the
interaction of magnetic fields with blood flow and calciumchannel proteins in the cell membrane Such interactionsmay elicit functional body changes [16 48 49] MeanwhileLAT is a noninvasive alternative to needle acupuncture [22]and has been adopted to increase pain threshold [50] aswell as relieve musculoskeletal pain [18] and insomnia [17]The laser beam not only irradiates and stimulates acupointsbut also triggers the energy flow (qi) and regulates the

functions of internal organs to achieve a therapeutic effect[22]
According to neuroembryonic theory Dr Paul Nogierviewed the auricle as a homunculus of the human bodyand has a similar shape to an inverted foetus [8] As suchappropriate stimulation of specific ear acupoints can achievetherapeutic effects [51] In the present study the selection ofauricular acupoints was based on the TCM theory and ideasborrowed from modern medicine For example treating the
ldquoheartrdquo can calm the mind while soothing the ldquoliverrdquo couldregulate the flow of qi particularly when insomnia is causedby liver qi stagnation [52] ldquoShenmenrdquo and ldquoocciputrdquo arebelieved to tranquilise the mind and the lsquosubcortexrsquo canharmonise cortex excitement and inhibition [12]
A population-based epidemiological study conducted on5000 subjects in Hong Kong reported that insomnia washighly prevalent amongst Chinese adults and was associatedwith poor mental status and quality of life [53] The present
Evidence-Based Complementary and Alternative Medicine 17
study reported PCS scores of the subjects comparable withthose of Hong Kong people with insomnia (4321 in ourstudy versus 4139 population norm) but stated a slightlyhigherMCS (4668 versus 3636)HRQOL (in PCS andMCS)improved and depression declined over time in subjectstreated with AT Thus quality of life and emotional statusof the subjects may be positively associated with sleepimprovement after the therapy
No specific adverse effectswere observed to arise from thetherapy apart from a small number of reported cases (109)having mild skin irritation on the ears from the adhesivetapes used to hold the experimental tools in place Moreover20 cases (136) reported tenderness on the acupoints andmost of these subjects received MAT According to theauricular diagnosis system the areas of the auricle withheightened tenderness upon touching correspond to specificareas of the body where pathological conditions exist [5455] Applying magnetic pellets may induce physical pressureon the ear acupoints and cause tenderness especially incases with disequilibrium of bodily functions (eg insomnia)corresponding to specific acupoints The tenderness on thereflective acupoints experienced by the subjects may beconsidered part of the treatment process rather than adverseeffects of AT
The high compliance rate (952) and positive impres-sion of the therapy indirectly indicated that blinding wassuccessful because of the successful placebo applicationin the trial Over 75 of the participants expressed thatthey would definitely recommend the therapy to othersThe findings of this trial can provide valuable informationand increase understanding of the therapeutic effect of ATwhether separate or combinedMATandLAT Longer therapyduration may be considered in future trials to determinefurther improvements in the outcome variables The pro-posed treatment approach can be considered as a noninvasivestrategy for managing insomnia amongst the elderly
Although actigraphic monitoring is a reliable objectivemeasure in sleep study changes in different sleep stagescaused by the therapy cannot be ascertained The recruitedelders generally obtained low education levels and had amean age of over 75 and therefore using a sleep log toverify the actigraphic data was not feasible Night-to-nightvariability in the sleeping patterns of subjects may also beaffected by physical psychological andor environmentalfactors Due to the above limitations the actigraphic datamust be interpreted with caution The exact mechanismsremain unknown regarding the interaction of magnetic fieldswith biological tissues which results in functional changesFurther studies from the biomedical perspective are requiredto elucidate the biological pathway of the treatment and effectsuch as to examine the impact of the treatment protocolson the changes in sleep biomarkers when sleep prosperity isachieved
5 Implications
This study provides valuable findings regarding the therapeu-tic effect of different protocols usingMAT LAT or their com-bination In general the AT protocols under testing may be
considered as a noninvasive approach with minimal adverseeffects for managing sleep problems amongst the elderlyThe findings of this study provide important implications toguide future research and apply evidence-based practice inthe community via service provision tomanage this commonproblem
6 Conclusion
The treatment effects of the three protocols were comparablein terms of self-reported sleep conditions HRQOL anddepression status In several parameters such therapeuticeffects may be sustained at six-month follow-up Significantimprovement in the objective sleep parameters could beobserved in subjects who received MAT protocols but notin those who received LAT The combined MAT and LATapproach did not show any advantage over MAT Longertherapeutic course and more frequent administration of LATmay be considered in future trials to achieve the optimaltreatment effect In general the proposed AT protocolswere demonstrated to be a well-received treatment modalitywith minimal adverse effects and effectively improved sleepconditions of the elderly with insomnia

for LAT administration such as daily application adoptedin previous studies [41ndash44] may be considered in futurestudies to enhance the treatment effect and possibly improveits synergistic effect when combined with MAT
Numerous clinical trials reported the use of MAT ondifferent disorders including but not limited to sleep dis-turbances [12 45 46] low back pain [13] constipation [14]and obesity [47] The effectiveness of MAT may relate to the
interaction of magnetic fields with blood flow and calciumchannel proteins in the cell membrane Such interactionsmay elicit functional body changes [16 48 49] MeanwhileLAT is a noninvasive alternative to needle acupuncture [22]and has been adopted to increase pain threshold [50] aswell as relieve musculoskeletal pain [18] and insomnia [17]The laser beam not only irradiates and stimulates acupointsbut also triggers the energy flow (qi) and regulates the

functions of internal organs to achieve a therapeutic effect[22]
According to neuroembryonic theory Dr Paul Nogierviewed the auricle as a homunculus of the human bodyand has a similar shape to an inverted foetus [8] As suchappropriate stimulation of specific ear acupoints can achievetherapeutic effects [51] In the present study the selection ofauricular acupoints was based on the TCM theory and ideasborrowed from modern medicine For example treating the
ldquoheartrdquo can calm the mind while soothing the ldquoliverrdquo couldregulate the flow of qi particularly when insomnia is causedby liver qi stagnation [52] ldquoShenmenrdquo and ldquoocciputrdquo arebelieved to tranquilise the mind and the lsquosubcortexrsquo canharmonise cortex excitement and inhibition [12]
A population-based epidemiological study conducted on5000 subjects in Hong Kong reported that insomnia washighly prevalent amongst Chinese adults and was associatedwith poor mental status and quality of life [53] The present
Evidence-Based Complementary and Alternative Medicine 17
study reported PCS scores of the subjects comparable withthose of Hong Kong people with insomnia (4321 in ourstudy versus 4139 population norm) but stated a slightlyhigherMCS (4668 versus 3636)HRQOL (in PCS andMCS)improved and depression declined over time in subjectstreated with AT Thus quality of life and emotional statusof the subjects may be positively associated with sleepimprovement after the therapy
No specific adverse effectswere observed to arise from thetherapy apart from a small number of reported cases (109)having mild skin irritation on the ears from the adhesivetapes used to hold the experimental tools in place Moreover20 cases (136) reported tenderness on the acupoints andmost of these subjects received MAT According to theauricular diagnosis system the areas of the auricle withheightened tenderness upon touching correspond to specificareas of the body where pathological conditions exist [5455] Applying magnetic pellets may induce physical pressureon the ear acupoints and cause tenderness especially incases with disequilibrium of bodily functions (eg insomnia)corresponding to specific acupoints The tenderness on thereflective acupoints experienced by the subjects may beconsidered part of the treatment process rather than adverseeffects of AT
The high compliance rate (952) and positive impres-sion of the therapy indirectly indicated that blinding wassuccessful because of the successful placebo applicationin the trial Over 75 of the participants expressed thatthey would definitely recommend the therapy to othersThe findings of this trial can provide valuable informationand increase understanding of the therapeutic effect of ATwhether separate or combinedMATandLAT Longer therapyduration may be considered in future trials to determinefurther improvements in the outcome variables The pro-posed treatment approach can be considered as a noninvasivestrategy for managing insomnia amongst the elderly
Although actigraphic monitoring is a reliable objectivemeasure in sleep study changes in different sleep stagescaused by the therapy cannot be ascertained The recruitedelders generally obtained low education levels and had amean age of over 75 and therefore using a sleep log toverify the actigraphic data was not feasible Night-to-nightvariability in the sleeping patterns of subjects may also beaffected by physical psychological andor environmentalfactors Due to the above limitations the actigraphic datamust be interpreted with caution The exact mechanismsremain unknown regarding the interaction of magnetic fieldswith biological tissues which results in functional changesFurther studies from the biomedical perspective are requiredto elucidate the biological pathway of the treatment and effectsuch as to examine the impact of the treatment protocolson the changes in sleep biomarkers when sleep prosperity isachieved
5 Implications
This study provides valuable findings regarding the therapeu-tic effect of different protocols usingMAT LAT or their com-bination In general the AT protocols under testing may be
considered as a noninvasive approach with minimal adverseeffects for managing sleep problems amongst the elderlyThe findings of this study provide important implications toguide future research and apply evidence-based practice inthe community via service provision tomanage this commonproblem
6 Conclusion
The treatment effects of the three protocols were comparablein terms of self-reported sleep conditions HRQOL anddepression status In several parameters such therapeuticeffects may be sustained at six-month follow-up Significantimprovement in the objective sleep parameters could beobserved in subjects who received MAT protocols but notin those who received LAT The combined MAT and LATapproach did not show any advantage over MAT Longertherapeutic course and more frequent administration of LATmay be considered in future trials to achieve the optimaltreatment effect In general the proposed AT protocolswere demonstrated to be a well-received treatment modalitywith minimal adverse effects and effectively improved sleepconditions of the elderly with insomnia

