| 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 hemiplegia after brain lesion.Methods 37 hemiplegics were assessed the elbow spasticity with MAS by a same therapist.Their sEMG of BB and TB 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 during passive movements of both elbow flexion and extension,which may help for the spasticity assessment. |
