脑卒中患者身体功能下降，以康复为目标。在亚急性期改善其功能是很重要的。能站立的偏瘫患者与健康人相比，在质心和肌肉协同作用等方面表现出不同的特征。然而，在亚急性期，坐立运动所达到的特征是未知的。本研究调查了偏瘫患者（n = 21）在中风发作3个月内的坐立运动。根据出院时的功能独立性评分将患者分为“轻度”和“重度”两组，并通过肌肉协同和运动学分析患者在亚急性期的坐立运动。重度患者偏向非麻痹侧站立，有利于全身伸展的肌肉协同作用激活时间早于轻度患者。这项研究有助于制定针对每位患者的最佳干预指南。
Patients with stroke experience declined physical functions and aim to recover by rehabilitation. It is important to improve their functions in the subacute period. Hemiplegic patients who can stand exhibit differing characteristics such as the center of mass and muscle synergy compared to healthy subjects. However, the characteristics to be achieved by the sit-to-stand motion in the subacute period is unknown. This study investigated the sit-to-stand motions of hemiplegic patients (n = 21) in three months of stroke onset. The patients were partitioned into two groups ('mild' and 'severe'), based on the functional independence score at the time of discharge, and the patient's sit-to-stand motion in the subacute period was analyzed by muscle synergy and kinematics. The severe patients performed a biased standing on the non-paralyzed side, and the activation timing of muscle synergy that contributes to whole-body extension was earlier than that of the mild patients. This study contributes to the development of guidelines for optimal intervention for each patient.
