RESUMO
PURPOSE: To determine the efficacy of physiotherapy and behavior therapy and to find specific subgroups of women with overactive bladder syndrome that might gain increased benefit from this therapy. METHODS: Women with ≥10 micturitions per 24-h period were included. Six to nine therapy sessions were held within a 14-day interval. Efficacy end point was a reduction in micturitions and in episodes of nocturia. Secondary outcomes included ICIQ-OAB, ICIQ-OABqol and visual analog scales. Follow-up was 6 months. Levene test, Student's t test, Pearson´s and Spearman's correlations were utilized as well as the Friedman test and a multivariable-multilevel model. RESULTS: 32 women were included. Mean age was 51 ± 15.9 (years ± standard deviation, sd). Mean body mass index (BMI) was 24.4 ± 4.8 (kg/m2 ± sd). There was a 22.9% reduction in the number of micturitions per 24 h (11.7 ± 1.6 vs. 9.0 ± 1.3 p < 0.001), a 21.3% reduction during the day (10.3 ± 1.4 vs. 8.1 ± 1.1 p < 0.001) and a 34.7% reduction in episodes of nocturia (1.5 ± 1.0 vs. 1.0 ± 0.8 p = 0.026). Both ICIQ-OAB (8.7 ± 2.3 vs. 5.8 ± 2.7 vs. 6.3 ± 3.3 p < 0.001) and ICIQ-OABqol (73.4 ± 25.9 vs. 47.5 ± 14.5 vs. 47.7 ± 18.6 p < 0.001) questionnaires as well as VAS (7.5 ± 1.4 vs. 4.1 ± 2.4 vs. 4.2 ± 2.7 p < 0.001) showed significant improvement persisting in the 6-month follow-up. In addition, in a multivariable model controlling for age, women who were overactive bladder syndrome therapy naïve responded significantly better than those who had already been under therapy (p < 0.001). CONCLUSIONS: This study shows the efficacy of physiotherapy and behavior therapy in women with overactive bladder syndrome with a post-therapy effect especially for women with no prior treatment.
