The Shoulder Physio Podcast: Recent Episodes
Jared Powell
The Shoulder Physio Podcast is a podcast dedicated to exploring meaningful topics in musculoskeletal health care.
What exactly is a placebo effect? When you try and pin it down, it's confusing. Technically, it's something inert that produces an effect...how can there be an effect without a mechanism? Prof. Steve Kamper is here to help bring clarity to the issue.

Science is ubiquitous. But what is it? Everyone talks about science and the significance of being scientific but nailing down just what this means for clinical practice in physical therapy is somewhat elusive. To clear all this up, I’m joined by the Science Pt, Erik Meira. Erik is a sharp and eloquent communicator about science and its application to physical therapy. You don’t want to miss this one.

Exercise for knee osteoarthritis is a non-negotiable and effective intervention, right? Well, maybe it’s not so clear. Evidence seems to be dropping every month challenging the privileged position that exercise occupies for managing knee osteoarthritis. Front and centre is the infamous DICSO trial, published in 2022, and this study will serve as the foundation for this debate. The debate features Marius Henriksen and Christian Barton and these two men engage in polite yet passionate intellectual battle with the aim of figuring out just what role exercise plays for managing people with knee osteoarthritis.

Osteoarthritis (OA) is a leading cause of pain and disability. OA is also seems to be associated with several myths and misconceptions about how it is caused and how it might be managed. To cut through some of this mythology, I invited Professor David Hunter on the show for a 'no holds barred' conversation. David is the number 1 ranked expert in the world on OA, so it should come as no surprise he is a wealth of knowledge and a clear communicator on the complexities of osteoarthritis. I hope you enjoy.

In this podcast, I discuss the scapula with Filip Struyf, PhD. Filip is a former guest on the show (episode 2) and I've pulled him back on the podcast to tackle the hard problems as they relate to the scapula. Specifically, in this episode we consider the question: "If we identify a scapula dyskinesis in our physical examination, should we attempt to rectify it?".

Feeling stiff is a familiar feeling for all of us. But does feeling stiff mean our joints are actually stiff? Or is there more to it. Tasha Stanton PhD is a clinical neuroscientist who has performed research directly addressing this question. This is a fascinating conversation and I hope you enjoy.

I am joined by Connor Gleadhill to discuss causal inference. Connor is a PhD candidate exploring causal inference and is someone who speaks fluently about complex topics (must be the smooth Irish accent!). Causal inference is basically the pursuit of estimating how and why things happen. How do we determine causation - strictly through the randomised controlled trial or can we use observational evidence too? Can causal inference help us navigate a chaotic world?

The biopsychosocial model is ubiquitous in modern health care but what is it at its core? Is it accurately described and used in research and clinical practice? To help make headway into these questions and more, I'm joined by Ben Cormack. Ben is a MSK therapist from England who has developed a special interest in the philosophy and implementation of the biopsychosocial in MSK health care.

Cognitive biases are as much of a problem as they are fundamental to the human condition. They exist, but can we mitigate them? What common cognitive biases afflict health care? Jarod and Jared shoot the s**t around these interesting questions.

In this episode I am joined by Scot Morrison to discuss the envelope of function model, as proposed by Scott Dye in the 1990s. The envelope of function has gained increasing acceptance over the past decade and I thought a deep dive into this concept was needed to highlight the potential pro's and con's of implementing this into clinical practice.

In this episode I am joined by Greg Lehman and Andrew Lock to discuss lifting technique/mechanics and it's relevance to low back pain/injury. The research in this area is inconclusive so I've brought Greg and Andrew on to clarify some contentious topics.

Pain is common and vital for survival. Chronic pain, though, is less vital and can significantly impact on the quality of life. Bronnie Thompson, PhD, believes it is possible to lead a fulfilled life in the presence of persistent pain. This is a must-watch/listen for all clinicians and even those who experience pain themselves. The paper we reference is listed below:

I had a conversation with the wonderful team at E3 rehab about the fuzzy and entrenched diagnostic label that is shoulder impingement. Over the 1 hour episode we discuss the history, inaccuracies and potential negative consequences of the term. This is a must listen if you've wondered why this term is controversial. Please refer to my accompanying Instagram post from February 27 for references mentioned in the episode.

In this episode I talk to Abby Tabor, PhD, on the interesting topic of predictive processing and how it may relate to understanding and explaining pain.
Abby is a physiotherapist who has gone on to become a prolific researcher in the field of active inference/predictive processing. Abby is a product of Lorimer Moseley's lab in Adelaide, Australia and is a clear communicator on this complex topic.

Greg is a renowned physiotherapist and chiropractor and is well known for reconciling biomechanics with pain science, which, coincidentally, is the name of his course! We talk about pain, the nuances of it, and the potential simplicity in helping people with pain minimise suffering and disability.

The topic of manual therapy and its role in physical therapy always elicits differences of opinion. In this episode, Adam Meakins and Chad Cook tackle the hard questions and attempt to clarify what manual therapy does (and doesn't) and where it fits into contemporary physical therapy care (if anywhere!).

In this episode, I discuss the scapula with Filip Struyf, PhD. We attempt to answer the measurement error question and how this influences everything thereafter! After all, if we can't accurately measure something it becomes impossible to prove the validity and lacks any utility in clinical practice.
