This study aimed to investigate the relationship of Functional Independence Measure for motor function (FIM-M) with sarcopenia, and physical activity in patients with stroke undergoing rehabilitation. This cross-sectional study included patients with stroke at a single convalescent rehabilitation hospital. Sarcopenia was diagnosed based on the Asia Working Group for Sarcopenia 2019 criteria. Physical activity was measured as the duration of light-intensity physical activity and moderate to vigorous physical activity using a triaxial accelerometer. Of 80 patients (median age: 72.0 years), 46 (57.5%) were diagnosed with sarcopenia. In multivariate linear regression analysis, FIM-M score was significantly associated with sarcopenia (β = −0.15, p = .043) and light-intensity physical activity (β = 0.55, p < .001). In another model, FIM-M score was significantly associated with moderate to vigorous physical activity (β = 0.27, p = .002) but not with sarcopenia. This study demonstrated that FIM-M was partially associated with sarcopenia and associated with physical activity regardless of intensity in patients with stroke.

本研究旨在调查运动功能的功能独立性测量 (FIM-M) 与肌肉减少症以及接受康复治疗的中风患者的身体活动之间的关系。这项横断面研究纳入了一家康复康复医院的中风患者。肌肉减少症是根据亚洲肌肉减少症工作组 2019 年标准诊断的。使用三轴加速度计测量体力活动的持续时间，即光强度体力活动和中度至剧烈体力活动的持续时间。在 80 名患者（中位年龄：72.0 岁）中，46 名 (57.5%) 被诊断为肌肉减少症。在多元线性回归分析中，FIM-M 评分与肌肉减少症 (β = −0.15, p  = .043) 和光强度体力活动 (β = 0.55, p = .043)显着相关p  <.001）。在另一个模型中，FIM-M 评分与中等到剧烈的身体活动显着相关（β = 0.27，p  = .002），但与肌肉减少症无关。这项研究表明，无论中风患者的强度如何，FIM-M 与肌肉减少症部分相关，并且与体力活动相关。
