I WARNINGS

1 - Counter-indications

2 - Safety measures

• Cardiac stimulator (pacemaker).• Pregnancy (do not use in abdominal

region).• Troubles Serious arterial circulation

disorders in lower limbs.• Abdominal or inguinal hernia.

Important!

• Never use Compex 3 on patients whohave sensitivity problems or who areunable to let you know if they feel anydiscomfort, however slight.

• Read this manual and theaccompanying Practical Guide carefully.

Important points to take intoaccount when using Compex 3 andthe m system

• Do not use the Compex 3 stimulator orthe m-4 system in water or humidenvironments (saunas, hydrotherapypools, etc.).

• Do not use the stimulator or m-4system in oxygen-rich environments.

• Never carry out the first 5 minutes ofany stimulation session on a patient whois standing. Make sure they are seatedor lying down. In rare instances, people ofa nervous disposition may experience avasovagal reaction. This is apsychological response triggered by fearof the procedure and the shock of seeingone of their muscles contractinvoluntarily. A vasovagal reactioncauses a patient’s heart to slow downand blood pressure to drop, which canmake them feel weak and faint. Shouldthis happen, simply interrupt the sessionand help the patient to lie down with theirlegs raised until the feeling disappears(5 to 10 minutes).

• Contractions should always be isometric.Never allow active muscle contractionsduring a stimulation session.

• Do not use the stimulator or m-4system on a patient who is connected toa high-frequency surgical instrument asthis could cause skin irritation or burnsunder the electrodes.

• Do not use the stimulator or m-4system within 1 metre of short wave ormicrowave devices as this could alter thecurrents generated by the stimulator.

• Do not use the stimulator or m-4system in areas where unprotecteddevices are used to emitelectromagnetic radiation. Portablecommunications equipment caninterfere with electrical medicalequipment.

• Only use stimulation cables supplied byCompex.

• Always switch off the stimulator beforedisconnecting any stimulation cablesduring a session.

• Never connect the stimulation cables toan external power source due to risk ofelectric shock.

• Only use rechargeable battery unitssupplied by Compex.

• Never recharge the stimulator withoutfirst disconnecting all stimulation cables.

• Do not recharge the battery with acharger other than that supplied byCompex.

• Do use the Compex 3 stimulator, dockingstation, or charger if any of the elementsare damaged (case, cables, etc.) or if thebattery compartment is open. There is arisk of electric shock.

• Unplug the charger immediately if yourCompex 3 emits a continuous beepingsound or if you notice any abnormal heat,smells, or smoke from either thecharger or the stimulator.

• Never recharge the battery in a confinedspace (carrying case, etc.) as this couldcause a fire or electric shock.

• Keep Compex 3 and its accessories outof the reach of children.

• Keep the stimulator, batterycompartment, docking station, andcharger free of foreign matter (soil,water, metal, etc.)

• Sudden temperature changes can causecondensation to build up inside thestimulator. To prevent this, allow it toreach ambient temperature before use.

• Do not use your Compex 3 while drivingor operating machinery.

• Do not use the stimulator at altitudes ofover 3,000 metres.

Never use the electrodes orthe motor point pen:

• In the vicinity of the head.

• Counter-laterally, i.e. do not use twopoles connected to the same channel onopposite sides of the body.

• On or near skin lesions of any kind(wounds, swelling, burns, irritation,eczema, etc.).

Precautions when using them-4 system

• To access Compex 3’s m functions, makesure that the stimulation cable fitted withthe m-4 is connected before youturn on the stimulator.

• Do not connect the m-4 cable whilethe Compex 3 is connected.

• Do not disconnect the m-4 cablewhile the sensor is being used.

• The m-4 system may not workcorrectly if restrained or subject topressure in any way.

Precautions when using theelectrodes and the motor point pen

• Only use electrodes and pens supplied byCompex. Other electrodes and pens mayhave electrical properties that areincompatible with the Compex 3stimulator.

• Always turn off the stimulator beforemoving or removing any electrodes duringa session.

• Do not place the electrodes or the pen inwater.

• Do not apply solvents of any kind to theelectrodes or pen.

