Football players with long standing hip and groin pain display deficits in functional task performance. (May 2022) - Roughead, Eliza A.
Abstract: Objectives: i) Compare functional task performance between football players with and without hip/groin pain. ii) Explore the relationship, and sex-specific effects, between functional tasks and the Copenhagen Hip and Groin Outcome Score (HAGOS) in players with hip/groin pain. Design: Cross-sectional. Setting: Laboratory. Participants: 183 (38 women) football players with a self-reported history of >6months of non-time-loss hip/groin pain and a positive flexion-adduction-internal rotation test, and 61 (14 women) asymptomatic players. Main outcome: Participants completed the hop-for-distance (HFD), one leg rise (OLR), side bridge (SB) endurance, and HAGOS. Study aims were assessed using linear models, controlling for body mass index and age, incorporating sex-specific interaction terms. Results: Players with hip/groin pain could not hop as far (adjusted mean difference: -9 cm, 95% CI: -15 cm to -2cm, P= 0.012) and completed fewer OLR repetitions (adjusted mean difference −7, 95% confidence interval −11 to −3 repetitions, P= 0.001) compared to asymptomatic players. Symptomatic women, but not symptomatic men, with worse HAGOS scores had lower SB endurance. Independent of sex, football players with worse HAGOS scores could not hop as far and completed fewer OLR repetitions. Conclusion: Football players with hip/groin pain demonstrated deficits in HFD and OLR with the performance of these tasks associated with their HAGOS results. The study identifies potential impairments that can be targeted as a component of rehabilitation programs for football players with hip/groin pain. Highlights: Football players with hip/groin pain performed worse on functional tasks. A worse HAGOS score was associated with a shorter hop distance. A worse HAGOS score was associated with fewer one leg rises. HAGOS scores were associated with SB endurance in women but not men.
