Laser Therapy is the use of specific wavelengths of light (red and near-infrared) to create therapeutic effects. These effects include improved healing time, natural pain reduction, increased circulation and decreased swelling. Laser therapy works by stimulating production of cellular energy in damaged cells and by enhancing the cell membrane permeability. This promotes the speed and the quality of healing, enhances the exchange of nutrients and wastes across the cell membrane and improves elasticity of injured tissues. Laser therapy also modulates pain and reduces inflammation. Laser therapy enhances the rate and quality of healing of acute injuries, and can help with the relief of chronic complaints such as arthritis.