for LAT administration such as daily application adoptedin previous studies [41ndash44] may be considered in futurestudies to enhance the treatment effect and possibly improveits synergistic effect when combined with MAT
Numerous clinical trials reported the use of MAT ondifferent disorders including but not limited to sleep dis-turbances [12 45 46] low back pain [13] constipation [14]and obesity [47] The effectiveness of MAT may relate to the
interaction of magnetic fields with blood flow and calciumchannel proteins in the cell membrane Such interactionsmay elicit functional body changes [16 48 49] MeanwhileLAT is a noninvasive alternative to needle acupuncture [22]and has been adopted to increase pain threshold [50] aswell as relieve musculoskeletal pain [18] and insomnia [17]The laser beam not only irradiates and stimulates acupointsbut also triggers the energy flow (qi) and regulates the

A population-based epidemiological study conducted on5000 subjects in Hong Kong reported that insomnia washighly prevalent amongst Chinese adults and was associatedwith poor mental status and quality of life [53] The present

study reported PCS scores of the subjects comparable withthose of Hong Kong people with insomnia (4321 in ourstudy versus 4139 population norm) but stated a slightlyhigherMCS (4668 versus 3636)HRQOL (in PCS andMCS)improved and depression declined over time in subjectstreated with AT Thus quality of life and emotional statusof the subjects may be positively associated with sleepimprovement after the therapy
No specific adverse effectswere observed to arise from thetherapy apart from a small number of reported cases (109)having mild skin irritation on the ears from the adhesivetapes used to hold the experimental tools in place Moreover20 cases (136) reported tenderness on the acupoints andmost of these subjects received MAT According to theauricular diagnosis system the areas of the auricle withheightened tenderness upon touching correspond to specificareas of the body where pathological conditions exist [5455] Applying magnetic pellets may induce physical pressureon the ear acupoints and cause tenderness especially incases with disequilibrium of bodily functions (eg insomnia)corresponding to specific acupoints The tenderness on thereflective acupoints experienced by the subjects may beconsidered part of the treatment process rather than adverseeffects of AT

