필라테스 리포머 풋 워크 동작시 발의 스탠스가 편평족의 발바닥 근활성도에 미치는 영향

초록

Purpose: Flatfoot which is a deficiency of the medial longitudinal arch of the foot could cause several problems such as pain, malalignment of lower limbs and a decrease of efficient muscle movement. This study is designed to reveal the effect of foot stance on foot muscle activity in flatfoot during Pilates reformer footwork exercise. Methods: Twenty participants who volunteered were divided into the flatfoot group (n=10) and the normal foot group (n=10). All participants measured their muscle(abductor hallucis, flexor digitorum brevis) activation during Pilates footwork movement. It was recorded three times in both stances(wide stance, narrow stance) using wireless EMG system. The average and standard deviation of the muscle activation were used and two-way ANOVA was applied for the data analysis. Result: Flatfoot group showed less foot muscle activity in both stances significantly (p<.01). Both groups showed higher activation in the wide stance but there was no significant difference. Conclusion: The flatfoot group cannot activate their foot muscle compared to the normal foot group. This study provides objective data by comparing foot muscle activation between flatfoot and normal foot, also it could be used to design and apply the effective Pilates method in flatfoot for further studies