• For optimal results, wash and clean theskin of any oil and dry it before attachingthe electrodes.

• Attach the electrodes in a such a way thattheir entire surface is in contact with theskin.

• For hygiene reasons, each patient musthave his own set of electrodes. Never usethe same electrodes on different patients.

• Never use a set of adhesive electrodes formore than 15 sessions as their stickingpower deteriorates with time and optimalcontact is very important for both usercomfort and treatment efficacy.

• Some people with very sensitive skin mayexperience redness under the electrodesafter a session. This redness is generallyharmless and normally disappears within10 to 20 minutes. Never start anotherstimulation session in the same area,however, if the redness is still visible.

• Clean and disinfect the tip of the motorpoint pen that comes in contact with theskin before each use.

III USAGE GUIDELINES

The usage guidelines described in thissection are valid only for Compex 3’sneurostimulation programmes. Pleaseconsult separate guidelines for theDenervated, Iontophoresis, and Oedema

programmes. In all cases, read theinformation and recommendations in thePractical Guide carefully.

1 - Placement of electrodes(neurostimulation programmes)

For optimal results, use the electrodepositions recommended by Compex. Forthe placement of electrodes, refer to theelectrode placement booklet.

Each stimulation cable has two poles:

• positive pole (+) = red connection• negative pole (-) = black connection

A different electrode must be connected toeach pole.

NOTE: When working with largeelectrodes, there are cases where just 1of the 2 connections are used. This isperfectly normal.

Depending on the characteristics of thecurrent, efficacy can be optimized incertain programmes by placing theelectrodes connected to the positive pole(red connection) “strategically”.

When working with a muscle stimulationprogramme (programme involving musclecontractions), it is important to place thepositive electrode on the motor point of themuscle.

It is crucial to choose the right sizeelectrodes (large or small) and correctlyposition these on the muscle group youwant to stimulate to ensure the efficacy ofthe treatment. To do this, always use thesizes and positions shown in thepictograms unless otherwise required bymedical needs. Where necessary, look forthe best possible position by slowly movingthe positive electrode over the muscle untilyou find the point that will produce the bestcontraction or the most comfort for thepatient.

These recommended positions are alsothe optimal positions for the m-4system, and as such should be followedclosely.

Compex disclaims all responsibilityfor consequences arising from electrodesplaced in other positions.

2 - Body position

4 - Level progression

3 - Adjusting stimulation energies(neurostimulation programmes)

Refer to the pictograms and pictures in theelectrode placement booklet to determinethe stimulation position for your patientdepending on the placement of theelectrodes and the chosen program..

This position will vary depending on theposition of the electrodes, the muscle groupyou wish to stimulate, and the programmeyou are using.When working with programmes involvingmuscle contractions (prolonged, or tetanic,contractions), always make the muscle work

isometrically as this will prevent cramps andserious muscle soreness after the session.For example, when stimulating thequadriceps, place the patient in a seatedposition with his ankles strapped in place toprevent him from extending his knees. Forprogrammes that do not involve musclecontractions (Analgesic programmes, forexample), make sure that the patient is ascomfortable as possible.

The number of fibres recruited in astimulated muscle depends on thestimulation energies used. It is thereforeextremely important to use maximumstimulation energies where possible in orderto recruit the maximum number of fibres. Ifthe stimulation energy is too low, too fewfibres will be obliged to work and theimprovement in muscle quality will benegligible.

The more fibres that are recruited, thegreater the improvement that will be seen.For example, if only 10% of the fibres in amuscle are stimulated, only this 10% willimprove. The improvement will obviously bemuch greater if 60%, 70%, or even 80% ofthe fibres are stimulated. It is crucialtherefore to work with maximum stimulationenergy levels, i.e. the maximum levels that a

patient can tolerate. It takes at least3 sessions to reach this maximum energylevel. The first few sessions serve tointroduce progressive increments instimulation energy (and muscle contraction)levels and to help the patient to become usedto the method.After an initial warm-up period, which shouldproduce very clear muscle twitches, increasethe stimulation energies gradually,contraction by contraction, for the durationof the session. Also seek to progressivelyincrease energy levels from session tosession.