Although actigraphic monitoring is a reliable objectivemeasure in sleep study changes in different sleep stagescaused by the therapy cannot be ascertained The recruitedelders generally obtained low education levels and had amean age of over 75 and therefore using a sleep log toverify the actigraphic data was not feasible Night-to-nightvariability in the sleeping patterns of subjects may also beaffected by physical psychological andor environmentalfactors Due to the above limitations the actigraphic datamust be interpreted with caution The exact mechanismsremain unknown regarding the interaction of magnetic fieldswith biological tissues which results in functional changesFurther studies from the biomedical perspective are requiredto elucidate the biological pathway of the treatment and effectsuch as to examine the impact of the treatment protocolson the changes in sleep biomarkers when sleep prosperity isachieved
5 Implications
This study provides valuable findings regarding the therapeu-tic effect of different protocols usingMAT LAT or their com-bination In general the AT protocols under testing may be
considered as a noninvasive approach with minimal adverseeffects for managing sleep problems amongst the elderlyThe findings of this study provide important implications toguide future research and apply evidence-based practice inthe community via service provision tomanage this commonproblem
6 Conclusion
The treatment effects of the three protocols were comparablein terms of self-reported sleep conditions HRQOL anddepression status In several parameters such therapeuticeffects may be sustained at six-month follow-up Significantimprovement in the objective sleep parameters could beobserved in subjects who received MAT protocols but notin those who received LAT The combined MAT and LATapproach did not show any advantage over MAT Longertherapeutic course and more frequent administration of LATmay be considered in future trials to achieve the optimaltreatment effect In general the proposed AT protocolswere demonstrated to be a well-received treatment modalitywith minimal adverse effects and effectively improved sleepconditions of the elderly with insomnia

Numerous clinical trials reported the use of MAT ondifferent disorders including but not limited to sleep dis-turbances [12 45 46] low back pain [13] constipation [14]and obesity [47] The effectiveness of MAT may relate to the
interaction of magnetic fields with blood flow and calciumchannel proteins in the cell membrane Such interactionsmay elicit functional body changes [16 48 49] MeanwhileLAT is a noninvasive alternative to needle acupuncture [22]and has been adopted to increase pain threshold [50] aswell as relieve musculoskeletal pain [18] and insomnia [17]The laser beam not only irradiates and stimulates acupointsbut also triggers the energy flow (qi) and regulates the

