Beware Of Laser Therapy Claims

"Low-level laser therapy (LLLT) refers to the use of a red-beam or near-infrared laser with a wave-length between 600 and 1000 nanometers and power from 5 to 500 milliwatts. Depending on wavelength, tissues absorb energy to produce heat. LLLT lasers transfer small or very small amounts of energy into the skin. In contrast, lasers used in ablative surgery typically use 300 watts and burn the tissues they encounter. LLLT devices may bring about temporary relief of some types of pain, but there is no reason to believe that they will influence the course of any ailment or are more effective than standard forms of heat delivery [2]."
