Abstract

Purpose : The aim of this study was to investigate the effects of foot position on dynamic stability in female with genu varum. M ethods: Eight females with genu varum participated in this study and performed the four squat exercise methods that foot position ($-45^{\circ}$, $0^{\circ}$, $+45^{\circ}$) and $0^{\circ}$ 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 ($-45^{\circ}$, $0^{\circ}$, $+45^{\circ}$) and $0^{\circ}$ squat with band method. Results: In anterior-posterior COP displacement, $-45^{\circ}$ foot angle and $0^{\circ}$ squat with band were significantly showed lower than $+45^{\circ}$ foot angle squat (p=0.006). Also, in COP traveled distance, $0^{\circ}$ squat was significantly showed lower than $+45^{\circ}$ 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 $0^{\circ}$ squat with band exercise showed higher dynamic stability and $+45^{\circ}$ foot angle squat exercise showed lower dynamic stability in female with genu varum.
