Abstract

This study aimed to investigate the effect of enhancing abductor hallucis (AbH) contraction by electrical stimulation (es) on foot biomechanics in gait. Ten healthy adults were recruited for this study. Ground reaction forces (GRFs) and navicular tuberosity (NAV) movement were recorded with and without AbH es during walking. The results showed that enhancing the AbH contraction reduced the range of motion of the NAV height (p=0.030). Meanwhile, the medial GRF was higher in the final stance and the center of pressure (COP) was laterally shifted in the whole stance phase. In conclusion, enhancing AbH contraction could stiffen the foot arch in gait and aid the body shift to the contralateral side in the final stance which may have the potential to inspire the intervention for individuals with arch collapse.
