Overview
Brief Summary
This pilot randomised controlled trial will directly compare the effect of isometric exercise to isotonic exercise over a period of 12 weeks for participants with a clinical diagnosis of Greater Trochanteric Pain Syndrome (GTPS).
Detailed Description
Pain at the side of the hip over or around the greater trochanter of the femur has previously been termed as Greater Trochanteric Pain Syndrome (GTPS). Recent research has found that it is normally due to the gluteal tendons being torn or injured and is often termed as 'gluteal tendinopathy'. GTPS predominantly affects adults aged 40-60 years and is the second most common condition affecting the hip region after osteoarthritis. Quality of life scores are similar to those with advanced hip osteoarthritis but despite its prevalence and disease burden the most effective treatment for this problem is currently unknown. Numerous studies have shown that exercise programmes are the most effective treatment for other lower limb tendon problems, particularly the Achilles and patella. These programmes typically last a minimum of 12 weeks and are often prescribed by physiotherapists as first-line treatment. However, there is currently limited evidence to support exercise for gluteal tendinopathy. The study plans to directly compare two different types of exercise programmes for those with GTPS for a period of 12 weeks. One group will receive an isometric exercise programme (where the muscle length does not change) and a second group an isotonic exercise programme (where the muscle length does change). The primary outcome measure which will be used has recently been validated for patients with gluteal tendinopathy and measures function and disability. Additional secondary outcome measures will evaluate aspects relating to quality of life, physical activity and pain. Both groups will be compared at the start of the study and at different times up to a maximum of 12 weeks to help determine if one exercise programme is better than the other. The results of this pilot study will also help to identify whether a larger trial would be possible in the future.
