dc.description.abstractThe dysfunctions of the female pelvic floor have a great influence on the quality of life of women, in all areas, social, psy- chological, and sexual. Stress urinary incontinence is the clinical condition in which the woman involuntarily loses urine to efforts, such as coughing and sneezing, causing great embarrassment and affecting her quality of life. The physiotherapeu- tic treatments include muscle strengthening; however, muscle fatigue is present when performing the exercises. Here we investigate the effects of photobiomodulation to prevent muscle fatigue in the pelvic floor in the treatment of stress urinary incontinence, associated with a muscle strengthening exercise protocol. We used an infrared laser (808 nm, 100 mW) and 3 J/point and fluence of 107.1 J/cm2. The application was performed at 3 points on the vaginal introits and at another 3 points inside the vaginal canal cavity for the treatment of stress urinary incontinence associated with strengthening exercises with vaginal cones. Twenty-two volunteers participated in the study, divided into two groups: group 1 (laser therapy + strength- ening) and group 2 (placebo laser + strengthening). In the group 1 quality of life score, the assessment (11.63 ± 4.33) was the highest score at 17 and in the reevaluation (7.81 ± 5.14) the lowest was 0 (p < 0.05). The muscular strength increased considerably (p < 0.05) for group 1, where the vast majority of patients gained more than twice the strength in the pelvic apparatus (8.36 ± 6.65 before X 13.81 ± 8.92 after). The volunteers acquired an increase in the contraction of the muscles of the pelvic apparatus (p < 0.05) (3.45 ± 1.07); after laser application, this number increased considerably (4.27 ± 0.61). Endurance had an increase of almost 50% compared to placebo, demonstrating the resistance gain in the perineal muscles (3.90 ± 2.35 X 5 ± 1.90). We concluded that photobiomodulation treatment showed significant efficacy in relation to muscle fatigue in the pelvic apparatus right after a strengthening program in women with stress urinary incontinence.
