    Low Level Laser Therapy

    also LLLT

    Low-level laser therapy (LLLT), cold laser therapy, or photobiomodulation (PBM) is a photochemical reaction-based medical treatment that applies low-level (low-power) lasers or light-emitting diodes (LEDs) to the surface of the body without damaging tissue. Proponents claim that this treatment stimulates healing, relieves pain, and enhances cell function. Sometimes termed as low-level red-light therapy (LLRL), its effects appear to be limited to a specific range of wavelengths. Its effectiveness is under investigation. Several such devices are cleared by the United States Food and Drug Administration (FDA). The therapy may be effective for conditions such as juvenile myopia, rheumatoid arthritis, and oral mucositis.
