laser therapy

Photobiomodulation, also known as low level laser therapy (LLLT), cold laser therapy, and laser biostimulation, is an emerging medical and veterinary technique in which exposure to low-level laser light can stimulate or inhibit cellular function leading to beneficial clinical effects. The technique is also known by the more ambiguous terms phototherapy and laser therapy, which may also be used to describe other medical techniques. The "best" combination of wavelength, intensity, duration and treatment interval is complex and sometimes controversial with different diseases, injuries and dysfunctions needing different treatment parameters and techniques. These are still being explored and increasingly published by the academic community. USA National Institute for Health database.
