    #64: Is measuring strength useful? With Tim Cook

    Jared is joined by Tim Cook who is Senior Lecturer in Physiotherapy at the University of Chichester, Advanced Physiotherapy Practitioner in the NHS, and doctoral researcher to discuss their new paper with Prof. Jeremy Lewis in the Journal of Manual & Manipulative Therapy: "Rethinking strength testing in rotator cuff-related shoulder pain: a clinical tradition that lacks muscle." Tim explains what pushed him to question routine strength testing in busy clinical practice, despite guidelines recommending it, and the pair dig into whether weakness is a cause of shoulder pain, a consequence of it, or something else altogether. They look at what subacromial anaesthetic injection studies reveal about pain versus true force output, and Tim reframes the classic "weak and painful shoulder" as the "flexible but painful shoulder," drawing parallels to other oversimplified clinical narratives like posture and core stability. They also make the case for when strength testing can still earn its keep; patient engagement, expectation violation, building confidence, and sporting or return-to-performance populations such as ACL limb symmetry index, before turning to Goodhart's Law and the risk of chasing the test rather than the outcome, and why isolated isometric tests may not translate to real-world, endurance-based shoulder tasks. Tim closes out with an update on his PhD: a reliability RCT on strength and pain-free assessment currently in press, and an upcoming scoping review on the proposed mechanisms of exercise for RCRSP.

    #59: Exercise, sets, reps and the pharmacology problem

    Is more always better? Is there a dose response effect of exercise for musculoskeletal pain? Should exercise be just like a medication, where the dose has to be sufficient in order for it to elicit a therapeutic effect?  These are the questions we contend with on this episode of The Shoulder Physio Podcast.  Key resources Lawford BJ, Hinman RS, Spiers L, Kimp AJ, Dell'Isola A, Harmer AR, Van der Esch M, Hall M, Bennell KL.

    # 58: Most rotator cuff tears don't hurt

    The FIMAGE study scanned both shoulders of 602 adults from the general population using high-resolution 3-Tesla MRI. Only 7 had a structurally normal rotator cuff. In this episode, I walk through what the study found, why 78% of full-thickness tears were in people with no shoulder pain, and what happens to the diagnostic value of a scan when the finding it detects is near-universal. I challenge the assumption that prevalence equals normality, explore why the word "tear" imports a trauma narrative into what is usually a degenerative process, and make the case that imaging findings deserve a smaller seat at the clinical reasoning table than we've historically given them.
