Cold Laser Therapy or Low-Level Laser Therapy (LLLT) is a specific treatment that utilizes wavelengths of light that work with body tissue to help accelerate the healing process. It can be used on patients who suffer from a variety of conditions in order to help eliminate pain, swelling and increase functionality.
Cold lasers are typically handheld devices often times the size of a small flashlight. The laser is placed directly over the injured area for 30 seconds or up to several minutes, depending on the size of the area being treated and the dose provided by the cold laser unit.
During treatment, the non-thermal photons of light that are emitted from the laser pass through the skin layers.
