RESUMEN
OBJECTIVE: To determine the effects of exercise in anatomic abnormalities of the pelvic floor (SP) and the quality of life (QOL) of women with stress urinary incontinence (SUI). METHOD: An experimental study with 50 women with SUI, distributed randomly into two groups, experimental (GE, 49.24±7.37 years) and control group (CG; 45.25±5.60 years). The groups performed ultrasound evaluation of the SP, evidence of pelvic floor muscle strength by palpation bidigital, surface EMG motor activity and replied to the CV before and after treatment. The GE had 16 sessions of pelvic floor exercises twice a week for 30min. RESULTS: Comparison between the GE and GC revealed significant differences in favor of GE, namely: mobility of the bladder neck (Δ=-0.79mm, p=0.00), thickness of pelvic floor muscle (Δ=-0.04mm, p=0.00), EMG (Δ=0.05.V, p=0.00), muscle strength by the AFA (Δ=0.05 level, p=0.00), DOMI1 (Δ%=5.67%, p=0.00), DOMI2 (Δ%=18.00%, p=0.00), DOMI3 (Δ%=18.22%, p=0.00), DOMI4 (Δ%=4.45%, p=0.00), DOMI5 (Δ%=0.22%, p=0.00), DOMI6 (Δ%=2.00%, p=0.00), DOMI7 (Δ%=3.78%, p=0, 00), DOMI8 (Δ%=6.33%, p=0.00), DOMI9 (Δ%=4.03%, p=0.00). CONCLUSION: It was modified and improved anatomic features of the pelvic floor of women from GE through perineal exercises, which will positively influence the CV of these women.
