Abstract:
PURPOSE: The aim of this study was to investigate the effects of foot position on dynamic stability in female with genu varum. METHODS: Eight females with genu varum participated in this study and performed the four squat exercise methods that foot position (−45°, 0°, +45°) and 0° squat with band. Center of pressure (COP; anterior-posterior, medial-lateral, traveled distance, ellipse area) and ground reaction force as dynamic stability were measured using footscan system. Multivariate analysis of variance and one-way repeated analysis of variance measurement with Tukey honestly significant difference were used to identify significant differences of foot angle (−45°, 0°, +45°) and 0° squat with band method. RESULTS: In anterior-posterior COP displacement, −45° foot angle and 0° squat with band were significantly showed lower than +45° foot angle squat (p=0.006). Also, in COP traveled distance, 0° squat was significantly showed lower than +45° foot angle (p=0.019). During the descending phase, ground reaction force significantly showed in −45 foot angle was lower than other exercise methods. CONCLUSION: The 0° squat with band exercise showed higher dynamic stability and +45° foot angle squat exercise showed lower dynamic stability in female with genu varum.
