All About The Working Of Cold Laser Therapy

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.  

Cold laser light treatment involves the use of handheld devices which are known as cold lasers. 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 layers of the skin. This light has the ability to penetrate 2 to 5 centimeters below the skin at 90mw and 830 nm.

Once the light energy passes through the layers of skin and reaches the target area, it is absorbed and interacts with the light-sensitive elements in the cell.

When cells absorb this light energy, it initiates a series of events in the cell that is theorized to eventually result in normalizing damaged or injured tissue, a reduction in pain, inflammation, edema, and an overall reduction in healing time by increasing intracellular metabolism.
