摘要
目的:探讨受试者工作曲线(receiver operatingcharacteristic curve,ROC)评价盆底表面肌电对功能性肛门直肠痛的临床诊断价值.方法:对同期118例功能性肛门直肠痛患者和103例无症状人群采用Glazer盆底表面肌电评估方法采集表面肌电值,包括波幅、变异系数、反应时间和中值频率.绘制ROC曲线,对表面肌电值诊断功能性肛门直肠痛的准确性进行评价.结果:功能性肛门直肠痛患者在持续收缩阶段的收缩波幅明显小于无症状组(23.81±13.75 vs 30.55±16.14,P<0.05),持续收缩阶段的变异系数明显大于无症状组(0.43±0.12 vs0.30±0.07,P<0.05),耐久收缩阶段的变异系数也大于无症状组(0.40±0.15 vs 0.28±0.09P<0.05).ROC曲线显示,持续收缩和耐久收缩阶段的变异系数诊断临界值分别为0.35和0.31,曲线下面积分别为0.813和0.761.结论:收缩阶段的变异系数对功能性肛门直肠痛有较好的临床诊断价值.
AIM： To assess the diagnostic value of pelvic floor surface electromyography （sEMG） in functional anorectal pain （FARP） using receiver operating characteristic （ROC） curve analysis. METHODS： The parameters of pelvic floor sEMG in 118 patients with FARP and 103 norlnal controis were measured according to the Glazer protocol. Parameters included amplitude （AVG）, co- efficient of variance （CV）, onset time and median frequency （MF）. The ROC curve was plotted to assess the diagnostic value of pelvic floor sEMG.RESULTS： Compared with the control group, the FARP group had a lower AVG （23.81 ± 13.75 vs 30.55 ± 16.14, P 〈 0.05） and a higher CV （0.43 ± 0.12 vs 0.30 ± 0.07, P 〈 0.05） during the tonic phase and a higher CV during the endurance phase （0.40 ± 0.15 vs 0.28 ± 0.09, P 〈 0.05）. The critical value of CV during the tonic and endurance phases were 0.35 and 0.31, respectively, and the areas under ROC curve were 0.813 and 0.761. CONCLUSION： CV during the tonic and endurance phases has better diagnostic value in FARP.
