目的：全局联动被定义为偏瘫患者在自主运动期间触发的受累侧无目的相关运动。本研究的目的是用静态双关节测力仪和肌电图来描述偏瘫受试者在未受影响的一侧最大程度渐进握力时上肢整体联动性的强度和模式。设计：调查，方便样本，设置：大学二级保健康复中心，数据集：用Fugl-Meyer评估法评估的重度（n = 8）和中度（n = 7）运动表现缺陷患者的整体联动性、扭矩和肌电活动，并与健康受试者组（n = Ii）进行比较。临床上，重度缺陷组患者肘关节痉挛程度高于中度缺陷组，肘关节力量下降。结果：方差分析的结果显示，在严重缺陷的受试者中，随着对侧握握时用力的增加，屈曲和内旋时肩扭矩和屈曲时肘关节扭矩显著增加(p
Objective: Global synkineses are defined as nonpurposive associated movements on the involved side of hemiparetic subjects that are triggered during a voluntary movement. The purpose of this study was to characterize the intensity and pattern of upper limb global synkineses in hemiparetic subjects with a static biarticular dynamometer and electromyography during maximal progressive hand grip on the unaffected side.Design: Survey, convenience sample,Settings: University secondary care rehabilitation center,Data Set: Global synkineses tie, torques and electromyographic activities) in patients with severe (n = 8) and moderate (n = 7) deficits in motor performance, as evaluated by the Fugl-Meyer assessment, were compared with those obtained in a group of healthy subjects (n = Ii). Clinically the subjects from the severe deficit group were more spastic and snowed less strength at the elbow than the subjects from the moderate deficit group.Results: Results of analyses of variance showed significant increases of shoulder torque in flexion and internal rotation, and elbow torque in flexion, with increasing force exertion during contralateral hand grip in subjects with severe deficits (p
