About this trial
Greater Trochanteric Pain Syndrome (GTPS) is a condition that causes pain on the outer side of the hip. This clinical trial tests a simple exercise timing approach for adults with GTPS.
The main questions it aims to answer are:
* Can enough people with GTPS be recruited and complete this study? * How many participants fill in their questionnaires at all five check-ins? * Do participants find the exercise timing approach easy and acceptable?
Researchers will compare three groups. Each group receives different guidance on when to do their exercises. This will show whether timing guidance (with or without reminders) works better than usual care.
Participants will:
* Follow a prescribed hip exercise programme set by their healthcare provider * Fill in a short daily survey (1-2 minutes) for 28 days * Complete online questionnaires about hip pain, movement, and exercise at five - points over about three months * Join an online group discussion at the end of the study
Adults aged 18 and over may take part if they:
* Have been diagnosed with GTPS by a healthcare provider * Are able to exercise safely * Own a mobile phone
Taking part may help participants keep up with their prescribed exercises, which may in turn reduce hip pain and improve daily activities. It could also help researchers find better ways to support people with GTPS in the future.

Trial outcomes
Primary outcomes
Recruitment Rate
The number of patients invited to participate and the number who provide informed consent at end of recruitment period.
Retention Rate
The number of participants who withdraw from the study and those who do not complete their scheduled online follow-up questionnaires.
Completion Rate
The proportion of participants who fully complete all outcome measurement scales at each scheduled assessment point.
Secondary outcomes
The Exercise Adherence Scale (EXAS)
A five-item daily self-report survey completed online for 28 consecutive days. The survey takes approximately 1-2 minutes to complete. It captures both exercise adherence (whether exercises were done) and exercise timing (when they were done), which is the primary focus of the ASAP intervention.
The Exercise Adherence Rating Scale (EARS)- Section B
A validated patient-reported outcome measure developed to assess adherence to home exercise programmes in people with musculoskeletal conditions. Section B specifically captures participants' reasons for not fully adhering to their prescribed exercise programme, including barriers such as pain, time constraints, and forgetting.
Morningness-Eveningness Questionnaire (MEQ)
A validated 19-item self-report measure developed by Horne and Östberg (1976) to assess chronotype - an individual's natural preference for morning or evening activity. Participants select their preferred times for sleeping, waking, and performing tasks across a range of scenarios. Total scores range from 16 to 86, with higher scores indicating a stronger morning preference. Scores are classified into five chronotype categories: definitely morning type (70-86), moderately morning type (59-69), intermediate type (42-58), moderately evening type (31-41), and definitely evening type (16-30).
Victorian Institute of Sport Assessment - Gluteal Tendinopathy (VISA-G)
A validated 8-item patient-reported outcome measure developed by Fearon et al. (2015) specifically to assess pain and function in individuals with gluteal tendinopathy. Items cover pain during daily activities, functional ability, and capacity to participate in sport or work. Total scores range from 0 to 100, with higher scores indicating less pain and better function. A score of 100 represents full asymptomatic participation in all activities.
