Rumba Dance Combined with Breathing Training as an Exercise Intervention in the Management of Stress Urinary Incontinence in Postmenopausal Women: A Randomized Controlled Trial

Purpose: Stress urinary incontinence (SUI) refers to involuntary leakage from the urethra, synchronous with exertion/effort, sneezing or coughing, which has a negative effect on quality of life. Studies have shown that mild-to-moderate physical activities reduce the risk of SUI by multiple mechanisms. The objective of this study was to determine whether the Rumba dance combined with breathing training (RDBT) can reduce the severity of incontinence and improve the quality of life of patients with SUI. Methods: A randomized clinical trial was conducted with women who were sedentary, were postmenopausal, reported mild-to-moderate SUI on a 1-h pad test, were not already engaged in Rumba dance and did not receive estrogen replacement therapy. The patients were randomly assigned to the RDBT group (n = 13) or the control group (n = 11). The intervention included 90 min of RDBT three times per week for 16 weeks, and the vaginal resting pressure (VRP), pelvic floor muscle (PFM) strength and endurance, 1-h pad test, International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF), and the Incontinence Quality of Life Questionnaire (I-QOL) were measured or completed at baseline and 16 weeks. None of the participants reported adverse events. Results: The mean (+/- SD) age of the participants was 55.75 +/- 5.58 years. After 16 weeks, in the RDBT group, the urine leakage on the 1-h pad test was significantly decreased -2.91 +/- 0.49 from the baseline (p = 0.000). The VRP increased from 76.00 +/- 16.23 cmH(2)O to 95.09 +/- 18.90 cmH(2)O (p = 0.000), the PFM endurance of class I (-3.15 +/- 1.99% vs. -0.46 +/- 0.97%, p = 0.000) and class II (-0.69 +/- 0.95% vs. -0.23 +/- 0.44%, p = 0.065) increased, and the grades of PFM strength of class I and class II were significantly enhanced (p < 0.01). Finally, the severity of self-reported incontinence (ICIQ-UI SF) significantly decreased from 6.12 +/- 2.15 to 3.81 +/- 1.68 (p = 0.000), and quality of life (I-QOL) improved from 75.73 +/- 11.93 to 83.48 +/- 7.88 (p = 0.005). Conclusion: A 16-week RDBT program can increase PFM strength and endurance to reduce the severity of incontinence symptoms and improve the quality of life in patients with SUI, demonstrating the feasibility of recruiting and retaining postmenopausal women with SUI into a RDBT therapeutic program.
