Is a pelvic floor muscle training program, called pelvic floor workout (PEFLOW), effective in preventing postpartum stress urinary incontinence (SUI)?In this randomized clinical trial including 764 primiparous women, participants in the exercise group had a significantly lower incidence of SUI than participants in the control group at 6 weeks post partum (8.7% vs 13.9%).The finding of this study suggests that PEFLOW effectively reduced postpartum SUI incidence and may prevent SUI in pregnancy.
