Toe grip-related training requires individuals to actively exercise muscles that are not frequently used; therefore, it may improve not only toe grip strength but also cognitive function. The purpose of this study was to examine the effects of toe grip-related training on predictors of physical performance and cognitive function in nursing home residents.
A total of 35 nursing home residents (35 left and 35 right feet; mean age, 82.1 ± 7.9 years) were included in this study. The participants were divided into two groups: a training group and a control group. The Mini-Mental State Examination (MMSE) was used to assess the cognitive function of the participants, and the Fall Risk Index (FRI) was used to evaluate the risk of falls. Toe grip-related physical function was also assessed. Baseline endpoints were evaluated and the effects of toe grip-related training were examined following a 12-week training intervention.
The training group showed significant improvements in MMSE score, FRI score, toe grip strength, and the toe skill (TS) test; however, the control group did not show these changes. The training group showed significant increases in Δ MMSE, Δ toe grip strength, and Δ TS (right foot) than the control group. Stepwise regression analysis revealed that Δ toe grip strength is an independent factor of Δ MMSE.
Toe grip training improves not only toe grip strength itself, but also cognitive function. Furthermore, change in toe grip strength was an independent factor of change in MMSE in those populations.

脚趾抓握相关训练需要个体主动锻炼不常使用的肌肉，因此，它不仅可以提高脚趾握力，还可以改善认知功能。本研究旨在探讨脚趾抓握相关训练对养老院居民身体表现和认知功能预测因素的影响。
本研究共纳入 35 名养老院居民（左脚 35 只，右脚 35 只；平均年龄 82.1±7.9 岁）。参与者被分为两组：训练组和对照组。采用简易精神状态检查（MMSE）评估参与者的认知功能，采用跌倒风险指数（FRI）评估跌倒风险。还评估了与脚趾抓握相关的身体功能。评估了基线终点，并在 12 周的训练干预后检查了脚趾抓握相关训练的效果。
训练组的 MMSE 评分、FRI 评分、脚趾握力和脚趾技能（TS）测试均有显著改善；而对照组则没有这些变化。与对照组相比，训练组的 MMSE 差值、脚趾握力差值和 TS 差值（右脚）均显著增加。逐步回归分析显示，Δ脚趾握力是Δ MMSE 的独立因素。
脚趾抓握训练不仅可以提高脚趾握力本身，还可以改善认知功能。此外，在这些人群中，脚趾握力的变化是 MMSE 变化的独立因素。
