The Problem..
• Chronic Musculoskeletal Pain▪ One of the most common reasons to visit the GP
▪ Untreated => depression, poor quality of life and loss of independence
• Often begins with an acute nociceptive event▪ Majority of episodes are short and self limiting
• Why do some persist?▪ Causes are multi-factorial
▪ An individuals genetics and neurophysiology have a role
![Page 4: Dr Chris Hoffman Mr Chris Gregg Dr Julie Zarifeh](https://reader030.fdocuments.us/reader030/viewer/2022012723/61b4d5b65ac91a024d613394/html5/thumbnails/4.jpg)
Most patients with pain see their health care professional because:
• they are in pain and they want it to stop.
• they will be worried and they need reassurance.
• they want information about the source of the pain and the prognosis.
![Page 5: Dr Chris Hoffman Mr Chris Gregg Dr Julie Zarifeh](https://reader030.fdocuments.us/reader030/viewer/2022012723/61b4d5b65ac91a024d613394/html5/thumbnails/5.jpg)
RCT - UCLA Back Pain Study
• GP vs Chiropractor treatment
• Clinically equal outcome
• But more satisfied with Chiro
• 2 reasons
- Receipt of self care advice
- Explanation of treatment

BioPsychoSocial Model
• Hurt vs Harm
• Illness vs Disease
• Activity vs Rest

Classification of Chronic Pain
Can be based on major pain features or body region
• Musculoskeletal (mechanical)
• Myofascial
• Neuropathic
• Fibromyalgia
• Chronic headache syndromes
• BMJ Best Practice – Chronic Pain

Acute vs Chronic Pain
![Page 10: Dr Chris Hoffman Mr Chris Gregg Dr Julie Zarifeh](https://reader030.fdocuments.us/reader030/viewer/2022012723/61b4d5b65ac91a024d613394/html5/thumbnails/10.jpg)
Chronic Pain Disorders

New Term = “Nociplastic” pain
• International Association for the Study of Pain
• Pain arises from altered nociception
• Can follow on from acute nociceptive pain
• Impact on patient
• Impaired physical function / Disability
• Person / Social setting / Work setting
![Page 14: Dr Chris Hoffman Mr Chris Gregg Dr Julie Zarifeh](https://reader030.fdocuments.us/reader030/viewer/2022012723/61b4d5b65ac91a024d613394/html5/thumbnails/14.jpg)
Pain or Disability?
• Pain is not disability.
• The focus is resolving the disability not resolving the pain.
• Disability resolution needs both behavior and cognitive therapies.
• Determine the underlying mechanical triggers
![Page 15: Dr Chris Hoffman Mr Chris Gregg Dr Julie Zarifeh](https://reader030.fdocuments.us/reader030/viewer/2022012723/61b4d5b65ac91a024d613394/html5/thumbnails/15.jpg)
Regions affected
• Back pain (53%)
• Headache (48% - ?cervical / muscular)
• Joint pain (46%)
• When re-evaluated in 12 months 46% persist
![Page 16: Dr Chris Hoffman Mr Chris Gregg Dr Julie Zarifeh](https://reader030.fdocuments.us/reader030/viewer/2022012723/61b4d5b65ac91a024d613394/html5/thumbnails/16.jpg)
Focus on 4 common areas
• Cervical Spine pain
• Lumbar Back pain
• Shoulder joint pain or instability
• Knee pain
![Page 17: Dr Chris Hoffman Mr Chris Gregg Dr Julie Zarifeh](https://reader030.fdocuments.us/reader030/viewer/2022012723/61b4d5b65ac91a024d613394/html5/thumbnails/17.jpg)
Trauma?
• Often a triggering event
• Particularly in NZ = ACC
• Needs to be a history of application of external force
• Problem is age related degenerative changes
![Page 18: Dr Chris Hoffman Mr Chris Gregg Dr Julie Zarifeh](https://reader030.fdocuments.us/reader030/viewer/2022012723/61b4d5b65ac91a024d613394/html5/thumbnails/18.jpg)
Degenerative?
• Age-related change
• Normal range of aging
• Life-style / genetics
![Page 19: Dr Chris Hoffman Mr Chris Gregg Dr Julie Zarifeh](https://reader030.fdocuments.us/reader030/viewer/2022012723/61b4d5b65ac91a024d613394/html5/thumbnails/19.jpg)

