Nordenstrom proved that disease and injury cause charge to be formed in affected deep soft tissue. And for healing to occur, the charge must be eliminated, either by the body itself, or with external electrical current. If the charge of injury is not dissipated, scar tissue forms, leading to restricted range of motion which can become permanent.

Nordenstrom showed that chronic pain is often sourced in old injuries to deep soft tissue, where the charge is stored rather than released. The ARP penetrates low-voltage current deep enough into soft tissue to dissipate charge of injury without surface pain.

Dr. Yakov Kots, considered by many to be the innovator of electrical stimulation used in athletics, believed that you have to have high voltage with lots of power to get deep enough penetration to affect soft tissue damage or muscle conditioning.

Russian Stim equipment, especially Stimul One invented by Dr. Kots, are very high-voltage machines which can elicit rapid results. However, the high voltage often burns the skin, and the use of weights to secure electrodes is very uncomfortable.

Nevertheless, Dr. Kots proved to the world that deep penetration of electrical current, in fact, increases the physical size of muscle fiber in as little as 10 days.

In December 1977, Dr. Kots, under an exchange arrangement worked out between Canada's Montreal Concordia College and Moscow's Central Sports Institute, proved beyond a doubt that electrically stimulating muscle, in fact, increases strength and size of muscle fiber.

Dr. Robert Becker, in his book, "The Body Electric," determined that collagen becomes electrically charged and forms scar tissue when physically abused.

Nobel Laureates, E. Neur and B. Sakmann, demonstrated that cells communicate with each other electrically. Cells embedded in charged collagen at injured sites have their communication disrupted, preventing the reduction of inflammation and edema.
