Brief Summary

This cross-sectional study will gather participant data from clinical assessment and questionnaires for individuals with a clinical diagnosis of Greater Trochanteric Pain Syndrome.

Conditions

Greater Trochanteric Pain Syndrome

Outcome Measures

Primary Outcomes (8)

• Numeric Pain Rating Scale (NPRS)

  The NPRS is a unidimensional measure of pain intensity.Worst and average lateral hip pain over past week will be measured on an 11-point scale between 0 (no pain) and 10 (worst pain imaginable).

  Baseline and 12 months

• Patient Specific Functional Scale (PSFS)

  Function will be assessed using the PSFS. Each participant will identify three activities they are unable to perform or have difficulty performing due to their problem. They rate the difficulty on a scale from 0 (unable to perform) to 10 (able to perform at prior level). I

  Baseline and 12 months

• Victoria Institute of Sports Assessment-GTPS (VISA-G)

  Disability will be measured using the VISA-G questionnaire It is currently the preferred option to capture the disability associated with GTPS and has previously been validated for use in this condition.

  Baseline and 12 months

• Tampa Scale for Kinesiophobia (TSK-17)

  The TSK-17 is a 17-item questionnaire used to assess fear of movement and reinjury. Four-point Likert scales are used. Total scores range from 17 to 68 with a score greater than 37 indicating kinesiophobia.

  Baseline and 12 months

• Depression and Anxiety Stress Scales-21 (DASS-21)

  Anxiety and depression will be measured using the DASS-21 questionnaire.The DASS items are scored on a 4-point scale ranging from 0 (did not apply to me at all) to 3 (applied to me very much, or most of the time). Higher scores indicate more frequent symptomatology.

  Baseline and 12 months

• Pain Self-Efficacy Questionnaire (PSEQ)

  PSEQ is a 10-item questionnaire which measures a person's beliefs about whether they can engage in activities and enjoy life despite experiencing pain. Participants rate how confidently they can perform each activity on a 7-point Likert scale. The total score ranges from 0 to 60, where higher scores reflect stronger self-efficacy.

  Baseline and 12 months

• Euro Qol (EQ-5D-5L)

  The EQ-5D-5L is a five-dimension questionnaire for measuring health-related quality of life. Participants rate their health status on five dimension; mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each of these five dimensions has five statements and each participant will tick one of five boxes for each dimension. An index value (0-1) is calculated from five separate questions. A score of 1 reflects greater quality of life. Each participant also evaluates their current overall health status using a visual analogue scale with a score of 0 indicating the worst imaginable health and a score of 100 the best imaginable health.

  Baseline and 12 months

• International Physical Activity Questionnaire - Short Form (IPAQ-SF)

  The IPAQ-SF is a widely used questionnaire to measure physical activity. The seven questions relate to the amount of time the participant has spent being physically active in the previous 7 days. It covers the domains of leisure time, work-related, transport related and domestic and gardening activities.

  Baseline and 12 months
