Talking Tendons

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.

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!

This paper is more than 30 years old but it is a beauty. Farley et al talk about human preferred hopping frequency and how it relates to metabolic cost and how fast muscles are contracting, and also how our instructions can influence how well people hop (and the mechanisms that drive this). Important to consider hopping instruction when assessing submaximal hopping in the clinic.  Here's a link to the paper Farley, C.T., Blickhan, R., Saito, J. and Taylor, C.R., 1991.

There is so much debate about the use of steroids for tendinopathy. Opinions vary between 'you should never use steroid as will lead to recurrence, worse pain or rupture' to 'it's fine, do as much steroid as you like'. Opinions dominate as we have limited data. Until now. This is the first trial looking at 2 year outcome for exercise +/- steroid for Achilles tendinopathy. Interesting findings! See omnystudio.com/listener for privacy information.

This is a new and lovely to read randomised trial comparing pain science education (including lots of good biopsychosocial info) versus placebo education for Achilles tendinopathy. Some interesting findings and potential avenues for further study. Definitely worth a listen and read.  Here is a link to the actual paper:  https://journals.lww.com/pain/Abstract/9900/The_effects_of_pain_science_education_plus.122.aspx See omnystudio.com/listener for privacy information.

This is a new study from my PhD student, Igor Sancho. He looks at strength, psychological and other factors that may be different between health runners and runners with Achilles tendinopathy. Seated calf raise 6RM seems to be the strongest predictor of having Achilles tendinopathy. Some interesting other findings and clinical implications.  Here is a link to this paper, and Igor's other PhD papers: Sancho, I., Morrissey, D., Willy, R.W., Tayfur, A., Lascurain-Aguirrebeña, I., Barton, C. and Malliaras, P., 2022.

On this episode I focus on a new study from my PhD student Eman Merza. It is a cross-over randomised trial testing the effect of high and low contraction time and high and low intensity isometric contractions on acute changes to tendon volume and stiffness. Some very interesting potential insights for tendon adaptation. Good work, Eman!

Had a lovely chat with Shawn Hanlon who is a PhD candidate about his relatively new paper exploring patient features and clinical characteristics and how they may define certain subgroups of Achilles tendinopathy . Lots more to learn in this field and this is early work, but we discuss some of the juicy potential clinical implications. Hope you enjoy!

There is lots of debate about the pain mechanisms, particularly if there are central changes, in Achilles and other tendinopathies. Most studies in the literature use proxy measures of central sensitisation like pressure pain threshold away from the painful site, Other measures like conditioned pain modulation have been investigated less frequently. In this episode of talking tendons I discuss a huge new study investigating CPM in Achilles tendinopathy with some interesting findings and implications. Hope you enjoy!

Patients often ask about dietary supplements and if they may be helpful in recovering from a tendinopathy problem. There is a new systematic review out which has attempted to answer this question and it is the subject of this episode of talking tendons. I hope you enjoy.    Here is the reference Qiu, F., Li, J. and Legerlotz, K., 2022. Does Additional Dietary Supplementation Improve Physiotherapeutic Treatment Outcome in Tendinopathy?

We all understand providing education for people with rotator cuff tendinopathy (and other conditions) is really important but we have very few resources or guidance regarding what should be delivered and how. In this episode I discuss two qualitative studies exploring the views of patients and expert clinicians about what needs to be included in education for rotator cuff tendinopathy. We the findings to develop an education resource which is embedded in one of the papers (Cridland et al). Some interesting insights - I hope you enjoy.  Here are links to the papers: White, J., Mc Auliffe, S., Jepson, M., Burstein, F., Hopman, R., Morrissey, D., Haines, T. and Malliaras, P., 2020. ‘There is a very distinct need for education'among people with rotator cuff tendinopathy: An exploration of health professionals' attitudes. Musculoskeletal Science and Practice, 45, p.102103. https://pubmed.ncbi.nlm.nih.gov/32056827/ Cridland, K., Pritchard, S., Rathi, S. and Malliaras, P., 2021. ‘He explains it in a way that I have confidence he knows what he is doing': A qualitative study of patients' experiences and perspectives of rotator‐cuff‐related shoulder pain education. Musculoskeletal Care, 19(2), pp.217-231.Vancouver https://pubmed.ncbi.nlm.nih.gov/33258225/  See omnystudio.com/listener for privacy information.

Hi All, On this talking tendons episode, I dive into the very murky world of isometric exercise and their effect on tendon pain. A new study by Sinead Holden and team brings some (just a little) light to the evidence. I argue that isometrics are useful for managing tendinopathy, but using them for short term pain reduction is just the tip of the iceberg. Also if you're wanting to earn some extra CPD before Christmas check out my two upcoming workshops in December in Sydney and Melbourne (bookings).

Hi All, In this episode of Talking Tendons I have an enjoyable chat with PhD student and Spanish physio, Igor Sancho. He has recently published a study that assessed the feasibility of using jumping and hopping as rehabilitation for people with Achilles tendinopathy. We discuss the study and how to apply these findings in clinic.

Isometric exercise for tendinopathy has exploded onto the scene over the last few years. Unfortunately, the certainty of evidence surrounding their use is far less certain and compelling than what we are told about them but some people. They may work, but the reality is we don't fully understand how and for whom. This episode delves into this uncertainty and provides lots of top tips for how to use isometrics and when they are useful. Enjoy!

Despite our best intentions, not everyone with tendinopathy will respond to conservative treatments. Clinicians need alternative options like injection therapy. Injections such as steroid and platelet-rich plasma continue to be popular for tendinopathy, and there are other emerging injections such as the high-volume injection.   Injection TherapyIn Tendinopathy: Art & Science - 4th May 2019 MELBOURNE booking via link below: https://www.eventbrite.com.au/e/injection-therapy-in-tendinopathy-art-and-science-tickets-57953819434

Understanding how tendon recovers from injury and adapts to load is so important and has huge implications on how we manage tendons and the education and advice that we provide patients. This podcast features a relatively new study providing insights into the collagen turnover in healthy tendons and those with tendinopathy, adding critical knowledge to what we know about tendon collagen adaptation over time.  

In this week's podcast, I delve into the minefield that is isometric exercise. Is it the best thing since sliced bread? Does everyone respond? What are the key questions we need to understand?

In this podcast we consider some new research exploring psychological factors and tendinopathy. There is emerging evidence that, as per other musculoskeletal conditions and as you would expect, they do play a role. I discuss which ones appear to be most strongly linked with tendinopathies.

Hi all, this episode we focus on two recent randomised controlled trials evaluating education and exercise interventions for gluteal tendinopathy, One of them is the best RCT I have read in ages. Well worth a look at their methods, findings and exercise interventions. Hope you enjoy!

This episode we focus on technology use in rehab. I'm inspired by the patient will see you now by Dr Eric Topol which I recently read so this weeks podcast covers 2 technology focused systematic reviews. The first is on the efficacy of exergames for treating musculoskeletal pain, and the second is on basically the use of accelerometers and other wearable sensors to monitor rehab exercises. An exciting area that is set to grow hugely and will be part of all of our practices soon.   References to include at the bottom of the podcast and blog:   O’Reilly M, Caulfield B, Ward T, Johnston W, Doherty C.
