Impact of Pelvic Floor Muscles Training Isolated and Associated with Game Therapy on Mixed Urinary Incontinence: A Randomized Controlled Trial

Objective: To verify whether pelvic floor muscle training (PFMT) associated with game therapy (GT) can potentiate improvements in PFM pressure, urinary loss, and perception of improvement in women with mixed urinary incontinence (MUI). Materials and Methods: A randomized and blinded trial was conducted with 32 women aged between 45 to 70 years presenting diagnosis of MUI. They were randomly divided into two groups: PFMT group and PFMT+GT group. Interventions occurred twice a week during 8 weeks. Primary outcome was PFM pressure, assessed by manometry, and secondary outcomes were 1-hour pad-test, International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), and patients global impression of improvement for incontinence (PGI-I). Two-way analysis of variance and post hoc Tukey analysis were performed. Results: Initially, no significant difference between groups was found in variables of age, body mass index, educational level, marital status, gynecological and obstetric variables, life habits, and sexual activity. Besides, at baseline clinical variables also showed similar results between groups for PFM pressure, 1-hour pad-test, and ICIQ-SF. Time-group interaction did not present statistically significant differences for PFM pressure (P = 0.56), 1-hour pad-test (P = 0.75), and ICIQ-SF (P = 0.30) in intergroup analysis. All women reported being "much better or better," considering the comparison of urinary complaints in the beginning and end of treatment. Conclusion: There were no statistically significant differences between groups for PFM pressure, 1-hour pad-test, and ICIQ-SF. However, both treatments proved to be effective for MUI symptoms. Perception of improvement was highly improved, according to women's report.
