Photobiomodulation, also known as low-level laser therapy, is a non-invasive form of light therapy that uses low-level lasers or light-emitting diodes to stimulate cellular processes in the body. This type of therapy has been shown to have a variety of therapeutic effects, including reducing inflammation, promoting tissue repair, and relieving pain. Photobiomodulation is used in the treatment of a wide range of conditions, including musculoskeletal injuries, neurological disorders, and wound healing. Research in this area continues to explore the mechanisms of action and potential applications of photobiomodulation therapy.
