OBJECTIVES: Analyze associations between lower extremity joint power during the eccentric and concentric phases of a single leg squat and hip symptom duration, hip function, and physical activity levels in individuals with hip joint-related groin pain.
DESIGN: The cross-sectional design of the current study is a secondary analysis of an observational study consisting of a cohort design.
SETTING: Biomechanics Laboratory.
PARTICIPANTS: Twenty-five adults aged 18 to 45 years with current hip pain were recruited for this study.
MAIN OUTCOME MEASURES: Participants self-reported quality of life and physical function using the iHOT-12, current activity level using the Tegner Activity Rating Scale, and hip symptom duration. Lower-limb joint power was calculated using three-dimensional biomechanics data. Spearman's correlation coefficients were used to examine the relationships between parameters.
RESULTS: Our study found that lower hip joint power during the eccentric and concentric phases of a single leg squat task were associated with worse hip function, lower physical activity levels, and a longer duration of hip symptoms.
CONCLUSIONS: These findings highlight the importance of early intervention prior to the onset of severe muscle dysfunction that may lead to corresponding alterations in hip joint loading in individuals with hip joint-related pain.
