After a traumatic car accident and over 20 surgeries, Martin faced years of recovery—physically, emotionally, and mentally. But with persistence and the right tools, he found relief that helped him reclaim his life. One device became essential in helping him manage daily pain and show up for the moments that matter most: the RS-4i® Plus with Intersperse.

A Life-Changing Collision

“The morning of my accident, I was coming back from Los Alamitos, going back to Seal Beach Weapons Station. A car in the carpool lane—a blue Honda Accord—just dead stopped in front of me. I had nowhere to go. No time to respond. It happened so fast.”

Martin’s life changed in an instant. What followed was a long hospitalization, extensive surgeries, and years of rehabilitation.

“I spent three months at UCI, and I've subsequently had 23 surgeries. Pelvic reconstruction. I’ve got 32 pins, two metal plates to completely rebuild my pelvis. It took me two and a half years to learn how to walk again.”

The physical injuries were only part of Martin’s journey. The emotional weight of trauma and pain took its own toll.

“You go through the full litmus, the full gamut of emotion. First, you're angry. Then you start thinking, why me? I didn't do anything wrong. Why did this happen to me? Then you go to the depressive stage. Then you think about suicide. I've gone through it all.”

Finding a New Way to Manage Pain

Martin had tried TENS units before, but the relief they offered was minimal. That changed when his physician at the VA recommended the RS-4i Plus, a non-invasive, prescription-only electrotherapy device.

“I first learned about the RS-4i Plus from my doctor…I was like, ‘I've used TENS units before. I crank those things up, and they've never done anything for me.’ But this one…It felt like it went in, and it felt like it was doing something.”

Unlike traditional TENS units, the RS-4i Plus combines Interferential current (INF) and Neuromuscular Electrical Stimulation (NMES)—a dual approach that not only helps manage pain but also reduces muscle spasm and atrophy. Specifically, the patented Intersperse technology alternates these signals within a single treatment, resulting in sessions that deliver deeper and more effective relief in a shorter period of time.

“I'm not here to lie and say—oh my god—this was miraculous, my pain was gone. No. But I will say if my pain was a 10, it probably would have controlled the pain to a six. And anyone that suffers from chronic pain knows that’s a great number to feel—a six and below.”

A Vital Part of Martin’s Daily Routine

For Martin, the RS-4i Plus became more than just a tool—it became part of his daily rhythm.

“I use it in the morning when I wake up, before I do my stretches. I use it at night before I go to sleep, and there’ll be times where I’ll use it during the day over the course of the day.”

With regular use, he was able to manage his pain more proactively—and sometimes, it meant the difference between missing out and being present.

Showing Up for Life’s Most Important Moments

“I was able to attend my son's wedding. And the night before I had been just hit with a bad nerve pain, and I was hurting. I remember telling my wife, ‘I don't know if I'm going to be able to make it, and if I do, it's going to be a horrible day for me.’”

Determined not to miss the milestone, Martin turned to his RS-4i Plus.

“I used the RS-4i prior to going to bed that night, and I felt a little bit of a relief. I woke up in the morning, my nerve pain was manageable…I put the RS-4i back on, and by the time we had gotten to the wedding, I felt my pain was at a level that I could function. That's just a day I didn't want to miss.”

About the RS-4i Plus

The RS-4i Plus is an advanced home-use electrotherapy device that combines true high frequency (5000 Hz) Interferential Therapy (INF) for long-lasting pain relief, with Neuromuscular Electrical Stimulation (NMES) for muscle rehabilitation. During the same, uninterrupted treatment session, the RS-4i Plus both excites the body’s natural endorphin production to relieve pain, and provides rehabilitative muscle therapy that reduces muscle spasms, increases circulation, and prevents disuse atrophy.

For patients like Martin, it’s more than a device—it’s a lifeline to feeling more in control, more mobile, and more present for life’s biggest moments.
