Cold laser therapy, also known as low-level laser therapy (LLLT) or photobiomodulation, is a type of musculoskeletal treatment that use amplified light given in a narrow beam. Cold lasers, unlike surgical lasers, do not cut or burn the skin.
The laser penetrates the underlying tissues that require attention. It causes a rise in the cellular generation of ATP, which is an energy source. This additional energy can subsequently be used by cells to repair and replenish themselves.
