摘    要:目的 探讨表面肌电检测技术在腰椎间盘突出症中的临床应用.方法 腰椎间盘突出症患者44例,按照腰痛视觉模拟评分(VAS)分为轻度疼痛组(A组)和中重度疼痛组(B组),分别采集两组患者在完成自身重量的腰部竖脊肌等长负荷测试和踝跖屈最大角度自身重量的腓肠肌等长负荷测试时健、患侧L5~S1水平竖脊肌和腓肠肌内侧头的表面肌电信号,分析平均肌电值(AEMG)和中位频率的斜率(MFs).结果两组患者患侧腰部竖脊肌和腓肠肌内侧头AEMG较健侧均有降低(P<0.05),患侧MFs绝对值较健侧升高(P<0.05); 组间比较,B组患侧两组肌肉MFs绝对值均较A组增大 (P<0.05);B组健/患侧肌肉AEMG比均大于A组(P<0.05),但MFs比均未见显著性差异(P>0.05).结论 表面肌电图可以作为一种无创检测腰椎间盘突出症腰部和下肢神经肌肉功能状态的工具;踝跖屈最大角度自身重量的腓肠肌等长负荷测试可以作为评价腰椎间盘突出症患者下肢神经肌肉功能状态的方法 之一;腰椎间盘突出症患者腰部主观疼痛感程度不同时,双侧腰部竖脊肌和腓肠肌表面肌电信号的失衡程度也不同.

关 键 词:腰椎间盘突出症  表面肌电图(sEMG)  视觉模拟评分(VAS)  功能评定  平均肌电值(AEMG)  中位频率的斜率(MFs)

Abstract:Objective To investigate the application of surface electromyography (sEMG) in patients with lumbar disc herniation.Methods 44 patients with chronic lumbar disc herniation were divided into mild pain group (group A) and moderate to severe pain group (group B) according to their scores of Visual Analogue Scale (VAS).Their sEMG at erector spinae and gastrocnemius were collected,and the average EMG (AEMG),slope of median frequency (MFs) were analyzed.Results Compared with those in the healthy side,AEMG of erec...
Keywords:lumbar disc herniation  surface electromyography (sEMG)  Visual Analogue Scale (VAS)  functional assessment  average EMG (AEMG)  slope of median frequency (MFs)
