Laser therapy, it almost sounds like something out of science fiction, calling to mind brightly colored lasers that cut through anything and everything. How on earth can it work as medicinal treatment? High Power Laser Therapy (HPLT) can be applied to the surface of the body to relieve pain and even enhance cell function. It must be administered by a trained health practitioner. While not the most common treatment, it can relieve pain, soreness, and discomfort. When applied, the light emitted by the laser pass through the skin’s layers. This focused beam of light has the ability to penetrate two to five centimeters. Once it passes through the skin, it is absorbed by the cells of the targeted area, initiating a series of events that stimulates healing by increasing cellular metabolism. There have been over 2,500 clinical studies published worldwide since 1967 on the use of laser therapy.
