Correlation Between Isometric Hip Muscle Strength, Dynamic Balance and Self-Reported Ankle Instability in Recreational Male Football Players with Chronic Ankle Instability: A Pilot Study

Abstract

Background: CAI frequently develops following recurrent lateral ankle sprains in recreational football players and is associated with impaired neuromuscular control, balance deficits, and functional limitations. Deficits in proximal hip muscle strength may alter lower extremity biomechanics and compromise dynamic balance, contributing to persistent ankle instability. Self-reported ankle instability reflects the functional impact of CAI and may be linked with proximal muscle performance and postural control. Objective: To correlate isometric hip muscle strength, dynamic balance, and self-reported ankle instability in recreational male football players with CAI. Method: A pilot study was conducted with 20 male recreational football players with chronic ankle instability. Hip isometric strength was determined using a handheld dynamometer, dynamic balance was evaluated using YBT-LQ, and self-reported ankle instability was evaluated using the CAIT. Results: Significant moderate -to- strong positive correlations was seen between outcome measures. Conclusion: Greater hip muscle strength is associated with better dynamic balance and improved self-reported ankle stability in recreational male football players with CAI, highlighting the importance of hip strengthening in CAI rehabilitation.
