Low level laser therapy (LLLT) or Photobiomodulation works by promoting and accelerating the body’s natural healing mechanisms. The light energy is converted into cellular energy, fueling the body's cells to work more effectively in the healing process. The effects of low level laser therapy are photochemical. Cells in the body have light sensitive chemicals called cytochromes. These chemicals are located in energy compartments in the cell called mitochondria. Holding the laser device directly on the skin over the injured area for a period of several minutes, a beam of light penetrates the tissue into muscles and joints. When LLLT light penetrates deep into tissue it stimulates the cytochromes in the mitochondria to produce a natural chemical compound known as ATP (adenosine triphosphate). ATP stores the energy that fuels the body’s cells and heals tissue. The increased production of ATP brings oxygen-rich blood to the injured area, reducing stress and accelerating healing. As tissue is repaired, the patient experiences pain relief and reduced inflammation.
