Pelvic floor muscle training is recommended as first-line treatment for urinary incontinence in women.
The recommendation is strong because exercise has low costs, rarely has any harms compared to drug treatments, increases quality of life, and may be beneficial for sexual function.
A Cochrane review [Abstract] 1 included 31 studies with a total of 1 817 women. Most studies were at moderate to high risk of bias, however, the evidence is upgraded by large magnitude of effect. There was considerable variation in interventions used, study populations, and outcome measures. Women with stress urinary incontinence who were in the pelvic floor muscle training (PFMT) groups were 8 times more likely than the controls to report that they were cured) and 6 times more likely to report cure or improvement (table T1). Women with any type of urinary incontinence, who did PFMT, were 5 times more likely to report cure and 2 times more likely to report cure or improvement than controls (table T2). PFMT women also experienced fewer incontinence episodes per day, and reported better continence specific quality of life.

An RCT 2 assessed the efficacy of group-based PFMT relative to individual PFMT in older women (n=362). After an individual session conducted to learn how to contract pelvic floor muscles, participants completed 12-week PFMT as part of a group of 8 women or in individual sessions. Median percentage reduction in urinary incontinence episodes was 70% (95% CI 44% to 89%) in individual PFMT compared with 74% (95% CI 46% to 86%) in group-based PFMT.
