The primary uses for laser therapy currently are for pain management protocols, and stimulating improved wound and tissue healing. For instance we use it on most of our surgical incisions to speed healing and reduce post op pain and swelling. It is used a lot for musculoskeletal pain such as chronic arthritis, acute and chronic back and neck pain patients, and used a lot to enhance wound healing in large or slow healing wounds.
The mode of action for the benefits of laser therapy are still being elucidated, and basically infrared wavelength energy is used over tissues and joints in need of healing or pain reduction. Evidence shows that laser therapy stimulates the healing cells of the body through increased metabolism from the light energy, increases blood flow to tissues in need of healing, and has anti inflammatory actions. Laser energy also has anti microbial action as well.
