Proven, long-lasting relief from the
constant battle with pain
In order to treat the pain, you have to reach it
RS-4i® Plus Sequential Stimulator with Intersperse®
This true high frequency device for in-home use uniquely delivers both pain relieving Interferential Therapy that penetrates deep into soft tissue to excite the body’s natural endorphin production for long-lasting pain relief and the rehabilitative muscle stimulation of neuromuscular electrical stimulation (NMES) that reduces muscle spasms, increases circulation, and prevents disuse atrophy.
Exclusive to the RS-4i Plus, patented Intersperse technology provides the muscle contraction of NMES, with pain relieving Interferential pain relief inserted during the relax periods. You get intermittent contraction, then pain relief, then contraction throughout the duration of sessions, enabling shorter, more comfortable, and more impactful treatments.
“It’s my magic pill for pain relief.”
— Giles, retired Army Veteran
