Yoga and Science in Pain Care - The Role of Yoga in Evidence-Informed Pain Care
By: Linnea Thacker, Physiotherapy Resident, MSc(PT), DMA

Estimated reading time: 6 minutes

This is the 9th blog post in a series based on the Yoga and Science in Pain Care Book Club, a 15-part course based on the book by the same title, by Neil Pearson, Shelly Prosko, and Marlysa Sullivan. You can find the blog corresponding to Chapter 1 here.

Introduction - Yoga and Science in Pain Care Chapter 2

There’s a hip, new tool being used in pain care these days. Generally speaking, this new tool seems to be at least as effective as our standard workhorses, at least as safe (Tick et al., 2018), and often better adhered to (Saper et al., 2017).

Oh, and by “new,” I mean it’s thousands of years old. Give or take.

As you may have guessed from the blog title, we’re talking about yoga.

We have entered a time when an increasing number of people are practicing yoga and healthcare providers are increasingly referring patients to yoga for various health conditions. And for good reason. 

There’s a growing body of evidence supporting the use of yoga in healthcare, especially in pain care. You can delve into this topic in great detail in the Embodia course Yoga and Science in Pain Care (based on the book of the same title). 

For those interested in exploring the research around yoga in pain care, the second chapter, “Current Research in Yoga and Pain” by Steffany Moonaz does a great job of synthesizing the current state of research on using yoga for various pain-related health conditions.

Chapter 2: Current Research in Yoga and Pain


You may be feeling a little skeptical about how yoga fits into a healthcare provider’s evidence-informed practice, and you wouldn’t be alone. As we tackle this topic together, a useful first step would be to explore what exactly we mean when we say “evidence-informed practice”.


A quick history of evidence-informed practice (EIP)

When we look at the history of evidence-informed practice, we are naturally drawn back to the concept of evidence-based medicine (EBM), a practice with philosophical origins that reaches at least as far back as mid-19th century Paris. In their 1996 article “Evidence-Based Medicine: What it is and What it Isn’t”, Sackett et al. describe EBM as follows: 

 Definition of evidence-based medicine by Sackett et al.


While including the best available evidence in healthcare decisions sounds like a step in the right direction, EBM has not been without its critics.

One concern voiced by critics relates to the type of evidence that is prioritized (namely randomized controlled trials), as EBM tends to place a heavy emphasis on quantitative research over qualitative research that may explore patients’ experiences. Even before the term was coined, some medical professionals expressed concern over the direction that medicine was headed, by seemingly replacing individualized, patient-led care with scientific reductionism.

One such voice was that of Paul Tournier, a Swiss general practitioner (1898-1986). Here’s one such account of Tournier’s views:


Paul Tournier's concern about the medicine's direction


Anyone who read the first blog in this series will recognize that Tournier was on to something. As the quote from a medical resident in Rice et al.’s 2018 article states: “within the [medical] curriculum…we don’t talk about how to actually care for someone without trying to cure them” (p. 777).

Well done, Tournier. You called it. Unfortunately.


An alternative approach

In response to these criticisms, the concept of evidence-informed practice (EIP) has emerged. This approach decentres scientific evidence as the primary factor on which healthcare decisions should be made. Instead, this approach is typically seen as having three equally-weighted components:

  1. Clinician expertise
  2. Best available evidence
  3. Patient preferences, rights, and values

EIP lends itself more intuitively to person-centred care and tends to be the preferred term used by clinicians today to denote a practice “informed by rather than one based on the E of EBM and where the person or the patient returns to the very center of the clinical encounter” (Miles and Loughlin, 2011, p. 534).


So how does yoga philosophy fit into Evidence-Informed Practice (EIP)?

Having explored some of the philosophical bases of EIP, we may wonder how a practice like yoga, with its rich philosophical history, fits into this contemporary (largely Western) approach. In an article from 2017 entitled “Understanding yoga’s roots in evidence-informed practice,” Marlysa Sullivan et al. explore Samkhya philosophy (a philosophy that has played a foundational role in the development of yoga, yoga therapy, and Ayurveda), and how it relates to EIP.