Knee Pain and Degree of OA
• High Pain / Low Pain Pain Stimulated =
• Mild OA / Severe OA Measure Sensitization
• High Pain / Mild OA = Central sensitization
• High Pain / Severe OA = ?inflammatory
• Low Pain / Mild OA = Appropriate response
• Low Pain / Severe OA = Resilient ?how
• Finan P et al Arthritis Rheum 2013 Feb 65(2) 10

Why am I still in pain?
• Resolution of the nociceptive pain • “Mal-adaptation” to ongoing pain • Nociplastic pain becomes the problem
• Analogy – Priming of immune response▪ Stimulus has triggered response▪ System changes – now responds to normal stimulus▪ Treatment? – “re-train the guard dog”
• Ensure no further mechanical stimulus• Normalize Activity /Exercise • Focus on reducing disability

Dear doctor,
I saw your patient in pain clinic…. He has chronic pain….Please reduce his medication.I have not made further follow-up plans.
Yours Sincerely
![Page 35: Dr Chris Hoffman Mr Chris Gregg Dr Julie Zarifeh](https://reader030.fdocuments.us/reader030/viewer/2022012723/61b4d5b65ac91a024d613394/html5/thumbnails/35.jpg)

What do they do in pain clinic?
![Page 37: Dr Chris Hoffman Mr Chris Gregg Dr Julie Zarifeh](https://reader030.fdocuments.us/reader030/viewer/2022012723/61b4d5b65ac91a024d613394/html5/thumbnails/37.jpg)
New Zealand Health Survey 2011/12, 16% of adults reported chronic pain (defined as pain that occurs every day, for
at least 6 months)
That is about 600,000 adults
![Page 38: Dr Chris Hoffman Mr Chris Gregg Dr Julie Zarifeh](https://reader030.fdocuments.us/reader030/viewer/2022012723/61b4d5b65ac91a024d613394/html5/thumbnails/38.jpg)
1 year
12 months
52 weeks
365 days
8760 hours
People with long term health conditions spend about 3 hours a year with their health professional
The remaining 8757 hours they are on their own
![Page 39: Dr Chris Hoffman Mr Chris Gregg Dr Julie Zarifeh](https://reader030.fdocuments.us/reader030/viewer/2022012723/61b4d5b65ac91a024d613394/html5/thumbnails/39.jpg)
600,000 people X 8757h = a lot of hours alone
![Page 40: Dr Chris Hoffman Mr Chris Gregg Dr Julie Zarifeh](https://reader030.fdocuments.us/reader030/viewer/2022012723/61b4d5b65ac91a024d613394/html5/thumbnails/40.jpg)
Solution = patient takes care of themselves
![Page 41: Dr Chris Hoffman Mr Chris Gregg Dr Julie Zarifeh](https://reader030.fdocuments.us/reader030/viewer/2022012723/61b4d5b65ac91a024d613394/html5/thumbnails/41.jpg)
Pain Self Management
![Page 42: Dr Chris Hoffman Mr Chris Gregg Dr Julie Zarifeh](https://reader030.fdocuments.us/reader030/viewer/2022012723/61b4d5b65ac91a024d613394/html5/thumbnails/42.jpg)
What is pain self management?
• What it is NOT▪ It is not medication▪ It is not physiotherapy▪ It is not psychological
support▪ It is not a surgical procedure▪ It is not something done to
the patient▪ It is not coping – your
patients are already doing it
![Page 43: Dr Chris Hoffman Mr Chris Gregg Dr Julie Zarifeh](https://reader030.fdocuments.us/reader030/viewer/2022012723/61b4d5b65ac91a024d613394/html5/thumbnails/43.jpg)
Manage pain by choosing
ACTIVE
and sustainable strategies to
target the areas affected by pain.
What is pain self management?
![Page 44: Dr Chris Hoffman Mr Chris Gregg Dr Julie Zarifeh](https://reader030.fdocuments.us/reader030/viewer/2022012723/61b4d5b65ac91a024d613394/html5/thumbnails/44.jpg)
Active pain management skills
1. Good sleep hygiene to improve sleep
2. Limiting rest
3. Establish regular physical activity
![Page 45: Dr Chris Hoffman Mr Chris Gregg Dr Julie Zarifeh](https://reader030.fdocuments.us/reader030/viewer/2022012723/61b4d5b65ac91a024d613394/html5/thumbnails/45.jpg)
Educational component
• Education around why pain persists
• Collaborative goal setting
• Coping skill acquisition▪ Physical – activity pacing, graded
exposure▪ Psychological – relaxation, attention
regulation, communication, problem solving, cognitive restructuring
![Page 46: Dr Chris Hoffman Mr Chris Gregg Dr Julie Zarifeh](https://reader030.fdocuments.us/reader030/viewer/2022012723/61b4d5b65ac91a024d613394/html5/thumbnails/46.jpg)
Learning to self manageIt is like driving a car
Where does the instructor sit?Where does the learner sit?
![Page 47: Dr Chris Hoffman Mr Chris Gregg Dr Julie Zarifeh](https://reader030.fdocuments.us/reader030/viewer/2022012723/61b4d5b65ac91a024d613394/html5/thumbnails/47.jpg)
That’s so hard!Are you sure there are no medication
or injection to try?
![Page 48: Dr Chris Hoffman Mr Chris Gregg Dr Julie Zarifeh](https://reader030.fdocuments.us/reader030/viewer/2022012723/61b4d5b65ac91a024d613394/html5/thumbnails/48.jpg)
High dose opioids – No high quality evidence Methadone – No conclusion can be madeTapentadol – further studies neededPregabalin – note effective in chronic conditions which nerve damage is not the prime source of painGabapentin and pregabalin in preventing migraine attacks – not effectiveAntidepressives for NSLBP – No evidenceMuscle relaxants for NSLBP – short term relief, adverse effects require cautionNSAIDS for NSLBP – Short term relief, effect size is smallNSAIDS for low back pain and sciatica – not more effective than placebo in reducing sciatica. Overall improvement but results should be used interpreted with cautionProlotherapy for chronic low back pain – conflicting evidenceBotox for lower back pain and sciatica – low or very low qualityInjection therapy for subacute and chronic low back pain – insufficient evidence to support use of injection therapyNSAIDs – low quality evidence in osteoarthritis. No evidence for other chronic painful condition.Paracetamol – No evidence to support or refute provide pain reliefVitamin D – No consistent pattern Vit D better than placebo. More research is needed.Gabapentin for fibromyalgia – No good evidencePregabalin for fibromyalgia –Provided pain relief 10% more than placeboMilnacipran for fibromyalgia – Provided pain relief to 10% more than placebo, it will not work for most people.Duloxetine for fibromyalgia – low quality evidence duloxetine is effectiveBotox for myofascial pain – inconclusive evidencePregabalin for chronic prostatitis. Chronic pelvic pain – one RCT showing that pregabalin does not improve CP/CPPSCannabinoids – FPM PM10
Pharmacology often fails

