| Popis: | 高齢者では足部機能低下が転倒原因の一つとして報告されている。本研究は、日常生活における草履式鼻緒サンダル（草履）の着用が、中高齢女性の足部機能にどのような影響を及ぼすのか明らかにすることを目的とした。対象は、地域在住の40 歳から81 歳までの健常な中高齢女性22 名（平均年齢65.5 ± 9.9 歳）であった。6 ヶ月間、日常生活で草履を着用してもらった。草履導入前後に足趾把持力、足趾挟力、片足ステッピングおよび静止立位時の足圧分布等を測定した。結果、足趾把持力および片足ステッピングに有意な変化は認められなかったが、足趾挟力は有意に高まった。また、接地面積の減少および足圧中心位置の矢上（前方）偏位が認められた。足部形態（土踏まず等）に変化が認められる者も多く、草履着用による足部機能改善の可能性が示唆された。 This study clarified the influences of wearing Japanese-style sandals （zori） on function of foot in middle-aged and elderly women. The participants were 22 healthy women, aged between 40 and 81 years. They wore sandals as indoor or outdoor shoes for six months. Toe-gap force, toe-grip strength, and one leg stepping test were evaluated. Additionally, the soles’ ground contact area, position of the center of foot pressure （COP）, and track length of center of pressure （T-COP） were measured before and after six months with a plantar pressure measurement device. There were no significant differences between baseline and six months regarding toe-grip strength and one leg stepping test. In zori group, means for toe-gap force improved significantly between baseline and six months. Two-way ANOVA （analysis of variance） revealed the mean differences between the groups as well as the before‒after ground contact area and COP. In zori group, the ground contact area became smaller due to the foot’s arch formation. As for COP, the zori group（ p < 0.05） showed significant change, becoming more forward to the toe, but the control group did not. The findings in our study indicate that zori can be useful in improving foot function through toe-gap force enhancement and adjustment of the pressure pattern. |
