For people whose nerve pain has outlasted everything they've tried
You were told to learn to live with it.Before you do — this takes about ten days to find out.
Scrambler therapy is an FDA-cleared, non-drug treatment for nerve pain. Small electrodes go on healthy skin near the pain — never on the raw, painful spot — and the machine sends a different message up the same nerves your pain has been using. No needles. No medication. Nothing implanted. Nothing to recover from. You lie back for about forty minutes, and most people learn early whether their body is answering it.
You know the exact moment it stopped being a symptom and started being your life.
Maybe it was the chemo — you finished treatment, you were supposed to be celebrating, and your feet never came back. Maybe it was shingles, and the rash cleared months ago but the burning never got the message. Maybe it was something small, a wrist, an ankle, that should have healed in six weeks — and instead the pain spread, the skin changed color, and now a bedsheet is unbearable. Maybe there's no story at all. The neuropathy just arrived, and got worse.
Whatever started it, here's where you are now.
You don't sleep. Not really. You've worked out an arrangement with the night — feet outside the covers, or off the end of the bed, or propped on a pillow, because the weight of a blanket is too much. You know the 3am ceiling well.
You have a shoe collection you can't wear. You've stopped saying yes to things: the standing part of a party, the walk to the restaurant, the trip that involves an airport. You've had the conversation with the people who love you where you can see them deciding whether to believe how bad it is.
And you have a list. Gabapentin, and the fog that came with it. Lyrica, and the weight. Amitriptyline. Cymbalta. The nerve blocks that worked for six days. The steroid that worked for two weeks. Maybe opioids, which took the edge off and took some other things too.
Somewhere on that list, a specialist told you the sentence you carry around now: there's nothing more we can do — you'll have to learn to live with it.
Here's what that sentence actually meant: we've run out of tools. The specialist who said it was telling the truth — about their own toolbox. They had almost certainly never seen a scrambler machine, because there aren't many, and nothing about the way medicine is organized would have put one in front of them. Their dead end was the end of their equipment — not the end of your options. The rest of this page is about the tool they didn't have.
The mechanism
How it works — in plain words
Start with what's actually wrong.
With most pain, the nerve is a messenger doing its job — you sprain an ankle, the ankle sends a message, the message is true. Nerve pain is different. The tissue may have healed. The chemo ended two years ago. The shingles rash is long gone. But the nerve keeps firing, and the spinal cord and brain keep listening, and the whole circuit gets better and better at sending a message that isn't warning you about anything anymore. Pain becomes the habit rather than the alarm.
That's why the usual tools underperform here. A pill that lowers the volume doesn't change the message. A block that numbs the line wears off, and the line comes back. The problem isn't only where it hurts — it's the pattern being sent and re-sent.
Scrambler therapy goes after the message.
Small adhesive electrodes — the kind used for an EKG — are placed on healthy skin around the painful area, on the nerve pathways that feed it.2 Never on the raw spot. Never on broken or numb skin. The whole idea depends on finding nerves that still work well enough to carry a signal.
The machine then sends its own signal up those nerves. It isn't a buzz and it isn't random. The device builds sequences of waveforms, changing constantly, shaped to imitate the traffic a healthy nerve sends when nothing is wrong.2 Your nervous system receives a non-painful message on the same line that has been carrying pain — over and over, for about forty minutes.
While that's happening, most people feel their pain drop in the room. That's the point of a session: the pain in that area is replaced, during treatment, by a mild tingle. Then you go home, and the question becomes how long it holds — which is what the next ten days answer.
The question everyone asks
"Isn't this just a TENS unit?"
Ask this. Everyone should ask this — the electrodes look identical, and TENS units are sold for $40 online.
The straight answer is that they're different treatments that happen to share a sticker. The same NEJM review is explicit that scrambler therapy is not a version or a subcategory of TENS.2 Three differences matter to you:
A TENS unit is built to be adjusted by you, at home. This machine isn't.
Its output is generated by the device's own program — the settings that shape the signal can't be turned up or invented by the operator. What the operator controls is where the electrodes go and how strong the sensation is, guided by what you say you feel.
TENS relief is designed to work while it's on.
For most people it fades within minutes to hours of switching it off. Scrambler therapy is given as a course of sessions, specifically because it aims at relief that outlasts the session.
You can't do it at home.
The device is restricted to use by physicians, or by trained personnel under a physician's supervision. That restriction is a feature — it's why "I tried a TENS unit and it did nothing" tells you nothing about how you'll respond to this.
If you tried a TENS unit and got nothing, that is genuinely not evidence about this.
What to expect
What a session is actually like
You keep your clothes on. You sit or lie back in a treatment room — no gown, no straps, nothing to climb into.