Generally speaking, it is not advisable to tryand reach maximum stimulation levels tooquickly. The different levels in eachstimulation programme are designed toreeducate the muscle gradually.We recommend you prioritize thestimulation energies at each level to recruitas many fibres as possible before movingon to the next level.

Ideally, therefore, you should start at level 1,maintain this level for an entire stimulationcycle, and only move up to the next levelwhen you start a new cycle.For maintenance purposes, it is a good ideato hold one session per week with theenergy level you used in the previous cycle.

5 - Alternation of stimulation/active reeducation sessions

1 - Practical guidelines for using

the m system

Stimulation sessions are mostly used aspart of a reeducation programme.If you wish to combine a reeducationsession involving voluntary muscle trainingwith a muscle stimulation session, wegenerally recommend you schedule the

reeducation session first. This ensuresthat the patient does not have to work ontired muscle fibres.

Compex’s m technology providespractitioners with specific information ondifferent muscles and allows them toadapt each stimulation session to theneeds of their patients.

The corresponding data is transferredautomatically from the sensor to thestimulator!

IV m TECHNOLOGY

To access the m functions, makesure that the stimulation cable fitted withthe m-4 is connected to thestimulator before this is turned on.

Do not connect the m-4 cable if thestimulator is already on.The m-4 system may not workproperly if restrained or subject topressure in any way.

The m-4 must be connected to anadhesive electrode at all times during astimulation session.

m-4 ____________________

This is a small sensor that links thestimulator to the electrodes. It performs akey function in that it measures certainphysiological characteristics of the muscleto be stimulated and transfers this data tothe stimulator, which, in turn, analyses thedata and adapts its parametersaccordingly. This tailoring of eachprogramme to the changing condition ofthe muscle clearly enhances both patientcomfort and therapeutic efficacy.

m-3 ______________________

Just before beginning a stimulation session,the m-3 analyses the excitability of themuscle to be stimulated. The m-3determines the chronaxy of the muscle inapproximately 12 seconds and sends thisdata to the stimulator so that it can adaptthe pulse width (duration) accordingly.Adapting the pulse width to the chronaxy ofthe muscle to be stimulated allows thesame muscle response to be achieved withless energy.

NOTE: The m-3 function is enabled onlywhen a cable fitted with the m-4system is connected to the stimulator.

As many as 4 different chronaxymeasurements – corresponding to4 different muscle groups – can be takenper session. The number ofmeasurements depends on how manysensors are connected to the stimulator.

17

COMPEX

3UserMan

ual

Each channel that is connected to astandard cable receives the same data asa channel connected to a m-4 cable(see below).

Before a programme is executed, thesensor scans the muscle briefly. Duringthis time, a horizontal bar will move up anddown the figure on the left of the screen.

It is essential that the patient remainscompletely still and relaxed while thesemeasurements are being taken. Them-4 system is very sensitive and theslightest contraction or movement couldinterfere with its results.

Note that certain people might feel anunpleasant tingling sensation during thetest.

Once the test is complete, a symbol willappear on the screen indicating thatthe programme can be started.

m-1 _____________________

m-1 is a work mode in which thepatient triggers an electrically inducedstimulation by voluntarily contracting oneof his muscles. The stimulation contractionis therefore controlled by the patient.

For a patient to fully benefitfrom the m-1 training mode, hismuscles must be well developed.Insufficiently developed muscles may, insomecase, prevent the triggering of theelectrically induced contraction.

Programmes run in m-1 mode offer anumber of distinct benefits:

• They require the active participation ofpatients and encourage them to becomefully involved in their treatment.

• They allow patients to control theircontractions, allowing them to feel moreat ease with the system.

• They optimize performance by combiningvoluntary and electrical stimulationexercises, which results in a moreintensive recruitment of muscle fibres.

• They help to retone the body andfacilitate motor reeducation in patientswith neuromuscular disorders.

• They integrate the stimulation ofstabilising muscles into a broaderfunctional exercise plan.

The m-1 mode is only available forcertain programmes.

Programmes run in m-1 mode arealways preceded by a m-3 test.

