[目的]通过对以往研究中提示与趾握力相关的因素进行分析，探讨趾握力与其相关因素的关系，旨在明确健康女性趾握力的影响因素。[对象与方法]选择12名健康青年女性。他们的脚趾抓地力，角度变化，在他们的踝关节在脚趾抓地力，最大的自主收缩活动的股直肌，股二头肌，胫骨前肌，和内侧头的腓肠肌肌使用肌电图测量。他们的脚趾卷曲能力，足弓高度比，体重也进行了测量。[结果]多元回归分析表明，足趾握力的预测因子为足弓高度比和胫前肌积分肌电图百分比。这表明胫骨前肌%IEMG值和足弓高度比高的女性具有更大的%IEMG值，具有更大的脚趾握力。[结论]足弓高度比与足趾握力之间存在显著的相关性，且存在交互作用。这些研究结果进一步表明，老年人的福尔斯的风险可以降低，如果脚趾的抓地力增强，通过增加的高度低足弓的帮助下插入鞋垫。
[Purpose] This study examined the relationship between toe grip strength and its associated factors by focusing on factors that were suggested to have a relationship with toe grip strength in previous studies, aiming to clarify the factors influencing the toe grip strength of healthy women. [Subjects and Methods] Twelve healthy young women were selected for this study. Their toe grip strength, angular changes in their ankle joint during toe grip, maximum voluntary contraction activities of the rectus femoris, biceps femoris, and tibialis anterior muscles, and the medial head of the gastrocnemius muscles were measured using electromyography. Their toe curl ability, foot-arch height ratio, and weight were also measured. [Results] Multiple regression analysis demonstrated that the predictors of toe grip strength in the resulting model were foot-arch height ratio and the percentage of integrated electromyography (%IEMG) of the tibialis anterior muscle, as the dependent variables. This reveals that women whose tibialis anterior muscle %IEMG values and foot-arch height ratio are high have greater %IEMG values have greater toe grip strength. [Conclusion] These findings suggest a significant relationship between foot-arch height ratio and toe grip strength, with a reciprocal interaction. These findings further indicate that the risk of falls by the elderly could be decreased if toe grip strength were enhanced, by increasing the height of a low foot-arch with the help of an inserted insole.
