The Irish Pain Research Network (IPRN)

Aim

• To bring together all active pain researchers on the island of Ireland (North and South) for the purposes of sharing research results and ideas and facilitating cross-institutional collaboration in the area of pain research

Page 2: The Irish Pain Research Network (IPRN)irishpainsociety.ie/.../IPRNDataBlitz-Symposium2015.pdfUCD School of Public Health, Physiotherapy and Population Science UCD Health Science Centre

Origins of IPRN

• Discussions in late 2014 between NUI Galway pain researchers (Prof. David Finn and Dr. Brian McGuire) and UCD researchers (Dr. Brona Fullen, Dr. Catherine Doody and Dr. Catherine Blake)

• Idea advanced with the IPS Committee

• IPRN is a Special Interest Group (SIG) of the IPS

• Launched formally at the 15th Annual Scientific Meeting of the Irish Pain Society, 26th Sept 2015

Page 3: The Irish Pain Research Network (IPRN)irishpainsociety.ie/.../IPRNDataBlitz-Symposium2015.pdfUCD School of Public Health, Physiotherapy and Population Science UCD Health Science Centre

Anticipated benefits of IPRN• Facilitate greater collaboration• Forum for presenting research results, sharing ideas,

networking• Multidisciplinary

– Neuroscience, Psychology, Physiotherapy, Nursing, Pain Medicine etc

• Easier access to expertise and methodologies– Training, lab visits, student exchanges– Website: repository of expertise

• Opportunities for junior researchers to present and network

• IPRN members better positioned to apply successfully for research grants (HRB, SFI etc)– Particularly multi-institute grant applications

• Raise the profile of pain and pain research in Ireland

Page 4: The Irish Pain Research Network (IPRN)irishpainsociety.ie/.../IPRNDataBlitz-Symposium2015.pdfUCD School of Public Health, Physiotherapy and Population Science UCD Health Science Centre

Page 9: The Irish Pain Research Network (IPRN)irishpainsociety.ie/.../IPRNDataBlitz-Symposium2015.pdfUCD School of Public Health, Physiotherapy and Population Science UCD Health Science Centre

Key Research Findings

• The endocannabinoid system mediates fear-induced analgesia (Finn et al., 2004, Eur J Neurosci; Butler et al., 2008, Pain; Ford et al., 2010, Pain; Olango et al., 2013, Br J Pharmacol)

• Dysfunction of the endocannabinoid system in PAG/RVM circuitry may contribute to hyperalgesia associated with negative affect (Rea et al., 2014, Pain)

• Developed a novel rat model of postoperative pain associated with inguinal hernia repair (Bree et al., 2015, J Pain)

• Monoaminergic and neuroimmune alterations underpin altered nociceptive processing in animal models of depression (Burke et al., 2015, Behav Brain Res; 2014, Brain Behav Immun, 2013, Genes Brain Behav, 2013, J Pain)

• The endocannabinoid system modulates neuroinflammatoryprocesses (Roche et al., 2006 J Neuroimmunol; Kerr et al., 2012, Neuroscience; 2013, Br J Pharmacol; Henry et al., 2014, J Neuroimmunol)

Pain in childhood : parental and family factors

catastrophicthoughts

distress

various samples & methodologies :

• self-report (Caes et al., 2011;2012, Pain)

• psychophysiological

assessment (Caes et al., 2012, Pain)

• observational assessment (Caes et al., 2014, Clin J Pain, J Ped Psychol)

children are highly dependent on their parents

parental responses critically important!

protective (e.g. comfort, reassure) : increase in child pain

coping–promoting (e.g. distracting, coping instructions) : decrease in child pain

lack of research on

• moderating influence of family functioning on parental behaviour

• bidirectional, mutual influence between parents and children from infancy

through adolescence

(e.g. changes in and transfer of responsibilities for pain management)

PAIN CLASSIFICATION

(Dr C Doody)

Alterations in pain processing in people with chronic MSK pain

states are indicative of pain sensitization

The presence of pain sensitization may be linked to symptom

severity

PAIN MANAGEMENT &

REHABILITATION

(Dr B Fullen)

CBT-PMP – 6/12 - sig. CSC in patient outcome measures

Startback – Stratification demonstrated superior outcomes in high

risk patients, & equally good for medium & low risk groups –

effective model of care

PAIN MEASUREMENT &

OUTCOME ASSESSMENT

(Dr C. Blake)

