Microcurrent Electrical Therapy (MET) devices use sub-sensory current (millionths of an amp) that acts on the body's naturally occurring electrical impulses in an attempt to decrease pain, improve mood and facilitate the healing process.
Microcurrent Electrical Therapy (MET) current is delivered through different kinds of devices - via water or gel-moistened electrodes, felt pads, or through the finger tips of black graphite gloves. For MET treatments, electrodes are placed over the painful area on opposite sides of the body, so that the current runs through it. Microcurrent is sub-sensory and cannot be felt while it is being delivered because there is not enough current to stimulate the sensory receptors. Treatment time varies with the size of the injured or diseased site. The effect of the treatments is said to be cumulative, so at least three treatments are typically needed before pain relief sets in.
One theory on how MET may work to relieve pain and speed up healing is that it increases the production of ATP (Adenosine Triphosphate) in the cell, which helps promote protein synthesis and healing.
