The aim of this study was to investigate the effectiveness of pelvic floor muscle training in reversing pelvic organ prolapse and alleviating symptoms.


This assessor-blinded, parallel group, randomized, controlled trial conducted at a university hospital and a physical therapy clinic randomly assigned 109 women with prolapse stages I, II, and III to pelvic floor muscle training (n = 59) or control (n = 50). Both groups received lifestyle advices and learned "the Knack." In addition, pelvic floor muscle training comprised individual physical therapy sessions and home exercise. Student t test, Mann-Whitney U test, odds ratio, and effect size were used to compare groups.


Eleven (19%) women in the pelvic floor muscle training group improved 1 Pelvic Organ Prolapse Quantification System stage vs 4 (8%) controls (P = .035). Compared with controls, the pelvic floor muscle training group elevated the bladder (difference: 3.0 mm; 95% confidence interval, 1.5-4.4; P < .001) and rectum (5.5 mm; 95% confidence interval, 1.4-7.3; P = .022) and reduced frequency and bother of symptoms compared with controls.


Pelvic floor muscle training is without adverse effects and can be used as treatment for prolapse.
