Light is a form of electromagnetic energy that can be absorbed by cells and used as energy for cellular function. Light-emitting therapeutic devices generally are called lasers, although many are not lasers in the strict defintion of the term. To avoid confusion, we use the term "photon therapy" to describe the benefits that both laser and non-laser devices provide.
Whether produced by a true laser or a photon device, a beam of light energy travels thorough space or tissue and can be reflected, scattered, refracted (bent) or absorbed by molecules it encounters. Unlike ultrasound therapy, which heats specific tissues, photon therapy stimulates the release of neurotransmitters which activate cell functions without raising tissue temperature.
Photon therapy can be used for both acute and chronic injuries and for a variety of problems, including:
blood circulatory and lymph system stagnation
surface and deep wounds