The m-1 mode is enabled only duringwork sequences (not during warm-up andrelaxation sequences).The first muscle contraction in the worksequence is triggered automatically.This is followed by an active rest phaseconsisting of a series of muscle twitches.Le déclenchement volontaire d’une nouvellecontraction n’est possible qu’après un tempsde repos minimum, qui varie selon leprogramme. A new contraction can only betriggered after a minimum rest time, whichvaries from programme to programme. Thestimulator emits a signal to notify the patientwhen he can trigger another contraction.

This signal can take different forms:

• A series of increasingly fast short beeps:voluntary contraction possible.

• A continuous beep: ideal moment forvoluntary contraction.

• A series of increasingly slow beeps:voluntary contraction still possible andwork rate still satisfactory.

• If no voluntary contractions are detectedwithin a certain time (this varies fromprogramme to programme), the stimulatorwill automatically enter Standby mode.

18COMPEX

3UserMan

ual

NOTE: The m-4 system needs to recordthe muscle twitches in the active rest phasein order to offer optimal results.If the twitches are not sufficiently intenseduring this phase, the stimulator will emit aseries of beeps and a sign will appearon the screen.Note that these muscle twitches will onlyoccur if the muscles are sufficientlyrelaxed. Patients should therefore beencouraged to adopt a position in whichthey will be as relaxed as possible at theend of each contraction phase.

In contrast to CommonTreatment programmes in which thestimulator adjusts the stimulation energiesduring the rest phase, these energiesoften need to be increased manually whenin m-1 mode.

m-5 ______________________

The m-5 function can be used toconsiderably reduce the number ofunwanted muscular contractions,enhancing both user comfort andtreatment efficacy.

It is available only for the TENS, ModulatedTENS, Epicondylitis and Arthralgiaprogrammes.When enabled, the m-5 functioncontrols stimulation energies by keepingthem at an effective level and reducing thenumber of unwanted contractions.

It works by performing a series of shortmeasurement tests (lasting 2 to 3seconds) at regular intervals throughoutthe entire programme.

A test is automatically launched wheneverthe stimulation energies are increased.The subject must remain perfectly stillduring the test to ensure optimal results.

Depending on the results, the stimulatormay automatically reduce the stimulationenergies slightly.

NOTE: It is important to ensure thatpatients adopt the most comfortableposition possible during stimulation,remain still, and do not contract any of themuscles in the stimulation area.

m-6 _____________________

The m-6 function is used inprogrammes which depend on thetriggering of vigorous muscle twitches toindicate the optimal stimulation energyrange.

It is therefore only available inprogrammes that use low stimulationfrequencies (less than 10 Hz).

When the m-6 function is enabled, thestimulator will check whether you areworking in the optimal energy range. If thelevel is too low, it will prompt you toincrease the level by displaying a series of

signs on the screen.

Once the stimulator has detected the idealenergy range, a square bracket will appearto the right of the bar graph correspondingto the stimulation channel the m-4 isconnected to. The figures enclosed by thisbracket indicate the range you must workin in order to achieve optimal results.

If you set the energy level below this range,the stimulator will prompt you to increaseit by flashing a series of signs on thescreen.

A) Connecting the cablesThe stimulator cables plug into the 4sockets on the base of the device.All 4 cables can be connected simultaneously.Both the sockets and the cables arecolour-coded to simplify use and facilitateidentification of the different channels:

blue=channel 1 green = channel 2yellow = channel 3 red = channel 4

The kit includes four snap-connectorcables and four 2,1 mm pin-connectorcables.

NOTE: The pin-connector cables aredesigned for use only with Denervated,Iontophoresis and Hyperhidrosisprogrammes.

To connect a snap-connector cable to anelectrode, simply insert the snap end of thecable into the electrode eyelet and twist ita quarter turn.

In addition to these standard cables,Compex 3 comes with 2 special cablesfitted with the m-4 system.These cables can be connected to any ofthe 4 sockets for the stimulation channels,on the base of the stimulator. Just like thestandard cables, they must also beconnected to 2 electrodes.

