Abstract:Objective To study the effects of pelvic floor rehabilitation training on the prevention and treatment of pelvic floor dysfunction disease (PFD) in women with water birth. Methods A total of 110 women delivered from June 2018 to June 2019 were selected and divided into the traditional delivery group and the water birth group(n=55, each).After the pelvic floor rehabilitation training was performed in two groups, the pelvic floor muscle strength, pelvic floor distress inventory (PFDI-20), pelvic organ prolapse quantification (POP-Q) score, pelvic floor static tension and vaginal dynamic pressure were measured.The incidence of PFD and pelvic floor muscle strength were observed and evaluated between two groups. Results Compared with those in traditional delivery group, perineal injury, postpartum hemorrhage, duration of labor, incidences of pelvic floor muscle damage and PFD, scores of PFDI-20 and POP-Q significantly decreased in water birth group (all P<0.05).In water birth group, pelvic floor type Ⅰ and Ⅱ muscle fiber voltage, pelvic floor static tension and vaginal dynamic pressure were significantly higher than those in traditional delivery group(P<0.05). Conclusion In puerpera with water birth, pelvic floor rehabilitation training has a remarkable preventive and therapeutic effect on postpartum pelvic floor dysfunction disease and reduce the incidence of pelvic organ prolapse, stress fecal incontinence and stress urinary incontinence.
