Effects of Photobiomodulation on Pain and Sexual Function in Women With Dyspareunia: Randomized Clinical Trial

The volunteers in the GFBM group will undergo 8 sessions of a combined red and infrared laser protocol with 4J of infrared power and 4J of red power. Being applied at 8 points (4 red and 4 infrared) in the vulvar region and 8 points (4 red and 4 infrared) points in the intravaginal pelvic floor region. The MMO semiconductor laser device (GaA1As and InGaAlP) will be used with an area of the output laser beam at the NOZZLE of the laser pen of 3mm2 and wavelengths of 660nm (Red Laser) and 808nm (Infrared Laser) with a power of 100mW. The application will be carried out with the volunteers on a stretcher, in the supine position, gynecological position, with the knees and hips flexed and in abduction, feet supported on the stretcher.

The placebo control will be administered using the same device as the GFBM, but without any therapeutic dose delivery. Furthermore, the irradiated sites and irradiation time will be the same as PBMT. Volunteers will receive a total dose of 0 J in placebo mode. This treatment was also carried out in 8 sessions.
