简要总结
This study will investigate static and dynamic postural control characteristics in male amateur football players with chronic ankle instability (CAI) compared with football players without ankle instability. Participants will undergo standardized biomechanical assessments using a force-platform-based postural analysis system to quantify postural sway under eyes-open and eyes-closed conditions and to evaluate direction-specific limits of stability performance.
In addition to conventional between-group comparisons, objective balance and stabilization variables will be used to develop supervised machine-learning classification models. These models will examine whether athletes demonstrating CAI-like functional patterns can be identified based solely on biomechanical performance data, independent of self-reported instability questionnaires.
The results are expected to enhance understanding of neuromuscular control deficits associated with chronic ankle instability and to support the development of objective, performance-based assessment approaches for football players.
The aim of this study is to determine the differences in static and dynamic postural control between amateur football players with and without chronic ankle instability and to evaluate whether multidimensional biomechanical balance parameters can be used to objectively characterize CAI-related functional profiles using machine-learning-based analysis.

结局指标
主要结局
Limits of Stability Total Score (%) During Force-Platform Dynamic Postural Control Assessment at Baseline
时间窗: Baseline (single laboratory assessment session)
Dynamic postural control will be evaluated using the limited stabilization (limits of stability) test performed on a force-platform-based postural analysis system. The total limits of stability score (%) reflects the participant's ability to voluntarily control the center of pressure within stability boundaries, with lower values indicating impaired neuromuscular ankle stabilization.
次要结局
- Postural Sway Area (mm²) During Static Balance Assessment With Eyes Open and Eyes Closed at Baseline(Baseline (single laboratory assessment session))
