RESUMO
OBJECTIVES: 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). STUDY DESIGN: 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%. RESULTS: 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). CONCLUSIONS: 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.
