[目的]比较有无踝关节固定带时的趾握力和趾握力施加时的肌肉活动，并探讨肌肉活动差异与趾握力之间的关系。[受试者]受试者为13名健康年轻女性。[方法]采用肌电描记法测量在踝关节制动带存在和不存在的情况下，脚趾握力和脚趾握力过程中的肌肉活动。记录以下腿部肌肉的活动：股直肌、股二头肌、腓肠肌内侧头和胫骨前肌。然后我们计算了脚趾夹持过程中积分肌电图的百分比。[结果]踝带制动组的足趾握力和腓肠肌内侧头积分肌电图百分比显著高于非踝带制动组。此外，在踝带制动的存在下，胫骨前肌和腓肠肌内侧头的百分比积分肌电图表现出与脚趾握力呈正相关（r = 0.75和r = 0.65，分别）。[结论]踝关节带制动可以提高足趾握力。测量值反映了小腿肌肉的积分肌电图百分比。因此，表明应在固定带存在的情况下测量脚趾抓力。
[Purpose] The aim of this study was to compare toe grip strength and muscle activity during toe grip strength exertion according to the presence/absence of an ankle immobilization belt and to examine the relationship between the differences in muscle activity and toe grip strength. [Subjects] The Subjects were 13 healthy young women. [Methods] We measured toe grip strength and muscle activity during toe grip strength exertion in the presence and absence of an ankle immobilization belt using electromyography. Activity in the following leg muscles was recorded: rectus femoris, biceps femoris, medial head of the gastrocnemius, and tibialis anterior. We then calculated the percent integrated electromyography during toe gripping. [Results] Toe grip strength and percent integrated electromyography of the medial head of the gastrocnemius muscle were significantly higher with ankle belt immobilization compared with without ankle belt immobilization. In addition, in the presence of ankle belt immobilization, the percent integrated electromyography of the tibialis anterior muscle and medial head of the gastrocnemius muscle demonstrated a positive correlation with toe grip strength (r = 0.75 and r = 0.65, respectively). [Conclusion] These findings suggest that greater toe grip strength could be exerted in the presence of ankle belt immobilization. The measured values reflect the percent integrated electromyography of the crural muscles. Therefore, it was shown that toe grip strength should be measured in the presence of an immobilization belt.
