Abstract：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.