Someone places the electrodes. This is the part that takes skill, and it's done by hand, patient by patient: the pads go on healthy skin along the nerve pathway that serves the painful area, above it and around it. If the first placement doesn't do the job, they come off and go somewhere else.
Then the level comes up slowly, one channel at a time, and here is the only thing you have to do: tell the truth about what you feel. The operator raises it in small steps and keeps asking — first tell me when you feel something, then tell me when it's enough.2 You are the instrument. The target is a clear tingle that's completely comfortable — people describe it as fizzing, a light buzz, or, in the phrase the published description uses, like being bitten by tiny electrical ants.2
Then the session runs about forty minutes.4 People read, scroll, nap, talk.
Here's the part we are most deliberate about: we don't put the pads on and walk away. Someone is with you for the session. We keep checking what the pain is doing, and if a placement isn't getting the answer we want, we change it — in that session, not next week. The goal we work toward in every single session is your pain at zero while you're on the table. Not lower. Zero, or as close to it as your body will go that day. When that isn't happening, it means we haven't found the right setup yet — so we keep working.
When the session ends, the pads come off and you drive yourself home. Nothing to recover from, no drowsiness, no restrictions. The next day, you do it again — and the placement is worked out fresh, because skin and nerves aren't the same from one day to the next.
A different protocol for a different problem
If you have CRPS, read this part
CRPS is not like the other nerve pain we treat, and we don't run it like the other nerve pain we treat.
You already know the part that makes it different. The limb has become so sensitive that the pain feeds itself — a sleeve, a breeze, the sheet, and the whole system escalates. So you protect it. You stop moving it, stop letting anything touch it, stop looking at it. Every one of those choices is completely reasonable, and every one of them teaches the nervous system that the limb is dangerous.
Scrambler therapy interrupts the pain signal. On its own, that leaves the rest of the pattern in place. So for CRPS patients we use a protocol we've built specifically for them, out of what we've learned treating this condition:
We start desensitizing almost immediately.
Once the pain is down during a session, there's a window where the limb can be touched — and that's exactly when we start using it. Gentle, graded contact with the skin, beginning with whatever the limb will accept and building from there. Doing this while the pain is quiet, instead of asking a flaring limb to tolerate it, is the whole idea.
We use mirror therapy during treatment.
A mirror is set up so the healthy limb's reflection sits where the painful limb is. The brain gets to watch a limb that moves normally and doesn't hurt. It sounds strange the first time it's described; it's a well-established approach in this condition, and pairing it with a session where the pain is already down gives the brain a much better picture to work with than it has had in years.
And we keep changing the approach until we get the answer.
Electrode placement, the level, the sequence, what we add and when — we try different protocols across the course rather than repeating the same setup ten times. Getting your pain to zero during the session is the target every day.
All of it is part of the protocol. The desensitizing work and the mirror therapy aren't add-ons and they aren't billed on top of anything — they're how a CRPS course is run here.
And it isn't only for CRPS. This is where we use it most, because CRPS is where the pattern is hardest. But if your pain is stubborn against the scrambler sessions alone — shingles pain that won't let go, phantom limb pain, any nerve pain that isn't answering the way it should — we use whatever part of this helps. The point isn't the protocol. The point is getting your pain down, and we'll use everything we have to do that.
If you're weighing this against a spinal cord stimulator: nothing here is implanted, nothing has to be surgically removed later, and it doesn't close any door. It's the kind of thing worth finding out about before a decision that can't be undone.
The nerve pain we see most
If you have peripheral neuropathy — from chemo, diabetes, or anywhere else
The feet that never came back after chemotherapy ended. The burning and pins-and-needles of diabetic neuropathy. The "walking on gravel" feeling that arrived on its own and settled in. Peripheral neuropathy is the nerve pain we see most — and it's precisely the kind of stuck signal the mechanism section above describes.
If the medications have only ever lowered the volume — or traded relief for fog — this goes after the message itself. And you don't have to take that on faith: a $19 consultation and a $99 session tell you what your own nerves do with it.
The course
Ten days — and an early answer
A full course is ten sessions, on consecutive weekdays — five days a week for two weeks.4 That's the protocol the device is built around, and it's the one the published work uses.
Ten days in a row is a real commitment, and we'd rather you hear it now than discover it after you've committed to it. If you're driving in from out of town, plan for two weeks in San Antonio. It's also why we run scrambler sessions on Fridays, when the rest of the clinic is closed — a ten-day course doesn't fit a four-day week.
