Evaluation of satisfaction of pelvic floor muscle training isolated and associated with tibial nerve stimulation in women with mixed urinary incontinence: A randomized, single-blinded clinical trial.

To compare the satisfaction degree and pelvic floor manometry after pelvic floor muscle training isolated and associated with tibial nerve stimulation in women with mixed urinary incontinence (MUI).

A randomized, single-blinded clinical trial was conducted. 24 women diagnosed with MUI were equally divided into two groups: pelvic floor muscle training isolated and associated to transcutaneous tibial nerve stimulation (TTNS). The study occurred in four stages: 1) evaluation: general information, pelvic floor manometry, the International Consultation on Incontinence Questionnaire - Urinary Incontinence - Short Form (ICIQ-UI-SF) and International Consultation on Incontinence Questionnaire - Overactive Bladder (OAB) application; 2) intervention: carried out over 2 months twice a week; 3) post-intervention evaluation: vaginal manometry, reapplication of the questionnaires and the Patient Global Impression (PGI) application at the end of the 2-month intervention; and, 4) follow-up: evaluation after 1 month of the end of the intervention. The primary outcome was the ICIQ-UI-SF and the secondary outcomes were ICIQ-OAB, vaginal manometry, and PGI. The repeated measures ANOVA was used to assess the time-to-group interaction by assigning a significance level of 5%.

There was no interaction between time and group for ICIQ-UI-SF (p = 0.17) and manometry (p = 0.56). There was interaction for ICIQ-OAB (p < 0.01). PGI was reported as "much better" with 41.67% in the PFMTG + TTNS and 16.67% in the PFMTG after the intervention (p = 0.04).

The results showed weak evidence that TTNS, in combination with PFMT, may be an intervention that can be used to treat MUI. The satisfaction degree was better with associated intervention.
