Patients Go from “Hopeless” to “Heaven” with the RS-4i® Plus
Those who suffer from chronic pain, Veterans and civilians alike, often say there is no “magic pill” for relief and they simply become accustomed to living with their condition.
Most have tried a range of treatments – from physical therapy and massage to injections and even surgical procedures – some with good success. Some with limited improvement or no improvement at all.
Others, though, have found that there is another option. A prescription-grade therapy that’s non-invasive and drug free, and provides real pain relief for 84% who use it – the RS-4i® Plus with Intersperse. In fact, a number of the patients who have discovered this treatment call it a “life saver.”
If you’re a patient who hasn’t yet discovered the RS-4i Plus, read on to see if this device might be the therapy that can be a “miracle” for your chronic pain.
Twice the Therapy: Advanced Pain Relief, Plus Muscle Rehabilitation
Unlike other pain management devices that only offer a single type of therapy, the RS-4i Plus features a powerful combination of high-frequency Interferential therapy (IFT) and neuromuscular electrical stimulation (NMES).
Why are two therapies better? Because IFT and NMES act on different nerve groups. Interferential treatment targets the nerves responsible for sending pain signals, while NMES targets motor nerves in the muscle tissue. With both, the RS-4i Plus delivers the dynamic duo of pain relief and muscle rehabilitation that less sophisticated devices can’t provide.
And there is one additional, unique advantage – the RS-4i Plus combines both of these potent therapies into one session. This patented technology is called Intersperse.
During an Intersperse session, pain relief treatment is inserted between muscle stimulation treatment. Combining two treatments in one session results in shorter treatments that patients find more comfortable and more impactful. In fact, a single 35-minute session can provide pain relief lasting up to 8 hours.
A Documented Record of Patient Success
Because the device is compact and designed for home use, it’s easy to fit treatments into your daily schedule. There’s no travel time and no scheduling. Just apply the electrode pads and start getting relief.
Results show 84% of RS-4i Plus patients report a medically meaningful reduction in pain after just one month of use*. Here are the words that patients use to describe their results after using the RS-4i Plus:
“It’s taken my pain levels to 0 and increased my mobility in tenfold.”
“I am 90% pain free most of the time. I’m no longer afraid to try out more physical activities.”
“This device works 10 times better than a TENS.”
“Prior to the RS-4i Plus, my pain level was around 8. Now it’s a 2.”
“It’s been a miracle with my pain. I’ve tried everything, and nothing comes close.”
“A couple months ago I was in a wheelchair. Since the RS-4i plus, I’m walking again.”
“It’s reduced muscle spasms that left me unable to do anything by 75%.”
*2025 RS Medical data – patient-reported response to RS-4i Plus treatment on assessments; analysis of greater than 30,000 patient assessments from U.S. Veterans treated with the RS-4i Plus and followed for one month.
A Closer Look at the RS-4i Plus
The RS-4i Plus is an advanced home-use electrotherapy device that combines high frequency (5000 Hz) Interferential Therapy (IFT) for long-lasting pain relief, with Neuromuscular Electrical Stimulation (NMES) for muscle rehabilitation. Patented Intersperse technology delivers both IFT and NMES during the same, uninterrupted treatment session. This excites the body’s natural beta-endorphin production to relieve pain for up to 8 hours, and provides rehabilitative muscle therapy that reduces muscle spasms, increases circulation and prevents disuse atrophy.