But you don't decide about ten days on day one. That's the part that matters if you've been burned before. Here's how it actually goes:
- First, a $19 consultation. We take the history, look at what you've been diagnosed with and what you've already tried, and go through the list of reasons someone can't have this treatment (it's further down this page — read it before you come). If you're not a candidate, the $19 got you a straight answer and a direction.
- Then a $99 first session — credited toward the course. A full session, run properly, at a price meant to make the question answerable rather than expensive. Most people get useful information from that one session about whether their body is responding. If you continue, the $99 comes off the price.
- Then you decide. If there's a signal, we talk about the full course, and you'll know what it costs before you commit to anything. If there's nothing — no change during the session, nothing after a few sessions — we say so, and we stop. We are not going to run you through ten sessions of something that isn't working in order to finish the program.
What "working" tends to look like
For people who respond, relief usually builds over the course rather than arriving all at once — each session's relief tends to last a little longer than the last.2 The published reports describe relief lasting weeks, months, and in some cases longer after a course ends. They also describe people whose pain comes back and who respond again to a short round of booster sessions — usually a couple of days rather than another full course.
Weigh it against the alternative
The case for trying this first
Weigh what it asks of you against what you've been offered. No medication, and nothing to wean off. No implant, no leads under your skin, no surgery to place a stimulator. No nerve block, no infusion. No downtime — you sit in a chair for about forty minutes and drive yourself home.
Why this works
Why this works — and what we stand behind
Scrambler therapy retrains the pain signal instead of masking it. Here's what makes it work here, and what you can hold us to.
Your first session answers the most important question. The fastest way to know whether your nerves respond is to treat them. That's exactly why the first full session is $99 and counts toward the course — you see what your own body does with it before you commit to anything.
It works on the signal, so the cause gets its own attention. If something underneath the pain can be treated, we make sure it is — and if it needs someone other than us, we tell you who.
Some patients come back for a booster. For many people relief holds for a long stretch. If some of it returns, a short booster is usually all it takes, and we'll tell you what to watch for.
Who runs it matters. Everything depends on where the electrodes go and whether the level is set by someone paying attention to your answers. Dr. Barton trained in the protocol in Rome under the direction of the inventor, Giuseppe Marineo — and every course here runs under the medical supervision of Lisa D. Persyn, M.D.
Candidacy
Who this is for — and who it's not for
What it's used for
Scrambler therapy is used for nerve pain — pain caused by a problem in the nerves themselves, rather than pain from a joint or a muscle. The conditions we see most:
- CRPS / RSD — burning, color and temperature changes, a limb that can't stand to be touched
- Chemotherapy-induced peripheral neuropathy — the feet and hands that never came back after treatment ended
- Shingles nerve pain (postherpetic neuralgia) — the rash healed; the burning didn't
- Diabetic and other peripheral neuropathy — burning feet, pins and needles, the "walking on gravel" feeling
- Phantom limb pain
- Nerve pain after surgery or injury — including pain along a scar, and radiating pain that stayed after a back or neck operation
Who cannot have this treatment
These are absolute. They come from the device's own instructions, and no exam changes them:4
- An implanted pacemaker or defibrillator
- A spinal cord stimulator or peripheral nerve stimulator, implanted or in trial
- Aneurysm clips, vena cava clips, or skull plates
- A seizure disorder — epilepsy, or a tendency to seizures
- Pregnancy — the treatment hasn't been studied in pregnancy, so it isn't used
- Undiagnosed pain — pain nobody has worked up yet needs a diagnosis first, not a treatment. If that's where you are, we'll help you get to the right person.
Where we take extra care
Heart problems, diagnosed or suspected — we talk to you about it, and there are placements we don't use. Skin that has lost normal sensation, or is broken, infected or fragile where pads would go. A tendency to bleed or bruise easily, or a recent fracture. Some anticonvulsant medications can change how the course is run — bring your full medication list to the consultation. And occasionally, skin irritation where the pads sit: it's the most common side effect there is, and moving the placement usually solves it.4
Cost & insurance
What it costs — and what you get for it
Most nerve-pain patients have already spent a great deal on things that didn't work. So we built the front end around one question: does this work for you?
The consultation is $19.
History, examination, a real conversation about whether this is the right treatment for your problem, and the candidacy screen above. If the answer is no, we tell you at the consultation.
A first full session is $99 — and it counts toward the course.
Not a demo, not five minutes — a full session, run properly. It exists so you can find out what your nerves do with this treatment before you're asked to commit. Continue with a course and the $99 comes off it.
The full course is an investment we quote in person.
Scrambler therapy isn't a covered insurance benefit, so the course is an out-of-pocket investment — and you'll know exactly what it is, in writing, after your first session and before you agree to anything. If your situation is unusual — a workers' comp claim, or a plan that has covered it before — tell us at the consultation and we'll check what's possible.
