The pain relief provided by high-frequency Interferential therapy can have life-enhancing effects for your chronic musculoskeletal pain patients. Why is high frequency better at treating pain? It goes deeper.

The nature of high frequency assures that these electrotherapy signals are able to overcome the skin’s natural resistance and reach nerves deep in the tissue, providing fast-acting pain relief via Gate Control. As an added advantage, they also offer long-lasting pain relief via the release of endogenous opiates.

But high-frequency stimulation isn’t the only technology that makes the RS-4i Plus different. It’s just the beginning.

  • Pre-modulation - The RS-4i Plus uses a pre-modulated signal that treats a larger area of tissue than a standard TENS.

  • Intersperse® - The RS-4i Plus is the only device that combines Interferential therapy for pain relief and NMES for muscle rehabilitation in a single treatment session.

  • Pulse width control - The unique NMES waveform is engineered to stimulate both faster- and the hard-to-reach slower-twitch muscles to improve muscle function.
