Introduction: Among the types of urinary incontinence (UI), stress urinary incontinence (SUI) is the most prevalent and, may be associated with anterior vaginal wall pelvic organ prolapse (POP). Pelvic floor muscle training (PFMT) has been the first-line recommendation to strengthen and increase the endurance of the pelvic floor muscles (PFM) in women with stress urinary incontinence (SUI) and pelvic organ prolapse (POP) in general. Objective: To evaluate the effectiveness of PFMT on quality of life (QoL) and functionality in women with SUI and POP. Methods: A randomized controlled clinical trial. The sample consisted of 32 women diagnosed with SUI and anterior vaginal wall POP. Participants were assessed at three time points: baseline, immediately post-intervention, and one month after the final assessment, following the same protocol: assessment form, functional assessment of the pelvic floor muscles (using the Modified Oxford Scale and vaginal manometry), and administration of the following questionnaires: International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF), International Consultation on Incontinence Questionnaire - Overactive Bladder (ICIQ-OAB), Pelvic Floor Distress Inventory (PFDI-20), World Health Organization Quality of Life (WHOQOL), Female Sexual Function Index (FSFI), and Patient Global Impression of Improvement (PGI-I). Participants were allocated into two groups: the PFMT group (GPFMT), which received supervised in-person PFMT (16 sessions, twice a week), and the control group (CG), which received informational material and guidance on UI and exercises to be performed at home. Results: Findings showed improvements in PFM function in both groups, with a 39.2% improvement in the GPFMT group and 13.6% in the CG. Participants in the GPFMT group also demonstrated positive impacts on quality of life, particularly in the physical, emotional, and social domains. Conclusion: The findings of this study suggest that supervised PFMT contributes more significantly to improvements in muscle functionality, reduction of urinary symptoms, and pelvic discomfort when compared to unsupervised home-based exercises. These results highlight the importance of physiotherapy as an effective conservative approach for women with stress urinary incontinence and anterior vaginal wall prolapse.
