Spine Surgeon Admits: There is one muscle we were never trained to check — and it is why most back surgeries fail

Board-certified spine surgeon breaks his silence on why so many spinal fusions and laminectomies fail to give patients lasting relief — and the 15-minute at-home protocol reactivating a muscle 93% of surgical patients lose after their operation.

I do not take writing this article lightly.

For 18 years, I have performed spinal surgeries.

Fusions. Laminectomies. Microdiscectomies.

Complex multi-level procedures at some of the most respected hospitals in the northeast.

I have been trained by the best. I have trained others. I have testified in court as an expert witness on spinal biomechanics.

Everything I am about to tell you contradicts what I was taught in medical school.

It contradicts what I was trained to say to patients in my consultation room.

It will make me unpopular with a number of my colleagues.

But I do not have the option of staying silent anymore.

Not after what happened to my sister.

If you have been diagnosed with spinal stenosis and your surgeon says surgery is "your only option"...

If you have already had a fusion or laminectomy and you are STILL in pain months or years later...

If your back feels like it collapses under you every time you stand up from a chair...

If you have tried physical therapy, injections, TENS devices, bracing, and pills — and nothing has held for more than a few weeks...

Please read the next 8 minutes carefully.

Because what I discovered — after 18 years inside operating rooms — could save you from a surgery you do not need.

Or explain why the one you already had never gave you the relief you were promised.

The Phone Call From My Sister

It was 11:14 PM on a Tuesday last October.

I was in my study reviewing a case file when my phone rang.

My sister Kate.

She is 62 years old. Retired school psychologist.

Two grandchildren. Lives about 40 minutes from me outside Boston.

Kate had spent 30 years working in inner-city schools before her retirement.

She had taken evening Italian classes for almost as long

— six months a year, at a community college, saving toward one specific plan.

She and her husband David had booked a three-week trip to Italy for October 2024.

Rome, Florence, and a small town in Tuscany where she had wanted to walk the same hills her grandmother's family had come from.

Fourteen months earlier, she had undergone L4-L5 fusion for chronic spinal stenosis.

Not by me — surgeons do not operate on immediate family, it is a boundary I have always respected.

The procedure was performed by one of my most trusted colleagues at a hospital I have privileges at.

Textbook surgery.

Clean decompression. Hardware placement I would have signed off on myself.

Kate had spent the first six months of recovery doing everything right.

She followed the physical therapy protocol.

She showed up to every follow-up.

She listened to her surgeon.

By month six she was better.

By month ten she was worse than the day before the surgery.

When I answered the phone that night, she was crying.

Not a small cry.

The kind of crying you do when you have been holding it in for weeks and can no longer manage it alone.

She said: "Michael, I have been sitting at the kitchen table for two hours staring at my old MRIs. Your name is on my referral notes. Please help me. Why am I in worse pain now than before the surgery?"

I did not have an answer.

Not one that would help her.

I could quote her the recurrence statistics. I could explain adjacent segment disease.

I could recommend she come in for another consult and get new imaging.

What I could not do was tell her, honestly, why the surgery had failed.

Me. Her older brother. Eighteen years in spine surgery. Board-certified. Twelve peer-reviewed publications.

And I could not tell her why her back was worse than before we opened it up.

Something in me broke that night.

Because if I could not help my own sister

— after everything I had trained for —

then how many other Kates had walked out of my consultation room over the last 18 years with the same story I was about to be part of?

The Calls That Came After

The phone call at 11:14 PM was not the only one that month.

Two weeks later, Kate called me on a Sunday afternoon. She had been trying to get out of the reclining chair in her living room.

Her 8-year-old granddaughter Emma had been sitting next to her, coloring at the coffee table.

Emma had stood up, put her small hands under Kate's forearm, and said "Grandma, I'll help you."

Kate let her.

Because she could not get up on her own.

When Kate called me an hour later, she said the thing that has stayed with me longer than anything else in this story:

"Michael, I have spent my entire career helping other people's children. Now I am asking mine to help me stand up. This is not the life I earned."

Two weeks after that, Kate's original surgeon — my colleague — brought up the word "revision."

Not aggressively. Just conversationally.

That if things did not improve within 6 months, they should start discussing a second procedure.

Kate called me that night. She was calmer this time. Which somehow made it worse.

She said: "Michael. The first surgery made my life smaller. What if the second one takes what's left?"

She was not being dramatic.

She was asking the exact question the peer-reviewed literature quietly answers with a 22% "worse-after-revision" rate and a 45% "no meaningful improvement" rate.

