本研究的目的是描述偏瘫患者患侧上肢肌肉收缩开始和终止的延迟与运动障碍和肢体残疾的临床测量之间的关系。记录了26例中风长期存活者在等长屈腕和伸腕时的肌电活动。分别采用Fugl-Meyer运动功能评定(FMA)和上臂运动能力测试(AMAT)评定上肢运动功能障碍和残疾。瘫痪手臂肌肉收缩开始和终止的延迟时间明显延长。然而，中风类型、中风程度、偏瘫的一侧或存在失语症对延迟没有显著影响。肌肉收缩的开始和终止延迟与FMA和AMAT显著相关。肌肉收缩开始和终止的异常延迟可能导致偏瘫患者的上肢运动障碍和身体残疾。(C)2002年威利期刊公司。
The purpose of this study was to describe the relationship between the delay in initiation and termination of muscle contraction and clinical measures of motor impairment and physical disability in the affected upper limb of patients with hemiparesis. Electromyographic (EMG) activity of 26 long-term survivors of stroke was recorded during isometric wrist flexion and extension. Upper limb motor impairment and disability were assessed with the Fugl-Meyer motor assessment (FMA) and arm motor ability test (AMAT), respectively. Delay in initiation and termination of muscle contraction was significantly prolonged in the paretic arm. However, the delay was not significantly affected by stroke type, stroke level, side of hemiparesis, or presence of aphasia. Delay in initiation and termination of muscle contraction correlated significantly with FMA and AMAT. Abnormally delayed initiation and termination of muscle contraction may contribute to hemiparetic upper limb motor impairment and physical disability in hemiparetic patients.
