Observe and Analyze the Rehabilitation of Multiparous Pelvic Floor Muscles in Postpartum / 实用妇产科杂志

ABSTRACT

Objective:To analyze the effects of mutiparity on the pelvic floor muscle and the best time of postpartum for pelvic floor rehabilitation intervention.Methods:By questionnaire survey and pelvic floor functional checking on women with 42 days postpartum clinic routine health checking,and following up pelvic floor muscles force exam in postpartum 3 months,6 months and 1 year,426 cases were included in the puerpera group,including primipara 325 cases as primiparous group,two birth multipara 101 cases as multiparous group,the damage of pelvic floor muscles(≤level Ⅱ) was compared between the two groups,the difference between multiparity and primiparity were compared.Results:①In postpartum 42 days,type Ⅰ muscle fiber damage rate was lower in multiparous group than that in primiparous group(P ＜0.05),there was no significant difference on the muscle fiber damage ratio (muscles force below Ⅲ) between the two groups (P ＞ 0.05).②)In postpartum 3 months,6 months,1 year there was no significant difference in proportion of muscle damage between the two groups (P ＞ 0.05).③Multiparous group pelvic floor muscle damage ratio decreased slowly and gradually in the four periods,there was no statistical difference between adjacent period (P ＞ 0.05),the pelvic muscle damage ratio appeared significant statistical difference between postpartum 6 months and postpartum 42 days(P ＜ 0.01).④In primiparous group,pelvic floor muscle damage ratio decreased significantly in postpartum 6 months,postpartum 42 days、3 months,6 months,the differces were statistically significant among the three times(P ＜ 0.05),there was no statistical difference between postpartum 6 months and 1 year(P＞0.05).Conclusions:Type Ⅰ muscle fibers suffer injury more in Primipara than that in multipara,multiparous pelvic floor muscle recovery process is more slowly than primipara's,we should pay attention to pelvic muscle recovery within 6 months after delivery.
