The lack cellular of oxygen and poor blood supply allows the cells and tissues to take advantage of the benefits of the LEDs narrow band, near IR energy. Multiple studies have demonstrated that under these compromised conditions, the introduction of near IR energy enhances the tissue’s metabolic activity in these injury-challenged tissue components. While the near IR energy from LED pain therapy has a significant effect on damaged cells and tissues, normal healthy cells and tissues are appreciably less affected.
The cellular cascade (a series of interlocking biological events) effect led to by the actions of enzymes and the presence of near IR light has a significant impact on cell and tissue function. A considerable number of the reactive proteins, which respond to near IR energy, are enzymes. The effects of near IR energy are amplified in the stimulation of beneficial enzymes and depression of detrimental enzymes.
What are these effects? The particular affinity of photoreactive enzymes to accelerate their functions in the presence of narrow band, near IR energy provides a critical increase in the molecule ATP (cellular energy unit) and Nitric Oxide (NO, a potent vasodilator which increases local blood circulation). These increases enhance cellular metabolism and circulatory improvement as well as nerve function. In short, the near IR energy of LED pain therapy facilitates cellular and tissue repair, which in turn, relieves pain.
