To compare the effects of manual visceral therapy (MVT) associated with pelvic floor muscle training (PFMT) on urinary incontinence (UI) symptoms, vaginal resting pressure, and maximum voluntary contraction of the pelvic floor muscles (PFM).
A double-blinded randomized controlled trial of 5 weeks duration with two active intervention arms: PFMT + MVT and PFMT + manual sham therapy (MST). Participants were women over 18 years of age with complaint or diagnosis of UI symptoms. The primary outcome was the severity of UI symptoms, assessed by the International Consultation on Incontinence Questionnaire - Short Form. The secondary outcomes measures included the vaginal resting pressure and the maximum voluntary contraction of PFM assessed by digital manometry.
Fifty-two incontinent women participated in the study. There was no significant difference between groups in UI symptoms (F (1.74, 86.9) = 0.406; p = 0.638), vaginal resting pressure (mean difference -1.5 cmH₂0 [95% confidence interval [CI] -4.5 to 1.5; p = 0.33]), and maximum voluntary contraction of PFM (median 0.0 cmH₂0 [25%-75% interquartile range 0.0-5.6; p = 0.12]) after the intervention period.
Combining MVT with PFMT was not more effective than PFMT alone in reducing UI symptoms, in change vaginal resting pressure and maximum voluntary contraction of PFM. Due to the limitations of the study, further investigations are still needed to confirm these findings.