Your care team
Who does the treatment
If you take one practical thing from this page, take this: with scrambler therapy, who is holding the electrodes matters as much as the machine. Results follow placement and the care taken in setting the level. The same device in two sets of hands is genuinely two different treatments — which is why every experienced patient community says some version of ask who's actually doing it.
So here's our answer, before you ask.
Kevin S. Barton, D.C. has practiced in San Antonio since 2003. He manages the scrambler program, and he does the treatments.
He completed advanced scrambler therapy training in Rome, Italy, with Dr. Giuseppe Marineo — the biophysicist who invented this treatment.5 Not a weekend certification from a distributor. Training with the person whose research created the device. There are not many providers in the United States who can say that, and there is exactly one in San Antonio.
The program is medically supervised by Lisa D. Persyn, M.D., who is board certified in Physical Medicine and Rehabilitation — the specialty built around restoring function to people living with pain and nerve injury. That matters for two reasons. It's how this treatment is meant to be delivered: the device is restricted to physicians, or to trained personnel working under a physician's supervision.1 And it means your care is being looked at by a physiatrist as well as by the doctor running your sessions.
What that looks like in the room: placement worked out fresh at every visit rather than copied from yesterday's notes; the level brought up in steps with you saying where it stops; the setup changed on the spot when the pain isn't answering; someone with you for the session rather than a machine left running; and the willingness to say, out loud, "this isn't doing what it should — let's stop."

Questions patients actually ask
Before you call
How soon will I know if it's working?
Often during the first session — many people feel the pain fall in the room. But one good session isn't the whole answer; what matters is whether relief starts holding longer between visits. That's usually clear within the first several days, which is exactly why we'd rather you put $99 into finding out than commit to a full course on hope.
Does it hurt?
No. A properly run session feels like a comfortable tingle — often described as tiny electrical ants. If anything increases your pain, we stop and change the placement. A scrambler treatment that hurts is being done wrong.
How many sessions?
A full course is ten, on consecutive weekdays over two weeks. Some people need fewer. Some come back later for a short round of boosters.
Is it covered by insurance?
Almost never — here or anywhere. It's a cash-pay treatment in nearly every clinic that offers it. If your situation is unusual, tell us at the consultation.
Can I still take my medications?
Keep taking them for now, and don't stop anything on your own. Gabapentin, Lyrica (pregabalin) and Cymbalta (duloxetine) can all interfere with the signal scrambler therapy sends, so we'll work with the doctor who prescribed them to wean you off safely. That has to be done gradually: gabapentin and Lyrica are anticonvulsants, and stopping them all at once can cause seizures. Cymbalta can cause withdrawal symptoms if it's stopped suddenly. Bring your full medication list to the consultation.
I have a spinal cord stimulator. Can I do this?
No. An implanted stimulator, a pacemaker or a defibrillator rules this treatment out. If you're considering a stimulator but haven't had it implanted, that's worth talking about before you decide — this is a treatment people often want to try first, precisely because there's nothing to implant and nothing to remove.
I've already had spine surgery — rods, screws, a fusion. Does that disqualify me?
No. Orthopedic hardware — plates, screws, pins, cages, joint replacements — doesn't rule out scrambler therapy. Implanted electronic devices do.
I tried a TENS unit and it did nothing. Why would this be different?
Because they're different treatments that happen to use similar stickers. TENS relief is designed to last while the unit is running. Scrambler therapy is given as a course, aiming at relief that outlasts the session, and its signal is generated by the device's own program rather than dialed in by the user. Your TENS experience genuinely doesn't predict this one.
Who actually does the treatment — and is a doctor involved?
Dr. Barton runs the sessions himself. He completed advanced scrambler therapy training in Rome with Dr. Giuseppe Marineo, the biophysicist who invented this treatment, and the program is medically supervised by Lisa D. Persyn, M.D., who is board certified in Physical Medicine and Rehabilitation. You won't be handed off to a technician, and nobody is left alone with a machine running.
I have CRPS. Is this the same treatment everyone else gets?
No. For CRPS we use a protocol we've built for this condition: the scrambler sessions, plus desensitizing work started early — while the pain is down during a session, which is the window where the limb will tolerate being touched — plus mirror therapy during treatment. We also change the approach across the course rather than repeating one setup ten times. Read the CRPS section above before you come in.
What if it doesn't work for me?
Then we tell you, and we stop. You'll have invested $19 and $99 to get an answer instead of years of wondering — and we'll be straight with you about what else is worth trying. If it does work and you continue, that $99 comes off the price of the course.
