脑卒中偏瘫患者上肢肌肉功能表面肌电图评价

Surface electromyographic evaluation of upper limb muscle function in stroke patients with hemiplegia

目的观察脑卒中后偏瘫患者的患侧上肢前屈过程中相关肌肉表面肌电特征。方法选取16例符合纳入排除标准偏瘫患者和16例对照组受试者,所有观察组患者均进行患侧肢体的表面肌电图测试以及Fugl-Meyer上肢功能评定,对照组患者则采取右侧肢体作为对照,采集相应表面肌电值。结果观察组患者的斜方肌、三角肌前束、肱二头肌、肱三头肌的表面肌电值均高于对照组,差异均有统计学意义(t分别=2.29、4.64、3.97、2.94,P均<0.05)。观察组患者患侧上肢Fugl-Meyer评分平均(25.38±14.06)分,与患侧上肢动作完成过程中斜方肌、三角肌前束、肱二头肌、肱三头肌的表面肌电值无明显相关性(r分别=0.31、0.28、0.48、0.43,P均>0.05)。结论作为一种客观、量化的评估手段,表面肌电图是单一动作执行能力的有效评估工具。

Objective To investigate the characteristics of muscle surface electromyography（s EMG） in the upper limb flexion of stroke patients with hemiplegic. Methods Totally 16 cases patients met the inclusion criteria and 16 cases in control group were selected. All patients in the observation group were performed the surface electromyographic test of the affected side and upper limb Fugl-Meyer assessment. The control group was also performed the surface electromyographic test of the right limb for control. Results The observation group has higher s EMG of the trapezius,deltoid,biceps,and the triceps brachii muscle than control group,the differences were statistically significant（t=2.29,4.64,3.97,2.94,P〈0.05）. The upper limb Fugl-Meyer score of observation group was 25.38±14.06,which was not significantly correlated with the s EMG of the trapezi us,deltoid,biceps,and triceps brachii muscle respectively（r=0.31,0.28,0.48,0.43,P〉0.05）. Conclusion s EMG is an effective tool to evaluate the performance of motor task for stroke patient as an objective and quantitative assessment method.
