Electrical muscle stimulation (EMS) is a type of electrotherapy that uses electrical impulses to stimulate muscular contractions in order to strengthen weak muscles, reduce swelling, relieve pain, and aid healing.
NMES (Neuromuscular Electrical Stimulation) employs high-intensity electrical stimulation to elicit peripheral nerve activation and muscle contraction.
A device generates the impulses, which are then supplied by electrodes (skin-attached pads) across the muscles that need to be stimulated. EMS impulses are similar to the central nervous system’s action potential, and makes the muscle contract, similar to how the nervous system would.
By using small (and painless) amounts of electrical current, specific, targeted muscles are rapidly contracted and released. This relaxes the muscles and enables the adjustment to be more effective.
