Physiotherapist-led education and exercise for patients with MRI-verified hip abductor tendon pathology: a protocol...

Lateral hip pain due to hip abductor tendon pathology (ie, gluteal tendinopathy or tendon rupture) is a relatively new diagnosis. This patient group has previously been described as a clinical dilemma due to the often-short-lived effects of treatment. In the process of identifying the underlying pathology, however, more targeted treatment strategies have been explored. Recent research recommends exercise as a first-line treatment for this patient group along with patient education. However, patients seen in a hospital setting (secondary healthcare) often present recalcitrant lateral hip pain, tendon ruptures and multiple comorbidities. Whether patient education and exercise therapy are beneficial for patients in secondary healthcare has only been sparsely investigated. Therefore, this study aims to investigate changes in lateral hip pain following a 3 month physiotherapist-led patient education and exercise intervention in patients with MRI-proven hip abductor tendon pathology seen in a hospital setting.

In this prospective cohort trial, 60 patients, presenting lateral hip pain and MRI-verified hip abductor tendon pathology at the orthopaedic outpatient clinic at Horsens Regional Hospital, Denmark, a public teaching hospital, are included. Hip abductor tendon pathology will be diagnosed by clinical tests and MRI. The intervention consists of seven physiotherapist-led patient education and exercise sessions at the hospital during 3 months. The instructions will guide the patients in their daily home-based exercise sessions.The primary outcome is change in lateral hip pain measured by the 'pain' subscale from the patient-reported outcome measure: the revised Copenhagen Hip And Groin Outcome Score (HAGOS). Secondary outcomes are changes in the remaining subscales of the revised HAGOS, Oxford Hip Score, Victorian Institute of Sports Assessment-Gluteal Questionnaire, European Questionnaire-Five Dimensions Five-Level, lateral hip pain (numeric rating scale score, 0-10), hip muscle strength and the 30 s chair stand test. Also, patient-reported Global Rating of Change in hip condition, as well as adherence and harms, will be reported.

This trial has been accepted by the Central Denmark Regions Ethics Committee (1-10-72-136-22). The study is registered at the Central Denmark Region List of Research Projects (Journal No 1-16-02-180-24) and clinicaltrials.gov (NCT06418217).All results from this study, regardless of the direction, will be published in a peer-reviewed journal and presented at national and international congresses.
