What's old school?

We were asked a question about why we thought that speaking in pathoanatomical and biomechanical terms was a bit old school. With this being both a topical and important conversation, we wanted to share our response as a mini-blog. :) 

Our position that pathoanatomical and biomechanical reasoning is a bit old school is based on the evidence used to test these models and their limited ability to guide treatment interventions that improve clinical outcomes. For example, in the lumbar spine, we are able to conclusively identify the specific tissue or pathology at fault about 10 to 15% of the time and typically these conditions would include radiculopathies, inflammatory, conditions, fractures and cancers. I would argue that this is when pathology is important – in situations where we can identify and screen for those 10% of cases where patients have a medical pathology that requires further medical intervention. Equally important to physiotherapy practice is the ability to understand when the evidence identifies that our clinical tests and subjective questioning has limited utility in identifying a pathology and/or treatment. Sometimes using tests and historical questions that have limited utility can lead our reasoning astray and serve as red herring. Our traditional assessment that includes palpating for specific mobility deficits that guide our identification of tissue lesion or limited movement has limited support in the research1. Even if these findings were well supported in the literature, would it matter? There is evidence that demonstrates a limited ability to focus our treatment to a specific segmental level2. Furthermore, it would appear that from both an outcome and a neurophysiological perspective, specificity of manual therapy is both not required and unobtainable3,4. 

So where does this leave us? I don’t think we need to throw the baby out with the bathwater and doesn’t mean that our treatment interventions, at a glance, look all that different. What has changed is the reasoning behind choosing to implement manual therapy and, more importantly, the language used with patients regarding their diagnosis and why manual therapy is being used. Idealistically, I would use a system where we could reliably identify a specific pathology that leads to a specific treatment intervention that improves clinical outcomes but at this point it would appear that we are far from this and that the use of a model like this may give the clinician a false sense of security in their diagnosis. There is a risk that the use of a pathoanatomical model in the cases of mechanical low back pain leads to clinicians to provide patients with labels and language that create negative health beliefs and perpetuate fear and disability.  “Words That Harm and Words That Heal”5discusses the impact of clinician language on patients pain experience while this article by Lo et al discusses the changes in Australian Aboriginals beliefs secondary to exposure to Western based care of low back pain6. What has also changed is that our model for the assessment and treatment of patients has increased to include the biopsychosocial realm and its importance in the patients pain experience and prognosis. Things such as fear avoidance beliefs and pain catastrophizing have repeatedly been identified as impacting patients outcomes7,8and there is research to identify that we can include interventions such as education and graded exposure9,10.

With respect to the comment “Isn't this what the rehabilitation sciences were originally based on - empirical observations and anatomical understanding leading to testing and the 'evidence base'”, you are right that this is the starting point for research. We live in a dynamic time with medical literature being published at an extraordinary rate. Research will continue to answer questions and often for each question answered, two new ones will arise. Failure to keep up with these changes from a clinical perspective can lead to suboptimal treatment and from a professional perspective the risk of becoming obsolete. 

Finally, as was brought up, the “Art” of physiotherapy is fascinating. There is growing evidence that this art is likely not based on our use of a specific technique but rather the way with which we interact with our patients11, both clinician and patient expectations of treatment12,13 and an understanding of these factors and their implementation into clinical practice could serve to help improve patient outcomes.

We would very much be interested in people's thoughts regarding our response and would encourage you to discuss them with us on one of our social media platforms. We’d be particularly interested in any evidence you have that supports a pathoanatomical diagnostic model that demonstrates its use leads the clinician to a specific treatment that provides superior outcomes. We are always interested in thoughtful discussion!

RIP Canadian DPT

You were an incredible program. Fun, inspiring, relevant, and evidence based. You advanced the hearts and minds of so many Canadian Physios. We’ll miss you.

The Canadian tDPT program started out as a dream. One of best PT education outfits in the world was bringing programming to Canada! It was going to be awesome. It was awesome... It is dead.

This is the story of the birth and death of a great opportunity for Canadian Physios.

It started with Evidence In Motion (EIM), a beast of an education group, which is led by some of the foremost researchers/thought leaders in the PT world. They’ve built up first rate programs (DPT, Residency, and Fellowship) in the US taught by the likes of John Childs, Tim Flynn, Julie Whitman, Rob Wainner, Josh Cleland, Steven George, and many more. All inspiring, all passionate, all expert clinicians and researchers.

Their Mission is to elevate the physical therapy profession and the role of physical therapists in health care delivery.

Their Promise is to develop and facilitate ideas to provide physical therapists with the necessary training and tools to become leaders in Evidence-based practice.

In 2016, EIM partnered with Jack Miller and Rob Werstine of Key Clinical Skills (KCS). They together undertook a new foray into Canada with KCS obtaining a license to deliver the Transitional Doctorate of Physical Therapy program in the great white north. How exciting this was for those of us who’d travelled to the US for the program and knew what a gem it was.

KCS and AMP are old friends, and KCS asked AMP if we would like to help out with teaching. We were pumped.  

So started a new adventure. We taught, we learned, we had a great ol’ time. Students loved it. We saw an exponential rise of evidence based practice in our network of colleagues. All of a sudden conversations were based on rehabilitation sciences and evidence, and not on dated biomechanical/pathoanatomical theory. How refreshing.

It didn’t however sit well with everyone. There were some detractors. All good, change is bumpy.

Also, the program name was rather unfortunate. EIM’s program was called a transitional ‘Doctorate’ which is, we came to learn, not okay. EIM’s program wasn’t registered as a degree program in Canada; whereas in the US, APTA supports the tDPT program to upgrade clinicians’ skills, and EIMs Doctorate of Physiotherapy, Residency Program, and Fellowship program are all registered and licensed.

We agree with the Ministry's decision to stop a program that has 'Doctorate' in the title when it hasn't received the appropriate accreditation. I want to make that clear. This protected term misleads students taking the program and the public when they evaluate Physiotherapists' training. The mistake was keeping the same name that the program had in the states.

So it all came tumbling down based on this name issue. Hopefully EIM will continue to provide programs (with different names) in Canada.

In any event, Canadian PTs should seek access to EIM's content. It’s relevant, up to date, evidence rich, has a heavy focus on clinical reasoning, and best of all the programs develop reflective practitioners who know how to consume evidence and think maturely about it.

It’s a gloomy day today, but the sun will rise again. It’s AMP’s mission to bring quality continuing education to Canadian PTs. We’re committed to bring in world class educators like Lorimer Moseley, Tim Gabbett, Adam Meakins, Jeff Moore, Cory Blickenstaff, the NOI group, and more. These weekend courses are certainly stimulating, but we know that to meaningfully change practice habits a prolonged course of education and learning is needed. To that end, we're working on it.
