What is laser therapy? Laser therapy is the use of monochromatic light emission from a low intensity laser diode (250 mill watts or less) or an array of high intensity Super Luminous Diodes (providing total optical power in the 1000-2000 milliwatt range) to treat musculoskeletal injuries, chronic and degenerative conditions and to heal wounds. The light source is placed in contact with the skin allowing the photon energy to penetrate tissue, where it interacts with various intracellular bio molecules resulting in the restoration of normal cell function and enhancement of the body's healing processes. The specific effects and conditions treated by Low Intensity Laser Therapy are presented below.
