Exercise and Patient Education for Patients With Lateral Hip Pain

3 Months Semi-supervised Exercise Intervention for Patients With Hip Abductor Tendon Pathology (HATP): A Prospective Clinical Cohort Study

This prospective cohort trial will investigate a progressive exercise protocol and patient education for patients with hip abductor tendon pathology. The primary outcome is patient reported pain measured by the revised Copenhagen Hip And Groin Outcome Score (HAGOS), that will be conducted at baseline and at a 12 week follow-up.

This study protocol describes an interventional pragmatic prospective single-group cohort study, where the primary endpoint is change in hip pain measured with the revised HAGOS pain subscale following a 12 week intervention. Throughout the 12 weeks, eight physiotherapist-led exercise sessions will take place at Horsens Regional Hospital (HRH). Further, at the sessions at HRH patient education will be performed by the supervising physiotherapist. The first supervised sessions will be performed in continuation of the baseline assessment. The patients will be instructed to do the exercises daily at home in the time period between the physiotherapist-led sessions.

The primary aim is to investigate changes in patient-reported hip pain based on the subscale "pain" from the revised Copenhagen Hip And Groin Outcome Score (HAGOS) from baseline to 12 week follow-up.

It is hypothesized that the revised HAGOS pain score will improve from baseline to 12 week follow-up.

Secondarily explorative subgroup analyses regarding whether patients with different MRI findings, pain profiles, age, sex and body mass index (BMI) respond differently to the intervention, will be performed.

All outcomes conducted will be published. That is, patient-reported outcomes, muscle strength, functional capacity and adherence to the exercise protocol.

A full study protocol will be published and made available.
