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 skin’s 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. The laser therapy can stimulate all cell types including muscle, ligament, cartilage, nerves, etc., so a number of conditions can be treated by cold laser therapy. Some of conditions that may typically be treated by cold laser therapy include:
For years, physicians have been using cold laser therapy on patients who are seeking effective, alternative methods for pain relief. Since 1967 there have been over 2,500 clinical studies published worldwide. Many of these studies are double-blinded, placebo-controlled and have demonstrated cold laser therapy to be a proven method for pain relief.
