本研究的目的是探讨步行时肌肉力量不对称与身体摆动的关系。我们研究了63名老年女性。测量强侧和弱侧伸膝力量、脚趾握力、手掌握力和行走时的身体摆动。用皮尔逊相关系数评价各肌肉力量不对称性与行走时身体摆动的关系。对于被认为与身体摇摆有显著相关性的肌肉，计算了导致摇摆增加的不对称截止值。脚趾握力不对称与身体摆动显著相关。导致身体摆动增加的脚趾握力不对称的截止值为23.5%。我们的发现表明，脚趾握力不对称可能是改善步态稳定性的一个目标。
The purpose of this study was to investigate the relationship between muscle strength asymmetry and body sway while walking. We studied 63 older adult women. Strong side and weak side of knee extension strength, toe grip strength, hand grip strength, and body sway while walking were measured. The relationship between muscle strength asymmetry for each muscle and body sway while walking was evaluated using Pearson's correlation coefficient. Regarding the muscles recognized to have significant correlation with body sway, the asymmetry cutoff value causing an increased sway was calculated. Toe grip strength asymmetry was significantly correlated with body sway. Toe grip strength asymmetry causing an increased body sway had a cutoff value of 23.5%. Our findings suggest toe grip strength asymmetry may be a target for improving gait stability.
