Proximal Hamstring Tendinopathy - the forgotten tendinopathy

This week I talk about a feasibility cohort study which sought to determine whether a larger cohort study addressing this question would be feasible. Listen to hear some interesting preliminary findings.  Merza, E.Y., Pearson, S.J., Mallows, A.J. and Malliaras, P., 2023.

We have known for a while that type of exercise intervention (e.g. intensity, frequency, etc) does not seem to influence self-reported outcomes such as pain. Maybe all the benefits from exercise are explained by non-specific effects, or maybe exercise has benefits that do not depend on the type of exercise. In this episode, I discuss 3 studies that look into (at least partly) other benefits that we may see at the level of the muscle and tendon from higher-load exercise interventions.  References: Radovanović, G., Kunz, J., Bohm, S., Arampatzis, A. and Legerlotz, K., 2021.

This week, I had an engaging conversation with Anthony Nasser, an up-and-coming researcher on tendinopathy who recently completed his PhD on proximal hamstring tendinopathy. Our discussion covered the reasons for the lack of research attention towards this condition, the current state of evidence, and insights from his doctoral studies. You can find the full conversation here.Here are Anthony's related publications: Nasser, A.M., Pizzari, T., Grimaldi, A., Vicenzino, B., Rio, E. and Semciw, A.I., 2021.

Palpation can be useful for the diagnosis and assessment of tendinopathy, but there are limits. This is because non-painful tendons can be tender, and tenderness in painful tendons seems to be very slow to get better.  Link to Evidence for Improvement in Local but not Diffuse Pressure Pain Thresholds Following Physical Therapist Interventions for Tendinopathy: A Systematic Review Link to  Reproducibility and clinical utility of tendon palpation to detect patellar tendinopathy in young basketball playersSee omnystudio.com/listener for privacy information.

Interesting perspective paper from Arampatzis et al talking about how we should consider tuning of muscle tendon unit in terms of muscle strength and tendon stiffness when considering training for specific groups. See omnystudio.com/listener for privacy information.

This talking tendons episode will discuss a study by Igor Sancho, PhD, assessing Achilles forces during common rehab exercises and habitual activities and how this relates to reported pain among runners. Some interesting implications for practice. Achilles tendon forces and pain during common rehabilitation exercises in male runners with Achilles tendinopathy.

In this episode, I am discussing kinesiophobia in the context of tendon rehab and how rehab can be conceptualised as graded exposure for some people.  References 1) Physiotherapy management of Achilles tendinopathySee omnystudio.com/listener for privacy information.

In this episode, I talk about load test pain assessment and how this can also be used to assess kinesiophobia and movement apprehension.  References 1) Physiotherapy management of Achilles tendinopathy: https://pubmed.ncbi.nlm.nih.gov/36274038/ 2) Kinesiophobia Severity Categories and Clinically Meaningful Symptom Change in Persons With Achilles Tendinopathy in a Cross-Sectional Study: Implications for Assessment and Willingness to Exercise: https://pubmed.ncbi.nlm.nih.gov/35295417/See omnystudio.com/listener for privacy information.

This is an interesting study from the Delaware tendinopathy group among others investigating a host of structural, tissue property, functional and pain factors that may persist among people with Achilles tendinopathy making a return to running. Provides guidance to clinicians about potential impairments to consider assessing.  Here's the link to the study: Corrigan, P., Hornsby, S., Pohlig, R.T., Willy, R.W., Cortes, D.H. and Silbernagel, K.G., 2022.

In this episode I talk about three qualitative studies that aim to understand the patient perspective and patient motivations in Achilles tendinopathy. I find this work really helps clinicians to understand what patients are gong through so we are able to be empathic and help them. Hope you enjoy!