functions of internal organs to achieve a therapeutic effect[22]
According to neuroembryonic theory Dr Paul Nogierviewed the auricle as a homunculus of the human bodyand has a similar shape to an inverted foetus [8] As suchappropriate stimulation of specific ear acupoints can achievetherapeutic effects [51] In the present study the selection ofauricular acupoints was based on the TCM theory and ideasborrowed from modern medicine For example treating the
ldquoheartrdquo can calm the mind while soothing the ldquoliverrdquo couldregulate the flow of qi particularly when insomnia is causedby liver qi stagnation [52] ldquoShenmenrdquo and ldquoocciputrdquo arebelieved to tranquilise the mind and the lsquosubcortexrsquo canharmonise cortex excitement and inhibition [12]
A population-based epidemiological study conducted on5000 subjects in Hong Kong reported that insomnia washighly prevalent amongst Chinese adults and was associatedwith poor mental status and quality of life [53] The present
Evidence-Based Complementary and Alternative Medicine 17
study reported PCS scores of the subjects comparable withthose of Hong Kong people with insomnia (4321 in ourstudy versus 4139 population norm) but stated a slightlyhigherMCS (4668 versus 3636)HRQOL (in PCS andMCS)improved and depression declined over time in subjectstreated with AT Thus quality of life and emotional statusof the subjects may be positively associated with sleepimprovement after the therapy
No specific adverse effectswere observed to arise from thetherapy apart from a small number of reported cases (109)having mild skin irritation on the ears from the adhesivetapes used to hold the experimental tools in place Moreover20 cases (136) reported tenderness on the acupoints andmost of these subjects received MAT According to theauricular diagnosis system the areas of the auricle withheightened tenderness upon touching correspond to specificareas of the body where pathological conditions exist [5455] Applying magnetic pellets may induce physical pressureon the ear acupoints and cause tenderness especially incases with disequilibrium of bodily functions (eg insomnia)corresponding to specific acupoints The tenderness on thereflective acupoints experienced by the subjects may beconsidered part of the treatment process rather than adverseeffects of AT
The high compliance rate (952) and positive impres-sion of the therapy indirectly indicated that blinding wassuccessful because of the successful placebo applicationin the trial Over 75 of the participants expressed thatthey would definitely recommend the therapy to othersThe findings of this trial can provide valuable informationand increase understanding of the therapeutic effect of ATwhether separate or combinedMATandLAT Longer therapyduration may be considered in future trials to determinefurther improvements in the outcome variables The pro-posed treatment approach can be considered as a noninvasivestrategy for managing insomnia amongst the elderly
Although actigraphic monitoring is a reliable objectivemeasure in sleep study changes in different sleep stagescaused by the therapy cannot be ascertained The recruitedelders generally obtained low education levels and had amean age of over 75 and therefore using a sleep log toverify the actigraphic data was not feasible Night-to-nightvariability in the sleeping patterns of subjects may also beaffected by physical psychological andor environmentalfactors Due to the above limitations the actigraphic datamust be interpreted with caution The exact mechanismsremain unknown regarding the interaction of magnetic fieldswith biological tissues which results in functional changesFurther studies from the biomedical perspective are requiredto elucidate the biological pathway of the treatment and effectsuch as to examine the impact of the treatment protocolson the changes in sleep biomarkers when sleep prosperity isachieved
5 Implications
This study provides valuable findings regarding the therapeu-tic effect of different protocols usingMAT LAT or their com-bination In general the AT protocols under testing may be
considered as a noninvasive approach with minimal adverseeffects for managing sleep problems amongst the elderlyThe findings of this study provide important implications toguide future research and apply evidence-based practice inthe community via service provision tomanage this commonproblem
6 Conclusion
The treatment effects of the three protocols were comparablein terms of self-reported sleep conditions HRQOL anddepression status In several parameters such therapeuticeffects may be sustained at six-month follow-up Significantimprovement in the objective sleep parameters could beobserved in subjects who received MAT protocols but notin those who received LAT The combined MAT and LATapproach did not show any advantage over MAT Longertherapeutic course and more frequent administration of LATmay be considered in future trials to achieve the optimaltreatment effect In general the proposed AT protocolswere demonstrated to be a well-received treatment modalitywith minimal adverse effects and effectively improved sleepconditions of the elderly with insomnia

Although actigraphic monitoring is a reliable objectivemeasure in sleep study changes in different sleep stagescaused by the therapy cannot be ascertained The recruitedelders generally obtained low education levels and had amean age of over 75 and therefore using a sleep log toverify the actigraphic data was not feasible Night-to-nightvariability in the sleeping patterns of subjects may also beaffected by physical psychological andor environmentalfactors Due to the above limitations the actigraphic datamust be interpreted with caution The exact mechanismsremain unknown regarding the interaction of magnetic fieldswith biological tissues which results in functional changesFurther studies from the biomedical perspective are requiredto elucidate the biological pathway of the treatment and effectsuch as to examine the impact of the treatment protocolson the changes in sleep biomarkers when sleep prosperity isachieved
5 Implications
This study provides valuable findings regarding the therapeu-tic effect of different protocols usingMAT LAT or their com-bination In general the AT protocols under testing may be
considered as a noninvasive approach with minimal adverseeffects for managing sleep problems amongst the elderlyThe findings of this study provide important implications toguide future research and apply evidence-based practice inthe community via service provision tomanage this commonproblem
6 Conclusion
The treatment effects of the three protocols were comparablein terms of self-reported sleep conditions HRQOL anddepression status In several parameters such therapeuticeffects may be sustained at six-month follow-up Significantimprovement in the objective sleep parameters could beobserved in subjects who received MAT protocols but notin those who received LAT The combined MAT and LATapproach did not show any advantage over MAT Longertherapeutic course and more frequent administration of LATmay be considered in future trials to achieve the optimaltreatment effect In general the proposed AT protocolswere demonstrated to be a well-received treatment modalitywith minimal adverse effects and effectively improved sleepconditions of the elderly with insomnia
