Differences in motor learning of pelvic floor muscle contraction between women with and without stress urinary incontinence: Evaluation by transabdominal ultrasonography.
To evaluate differences in motor learning of pelvic floor muscle (PFM) contraction between women with and without stress urinary incontinence (SUI) under transabdominal ultrasonography (TAUS)-guided PFM training.



Postpartum women received an intensive 3-month PFM training program from 3 to 6 months postpartum. The program consisted of home exercises and weekly group sessions with individual TAUS-guided training. Motor learning progress of PFM contraction was evaluated with TAUS at each weekly session. We regarded a woman who contracted her PFM correctly more than 9 times out of the 10 repetitions as having achieved the associative stage of motor learning. Women were evaluated before and after a 12-week intervention for PFM and SUI by using transperineal ultrasonography and questionnaire, respectively.



Seventy-three women were included: 44 primiparous women (60.3%) and 64 vaginal deliveries (87.7%). Of 73 women, 22 (30.1%) were classified as the SUI group. By the fifth session, the proportion of women who could correctly contract their PFM > 9 out of the 10 repetitions had increased significantly more in the non-SUI group than in the SUI group (90.0% vs. 58.8%, P = 0.011). The proportion of women achieving the associative stage of correct PFM contraction was not different between the two groups after the sixth session. PF morphology and SUI were improved after intervention (P < 0.05).



The proportion of women achieving the associative stage in women with SUI was less than that in women without SUI in the early phase of the combination of group and home PFM training with TAUS-guided training. Neurourol. Urodynam. 36:98-103, 2017. © 2015 Wiley Periodicals, Inc.
