| Abstract: | The purpose of this study was to clarify how movement is controlled at the first step by the swing leg of gait initiation on a low friction floor. Nine healthy subjects (age: 22.6 ± 3.0 years) participated in the study. On both high and low friction floors, movements of the first step were measured using a force plate and a motion analysis system. The length of the first step and the time difference from heel contact to toe contact by the swing leg on the low friction floor were significantly smaller than those on the high friction floor, and the maximum vertical distance between the lateral malleolus of the swing leg and the floor on the low friction floor was significantly higher than that on the high friction floor. These findings suggest that the movement of the first step of gait initiation on a low friction floor may be controlled in such a way that the step length is reduced, the foot is raised higher, and the foot lands flat on its sole. | | 本研究の目的は，低摩擦床面において歩行開始1歩目の動作がどのようにコントロールされているかを明らかにすることである。対象は，9名の健常者であった（年齢：22.6±3.0歳）。高摩擦床面と低摩擦床面において歩行開始1歩目の動作を，1枚のフォースプレートと動作解析システムを用いて測定した。その結果，1歩目の歩幅と遊脚肢の踵接地時から足底接地時までの時間差は，低摩擦床面では高摩擦床面の場合よりも有意に減少し，遊脚肢の外果と床面との最大垂直距離は低摩擦床面では高摩擦床面の場合よりも有意に増加していた。これらの知見から，低摩擦床面における歩行開始1歩目の動作は，歩幅を減少させ，足部を高く上げ，踵接地時はフットフラットになるようにコントロールされることが示唆される。 |
