Cold-laser therapy, or low-level laser therapy (LLLT), is a treatment that utilizes specific wavelengths of light to interact with tissue. This therapy can help accelerate the healing process.
When laser photons enter the tissue, they are absorbed by light-sensitive molecules in the cell, which are called chromophores. These chromophores convert energy into other forms of energy that can be used by the cell. Effects of this treatment include improved circulation through nitric oxide production and vasodilation, as well as increased ATP synthesis. These effects enhance normal cell functions.
During a cold-laser session, a physician reviews the case and diagnosis. Then, the physician selects which frequencies of laser to use and which tissues of the body to treat. A laser diode is positioned to apply energy to the affected muscles, organs or nerves. Typically, the laser is applied for 6 to 20 minutes, which varies based on the number of areas being treated.
Cold-laser therapy can be used on patients who suffer from a variety of acute and chronic conditions to help eliminate pain and swelling, reduce spasms, and increase functionality. Lasers can be used for:
