Exercise and Patient Education for Patients With Lateral Hip Pain

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.

About this study

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.

Treatment and study plan

Exercise and Patient Education

Procedure

Patients will undergo a 12-week physiotherapist-led exercise program consisting of 8 supervised sessions and home-based training in between.

Patients will keep training diaries, where each session is tracked in regards of completed repetitions and pain before and after the sessions. Each session will consist of four exercises.

Primary outcomes

    Time frame: From baseline to 3 months follow-up. The outcome is also conducted at 6-week follow-up.

    The subscale "pain" on HAGOS measures the patients perception of hip and/or groin pain. It consist of ten items. A score from 0 to 100 is calculated, where a higher score is indicating lower pain.

Secondary outcomes

    The subscale "symptoms" on HAGOS measures the patients perception of hip and/or groin pain. It consist of seven items. A score from 0 to 100 is calculated, where a higher score is indicating lower symptoms.

  2. Changes in patient-reported physical function in daily living (ADL) measured with the revised Copenhagen Hip And Groin Outcome Score (HAGOS) (continuous data)

    Time frame: From baseline to 3 months follow-up. The outcome is also conducted at 6-week follow-up.

  3. Changes in patient-reported physical function in sport and recreational activities (sport/recreation) measured with the revised Copenhagen Hip And Groin Outcome Score (HAGOS) (continuous data)

    Time frame: From baseline to 3 months follow-up. The outcome is also conducted at 6-week follow-up.

  4. Changes in patient-reported participation in physical activities (PA) measured with the revised Copenhagen Hip And Groin Outcome Score (HAGOS) (continuous data)

    Time frame: From baseline to 3 months follow-up. The outcome is also conducted at 6-week follow-up.

    The subscale "PA" on HAGOS measures the patients perception of hip and/or groin pain. It consist of two items. A score from 0 to 100 is calculated, where a higher score is indicating higher ability to participate in physical activity.

  5. Changes in patient-reported quality of life (QOL) measured with the revised Copenhagen Hip And Groin Outcome Score (HAGOS) (continuous data)

    Time frame: From baseline to 3 months follow-up. The outcome is also conducted at 6-week follow-up.

    The subscale "QOL" on HAGOS measures the patients perception of hip and/or groin pain. It consist of five items. A score from 0 to 100 is calculated, where a higher score is indicating higher quality of life.

  6. Changes in the patient-reported outcome measure Oxford Hip Score (continuous data)

    Time frame: From baseline to 3 months follow-up. The outcome is also conducted at 6-week follow-up.

    Oxford Hip Score (OHS), which consists of 12items. OHS is developed and validated for patients undergoing total hip replacements to access pain and function. It is a composite score ranging from 0 (worst) to 48 (best).

  7. Changes in the patient-reported outcome measure EQ-5D-5L (continuous data)

    Time frame: From baseline to 3 months follow-up. The outcome is also conducted at 6-week follow-up.

    European Questionnaire-5 Dimensions (EQ-5D-5L and EQ-VAS) consists of five items and a visual analogue score (VAS), a vertical line on which the patients score their perception of their overall health from 0 to 100 (worst to best)

  8. Global Rating of Change (GRoC)

    Time frame: The outcome is conducted at 6-week and 3-months follow-up.

    GRoC consists of a 11-point scale, where the patient rates the perceived overall change of the hip condition from "very much better" to "very much worse" . Responses on GRoC will be considered successful if patients scored "moderately better" to "very much better". Global improvement will be measured as the percentage of successful reports.