B) Connecting the motorpoint pen

Never use the motor point pen for anypurposes other than locating the motorpoint of the muscle. Follow the instructionsin this manual. Clean and disinfect the tip ofthe motor point pen that comes in contactwith the skin before each use.

Apply a small amount of Compex gel to theskin when looking for the motor point toenhance patient comfort.

All Compex 3 stimulators are supplied witha motor point pen designed to help you tofind the exact location of the motor point ofthe muscle group(s) you wish to stimulate.Refer to the picture below to see how toconnect the pen.

Connect the tip of the motor point pen tothe positive connector (red). The othersnap connector (black) must be connectedto a negative electrode already on themuscle to be stimulated.

VII COMPEX 3 SOFTWARE

1 - Scope

Your Compex 3 stimulator comes with aCompex 3 software programme that willhelp you to manage your patients.

The programme offers 3 main featuresthat will allow you to:• Create a list of patients under treatment• Create a patient history• Create personalised programmes

A) Creating a patient list

Compex 3 software allows you to create alist of patients on your computer andassign each patient a list of treatments tobe performed. You can then transfer thisinformation to the Compex 3 stimulator,where you will have direct access topriority treatments and be able to ensurethat the treatments performed, by you or acolleague, are consistent with yourtherapeutic choices.The option also allows you to initiate anelectrotherapy session without having tofirst consult the patient’s file on yourcomputer.

B) Creating a patient history

Any treatments performed on a patientare recorded by the stimulator and canthen be transferred to the patient’s historyfile stored on the computer.In addition to creating a patient history, youcan also consult statistics on stimulatoruse and check which treatments havebeen used most.

C) Creating a personalisedprogramme

The software also allows you to design yourown treatment programmes, which canthen be transferred to the stimulator andused like any other programmes.

NOTE: Compex 3 software is optional. It isnot a requirement for using the Compex 3stimulator.

C) Synchronising the stimulator

When the stimulator is connected to yourcomputer, either via the docking station ordirectly, via a USB cable, you can transferdata from the computer to the stimulatorand vice versa.

The software retrieves the data stored inthe stimulator since the lastsynchronisation and updates the data onthe computer by recording the content ofthe stimulator’s history file.It then updates the patient list on thestimulator so that it coincides with the liston the computer.

Click the SYNCHRO button to bring up thefollowing screen:

1

This screen allows you to lock thestimulator (anti-theft system).Compex 3 software allows you to block thestimulator after a fixed number of days. Todo this, check the corresponding box andenter the number of days you wish it tooperate for.When the lock option is checked, thestimulator will only function for the numberof days you have specified. The days arecounted from the moment ofsynchronisation. After this time, the userwill not be able to execute any treatmentsand the stimulator will only function againonce it has been resynchronised. Torelease the lock function, the stimulatormust be synchronised with the samecomputer that was used to lock it.

OK: Click this to start the synchronisationprocess.

Annuler: Click this to cancel thesynchronisation process.

A message will appear on the screenindicating the successful completion of theprocess.

NOTE: When working in multi-plan mode(see D) Tools, Plans settings), you will beasked to choose which plan you wish tosynchronise.

When should you synchronisea stimulator ?Synchronisation is necessary whenever youwish to modify the list of patients in thestimulator, when you wish to update yourpatients’ treatment histories, or when youwish to transfer a new set of personalisedprogrammes to the stimulator.

When should you synchronise severalstimulators at the same time?When you are using several Compex 3stimulators, we recommend that yousynchronise these regularly in order tokeep the patients’ treatment histories up todate. When synchronising severalstimulators at a time, first synchroniseeach stimulator to retrieve the informationstored in their memories, and then repeatthe process to ensure that they are allupdated with the same data.

Synchronising with another computerIf you attempt to synchronise yourstimulator with a computer other than theone you normally use, the following screenwill appear.

You can choose to abort or continue theprocess. If you continue, however, bear inmind that you will lose any data stored inthe stimulator’s history file since the lastsynchronisation. You will also be updatingthe stimulator with the data contained inthe software on the computer you areusing.

NOTE: Compex 3 software is only compati-ble with the Compex 3 stimulator. It cannotbe used to synchronise other stimulators.
