【摘要】：目的 :研究脑卒中患者最大等长收缩(maximum isometric voluntary contraction,MIVC)运动中肱二头肌和肱桡肌表面肌电特征,为脑卒中上肢康复治疗提供电生理学依据。方法:选取脑卒中后偏瘫患者15例,通过表面肌电采集患侧和健侧MIVC运动中肱二头肌和肱桡肌的表面肌电均方根值(root mean square,RMS),并对患侧和健侧肱二头肌和肱桡肌间的RMS值(平均值和最大值)分别进行对比分析。结果:患侧肱二头肌和肱桡肌MIVC运动中测得的RMS平均值和最大值均明显低于健侧,差异有统计学意义(P0.001)。患侧和健侧MIVC运动中肱二头肌的RMS值平均值和最大值均明显高于肱桡肌,差异有统计学意义(P0.001)。结论:脑卒中可导致其患侧MIVC时运动单位募集能力下降。肱二头肌在屈肘肌MIVC运动中发挥主导作用。
[Abstract]:Objective: to study the electromyography characteristics of biceps brachii and brachioradialis during maximum isometric voluntary contractility exercise in stroke patients, and to provide electrophysiological basis for rehabilitation therapy of upper limbs in stroke. Methods: fifteen patients with hemiplegia after stroke were selected. Surface electromyography (EMG) of biceps brachii and brachioradialis muscle were collected by surface electromyography (EMG). The mean value and maximum value of RMS (mean value and maximum value) of biceps brachii and brachioradialis muscle were compared between the affected and healthy sides of biceps brachialis and brachioradialis muscle. Results: the average value and maximum value of RMS measured in biceps brachii muscle and brachioradialis muscle during MIVC exercise were significantly lower than those in the normal side (P 0.001). The average value and maximum value of RMS of biceps brachii during MIVC exercise in the affected and healthy sides were significantly higher than those in the brachioradialis muscle (P 0.001). Conclusion: stroke may lead to a decrease in the recruitment ability of motor units in the affected side of MIVC. Biceps brachii play a leading role in the MIVC movement of elbow flexion.
