Laser application protocol
BLIND
The application of the low-power laser was performed with a Therapy XT (São Carlos/SP, Brazil) device which features both infrared (wavelength of 808nm +/- 10nm) and red (wavelength 660nm +/- 10nm) capacity. Infrared at a wavelength of 808nm +/- 10nm, fiber diameter 600μm, irradiation dose (energy density) of 3J/cmEach patient received two applications of LPL therapy, the first application in the immediate postoperative period, and the second application in the 48-hour postoperative period. In the placebo group, the same periods and times as the test group were respected so that the patient remained blind to the therapy, with the device being taken to the same anatomical regions with a simulated activation sound (made by sound recorded on a cell phone), yet without LPL activation.
