A collaboration of physiotherapists in Brazil and Norway recently published just such a trial. Ninety-six women with an indication for POP surgery were enrolled. Half were randomised to an experimental group, which received a 9-week pelvic floor muscle training protocol with four sessions before the surgery and seven sessions after the surgery. Half were randomised to a control group that received surgery only.
There was no substantial difference in POP symptoms between the experimental and control groups at post-surgical day 40 or day 90.
On a scale from 1 (very much better) to 7 (very much worse), the experimental group perceived marginally greater global improvement than the control group; mean difference –0.4 (95% CI –0.8 to –0.1) at Day 90. However, the estimated effect of additional perioperative pelvic floor muscle training was estimated to be not beneficial enough to be considered worthwhile for any other secondary outcomes.
