- What is it?
Since the late 1970's, a new breed of therapy devices have received attention from Veterinarians, Equine Therapists Trainers and horse enthusiasts.
Photon energy delivery devices are often called lasers, although many are not laser in the strict definition of the term. Words become embedded like fossils in our everyday language, and although a word can be used incorrectly, it is used continuously, out of habit. Although "laser" is the "popular" term, it is not accurate for the light therapy used today. "LASER" (Light Amplification by Stimulated Emission of Radiation) is applied generally to many light-emitting devices used in medicine, industry and everyday life. It indicates that the emitted light's power is greatly increased, or amplified, by emissions from substances contained in the apparatus.
Lasers are devices that amplify light and produce coherent light beams, ranging from infrared to ultraviolet. A light beam is coherent when its waves, or photons, propagate in step with one another. Laser light, therefore, can be made extremely intense, highly directional, and very pure in color (frequency). That is why true laser light can "cut" and is used in many surgical applications.
It is not the device, but the photo-energy produced that creates the biological effect. Photo-therapy or Photon Therapy are more accurate terms, as it is the interaction between the light photons and biological molecules that causes the effect.
Photo-energy has been shown to aid the natural recuperative capabilities of an animal and to more effectively promote healing, however, recent research has established that these biological effects are not the result of the special properties of laser light but can be achieved with the proper wavelength and energy density of non coherent monochromatic light from superluminous diodes. 1, 2, 3, 4, 7, 47
Therapeutic treatments with photo-energy can be provided on a regular basis to enhance the healing process and has also been used as a therapeutic tool for the prevention on injuries.
