[Purpose] The purpose of the present study was to investigate the limb position at which the maximum toe-grip strength could be exerted as well as measurement reproducibility. [Subjects] Twenty healthy young women were selected. [Methods] We measured toe-grip strength under three conditions: 90° hip and knee flexion while sitting, 90° hip flexion and knee extension while sitting, and a standing position. [Results] We found that toe-grip strength was significantly lower in the 90° hip flexion and knee extension sitting position than in the 90° hip and knee flexion sitting position and standing position. Moreover, the 90° hip and knee flexion sitting position produced the best intraclass correlation coefficient (r = 0.813). [Conclusion] The results suggest that 90° hip and knee flexion while sitting is the most suitable limb position for measuring toe-grip strength, as this position allows maximum strength to be exerted and allows measurements to be repeated.
[目的] 本研究旨在探究能够发挥最大足趾握力的肢体位置以及测量的可重复性。[对象] 选取了20名健康年轻女性。[方法] 我们在三种条件下测量足趾握力：坐姿下髋关节和膝关节屈曲90°、坐姿下髋关节屈曲90°且膝关节伸展、站立位。[结果] 我们发现，在坐姿下髋关节屈曲90°且膝关节伸展时的足趾握力显著低于坐姿下髋关节和膝关节屈曲90°以及站立位时的足趾握力。此外，坐姿下髋关节和膝关节屈曲90°时的组内相关系数最佳（r = 0.813）。[结论] 结果表明，坐姿下髋关节和膝关节屈曲90°是测量足趾握力最合适的肢体位置，因为该位置能够发挥最大力量且便于重复测量。
