摘　　要：目的通过对阴道分娩后6~8周盆底表面肌电信号的检测和分析,探讨不同阴道分娩方式下女性盆底表面肌电特征,评价其对女性盆底功能障碍(FPFD)的预测、诊断方面的临床意义。方法选择2019年在我院进行产后6~8周盆底表面肌电检测产妇的数据进行分析。结果阴道分娩后6~8周盆底表面肌电值异常发生率前3位的依次为:慢肌阶段平均值、快肌阶段最大值、前静息阶段平均值。无痛结合无保护会阴分娩会阴撕伤组与无痛分娩会阴侧切组慢肌阶段腹肌参与平均值差异有统计学意义(P<0.05)。结论阴道分娩后6~8周盆底肌电分析提示:盆底动态肌电活动下降发生率最高、其次为静息肌电活动增高。因存在腹肌等协同肌参与盆底肌代偿情况,不同阴道分娩方式对盆底肌肌力影响是否有差异尚不能定论,而不同阴道分娩方式对盆底肌张力影响无明显差异。盆底表面肌电检测过程中应尽量控制腹肌等协同肌的参与。Objective To investigate the characteristics of women′s pelvic floor surface electromyography(PEMG)in different vaginal delivery modes,and evaluate its clinical significance in the prediction and diagnosis of pelvic floor dyssynergia(FPFD),through detecting and analyzing of the PEMG signals at 6-8 weeks after vaginal delivery.Methods The data of parturients who received PEMG for 6-8 weeks after delivery in 2019 in our hospital were selected for analysis.Results The top three abnormal incidence rates of PEMG at 6-8 weeks after vaginal delivery were the average value of slow muscle stage,the maximum value of fast muscle stage and the average value of pre-resting stage.There was a significant difference in the average participation of abdominal muscles in the slow muscle stage between the perineal laceration group and the perineal lateral incision group(P<0.05).Conclusion The analysis of PEMG at 6-8 weeks after vaginal delivery showed that the incidence of decreased pelvic floor dynamic electromyography was the highest,followed by increased resting electromyography.Due to the fact that abdominal muscles and other synergic muscles participate in pelvic floor muscle compensation,it is still uncertain whether different vaginal delivery methods have different effects on pelvic floor muscle strength,while different vaginal delivery methods have no significant difference on pelvic floor muscle tension.The participation of abdominal muscles and other synergic muscles should be controlled as much as possible in the detection of PEMG.
