Why Our Chronic Pain Treatment Strategy Works
Updated: Jan 27, 2022
Pain Research Studies
Research over the last 10-15 years has significantly changed how health practitioners view chronic pain. Mechanisms have been discovered to validate symptoms previously seen as purely psychological. These mechanisms help explain why pain lingers for months, even years, despite previously injured tissues having had enough time to heal.
In one study they reviewed mechanisms for chronic pain following post-surgical pain and highlighted 5 main pathways to chronic pain as shown below. Keep in mind that this post is not meant to paint a complete picture of chronic pain, but to briefly illustrate some of the recent developments in the field. The hope is that this information gets the ball rolling for those of us with chronic pain that have had limited success with previous treatments.

How Chronic Pain Works
It’s likely that if you suffer from chronic pain, some, or even all of these points on the diagram are involved to some level. They represent a hypersensitive nervous system that responds based on previous injuries. Although your initial pain response was very useful in protecting you from potential tissue injury, it is now limiting and no longer reflects injury. This means that in chronic pain, pain does not equal harm. This is actually true for pain in general but requires a more detailed approach to explain. To make sense of this think of phantom limb pain in amputees – there are no tissues left to generate the pain response from, but the hypersensitive nervous system still manages to send the signal.
A Multidisciplinary Approach
With this change in how chronic pain works, a large shift in what we should do about it has also come about. Multiple studies are finding a multidisciplinary approach to be most appropriate in handling chronic pain.
A new guideline published by the Canadian Medical Association journal recommends non-opioid treatments as front-line care for chronic non-cancer pain. For those currently taking opioids who are having difficulty tapering, they recommend a multidisciplinary approach.
“Possibilities include, but are not limited to, a primary care physician, a nurse, a pharmacist, a physical therapist, a chiropractor, a kinesiologist…”
Busse, et al., 2017. Canadian Medical Association Journal: Guideline for opioid therapy and chronic noncancer pain
In focusing on opioid risk, these guidelines not only represent a step in the right direction in tackling the opioid epidemic in Canada, but also highlight the accumulation of evidence supporting conservative therapies such as chiropractic, and physical therapy in managing chronic pain.
More specifically, treatment strategies rooted in patient education and regaining trust in your body’s durability have shown the greatest long-term results for chronic pain. O'Sullivan's group termed this approach “cognitive functional therapy”, which is a handle that means considering pain generation as multi-dimensional, and focuses on both mind and body when treating chronic pain.
The cognitive component specifically aims to break down fears, beliefs, and expectations that may be associated with pain through education on chronic pain mechanisms and myths.
The functional component finds painful activities or movements and desensitizes them over time by teaching non-threatening ways to perform them over time. Here are the results of this approach in one of their studies, as compared to conventional treatments for chronic low back pain.
decrease in pain intensity over twice as much as a comparison, with results lasting at final follow up of 12 months
decrease in disability measures over twice as much as a comparison, also lasting up to 12 months
overall lasting decrease in fear-avoidance behaviors
O’Sullivan, 2013. European Journal of Pain: Efficacy of classification-based cognitive functional therapy in patients with non-specific chronic low back pain: a randomized controlled trial.
O’Sullivan’s study is on chronic low back pain specifically but is one of many showing better results with this model of thinking compared to conventional treatments.
In the clinic, we embrace this evidence-based model by ruling out any tissue damage, then continuing treatment with an emphasis on education,
breaking down threatening movements, and pacing strategies so you can get long-term results.
Along the way we provide passive care such as adjustments and soft tissue therapy to help you get there while focusing on decreasing practitioner dependence.
Keep in mind that this approach only applies to those suffering from chronic musculoskeletal pain who have been cleared from tissue damage by a health professional such as chiropractor, or physical therapist. There are certainly situations of chronic pain where repetitive tissue trauma is a primary contributor. In these situations we would suggest a biomechanical approach aimed at facilitating recovery.
If you suffer from chronic pain, visit your local chiropractor or physical therapist and hold them accountable to an evidence-based plan that focuses on your goals and independence to get back to the things you love.
