L.A.S.E.R. stands for Light Amplification by Stimulated Emission of Radiation. Laser Therapy involves application of low intensity laser light to relieve pain caused due to the damage of soft tissue. It facilitates tissue repair and restores normal cell function. The technique used in Physiotherapy is the "cold" Laser Therapy because the low levels of light aren't enough to hat the body's tissue. It is used be experts to heal wound and pain. The level of light is quite low as compared to other forms of Laser Therapy, such as those used to destroy tumors and coagulate tissues.
During this procedure the non-thermal photons of light that are emitted from the Laser pass through the skin layers. Once the light passes through the layers of the skin and reaches the target area.The body tissue then absorbs the light and initiates a series of events in the cell resulting in the healing of damaged or injured tissue, reduction in pain and inflammation and an overall reduction in healing time by increasing intra cellular metabolism.
