The subjects were 49 postpartum women with a normal vaginal delivery, 25 in the experimental group and 24 in the control group. Data was collected from June 1. 2007 to April 30. 2008 at a postpartum women's care center located in Jeonju, Korea. For the experimental treatment, an incontinence prevention program was carried out for 24 weeks. Measures included maximum pressure of pelvic floor muscle contraction and duration of pelvic floor muscle contraction at pre-treatment, 5 weeks postpartum and 24 weeks postpartum. Data was analyzed by Repeated ANOVA using the SPSS/WIN 14.0 program. RESULTS: The mean maximum pressure of pelvic floor muscle contraction (F = 8.95, p<.001) andmeandurationof pelvicfloormusclecontraction(F = 22.01, p<.001) were significantly different between the groups, and significantly increased as time passed. CONCLUSION: Practiceof anincontinencepreventionprogramisconsideredan effective intervention for the results of fewer urinary incontinence symptoms in postpartum women.
