Photobiomodulation

Meaning

Photobiomodulation, often referred to clinically as low-level light therapy (LLLT) or cold laser therapy, is a non-invasive therapeutic technique that utilizes non-ionizing light sources, such as specific lasers or light-emitting diodes (LEDs), in the red or near-infrared spectrum to stimulate cellular function. This non-thermal process involves the light energy being absorbed by specific chromophores within the cell, leading to a cascade of beneficial physiological effects. It is used clinically to promote tissue repair, reduce inflammation, and alleviate various forms of chronic pain.
