Exercise Rehabilitation for Hip-related Pain and Dysfunction in Student Circus Arts Performers

Not Applicable

Recruiting

• Conditions: Hip Dysplasia; Femoro Acetabular Impingement
• Interventions: Other: Hip Exercise Program

• Registration Number: NCT05687955
• Lead Sponsor: Swinburne University of Technology

Brief Summary

Hip injuries are reported to account for 71% and 29% of all injuries reported in female and male performers, respectively, at the National Institute of Circus Arts. There are no reports on hip pathology in circus performers, nor are there any reported exercise interventions for hip pain in circus performers.

This study aims to:

To assess the effect of an exercise rehabilitation program on patient-reported outcome measures, hip strength and range of movement, and functional assessments in circus arts students with clinically and radiologically diagnosed hip pain-related disorders.

Participants will undertake a 12-week strength exercise protocol that has been specifically designed to focus on hip rehabilitation appropriate for circus performance. Expected outcome: Improvements in patient reported outcome measure (PROM) scores and an increase in function, strength and hip range of movement in people with hip pain

Arm && Interventions

Group	Intervention	Description
Hip Exercise Program	Hip Exercise Program	A 12-week strength exercise protocol has been specifically designed to focus on hip rehabilitation appropriate for circus performance.

Primary Outcome Measures

Name	Time	Method
European Quality of life questionnaire (EQ-5D-5L)	9-months	Patient Reported Outcome Measure
Tampa Scale of Kinesiophobia (TSK)	9-months	Patient Reported Outcome Measure
Hip Strength assessment	9-months	Strength of hip abduction, adduction, sitting hip flexion at 90deg, prone extension with knee extended, prone external and internal rotation will be measured using a hand-held dynamometer.
Hip Range of Motion	9-months	Hip flexion, Hip internal rotation and external rotation will be measured using an inclinometer
The Copenhagen Hip and Groin Outcome Score (HAGOS)	9-months	Patient Reported Outcome Measure, score on 0-100 scale, with zero representing extreme hip and/or groin problems and 100 representing no hip and/or groin problems.
International Hip Outcome Tool (iHOT-12)	9-months	Patient Reported Outcome Measure scored using a visual analog scale from 0 to 100, with a score of 100 being the best function and least amount of symptoms

Secondary Outcome Measures

Name	Time	Method
Trunk Muscle Endurance Test	9-months	The duration of a side-plank will be recorded in seconds/minutes. The test will be ceased after 3 minutes.
One leg rise test	9-months	The number of sit to stand movements on a single leg performed from a starting position where the knee is at 90deg will be recorded. The test will be ceased if the participant reaches 50 one leg rises.
Single leg Hop for distance	9-months	The distance of a participant hop will be measured, taking off and landing on the same foot, maintaining their balance for about 2-3 seconds on landing. The best of three hops will be recorded.
Functional movement screen Y-balance test	9-months	This will measure a circus performers capacity to stand on one leg and reach their opposite leg as far as possible forwards, backwards and sideways. This provides a measure of both strength and flexibility, has been used in prior hip research, and shown to have excellent intra and inter-rater reliability.
