Is pelvic floor muscle training effective when taught in a general fitness class in pregnancy? A randomised controlled trial

Objectives

Pelvic floor muscle training (PFMT) following vaginal assessment of correct contraction can prevent and treat urinary incontinence in the peripartum period. The aim of this study was to evaluate the effectiveness of PFMT instructed in a general fitness class for pregnant women.

Design

Single-blind randomised controlled trial.

Setting

University-conducted primary care study.

Participants

One hundred and five sedentary primiparous women randomised to a general fitness class including PFMT (n=52) or a control group (n=53). Ten and 11 women were lost to follow-up in the exercise and control groups, respectively.

Intervention

Twelve weeks of training comprising twice-weekly 1-hour fitness classes including three sets of eight to 12 maximal pelvic floor muscle contractions. The control group received usual care.

Outcome measure

Number of women reporting urinary, flatus or anal incontinence.

Results

No significant differences were found in the number of women reporting urinary, flatus or anal incontinence between the exercise group and the control group during pregnancy or at 6 weeks post partum.

Conclusions

No effect of PFMT was found when the exercises were taught in a general fitness class for pregnant women without individual instruction of correct PFM contraction. Low adherence and the small sample size may have contributed to the negative results. Further studies are warranted to assess the effect of population-based PFMT in the prevention of urinary and fecal incontinence.
