In an article, “Therapeutic Light” - by Chukuku S. Enwemeka, PT, PhD, FACSM, he wrote “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 resultant 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 ulcer, venous ulcer, mouth ulcer, fractures, tendon rupture, ligamentous, tear, torn cartilage, and nerve injury.”
