ObjectiveTo investigate the effect of electrical stimulation combined with biofeedback and pelvic floor muscle training in the prevention of female pelvic floor dysfunction.MethodsFrom June 2015 to June 2016,350 cases of puerperae who received treatment in our hospital were selected as research subjects.According to the different training methods of pelvic floor muscle,all the subjects were divided into treatment group and control group.210 cases in the treatment group were given electrical stimulation combined with biofeedback therapy 6 weeks after delivery;140 cases in the control group performed pelvic floor muscle training themselves at home.Relevant clinical data of 6 weeks,6 months and 1 year after delivery of two groups were recorded and compared,including pelvic floor electrophysiological parameters,POP-Q indexs,PFIQ-7 scores and PISQ-12 scores.ResultsThe ratios of muscle strength levelⅢor above of gradeⅠmuscle fibers and gradeⅡmuscle fibers in two groups were significantly improved in 6 months and 1 year after the delivery,and the improvement in the treatment group was higher than the control group.The differences between the two groups were statistically significant(P＜0.05).The electrophysiological parameters of pelvic floor were compared between the two groups of puerpera 6 months and 1 year after the delivery.The improvement of other pelvic floor electrophysiological parameters in the treatment group were significantly better than that in the control group,and the differences between the two groups were statistically significant(P＜0.05).The improvement of POP-Q indexing Aa indication point in the treatment group was better than that of the control group in 6 months and 1 year after the delivery,and the differences were statistically significant(P＜0.05),while there were no significant differences in other indication points between the two groups(P＞0.05).The PFIQ-7 scores and PISQ-12 scores were compared between the two groups,and the differences were not statistically significant(P＞0.05).ConclusionElectrical stimulation combined with biofeedback therapy and other pelvic floor muscle training have the effect of improving the electrophysiological parameters of pelvic floor,which has a significant effect in the prevention female pelvic floor dysfunction,and is worthy of promotion and application.
