Laser and LED beams of light can stimulate the cells in the body that repair tissue, reduce inflammation and transmit pain.
Light can stimulate or inhibit cellular function according to it's intensity and the time applied.
Lasers and LED's produce intense beams of light at specific wavelengths. When the right wavelength at the right intensity is used at the correct anatomical location for the right amount of time you can stimulate repair, resolve inflammation and reduce pain.
One of the primary mechanisms is the effect of light on cytochrome c oxidase and the consequently the unbinding of nitric oxide and release of ATP leading to improved cellular function. For anti-inflammatory effects we have found a measurable reduction in PGE2, TNF Alpha and IL-6 in the synovia surrounding damaged tendons and for analgesia high intensity lasers over nerve supply can inhibit fast axonal flow.
In addition, high intensity single point lasers can release trigger points and treat acupuncture points instead of needles.
