When learning about laser technology, there are some basic concepts that should be understood. A laser is basically a focused beam of light that emits photon energy. When the light is focused properly, all of the photons are traveling in the same direction and at the same wavelength; this is also known as coherent light. When light is not focused, it scatters in all directions and becomes diffused. This is called non-coherent light.
BEAMS OF LIGHT
We use lasers to listen to our favorite music CD’s, to measure distance, temperature, and speed. Even though Einstein was the first to talk about the idea of beams of light, our bodies have been using the same kind of energy to communicate since man was created. As documented in James L. Oschaman’s book “Energy Medicine: The Scientific Basis”, cells communicate to one another through coherent light.
LOW LEVEL LASERS
Low-level lasers are different than more publicized heat lasers that are used in many surgical procedures to cut, and cauterize tissue. Low level lasers do not have a thermal effect and are used to situate, rather than destroy tissue. These types of lasers have been in use for over 25 years and there has yet to be one recorded side effect. Low-level laser studies have been done and have proven to be effective in many cases, but it was the ERCHONIA laser that made history by becoming the first low-level laser in the world to gain FDA market clearance for the treatment of chronic neck and shoulder pain. This was proven through two double-blind studies to prove the efficacy of the ERCHONIA laser on chronic pain.
HOW DOES IT WORK?
ERCHONIA Lasers emit visible coherent light that is applied to the affected area. Bundles of light energy pass through the dermal layers, and are received within the cell membrane by specific energy photo acceptors. The increase in intra-cellular energy results in altered cell membrane permeability, and physiological changes occur through an enzyme cascade to affect several biological processes. Within the injured musculoskeletal tissue, low-level laser light initiates increase microcirculation and enhanced tissue regeneration. The overall effects are decreased pain and inflammation, and increased range of motion.
