Also known as low level light therapy (LLLT), is an emerging medical and veterinary technique in which exposure to low-level laser light or light emitting diodes stimulate cellular function leading to beneficial clinical effects.

Photobiomodulation (PBM) involves the use of visible or near infrared light (NIR) produced by a laser or a non-coherent light source applied to the tissue of the body to produce beneficial effects in a wide range of disease states.

Photobiomodulation (PBM) stimulates cellular processes through photoacceptors, and has evolved as a mainstream therapeutic modality. It is widely used in physiotherapy, chiropractic and sports medicine, and increasingly, recognized as a potential therapy for the treatment of serious, life-threatening disease states.