I had been the surgeon in that consultation seat a hundred times before, telling patients the odds "were in their favor."

I had never before had to sit on the other side of it and hear my sister ask me if the next operation was going to be the one that finally erased her.

That was the week I started the research.

The Four Months That Changed Everything I Believed About Spinal Surgery

For the next four months, I barely slept.

I pulled every peer-reviewed post-surgical outcome study I could find.

I cornered rehabilitation specialists at the hospital I had never bothered to speak with before.

I flew to a spinal rehabilitation conference in Denver on my own dime.

What I found made me sit down at my desk and stare at the wall for a long time.

The research existed. But most of it lived in rehabilitation medicine journals I had never read.

My surgical training had prepared me to fix bones and discs — not to reactivate the muscle that sat above them.

And the piece that finally connected everything for me had only been published a few months earlier.

In late 2025, a major systematic review and meta-analysis on restorative neurostimulation for multifidus dysfunction was released

— showing sustained pain reduction of over 3 to 4 points on standard clinical scales, and quality-of-life improvements maintained up to 4 years later.

It was the first time the multifidus had been formally recognized in the mainstream literature as a central driver of chronic low back pain outcomes

— not a peripheral finding, but the root cause the entire surgical protocol had been designed around while ignoring.

I had operated on spine patients for 18 years without knowing this.

Everything I had been taught to believe about failed back surgery was incomplete.

Here is what 18 years of surgical training never taught me:

These are not the surgeon's numbers. These are the protocol's numbers.

Which is what made me the most uncomfortable of all — because I have been part of that protocol my entire career.

Here is what nobody told me during residency, fellowship, or any of the continuing medical education courses I have taken since:

The reason so many spine surgeries fail long-term is not bad surgeons.

It is not defective hardware.

It is not "adjacent segment disease" — which is often just what we call the problem when we cannot explain it.

The reason is a muscle.

One muscle.

A muscle sitting just 3 centimeters beneath the skin of your lower back.

A muscle nobody checks before surgery.

A muscle nobody rehabilitates after surgery.

A muscle that, in the vast majority of post-surgical patients, has completely shut down — and stays shut down without a specific type of intervention.

It is called the multifidus.

And it is the single most important muscle in your entire lower spine.

The Root Cause I Was Never Trained To Look For

Your spine has 33 vertebrae.

They do not simply stack on top of each other.

They are held in place by a deep muscle that runs the length of your spine like an internal brace — the multifidus.

Every step you take, every time you bend, every time you turn — this muscle fires thousands of micro-contractions per minute to keep your vertebrae aligned and absorb the load from your upper body.

It absorbs roughly 60% of the compressive force on your lower back.

When it works, your spine holds itself up.

When it stops working, your body weight collapses directly onto your discs and your nerves.

Here is what happens when you have spinal stenosis, a disc problem, or any spinal surgery:

Your nervous system does something protective.

It interprets the pain or the surgical trauma as a signal that your spine is unstable

— and it responds by cutting the neural signal to the multifidus.

Researchers call this phenomenon Core Muscle Lockout.

The brain sends a signal that essentially says: "Stop firing. You are making it worse."

And the muscle obeys.

Within 48 hours of spinal trauma or surgery, the multifidus can lose up to 80% of its function. It atrophies. It shrinks. It goes silent.

And here is the part that shook me the hardest when I read the research:

It does not come back on its own.

Not with rest.

Not with physical therapy.

Not with the standard post-surgical protocol I had been recommending to my patients for 18 years.

Not with yoga, pilates, swimming, or any "core strengthening" program.

Because the muscle is not weak.

It is locked.

You cannot strengthen a muscle that is not receiving a signal from the brain.

And every stenosis patient I have operated on in 18 years has walked into my consultation room with this muscle already offline — often for years — before we ever discussed surgery.

Then the surgery itself made it worse.

Why Every Treatment You Have Tried Has Only Given You Temporary Relief

Read this section carefully. Once you understand this, you cannot unsee it.

Every treatment protocol in mainstream medicine for chronic back pain fails for the same underlying reason.

Physical therapy strengthens the surface muscles around the spine. It does not — and cannot — reactivate the multifidus.

The brain has cut the signal. You cannot voluntarily contract a muscle the nervous system has switched off.

That is why you felt "a little better" for a few weeks and then got worse again.

TENS units reach 5 to 8 millimeters deep. They block pain signals at the skin level. Your multifidus sits 30 to 50 millimeters down.

A TENS unit cannot come close to reaching it. It is like trying to jump-start a car engine by tapping on the hood.

