摘要
目的:应用表面肌电描记术(sEMG)来研究偏瘫患者和正常人在日常生活活动(ADL)中的上肢相关肌肉表面肌电特点。方法:应用Megawin表面肌电系统来采集15例正常人(正常组)和10例偏瘫患者(偏瘫组)在执行抬臂、梳头、喝水、摸对侧肩、摸后口袋这5项ADL时的上肢相关肌肉表面肌电信号。经信号处理得到肱二头肌、肱三头肌、三角肌前部、三角肌中部、三角肌后部、前锯肌、背阔肌、斜方肌上部、斜方肌下部的均方根(RMS)比值,并分析正常组和偏瘫组上肢相关肌肉RMS比值异同。结果:偏瘫组较正常组肱三头肌、三角肌前部、三角肌中部、三角肌后部、前锯肌和斜方肌下部RMS比值显著增大(P<0.05)。结论:偏瘫患者可采用与正常人不同的肌肉收缩策略来完成ADL。
Objective：To study the surface electromyography （sEMG） features of normal subjects and hemiplegic patients in 5 kinds of activities of daily living （ADL）. Method：Megawin sEMG system was used to record the sEMG data of 15 normal subjects（normal group） and 10 hemiparetic patients（hemiplegic group） during performing 5 kinds of ADLs. The tasks were reaching up, combing, drinking, touching lateral shoulder and touching back pocket. After managing, the root-mean-square （RMS） ratios of biceps brachii muscle, triceps brachii muscle, anterior part of deltoid muscle, median part of deltoid muscle, lateral part of deltoid muscle, serratus anterior muscle, latissimus dorsi muscle, upper part of trapezius muscle and lower part of trapezius muscle were obtained. And then, the RMS ratios in normal group and hemiplegic group were compared. Result： The RMS ratios of hemiplegic group increased significantly in triceps hrachii, anterior part of deltoid muscle, median part of deltoid muscle, laterior part of deltoid muscle, serratus anterior muscle and lower part of trapezius muscle（P〈0.05）. Conclusion： The hemiplegic patients may utilize different from healthy subjects＇ muscle contraction strategies to perform ADL.
