This assessor-blinded randomized controlled trial aims to compare the effectiveness of three exercise programs for the treatment of stress urinary incontinence (SUI) in women: (1) Pilates without voluntary pelvic floor muscle contraction, (2) Pilates combined with voluntary pelvic floor muscle contraction, and (3) isolated pelvic floor muscle training (PFMT). Seventy-eight women aged over 18 years with self-reported SUI are randomly allocated into three parallel groups. Interventions last 6 weeks, with two sessions per week (12 sessions). The primary outcome is the change in the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF) score from baseline to post-intervention. Secondary outcomes include urinary frequency and leakage episodes (72-hour bladder diary), pelvic floor muscle strength (Modified Oxford Scale), endurance, rapid contractions, and vaginal squeeze pressure measured by perineal manometry (Peritron). The hypothesis is that Pilates combined with voluntary pelvic floor muscle contraction will be superior to Pilates alone and comparable or superior to isolated PFMT.
