Does pelvic floor muscle training (PFMT) help prevent or treat urinary or fecal incontinence during pregnancy or after delivery?
Structured PFMT beginning early in pregnancy prevents the onset of urge incontinence later in pregnancy and in the postpartum period compared with no intervention (number needed to treat = 4; 95% CI, 3 to 9). (Strength of Recommendation [SOR]: B, based on inconsistent or limited-quality patient-oriented evidence.) There is no evidence that PFMT improves urinary incontinence later in pregnancy or in the postpartum period in pregnant patients who already have urinary incontinence. (SOR: B, based on inconsistent or limited-quality patient-oriented evidence.) There is no clear evidence that PFMT effectively prevents or treats fecal incontinence later in pregnancy or after delivery.1 (SOR: B, based on inconsistent or limited-quality patient-oriented evidence.)
More than one-third of pregnant patients experience urinary incontinence at some point in their second and third trimesters. Approximately one-fourth of pregnant patients experience fecal incontinence—the involuntary loss of flatus or feces—late in pregnancy, and about one-fifth of patients leak flatus or feces one year after delivery.1 Other factors that may increase incontinence include elevated prepregnancy body mass index, method of delivery (vaginal vs. cesarean), forceps- or vacuum-assisted delivery, multiple gestations, or history of multiple pregnancies. PFMT is the repeated voluntary contraction of the pelvic floor muscles (also known as Kegel exercises), and health care professionals commonly advise pregnant patients to do PFMT one or more times per day for at least eight weeks during and after pregnancy to prevent and treat urinary incontinence.
This Cochrane review included 46 trials involving 10,832 patients from 21 countries.1 Overall, the studies were small, and the PFMT programs varied in training methods as well as
