Russian Stim

The RX-4000 has built in Russian Stim Technology: Russian Stimulation is a specific form of electro-stimulation with a Symmetrical Biphasic Square waveform produced by dividing a 2500 Hz carrier frequency into 50 Hz packets . While originally developed by the Russian Olympic team for muscle mass enhancement, Russian Stim is now used for muscle strengthening, muscle spasms & Edema reduction in the United States. Russian Muscle stimulation is similar to EMS. It is designed to stimulate motor nerves. However, the high frequency of 2500 Hz allows for deeper muscle penetration and a more complete/stronger contraction of the muscle fibers.
