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

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