Epidural injections reduce inflammation around the nerve. They do nothing to reactivate the muscle that was supposed to stabilize that nerve in the first place.

That is why the first shot lasts six months, the second lasts three, and the third barely lasts six weeks.

Spinal fusion and laminectomy fix the bone.

They completely ignore the muscle.

Patients come out of surgery with textbook hardware placement and a multifidus that has been shut down for so long it has atrophied

— and now, additionally, has been damaged by the surgical retraction required to access the spine. The bone is repaired.

The foundation muscle is more offline than before we started.

Chiropractic adjustments temporarily shift alignment. The locked multifidus cannot hold the new alignment.

By the time the patient reaches their car, the spine has drifted back to where it was.

None of these interventions unlock the multifidus.

Not one.

You cannot do it with stretching. You cannot do it with strengthening. You cannot do it with medication, injection, or scalpel.

There is exactly one intervention that has been clinically demonstrated to force a locked multifidus back online.

And it took me four months of research to find it.

The One Thing That Actually Reactivates The Multifidus

It is a technology called NMES.

Not TENS. NMES.

Neuromuscular Electrical Stimulation.

The two are often confused. They are completely different technologies.

TENS sends weak electrical pulses to the surface of the skin to block pain signals. It reaches 5 to 8 millimeters deep. It buzzes. It distracts.

NMES sends targeted electrical signals 30 to 50 millimeters deep — directly into the muscle tissue — forcing muscle fibers to contract.

It bypasses the nervous system's "off" signal completely.

It does not ask the multifidus to fire.

It makes it fire.

Contraction after contraction. Over consecutive sessions, the neural pathway between brain and muscle rebuilds.

The brain begins to receive the signal again. The muscle begins to fire on its own — even when the device is off.

NMES has been used in elite sports medicine and post-surgical rehabilitation for 40 years.

It is how Olympic athletes recover from spinal injuries in weeks instead of months.

It is how NASA astronauts prevent muscle atrophy in zero-gravity conditions.

And until recently, it was only available inside clinical settings at $300 per session — requiring specialist referrals and months of waiting.

That is what I told Kate that Sunday night after four months of research.

She had one question: "Michael, can we get this at home?"

Until recently, the answer was no.

The Device I Gave My Sister

The device is called the ReliveX Adaptive Correction System.

It is the first at-home NMES device specifically calibrated to reach the multifidus at the exact depth research has identified — 30 to 50 millimeters.

I spent weeks reviewing the technology before I was willing to recommend it to my own sister.

I evaluated the pulse parameters. I looked at the FDA clearance documentation.

I compared the specifications against the clinical-grade NMES units I have used in hospital rehabilitation settings.

What convinced me was this: ReliveX does not just stimulate the muscle.

It combines two therapeutic actions in a single 15-minute session — decompression and muscle reactivation working simultaneously.

Here is what each phase does:

Phase A: Decompression. The moment the device turns on, the electrical pulses trigger gentle, rhythmic contractions in the deep stabilizing muscles along the spine.

Those contractions pull the vertebrae apart from the inside. Pressure lifts off the discs.

Pressure lifts off the compressed nerves. It mimics what a clinical decompression table does — except from the inside out.

Most patients feel it within the first two minutes. A deep "opening" sensation in the lower back. That is the decompression phase working.

Phase B: Re-Education. While Phase A is creating space, Phase B is forcing the multifidus to fire. Contraction after contraction.

Over 30 days of consistent use, the neural pathway between brain and muscle rebuilds itself.

This is not a one-session miracle. This is neurological rehabilitation. The brain "remembers" how to use the muscle.

The muscle starts firing on its own again — even when the device is turned off.

This is how you rebuild what I now think of as the Natural Internal Brace of your spine.

Total session time: 15 minutes.

The device auto-shuts off at 15 minutes by design.

Because that is the optimal window for muscle reactivation without overworking the tissue.

What Happened To Kate

Kate started using ReliveX in late November 2024.

I need to be honest with you — I did not tell her to expect miracles.

I told her the research suggested a 30-day reactivation window and that we would evaluate her progress week by week.

She started her first session at her kitchen table.

She placed the pads on either side of her lower spine and pressed the button.

She called me the next morning.

She said: "Michael, I felt something in my back last night that I have not felt in three years. It was not a buzz on my skin. It was inside."

That was the multifidus firing for the first time.

"By week four, my sister called me from her back garden. She had spent three hours pulling weeds. She had not done that since 2022. She was crying, but this time for a different reason."

By week six, Kate had returned to the bookclub she had stopped attending 18 months earlier because she could not sit through the discussion.

