Light Emitting Diode in the Treatment of Genitourinary Syndrome of Menopause

Light Emitting Diode in the Treatment of Genitourinary Syndrome of Menopause: Randomized Controlled Clinical Trial

Introduction: The genitourinary menopause syndrome (MMS) affects 50% of postmenopausal women and, due to a decrease in hormone levels, triggers functional changes in the vagina and vagina, and impairment of quality of life and sexual function. Objective: To test the hypothesis that the 405 nm light emitting diode in the treatment of vulvovaginal atrophy is safe and effective, by reducing the symptomatology of the disease and histological alteration of the tissue. Methods: This is a pilot study in 10 volunteers with SGM, followed by a randomized, blinded trial in a sample of 58 individuals that will be performed at the Pelvic Floor Care Center (CAAP). Menopausal women up to 65 years of age and with clinical signs and symptoms of vulvovaginal atrophy syndrome (vaginal dryness and irritation, pruritus, pain or discomfort in intercourse, bleeding after sexual intercourse) and who voluntarily participate in the study will be included. Will be excluded from the study the patients in hormonal replacement for less than 6 months, diagnosis of vaginal infection, use of pacemaker, pregnant women, those who have performed Oophorectomy or presented ovarian cancer, difficulty understanding the proposed instruments and patients with chronic neurological degenerative diseases. Three 405 nm light emitting diode (LED) sessions will be performed, with a seven days interval between them. In the clinical trial, the study group will perform kinesiotherapy and LED.

The control group will perform kinesiotherapy and the LED will be turned off. Data collection will be performed initially and after the sessions through self-administered questionnaires containing socio-demographic and clinical information, Medical Outcomes Study 36, Short-Form Health Survey (SF-36), Female Sexual Function Index (FSFI) - Female Version (QS-F), Female Genital Self-Image Scale - 7 (FGSIS-7). At the end of treatment, the visual analog scale and Likert scale will be used to measure the individual's satisfaction. Expected results: The 405nm LED in the vaginal canal is expected to be safe and effective for SGM.
