Specific wavelengths of light energy, when properly absorbed, up-regulates compromised cells. The light (photons) energy is absorbed by photo acceptors in the mitochondria and used to create adenosine triphosphate (ATP). The ATP produced then stimulates various metabolic processes which can result in the

repair and regeneration of cell and tissue components.

 

In an article, "Therapeutic Light" - by Chukuku S. Enwemeka, PT, PhD, FACSM, Enwemeka writes that other reported mechanisms of light-induced beneficial effects include modulation of prostaglandin levels, alteration of somatosensory evoked potential and nerve conduction velocity, and hyperemia of treated tissues.

 

The resulting clinical benefits include pain relief in conditions such as carpal tunnel syndrome, bursitis, tendonitis, ankle sprain, and temporomandibular joint dysfunction, shoulder and neck pain, arthritis, and post-herpetic neuralgia, as well as tissue repair in cases of diabetic ulcers, venous ulcers, mouth ulcers, fractures, tendon ruptures, ligament tears, torn cartilage, and nerve injuries.
