Laser therapy is the use of monochromatic light emission from a low-intensity laser diode to treat musculoskeletal injuries, chronic and degenerative conditions. The light source is placed in contact with the skin allowing the photon energy to penetrate tissue, where it interacts with Various intracellular biomolecules resulting in the restoration of normal cell function and enhancement of the body’s healing processes.
