正常年輕族群以足外八著地角度行走會增加內側地面反作用力

Abstract

Objective: The purpose of this study was to determine how toe-out foot landing position influences ground reaction forces (GRF) during gait.Design: Values of GRF components recorded with a force platform were used to compare 3D GRF vectors of toe-out and non toe-out (including neutral and toe-in) foot landing positions. Methods: Thirty-two healthy males (ranging from 19-21 years old) were repeatedly assigned three foot landing positions: maximum toe-out, maximum toe-in and neutral. Each participant walked with three foot landing positions across a force platform while their three-dimensional motion was captured. Results: No differences were observed for vertical or anteroposterior GRF among three foot landing positions (p>0.05). For mediolateral GRF, higher medial loading forces appeared at the first and second peaks in toe-out landing position when compared with non toe-out gaits (p<0.05). Also earlier and later occurrences appeared at the 1st and 2nd peaks in toe-out landing position respectively (p<0.05). Conclusion: We provide evidence of toe-out, toe-in and neutral foot landing positions on GRF using a kinetic study. It is suggested that individuals who walk with greater degrees of toe-out angle create greater medial GRF during the contact and propulsive phases.
