Abstract: Objective：To analysis of the effect of pelvic muscle training （biofeedback，electrical stimulation，rehabilitation exercise） in early postpartum pelvic floor dysfunction. Methods：236 cases in 42 days after childbirth in the Second Affiliated Hospital of Zhengzhou University in 2010 December to 2011 June in department of gynecology and obstetrics，were randomly divided into treatment group（n=78） or dumbbell group（n=78） or control group（n=80）. The treatment group received biofeedback，electrical stimulation and vaginal rehabilitation exercise，the dumbbell group received rehabilitation exercise，the control group received postpartum health education. Three groups at 3 months postpartum，6 months were finished with pelvic floor muscle testing，epidemiological survey，ICIQ-SF，POP-Q index. Results：The treatment group was better than that of pelvic floor muscle strength recorvery dumbbell，dumbbell set of pelvic floor muscle strength recorvery better than the control group. In 3 months postpartum，pelvic floor muscle fiber treatment group class I，class II muscle fiber fatigue were lower than the control group，and treatment group class I，class II muscle fiber voltage were higher than the control group （P＜0.05）. In 3 months and 6 months
postpartum， the incidence rate of SUI in the treatment group and dumbbell group were lower than those of the control group，the differences were statistically significant（P＜0.05）. In 3 months postpartum，the incidence rate of S+P has no statistical significance in three groups（P＞0.05），and in 6 months postpartum， the incidence rate of S+P in the treatment group were lower than that of the dumbbell group and the control group， the differences were statistically significant（P＜0.05）. Conclusions：Postpartum pelvic floor muscle rehabilitation training is an effective method to improve the pelvic floor muscle，which can effectively reduce the incidence of SUI and POP.