By week ten, she had gone with her husband to their granddaughter's dance recital and stood at the back of the auditorium for the entire program. Something she had not done since before the surgery.

At her 12-week follow-up with her original surgeon — my colleague — he looked at her imaging and asked what she had been doing differently. She told him.

He took notes.

He asked her to send him the research citations.

In April 2025, Kate and David rebooked the Italy trip they had cancelled a year earlier. They flew out in June. Three weeks. Rome, Florence, and the town in Tuscany where her grandmother's family had lived.

She sent me a photograph the day they arrived in the Tuscan hills. She was standing on a stone path outside a small stone church.

She had walked there. On her own. Emma's hand was in hers in the photo — Kate had insisted on bringing her granddaughter along.

She wrote on the message: "Michael. I earned this. Thank you for not giving up."

That was the moment I decided to write this article.

Because if Kate's story was reproducible, other patients deserved to know.

What The Broader Patient Data Shows

Over the last 24 months, more than 140,000 patients have used the ReliveX Adaptive Correction System.

The reported outcomes from user data:

These are not clinical trial numbers. They are self-reported user outcomes.

But they are consistent with what I saw in my own sister.

Which is what matters most to me — not because Kate is famous or exceptional, but because Kate is 62 years old and had a "failed" surgery,

and by every marker of clinical protocol, she should not be walking three miles a day at this point.

And yet she is.

Here is what other users are reporting:

What Treating Chronic Post-Surgical Back Pain Actually Costs

Let me show you what treatment protocols cost in the United States today.

Physical therapy route: 24 sessions (twice per week for 12 weeks) at an average of $185 per session — $4,440. And in most cases, a multifidus that is still locked.

Pain management route: Initial consultation, imaging, and epidural injections (typically 3 to 6 per year, ongoing) — averaging $8,600 per year for temporary relief that lasts 6 to 12 weeks per injection.

Revision surgery route: L4-L5 fusion revision runs $65,000 to $120,000, requires 3 to 6 months of recovery, has a 45% chance of not resolving the pain, and a 22% chance the patient is worse afterward.

These numbers are not designed to alarm you.

They are the standard cost structure of chronic back pain management in the American healthcare system.

I have participated in this system for 18 years.

Which is what makes this next number the one I find hardest to reconcile.

The ReliveX Adaptive Correction System

Comparable clinical NMES systems used in hospital settings cost between $1,000 and $2,500.

The regular retail price of the ReliveX Adaptive Correction System is $199.95.

Today it is available at 50% off — $99.95.

Less than a single physical therapy session.

Less than one month of Gabapentin.

Less than the co-pay on most epidural injections.

The 90-Day Reactivation Guarantee

I understand skepticism.

As a surgeon, I have watched patients spend money on unproven devices for 18 years.

I would not recommend this if it did not have a full guarantee behind it.

Use the device for 90 days. 15 minutes a day.

If you do not feel your multifidus reactivating — the deep pulse, the opening sensation, the increased stability — send it back.

Full refund. No forms. No "store credit." No interrogation.

The reported refund rate is 0.4%. Four patients per thousand.

That is the number that convinced me the outcomes were real.

The Choice You Are Facing Right Now

If you have been diagnosed with spinal stenosis, or you have had a failed spinal surgery, you are at a decision point.

You can continue with the current protocol.

More physical therapy. More injections. Another consultation about a second procedure.

That is the path I have been referring patients into for 18 years.

Or you can spend $99.95 on a device that reactivates the muscle every one of those interventions was designed around but never addressed.

I am not asking you to trust me because I am a surgeon. I am asking you to trust the mechanism.

The multifidus is real anatomy. Core Muscle Lockout is documented in the peer-reviewed literature.

NMES is a 40-year clinical technology.

What has changed is that it is finally available for use in your own home for a fraction of what it costs inside a hospital.

One Last Thing

I did not want to write this article.

I have colleagues I respect who will not be happy about it.

I have hospital leadership who will read it and have opinions.

But I am writing it because my sister is 62 years old and walked three miles yesterday,

and 14 months earlier she was crying on a kitchen chair asking me why she was in worse pain than before the surgery I sat in a consultation room and recommended.

I owe her that letter. And I owe it to every patient whose fusion did not give them the relief we promised.

You have every reason to be skeptical. Try the device with the 90-day guarantee in place. If it does not work, you have lost nothing.

If it does, you will understand — as my sister does now — that the missing piece of your back pain treatment was never a bigger surgery.

It was a muscle that had been offline the entire time.

In service of better outcomes,

Dr. Michael Cohen, MD
