摘　　要：目的通过表面肌电信号相关特征值的提取和分析,建立基于表面肌电信号的脑卒中患者躯干肌运动功能评定的新方法,客观评价分析中枢神经损伤后躯干肌的运动功能以及针灸电刺激对其运动功能重建的疗效。方法选取坐位平衡在Ⅱ级以上(无支持能坐,体质量能很好地前移且分配均匀)的脑卒中患者22例,随机分为两组,治疗组A(常规康复组),治疗组B(常规康复加针灸治疗组)。从患者家属中选取11例正常受试者作为对照组,采集三组躯干前倾时主动肌(骶棘肌)肌电信号的最大值(MAX)、均方根值(RMS)。结果治疗前骶棘肌在偏瘫侧与非偏瘫侧的MAX、RMS比较,均P<0.05,治疗组A、B治疗后均有疗效,且治疗组A、B之间差异有统计学意义。结论重度脑卒中患者一侧偏瘫,躯干肌双侧力量均下降。常规训练加上针灸电刺激腰部夹脊穴法,可提高偏瘫患者康复效果。Objective To establish a new method based on sEMG of the trunk muscle motor function in stroke patients for the objective evaluation and analysis of central nervous system injury trunk muscle motor function by the sEMG signal associated eigen value extraction and analysis,and evaluate the efficiency for reconstruction of trunk muscle exercise with electrical stimulation of acupuncture methods.Methods 11 normal subjects as control group were selected,the 22 cases of stroke patients with setting balance level and above（no support to be able to sit well forward and the weight can be evenly distributed ）were randomly divided two groups：conventional rehabilitation（Group A）and conventional rehabilitation and acupuncture treatment group（Group B）.Active muscles（sacral spine muscles）maximum（MAX）and root mean square value（RMS）when the trunk forward were collected.Results Before the treatment,the MAX and RMS of sacral spine muscles electrical signal in hemiplegia side were lower than those in non-hemiplegiaside,P0.05,them all improved significantly in both group A and group B after the treatment,but which were better in group B,P0.05.Conclusions The strength of bilateral trunk muscles all decreased in patients with severe stroke and hemiplegia,which can be improved by conventional electrical stimulations combined with waist Jiaji acupancture.