While the details of these overlapping philosophies can be explored in greater depth in the article, Sullivan et al. make a strong argument that incorporating yoga within an evidence-informed practice is by no means antithetical to yoga philosophy, but rather can align quite nicely with it.

Specifically, the article explores the three components of discriminative knowledge within the Samkhya framework (perception, inference, and reliable or valid testimony), and elucidates their relationships to the three components of EIP. The authors even present a graphic to illustrate the overlapping qualities of the three elements of Samkhya with the three elements of EIP:

This brief article is well worth the read if the topic is of interest!


Yoga and the evidence

So now that we’ve explored EIP and how it relates to yoga philosophy, do we even have evidence to support the use of yoga in pain care?

The short answer is YES.

While there have been decidedly fewer high-quality research studies investigating the use of yoga for pain care compared to other, more conventional interventions, the studies that have been conducted overwhelmingly support yoga as a safe option that is at least as effective as currently-used interventions.

At least as effective? But we want more effective!

Sure, that would be wonderful, but let’s keep in mind how research works. In order to convincingly demonstrate that an intervention is more effective than no intervention, we need to be able to show a clear difference in outcomes in the two (or more) groups that can’t be realistically attributed to chance. When the intervention is effective, it’s not too hard to show that, oh look, almost everyone who got the treatment ended up doing much better than almost everyone who got no treatment. Fancy that. (Okay, that’s a bit of a lie, it is hard to show that, but less hard than what comes next.)

Now, when we are looking to compare one intervention against an already-proven-to-be-effective intervention, the differences in outcomes between the two treatment groups are going to be much smaller. It then becomes harder to convincingly say that those differences can’t be attributed to chance. It certainly can be done, but it generally needs many more participants to be able to reveal the trend in a compelling way.

And the reality is, we just don’t have a lot of studies on yoga interventions with massive sample sizes, yet.


Other challenges

It’s also worth noting that there are many different components to yoga, types of yoga, and ways to deliver yoga. Yoga as an intervention could include all or any one of:

  • Breathing practices
  • Movement practices, which could be geared towards:
    • Strength
    • Stability
    • Mobility
    • Relaxation/restoration
    • Regulation (nervous systems, emotions, energetic states, etc.)
    • Awareness (interoceptive, proprioceptive, etc.)
    • Balance
    • Neuromotor timing
    • Coordination, agility, dexterity, etc.
  • Chanting practices
  • Meditative practices
  • Lifestyle practices
  • Integrating yoga principles 

With such diversity in what could be included in a yoga intervention, clear and transparent reporting becomes critical. Unfortunately, yoga interventions have not always been clearly reported in the research, making it more difficult to apply interventions clinically or to summarize findings across studies.

The good news is that steps are being taken to improve the quality of reporting in yoga research, notably through the 2021 publication of the CLARIFY guidelines.

These guidelines comprise a 21-item checklist considered the minimum details necessary for high-quality reporting of yoga research. (And in case you think the lead author’s name is familiar, you would be right. Steffany Moonaz is both the lead author of the CLARIFY guidelines and the author of Chapter 2 of Yoga and Science in Pain Care.)

Yoga and Science in Pain Care Book


So what do we know about yoga in pain care?

If you’re looking for an efficient summary of the state of research on yoga for pain care without doing a full literature review yourself, Steffany’s chapter in 'Yoga and Science in Pain Care' is a great place to start.

If listening to someone is more your style, she covers all the highlights in the Yoga and Science in Pain Care Embodia course:

Yoga and Science in Pain Care Book Club Series


In both forms, she goes through the evidence supporting the use of yoga for neck pain, low back pain, arthritis, neurological pain (including fibromyalgia, headaches, multiple sclerosis, and chronic fatigue syndrome), and abdominal pain (including irritable bowel syndrome and endometriosis).

Given the challenges associated with studying the effects of yoga in pain care, we already have an impressive body of evidence supporting yoga’s inclusion in healthcare, and that supporting evidence seems only to be mounting.

Something for us to consider as we take stock of our current pain care tools and consider what other options exist that are effective, accessible, safe, and feasible for our patients that may also be of interest, value, and empowering to them.
