摘要： 目的探索肱二头肌、肱三头肌表面肌电(sEMG)特征与偏瘫患者肘关节肌张力的关系。方法同一治疗师对37 例脑损伤后偏瘫患者的患侧肘关节进行改良Ashworth 量表(MAS)评估，同时用sEMG记录被动活动时肱二头肌和肱三头肌的表面肌电信号。结果经Spearman 相关分析，被动屈肘时，肱二头肌(r=0.651)、肱三头肌(r=0.912)、肱三头肌+肱二头肌(r=0.905)、肱三头肌-肱二头肌(r=0.903)的均方根值(RMS)与MAS 相关(P<0.001)；被动伸肘时，肱二头肌(r=0.848)、肱三头肌(r=0.518)、肱三头肌+肱二头肌(r=0.850)、肱二头肌-肱三头肌(r=0.711)的RMS 与MAS 相关(P<0.001)。结论sEMG 能检测主动肌和拮抗肌的肌电活动，对临床肌张力评估和痉挛的治疗提供量化的参考。

Abstract: Objective To explore the correlation between characteristics of surface electromyography (sEMG) from biceps brachii (BB)and triceps brachii (TB) and the Modified Ashworth Scale (MAS) during a passive movement of the spastic elbow in patients with hemiplegiaafter brain lesion. Methods 37 hemiplegics were assessed the elbow spasticity with MAS by a same therapist. Their sEMG of BB andTB were recorded synchronously. Results The Spearman analysis showed that the root mean square (RMS) of sEMG from BB (r=0.651),TB (r=0.912), TB+BB (r=0.905), TB-BB (r=0.903) correlated with MAS (P<0.001) when elbows were flexed, as well as elbows were extended(r=0.848, r=0.518, r=0.850, r=0.711, P<0.001). Conclusion sEMG can present the electrical activities of agonist and antagonist duringpassive movements of both elbow flexion and extension, which may help for the spasticity assessment.