Ideal situation for pain managementPatient:- Early chronic pain- Job attached- Surgically/ medically cleared- Motivated or willing to look at a different approach
Treatment team:- Multidisciplinary team- Rehabilitation approach- Strong emphasis on self management not passive therapy- Flexible and accommodating
![Page 53: Dr Chris Hoffman Mr Chris Gregg Dr Julie Zarifeh](https://reader030.fdocuments.us/reader030/viewer/2022012723/61b4d5b65ac91a024d613394/html5/thumbnails/53.jpg)
What do they do in pain clinic?
Comprehensive assessment- Medical clearance for rehabilitation- Medication review and optimisation- Organise appropriate on referral, imaging or intervention - Assess impact of pain: biopsychosocial approach- Assess readiness to change- Assess barriers to change
Provide pain management education and experiential guidance.
![Page 54: Dr Chris Hoffman Mr Chris Gregg Dr Julie Zarifeh](https://reader030.fdocuments.us/reader030/viewer/2022012723/61b4d5b65ac91a024d613394/html5/thumbnails/54.jpg)
If patients are not ready?
• Patience and compassion• Upskill your and patients knowledge around neurophysiology of
persistent pain• Encourage exploration of pain management as an alternative• Reinforce current evidence• Explore and identify area of life impacted by pain• Adhoc supports – psychology only, physiotherapy only,
medication trial• Harm minimisation
