The action of low-intensity infrared laser radiation on skin afferents

Laser radiation modulates functional characteristics of mechanoreceptors. This inhibits impulse activity of the nerve endings from pain focus and reduces pain sensitivity of skin afferents, excitability of conductive nerve fibers. Changes in sensitivity become more pronounced with increasing duration of the exposure. By means of reflectory mechanism laser radiation may cause other general reactions of the body and enhance immune response of the skin.
