Effects of two nonpharmacological treatments on the sleep quality of women with nocturia: a randomized controlled clinical trial.

Introduction and Hypothesis: The objective was to check the effects of two nonpharmacological treatments on the sleep quality of women with nocturia.
Methods: A randomized controlled clinical trial in which 40 women with nocturia were randomized into two groups; one was subjected to tibial nerve stimulation (GTNS) and the other received pelvic floor muscle training associated with behavioral therapy (GPFMT). Both groups were followed for 12 weeks, with one session/week; evaluated by the Pittsburgh Sleep Quality Index (PSQI), King's Heath Questionnaire (KHQ), and Epworth Sleepiness Scale (ESS). The Wilcoxon test was used to compare intra-group data and the Mann-Whitney test for intergroup results. Effect size and confidence interval were calculated, and the level of significance was set at 5%.
Results: Both groups showed improvements in quality of sleep, observed by the PSQI total score (GTNS from 9 ± 0.88 to 7 ± 0.94, p = 0.002; GPFMT from 8 ± 0.80 to 5 ± 0.94, p < 0.001) and the sleep/energy domain of the KHQ (GTNS from 66.66 ± 9.03 to 16.66 ± 7.20, p = 0.002; GPFMT from 66.66 ± 9.30 to 0.00 ± 7.26, p = 0.001).
Conclusions: Both nonpharmacological treatments proposed (TNS or PFMT) were equally able to improve quality of sleep of women with nocturia.
