Short-term Effect of Pelvic Floor Rehabilitation Therapy on the Pelvic Floor Muscle Strength in the Early Postpartum of Women

Objective:To observe the short-term effect of electric stimulation-biofeedback pelvic floor rehabilitation therapy on the pelvic floor muscle strength for the women with different delivery modes in the early postpartum.Methods:The 200 pregnant women who had their childbirth in this hospital during May 2009 to May 2010 were selected and were allocated into two groups,treatment group and control group,each group have both selective caesarean section(50 cases)and vaginal delivery(50 cases).Treatment group conduct pelvic floor rehabilitation therapy.In 6-7 weeks and 5-6 months after childbirth,biofeedback electrical stimulation device was used to evaluate pelvic floor muscle strength.Results:There are 200 pregnant women get into the study,171 cases in which have accomplish the detection 6 months after childbirth.After electric stimulation-biofeedback pelvic floor rehabilitation therapy,the EMG activity value of pelvic floor typeⅠ,Ⅱ muscle fiber in treatment group is better than control group in puerpera of vaginal delivery,have significant difference between the two groups(P0.001).In puerpera of caesarean section,the contraction strength of typeⅠ,Ⅱ muscle fiber and contraction time of typeⅡA muscle fiber in treatment group is better than control group,have significant difference between the two groups(P 0.001).Whatever any delivery pattern,followed up in 6 months after childbirth,the pelvic floor muscle strength in pelvic floor rehabilitation therapy group is better than the control group,especially for the vaginal delivery group.Conclusions: Whatever any delivery pattern,the function of pelvic floor muscles recover after pelvic floor electric stimulation-biofeedback rehabilitation therapy in the early postpartum,especially for vaginal delivery.
