Why everything else hasn't worked

Chiropractors help for a day or two — but you can't live at the clinic. Pills mask the pain without touching the cause. A TENS unit only reaches about 8mm deep, so the muscles that actually stabilize your spine never switch back on. The problem isn't on the surface — it's the deep stabilizing muscles your brain has stopped fully signaling.

What's inside the box

  • Reneu™ Device: Dual-channel neuromuscular stimulator with guided intensity
  • Reusable Electrode Pads: Medical-grade, good for dozens of sessions each
  • USB-C Charging Cable + Adapter: 90-min charge, multiple sessions per charge
  • Quick-Start Guide: Simple setup in under 2 minutes

Charge it once. Plug in with the included USB-C cable. A single 90-minute charge powers several sessions.

Place the pads. Stick the reusable pads over your lower back, right where the ache sits, and press the button.

Let it work — 15 minutes. Deep stimulation reaches the stabilizing muscles a TENS unit can't, helping retrain the signal at the source. You just sit back.

I'd tried the heating pads, the chiropractor, a TENS unit that did nothing. My first week with Reneu I actually slept through the night. Mornings are so much easier now.

I'm on my feet all day and by mid-afternoon my lower back was done. Fifteen minutes after work and I'm not dreading the next morning. Dead simple to use.

I'd stopped doing my garden because bending over just wasn't worth it. I'm back out there again. It's a small thing, but it means everything to me.

I bought it for my mom. She figured it out in two minutes and uses it every evening. She keeps telling me how much easier getting up off the couch is now.

The mechanism

The problem usually isn't the muscle. It's the signal reaching it.

Years of pain, sitting, and guarding can quiet the connection between your brain and the deep muscles that stabilize your lower back. When that signal fades, those muscles stop fully switching on — and the everyday support your back relies on gets weaker. A TENS unit only reaches the surface, so it never wakes them up.

Reneu sends a deeper, guided pulse that re-engages those stabilizing muscles — and with a few minutes a day, helps retrain that brain-to-muscle pathway so they start switching on again on their own.

  • Reaches past the surface. Built to engage the muscles underneath, not just the skin a TENS unit sits on.
  • Wakes the deep stabilizers. The quiet muscles that support your lower back every minute of the day.
  • Works by retraining, not masking. A few minutes a day to help the signal hold beyond the session.

The science

The technology isn't new. The way we use it is.

Neuromuscular electrical stimulation — NMES — has been studied for decades. Research has explored how a guided pulse can engage and strengthen muscles, including the deep stabilizers that quietly support the lower back. Reneu is built on that foundation, with one focus: reaching and re-engaging those muscles, at home.

Based on published research into NMES and muscle activation.

The deep muscles around the spine are often underactive. Engaging them through targeted NMES can be a meaningful part of a daily routine for people managing everyday back discomfort.

Why it's different

TENS masks it. Reneu is built to retrain it.

If you've tried a TENS unit, you know the pattern — it tingles, the ache quiets, then you switch it off and it's back. Here's what's actually different.

TENS unit
Surface relief
  • Reaches only the skin, about 8mm deep
  • Blocks the pain signal temporarily
  • Turn it off and the ache returns
  • Nothing changes underneath
Standard NMES
A shallow buzz
  • A single, shallow pulse
  • Often too weak to reach the deep muscles
  • Light surface contraction only
  • Fades soon after the session
The difference
Reneu
Deep retraining
  • Built to engage the muscles underneath
  • Re-activates the deep stabilizers
  • Helps retrain the brain-to-muscle signal
  • Works to build beyond the session
