Objective:To measure the electromyographic values of pelvic floor muscle surface via electrophysiological examination after treatment with scalp acupuncture combined with“four sacral needles” therapy,and provide objective evidence for the clinical effect of acupuncture for female stress urinary incontinence(SUI).Methods:Selected 62 cases of patients with female SUI, and divided them into two groups randomly, 32 cases in the study group and 30 cases in the control group.The control group received biofeedback electric stimulation therapy combined with Kegel exercises,while the study group additionally received scalp acupuncture combined with four sacral needles therapy.The treatment of both groups lasted for 4 weeks.After treatment, compared the electromyographic values of pelvic floor muscle surface, urinary incontinence volume in 1-hour pad test and scores of ICI-Q-SF in both groups.Results:Before treatment,comparing the electromyographic values of pelvic floor muscle surface in both groups,there was no significant difference being found(P >0.05).After treatment,the electromyographic values of pelvic floor muscle surface in both groups were higher than those before treatment,and the electromyographic values of pelvic floor muscle surface in the study group were higher than those in the control group,differences being significant(P < 0.05).Before treatment,comparing the urinary incontinence volume in 1-hour pad test in both groups,there was no significant difference being found(P > 0.05).After treatment,the urinary incontinence volume in 1-hour pad test in both groups was lower than that before treatment,and the urinary incontinence volume in 1-hour pad test in the study group was lower than that in the control group,differences being significant(P<0.05).Before treatment,comparing the scores of ICI-Q-SF in both groups,there was no significant difference being found(P >0.05).After treatment,the scores of ICI-Q-SF in both groups were lower than those before treatment,and scores of ICI-Q-SF in the study group were lower than those in the control group,differences being significant(P<0.05).Conclusion:The additional application of scalp acupuncture combined with“four sacral needles” therapy based on biofeedback electric stimulation therapy combined with Kegel exercises has significantly better clinical effect than the simple application of biofeedback electric stimulation therapy combined with Kegel exercises in treating female SUI.It indicates that scalp acupuncture combined with four sacral needles therapy has exact effect in treating SUI,which is worthy of clinical promotion and application.
