Objective To investigate the effect of perineal body massage combined with biofeedback elec⁃ trical stimulation on the recovery of pelvic floor nerve tissue function and sexual function in puerpera. Methods 200 pregnant women were randomly divided into a control group and a study group with 100 in each one. The control group received routine health education and guidance during pregnancy，as well as postpartum diet and pelvic floor muscle exercise；on the basis of the control group，the study group received massage of the perineum at 35 weeks of gestation and biofeedback electrical stimulation at 6 weeks after delivery. The delivery outcome，perineal lacera⁃ tion degree，lateral incision rate，pelvic floor muscle strength and sexual function recovery at 3 and 6 months after delivery were observed in the two groups. The effect of perineal body massage combined with postnatal biofeedback electrical stimulation on pelvic floor function and sexual function recovery in the third trimester of pregnancy was evaluated. Results There were significant differences in perineal laceration，lateral incision rate，and rate of lateral incision and midwifery between the two groups（Z = 3.45；χ2 = 20.88；P < 0.01）；There were significant differences in pelvic floor organ prolapse（POP⁃Q scale），pelvic floor muscle strength score，EMG value and sexual function 3 months following childbirth（H = 35.07；F = 8.43；P < 0.01）. In the control group，there were no significant differences in pelvic floor function and sexual function between the woman receiving Cesarean section and those with normal delivery at 3 months after delivery（P = 0.84），but there was a significant difference as compared with lateral incision/lateral incision and midwifery group（P < 0.05 or P < 0.01）. The rank correlation and single factor regression analysis showed the muscle strength of class Ⅱ muscle fibers was positively correlated with the total FSFI score on sexual function（r = 0.69，P < 0.01）. Conclusions Perineal body massage in the third trimester of pregnancy can effectively reduce the rate of lateral incision and midwifery and degree of perineal laceration during vaginal delivery. This procedure combined with postpartum biofeedback electrical stimulation can effectively accel⁃ erate the recovery of pelvic floor nerve tissue function and sexual function.
