Abstract

Abstract:

Objective To explore the effect of core muscle stability training combined with biofeedback electrical stimulation on pelvic floor muscle function in postpartum women underwent episiotomy. Methods Clinical data of 98 parturients who underwent selective episiotomy during natural childbirth were retrospectively analyzed. According to different intervention methods, the included parturients were divided into the control group and the combination group, with 49 cases in each group. The control group was treated only with biofeedback electrical stimulation therapy, while the combination group was treated with core muscle stability training combined with biofeedback electrical stimulation therapy. The general information and pelvic floor muscle strength, pelvic floor electromyography values, pelvic floor dysfunction questionnaire (PFDI-20) scores and female sexual function score scale (FSFI) scores were compared between the two groups of parturients before and after intervention. Results There were no significant differences in age, gestational age, body mass index and pelvic floor muscle strength grading between the two groups (P>0.05). Compared with before intervention, pelvic floor muscle strength, pelvic floor electromyography values and FSFI scores increased in both groups after intervention, while PFDI-20 scores decreased (all P<0.05). After intervention, compared with the control group, the combination group showed more significant improvement in pelvic floor muscle strength, with an increase in class Ⅰ and class Ⅱ fiber electromyography values, a decrease in PFDI-20 score, and an increase in FSFI scores (all P<0.05). The incidence of pelvic floor dysfunction in the two groups was statistically significant (22.45% vs.6.12%, P<0.05). Conclusion Core muscle stability training combined with biofeedback electrical stimulation can effectively promote the recovery of pelvic floor muscle function and improve sexual function in postpartum women underwent episiotomy.
