365-Day Guarantee — Risk Sits With Us

You Own a TENS Unit.
It Failed Because of This.

Your TENS unit targets the sensory nerve. The muscle that controls your flare cycle is on the motor nerve. TENS was never designed to reach it.

Morning Stiffness
Still negotiating the first hour. Every day. Still happening.
Flare Cycle
Feel better, do a normal thing, wake up worse.
Nothing Lasts
Pads on, something happens. Pads off, nothing changed.

The deep stabiliser in your lower back switched off when your back went. Your brain never switched it back on. Your TENS unit cannot reach it. It talks to the wrong nerve.

Your TENS unit floods the sensory nerve with sensation. That is why it feels like it is working.

The muscle that decides whether you have a good day or a bad day is on the motor nerve. A completely different pathway. TENS does not send a signal to it. Not at level 5. Not at level 50.

NMES does.

If You Have Tried These Before

“I did the exercises. I went to physio.”

An NHS home exercise programme sheet beside a resistance band
✕
Those work the muscles that are still listening. The deep stabiliser is not one of them. Motor control exercise alone left multifidus activation unchanged. (Songjaroen et al., 2024)

“I use the gel. I take co-codamol.”

Ibuprofen gel and a part-used blister of co-codamol
✕
Pain management is not muscle activation. The gel reaches the surface. The pills lower the signal. When they wear off, tomorrow morning is still the same.

“I had cortisone injections.”

A clinician giving a cortisone injection
✕
The injection reduces inflammation around the structure. It does not reach the muscle causing the instability. That is why the relief does not last.

All of those manage a symptom. None of them reach the root cause.

The root cause is a deep stabilising muscle that switched off when your back went and never came back on. Without it, your spine has no deep support. That is why the pain keeps returning.

This Is For You If… And Not For You If…

✓ This Is For You
✓You own a TENS unit and your back still goes
✓You are tired of temporary relief that disappears when you remove the pads
✓Your exercises have stopped making a difference
✓You have been told “learn to live with it”
✓You want to fix the root cause, not manage the symptom
✕ Not For You If
✕You want a quick fix that works once and stops
✕You are looking for a miracle cure
✕You are not willing to give it 90 days
✕You think a surface tingle is the same as a muscle contraction
✕You are already on a path that is working

If you checked off anything on the left, you are not the kind of person who accepts “learn to live with it” as a final answer. Lumera was built for you.

1 Device. 5 Advantages.

Every feature has one job. Here is what they do.

Single Butterfly Pad The One-Touch Design
One piece. Both sides of the spine. No reaching behind twice. No aligning separate electrodes.
29 Intensity Levels The Depth Control
Most TENS units have 16. Research confirmed the multifidus contracts only at sufficient intensity.
10 Stimulation Rhythms The Recovery Arc
A muscle offline for weeks needs a gentler signal at first. 10 rhythms from first wake-up to sustained contractions.
Wireless Remote The Control
The pad sits on your back. The remote sits in your hand. Start, adjust, stop. Without reaching behind.
The Palm Test The Proof
Place your palm over the pad. A firm rhythmic squeeze means the deep muscle is working. A tingle means turn it up.

The Short Answers.

How is this different from my TENS unit?

TENS targets the sensory nerve. It masks pain. Lumera targets the motor nerve. It contracts the muscle that stopped working.

What does the WHO say about TENS for back pain?

The WHO reviewed 17 trials and 1,027 patients in 2023. They concluded the evidence “did not support the use of TENS for the routine management of chronic primary low back pain.”

Will this work for stenosis or disc problems?

Your disc is still your disc. But the muscle that protects that part of your spine is offline. That is why the pain keeps coming back. This device wakes it up.

How long before I feel something?

You feel the contraction in the first session. The palm test confirms it. Morning changes start in week 1–3. The full protocol runs 90 days.

Do I need to use it forever?

No. You use it until the muscle fires on its own. Then the device goes back in the drawer because you do not need it.

Is it safe?

NMES has been used in NHS rehabilitation units for decades. Do not use with a pacemaker, implanted electrical device, metal in the lower back, epilepsy, active cancer, or during pregnancy. If unsure, ask your GP.

What if it does not work for me?

Send it back within 365 days. Full refund. Free return postage. You talk to a person.

Is there clinical evidence?

Six peer-reviewed studies. All cited on this page with links. All verifiable on PubMed.

Will this make my back crack weird?

No. You feel a deep contraction, not a manipulation. Rhythmic squeeze, not adjustment.

Lumera is a wireless NMES device designed to stimulate the deep stabilising muscles of the lower back. It does not repair discs, decompress nerves, or treat spinal conditions. Individual results vary. Consult your GP before use. Do not use with a pacemaker, implanted electrical device, metal in the lower back, epilepsy, active cancer, or during pregnancy. Lumera is not the ReActiv8 implantable device; ReActiv8 data demonstrates the clinical principle of targeting the multifidus with electrical stimulation.
