目的：探讨ROC曲线评价盆底表面肌电对盆底失弛缓综合征的临床诊断价值。方法：采用Glazer盆底表面肌电评估方案对90例盆底失弛缓患者（盆底失弛缓组）和101例无症状人群（无症状组）采集表面肌电值，检测指标包括波幅、变异系数、反应时间和中值频率，并绘制ROC曲线。结果：盆底失弛缓组患者前基线静息波幅大于无症状组（P＜0．05）；快速收缩和持续收缩阶段收缩波幅小于无症状组（P＜0．05）；持续收缩和耐久收缩阶段变异系数明显大于无症状组（P＜0．05）；持续收缩阶段变异系数ROC 曲线下面积为0．883，临界值为0．355，灵敏度和特异度分别为88．4％和71．1％；耐久收缩阶段变异系数ROC 曲线下面积为0．825，临界值为0．305，灵敏度和特异度分别为84．9％和67．8％。结论：持续收缩和耐久收缩阶段的变异系数可以作为盆底失弛缓综合征有价值的临床诊断指标。

Objective To evaluate the clinical diagnostic value of pelvic floor sEMG in pelvic floor dyssynergia (PFD) by using receiver operating characteristic curve (ROC curve). Methods The pelvic floor sEMG of 90 patients with PFD and 101normal controls were determined by the Glazer protocol.Parameters including amplitude (AVG),coefficient of variance (CV),onset time and median frequency (MF),and the ROC curve werealso investigated. Results Compared to the control group,the PFD group had a higher AVG of pre-baseline (P < 0.05), a lower AVG during Flick and Tonic steps(P < 0.05), and ahigher CV duringTonic and Endurance steps(P < 0.05).The area under curve(AUC) of CV duringthe tonic step was 0.883 withthe best cut-off of 0.355, and with sensitivity of 88.4%and the specificity of 71.1%, respectively; The AUC of CV duringEndurance step was 0.825 withthe best cut-off of 0.305, and with the sensitivity of 84.9%and the specificity of 67.8% , respectively. Conclusion The CVs of the tonic and the endrnace phases can be used as valuable clinical values in diagnosis of PFD.
