RS-4i® Plus Sequential Stimulator

The RS-4i Plus combines premodulated Interferential therapy at 5000 Hz and NMES at 71 Hz in one device, uniquely providing both pain relief and muscle rehabilitation.

Intersperse®: Muscle stimulation plus long-lasting pain relief in less treatment time

The RS Medical patented Intersperse technology, offered exclusively in the RS-4i Plus, delivers Interferential Therapy for pain relief and NMES for strengthening in a single ~30 minute treatment—no need to move electrodes or switch devices. During the relax period of the muscle stimulation, pain relief signals are delivered. It’s the best of both worlds in one seamless session—work the muscle, knock down the pain, repeat.

The real-world results – less pain, fewer medications, more and better living

RS Medical has developed a baseline patient assessment adapted from the Defense and Veterans Pain Rating Scale (DVPRS) that evaluates a patient’s pain, spasms related to activity, as well as sleep, mood, and stress prior to use of the RS-4i Plus.
