Can you explain the purpose of N.E.S.?

N.E.S. is an electrical current that passes through the joints and soft tissues such as muscles, ligaments, tendons, and capsules. The current decreases swelling and improves circulation. Decrease in inflammation is critical for pain control and for limiting cell death. N.E.S. promotes rejuvenation of cells.

The electrical stimulation relaxes hypertonic and spasmodic muscles. This also helps the healing process by enabling  more blood and lymphatic supply into the injured area.
