Stimtac 4

Interferential Electrical Stimulation is a unique way of effectively delivering therapeutic frequencies to the tissue. Interferential stimulators use a fixed carrier frequency of 4,000 Hz per second and also a second adjustable frequency
of 4,001-4,150 Hz per second. This causes the stimulation to concentrate deep in the tissues as well as at the surface of the skin. It provides more analgesic or nerve blocking effect. EMS sends electrical current through self-adhesive electrodes placed over the muscle. The current passes through the skin to the nerves in that area, causing the muscle to expand and contract, effectively exercising the muscle. EMS is predominately used by doctors and physical therapists to prevent or reduce muscle atrophy.
