Class IV laser therapy Laser Therapy used for pain relief, it also increases healing and reduces inflammation. The high power diode laser targets cytochrome c oxidase and hemoglobin which improves cell respiration this provides enhanced therapy. When light source is applied to skin, photons will penetrate several centimeters into the mitochondria (the part of the cell that produces energy) where it is absorbed. Laser therapy is effective in treating multiple medical conditions these include, sports injuries, post-surgical wounds, musculoskeletal problems, arthritis, dermatological conditions and diabetic ulcers. This additional energy acts as a fuel to initiate several physiological responses which results in the restoration of normal cell morphology plus its function. The main goal of laser therapy is to stimulate the cell so as to perform its natural functions at an accelerated rate. This Class IV laser is in sharp contrast when compared to cold lasers which do not provide sensation or feeling.
