Stroke patients often use various arm slings, but the effects of different slings on the joint kinematics and muscle activity of the arm in the gait have not been investigated. The effects of joint kinematics and muscle activity in the gait were investigated to provide suggestions for gait training for stroke patients. In all, 10 chronic stroke patients were voluntarily recruited. An eight-camera three-dimensional motion analysis system was used to measure joint kinematics while walking; simultaneously, electromyography data were collected for the anterior and posterior deltoids and latissimus dorsi. The amplitude of pelvic rotation on the less-affected side differed significantly among the different arm slings (<0.05). Changes in the knee kinematics of the less-affected side also differed significantly (<0.05), while there were no significant differences in the muscle activity of the affected arm. In stroke patients, an extended arm sling is more useful than no sling or a flexed arm sling in terms of the amplitude of the rotation of the less-affected pelvic side in the stance phase while walking. The less-affected knee joint is flexed more without a sling than with any sling. All arm slings support the extension of the contralateral knee.
中风患者经常使用各种手臂吊带，但不同吊带对步态中手臂关节运动学和肌肉活动的影响尚未得到研究。本研究旨在探究步态中关节运动学和肌肉活动的影响，为中风患者的步态训练提供建议。总共自愿招募了10名慢性中风患者。使用八摄像头三维运动分析系统在行走时测量关节运动学；同时，收集三角肌前后束和背阔肌的肌电图数据。不同手臂吊带之间，患侧骨盆旋转幅度差异显著（<0.05）。患侧膝关节运动学变化也有显著差异（<0.05），而患侧手臂的肌肉活动没有显著差异。对于中风患者，在行走站立期，就患侧骨盆旋转幅度而言，伸展型手臂吊带比不使用吊带或屈曲型手臂吊带更有用。不使用吊带时，患侧膝关节比使用任何吊带时屈曲程度更大。所有手臂吊带均有助于对侧膝关节伸展。
