LLLT, also called cold laser therapy or photobiomodulation therapy, is a type of phototherapy designed to repair tissue, reduce pain and inflammation, target fat and provide other benefits for patients in both medical and veterinary treatments. The capabilities of low-level lasers have been used in fat loss and pain relief for over 50 years.
Low level laser therapy (LLLT) is used by some physiotherapists to treat LBP. LLLT is a non-invasive light source treatment that generates a single wavelength of light. It emits no heat, sound, or vibration. It is also called photobiology or biostimulation. LLLT is believed to affect the function of connective tissue cells (fibroblasts), accelerate connective tissue repair and act as an anti-inflammatory agent. Lasers with different wavelengths, varying from 632 to 904 nm, are used in the treatment of musculoskeletal disorders.
During a treatment regimen, a small low-level laser therapy device emitting laser beam or visible nonthermal lasers is placed over the target area. The low levels of light penetrate the tissue without heating or damaging the skin.
