[Purpose] To compare changes in skeletal muscle mass after stroke based on the severity of motor dysfunction. [Participants and Methods] This study included 17 patients who had experienced a stroke. Patients were classified into two groups based on lower limb Brunnstrom stages, i.e., those with stages III and IV (moderate motor dysfunction group; n=9), and those with stages V and VI (mild motor dysfunction group; n=8). Muscle mass was measured at the following time points: within 3 days of stroke onset; at 2 weeks ± 2 days after stroke onset; at 4 weeks ± 2 days after stroke onset; at 8 weeks ± 2 days after stroke onset, and muscle mass indices, i.e., the skeletal muscle mass index (SMI), paralyzed lower limb muscle mass, and non-paralyzed lower limb muscle mass were evaluated. Changes in these muscle mass indices between stroke onset and at 2, 4, and 8 weeks after stroke, i.e., ΔSMI, Δparalyzed lower limb muscle mass, and Δnon-paralyzed lower limb muscle mass, were calculated and the changes in each index over time were compared between the two groups. [Results] The analyses did not reveal any significant intergroup differences. [Conclusion] Even in cases of severe paralysis, appropriate nutritional and exercise therapies may help maintain the muscle mass.
[目的] 根据运动功能障碍的严重程度比较中风后骨骼肌质量的变化。[参与者与方法] 本研究纳入了17例中风患者。根据下肢Brunnstrom分期将患者分为两组，即处于III期和IV期的患者（中度运动功能障碍组；n = 9），以及处于V期和VI期的患者（轻度运动功能障碍组；n = 8）。在以下时间点测量肌肉质量：中风发作后3天内；中风发作后2周±2天；中风发作后4周±2天；中风发作后8周±2天，并评估肌肉质量指数，即骨骼肌质量指数（SMI）、瘫痪下肢肌肉质量和非瘫痪下肢肌肉质量。计算中风发作与中风后2、4和8周时这些肌肉质量指数的变化，即ΔSMI、Δ瘫痪下肢肌肉质量和Δ非瘫痪下肢肌肉质量，并比较两组中各指数随时间的变化。[结果] 分析未发现任何显著的组间差异。[结论] 即使在严重瘫痪的情况下，适当的营养和运动疗法可能有助于维持肌肉质量。
