Laser therapy is a new treatment for pain, inflammation, swelling, and for repairing injured tissues. With regard to pain reduction, the therapy laser stimulates the synthesis of pain reducing biochemicals in the body, specifically endorphins and encephalin. Since the laser stimulates lymphatic drainage from a site, it also considerably reduces swelling and inflammation, which also has a pain reduction effect. Finally, the therapy laser stimulates muscle and trigger point providing musculoskeletal pain relief.
Accelerated healing is another benefit of the therapy laser, as photons of emitted light penetrate deeply into tissues to stimulate rapid cellular reproduction and growth. These photons also increase the amount of energy available to cells so that they can absorb nutrients while eliminating waste products faster. As a result of all of this, tissues such as tendons, ligaments, muscle and skin are repaired more quickly.
Another phenomenon that stimulates faster healing is the opening or dilation of small blood vessels in an area. More blood supply brings in healing cells faster, accelerating the healing process while reducing the formation of scar tissue.
