Cold Laser Therapy or Low Level Laser Therapy (LLLT) is a treatment that utilizes specific wavelengths of light to interact with tissue and is thought to help accelerate the healing process. It can be used on patients who suffer from a variety of acute and chronic conditions in order to help eliminate pain, swelling, reduce spasms and increase functionality.
How Cold Lasers Work
Cold lasers are handheld devices used by the clinician and are often the size of a flashlight. The laser is placed directly over the injured area for 30 seconds to several minutes, depending on the size of the area being treated and the dose provided by the cold laser unit.
During this time, the non-thermal photons of light that are emitted from the laser pass through the skins layers (the dermis, epidermis, and the subcutaneous tissue or tissue fat under the skin). This light has the ability to penetrate 2 to 5 centimeters below the skin at 90mw and 830 nm.
