Abstract

Objectives

To investigate isometric and isokinetic hip strength as well as dynamic balance in males with chronic ankle instability (CAI) and explore potential associations between hip strength, dynamic balance, and self-reported instability.

Design

Cross-sectional study.

Setting

University laboratory.

Participants

Fifty male participants (25 with CAI and 25 healthy controls).

Main outcome measures

Hip isometric and isokinetic torque normalized to body weight, Lower Quarter Y-balance Test (YBT-LQ), the Polish version of The Cumberland Ankle Instability Tool (CAIT-PL).

Results

Significant differences were observed only in the hip isometric abductors/adductors strength ratio (p = 0.034, ES = 0.65), which was lower in the CAI group. CAI participants showed reduced dynamic balance in posterolateral reach (p = 0.006, ES = 0.92) and composite score of YBT-LQ (p = 0.012, ES = 0.91). There was a moderate positive correlation between dynamic balance and hip abductors strength during posteromedial (r = 0.40, p = 0.049) and posterolateral (r = 0.40, p = 0.048) YBT-LQ reaches, and isometric hip abductors strength moderately positively correlated with self-reported instability (r = 0.46, p = 0.021) in the CAI group.

Conclusion

Males with CAI exhibit deficits in frontal plane hip isometric strength, specifically in the hip abductor/adductor ratio, while no deficits were observed in isokinetic strength. The relationships between hip abductors strength, dynamic balance, and self-reported ankle instability may suggest the importance of hip abductors isometric strength for functional outcomes in CAI-patients.

期刊介绍： Physical Therapy in Sport is an international peer-reviewed journal that provides a forum for the publication of research and clinical practice material relevant to the healthcare professions involved in sports and exercise medicine, and rehabilitation. The journal publishes material that is indispensable for day-to-day practice and continuing professional development. Physical Therapy in Sport covers topics dealing with the diagnosis, treatment, and prevention of injuries, as well as more general areas of sports and exercise medicine and related sports science. The journal publishes original research, case studies, reviews, masterclasses, papers on clinical approaches, and book reviews, as well as occasional reports from conferences. Papers are double-blind peer-reviewed by our international advisory board and other international experts, and submissions from a broad range of disciplines are actively encouraged.