People with knee OA show signs of neural mechanosensitivity

Less efficient exercise induced hypoalgesia in knee OA patients,

particularly with high pressure pain sensitivity

EVIDENCE BASED MEDICINE

(Prof. L. O’Connor)

NP post SCI- pooled prevalence is 54%; paraplegic 46%,

tetraplegic 52%

Health literacy – low scores associated with less engagement with

health services, more co-morbidities

Key research questions

• Does providing a biopsychosocial, individualised treatment for LBP improve clinical outcomes? And if so, is it worth the extra costs?

• Musculoskeletal pain: is it what you do or the way that you do it? A study of therapeutic alliance in physiotherapy

• What factors are changed after an exercise programme for Achilles tendinopathy? – is it pain, tendon structure, muscle strength, fear, confidence?

• What is the role of spinal posture in shoulder pain?

• The Working with Arthritis program: Can an

occupational therapy-led vocational intervention support

people with musculoskeletal disorders to remain in,

or return to, work?

Page 45: The Irish Pain Research Network (IPRN)irishpainsociety.ie/.../IPRNDataBlitz-Symposium2015.pdfUCD School of Public Health, Physiotherapy and Population Science UCD Health Science Centre

Recent research findings

• Group exercise for MSK pain is more effective than individual exercise (sys review)

• A mix of interpersonal, clinical and organisational factors influence the patient-therapist interaction (systematic review)

• Major predictors of injury in professional dancers are systemic factors (poor sleep and general health complaints), rather than physical or biomechanical factors (prospective study)

Improved Quality of Life following Capsaicin 8% treatment

•Capsaicin 8% is a beneficial addition to the medication armamentarium for the treatment of Neuropathic Pain (NP). •With 62.5% of patients experiencing at least a 30% reduction in pain at rest and 54% of patients on movement at 3 months, treatment with Capsaicin 8% should be considered to patients suffering NP as a first line treatment.•The results demonstrated that treatment of NP with Capsaicin 8% can be managed in a nurse led clinic, positive results are achieved and patients are happy with the treatment received.

Aims1. Profile levels of work related disability/instability in patients

in paid employment referred with RMSKP in Ireland;

2. Specify the content and delivery of an early integrated care intervention to improve work retention/participation, decrease distress, improve functional status, and increase health related quality of life among RMSKP patients;

3. Feasibility test, pilot and evaluate the intervention in terms of efficacy and economic impact.

Page 54: The Irish Pain Research Network (IPRN)irishpainsociety.ie/.../IPRNDataBlitz-Symposium2015.pdfUCD School of Public Health, Physiotherapy and Population Science UCD Health Science Centre

Design• Phase 1:

– (a) Systematic review to collate the evidence on interventions to prevent work disability/instability in RMSKP

– (b) Quantitative study to document levels of work related disability/instability in patients referred for RMSKP in Ireland.

• Phase 2: Needs analysis of specific patient requirements to inform the intervention content.

• Phase 3:– (a) Specification of the content, components, mode and timing of the

intervention;– (b) Comprehensive feasibility and pilot testing with evaluation of

patient outcomes and economic impact.

specific core set of patient requirements that will comprise the early integrated care intervention;

identify key barriers and facilitators of work participation, associated support needs, and service expectations and priorities amongst patients with RMSKP

examine potential challenges in intervention delivery

identify optimal timing for delivery of the intervention

Perceptions of fatigue, pain, sleep dysfunction and barriers to exercise in people with FMS: A focus group study

Russell D, Álvarez Gallardo IC, Wilson I, Hughes CM, Davison GW, Sañudo B, McVeigh JG

Fatigue / sleeplessness / pain / cognitive dysfunction: “I think the fatigue is worse than the pain, the pain you know what to do and what not to do…”

Exercise is a major challenge for patients: Household chores, ADLs exercise in themselves

“exercise to me is a scary word … “

“my exercise consists of getting out of bed…”

Lack of understanding:‘Doctors need to realize, we wouldn’t chose to live like this…”

Loss of self / role / function: “Life has been stolen.”

“Sometimes you just don’t go out at all, the person you were before this illness has totally changed.”
