🏋️♂️Our study showed feasibility of a 12-week program combining heavy slow resistance training with patient education in gluteal tendinopathy.
doi.org/10.1016/j.ms...
✅ The intervention was safe and feasible, showing promising results that warrant investigation in a RCT.

Just returned from Fukuoka Japan attending the #ISHA2025 Scientific Meeting with great colleagues.
I presented results from the Hip Booster trial, showing that exercise booster sessions are not effective for maintaining effects of exercise in hip OA.

Exercise generally does not increase the breakdown of joints affected by osteoarthritis. However, this has not yet been studied specifically in hip osteoarthritis. Read more – and if you have hip osteoarthritis, you may participate in a scientific study:

Thrilled about engagement at our symposium #ExerciseasMedicine at Aarhus University last week. The overall take-away message for me is how exercise impacts trajectories for healthy ageing and for those who live with disease. There are still challenges, one being how to ensure long-term engagement.

Accumulating evidence suggests that nonsurgical management can play a role before surgery is considered.
Such a strategy carries fewer risks for adverse events and lowers cost without compromising outcomes.

I got lucky and was invited to write a comment for The Lancet Rheumatology: www.thelancet.com/journals/lan...
We discuss evidence gaps in hip OA, propose new avenues for study, and suggest that exercise is still a suitable first-line treatment. Happy to get your 2 cents on these issues.
