TRANSCRIPT TEXT:
At Vertrae®, a spine-only practice in Dayton, Ohio, we work with patients every day who are trying to understand whether spinal cord stimulation, or SCS, might be the right path for them. For many people, this conversation comes after months or years of chronic pain, multiple treatments, and a lot of frustration. It is normal to have questions. It is normal to feel skeptical. And it is normal to wonder whether this is just another treatment that may or may not help.
That is why clear information matters. Spinal cord stimulation can sound intimidating when it has not been explained well. Patients often come in worried that it means they are out of options, or that they are being asked to commit to something permanent before they know whether it works. In reality, the process is much more thoughtful, more testable, and more patient-centered than many people expect. Today, we are answering some of the most common questions patients ask about spinal cord stimulation.
The first question is usually: Is spinal cord stimulation a last resort? At Vertrae®, the answer is no. SCS is not simply an end-of-the-road option for patients who have run out of hope. It is an evidence-based therapy for a specific type of pain, most often neuropathic pain, which means pain related to irritated, damaged, or misfiring nerves. This is the burning, shooting, electric, radiating type of pain that may travel down the leg, persist at rest, or continue after other treatments have not provided enough relief.
For the right patient, spinal cord stimulation is not a desperate measure. It is the right tool for the right kind of pain. The key is determining whether your pain pattern fits what SCS is designed to treat. That requires a careful evaluation of your history, symptoms, imaging, prior treatments, and goals.
The second question is: How does spinal cord stimulation actually work? SCS involves placing very thin wires, called leads, in the epidural space near the spinal cord. These leads deliver gentle electrical pulses that help interrupt or modulate pain signals before they reach the brain. One way to think about it is that the therapy intercepts the pain message before the brain fully processes it.
That distinction is important. Spinal cord stimulation does not directly fix a structural problem in the spine. It does not remove arthritis, repair a disc, or decompress a nerve that is actively being pinched. Instead, it changes how the nervous system carries and processes pain. The effect is neurological, not pharmaceutical, and it can be especially helpful when chronic nerve pain remains after other reasonable treatments have been tried.
The third question is: Can I try it before committing to a permanent implant? Yes — and this is one of the most important features of spinal cord stimulation. Before a permanent system is placed, patients typically go through a temporary trial. This trial allows you to test the therapy in real life, during your actual daily routine, before deciding whether to move forward.
During the trial, temporary leads are placed in an outpatient setting and connected to a small external generator, usually worn on a belt or clothing. For several days, often about a week, you go home and live your normal life as much as possible. You test the therapy while walking, sitting, sleeping, standing, and doing the movements that typically trigger your pain. The goal is to see how your own body responds in the real world.
If the trial provides meaningful pain relief and functional improvement, you and your physician can discuss whether a permanent implant makes sense. If it does not provide enough benefit, the temporary leads are removed. Nothing permanent has been implanted, and you still gain valuable information about whether this therapy is right for you.
The fourth question is: What does the trial feel like? It is completely normal to feel nervous before any new procedure. Most patients find the trial easier than they expected. The temporary leads are placed during a brief outpatient procedure, often using local anesthesia and light sedation to help keep the patient comfortable.
Traditional spinal cord stimulation may create a mild tingling or buzzing sensation in the area where the pain used to be. This is called paresthesia. Some patients like that sensation because it helps replace the pain signal. However, many newer systems use waveforms that can provide pain relief with little or no tingling at all. In those cases, patients may not feel the device working — they may simply notice that the pain is more manageable.
For some patients, the trial is the first time in a long time that they feel real hope. When someone has lived with chronic nerve pain for months or years, even a meaningful reduction in discomfort can be life-changing. The trial helps make that possibility concrete.
The fifth question is: Can the system be removed if I change my mind? Yes. Spinal cord stimulation is considered a reversible therapy. The permanent system includes the leads and a small implanted generator, and both can be removed if the therapy is no longer needed, no longer effective, or if the patient chooses to discontinue it.
That reversibility matters. It makes SCS fundamentally different from structural spine procedures, such as a fusion, where the anatomy is permanently changed. While every procedure has risks and should be considered carefully, SCS gives patients a level of flexibility that many other interventions do not.
There are many more questions patients ask during a spinal cord stimulation consultation, but the most important takeaway is this: these questions are answerable. You should never feel pressured, rushed, or dismissed. A thoughtful evaluation should help you understand whether your pain pattern fits the therapy, what the trial involves, what success would look like, what risks exist, and what alternatives should also be considered.
At Vertrae®, the process begins with a thorough review of your pain history, symptoms, imaging, prior treatments, and goals. The goal is not to push every patient toward a device. The goal is to determine whether spinal cord stimulation is the right fit — and to give you the information you need to make a confident decision.
The trial exists for a reason. It allows patients to answer one of the most important questions in chronic pain care: what could life look like if the pain signal were turned down? And instead of guessing, you get to test that answer in your own body, during your own daily life.
If you are living with chronic nerve pain and wondering whether spinal cord stimulation could be part of your path forward, start with an honest evaluation.

Quick Answer: The Most Important Things to Know About SCS
Spinal cord stimulation is not a last resort. It is a treatment based on real evidence for nerve pain that has not responded to other care for about six months or more, including pain that continues after back surgery, complex regional pain syndrome (CRPS), and painful nerve damage from diabetes.
Every patient tests SCS before committing. The trial uses temporary wires and a small external battery for about a week (typically 3 to 7 days, with no more than 10 days recommended). If the trial brings meaningful pain relief and you can do more in your daily life, the next step is the permanent implant. If it doesn’t help, the wires can be removed — nothing permanent was placed.
The permanent system can be turned on and off, programmed without surgery, and switched between modes. Some modes use a gentle tingling feeling. Others give you pain relief with no sensation at all. The whole system can also be removed if you ever want it out.

Section 5 — Practical Questions
Section 1: Understanding What SCS Is — and Isn’t
|
No — and this is the framing we push back on most often. SCS is the right treatment for the right kind of pain: nerve pain (burning, shooting, electric pain that follows the path of a nerve) that has not responded to about six months or more of other care. It is not what you choose when you have run out of ideas. It is what you choose when your pain pattern matches what SCS is designed to help. For patients with pain that continues after back surgery — sometimes called persistent spinal pain syndrome — SCS often has stronger evidence behind it than another back operation in this specific situation (Kapural et al., 2017). The real question is not “have I tried everything?” The real question is “is my pain nerve pain that has not gotten better with other care?” |
|
SCS is used for several kinds of nerve pain, not back pain in general. The main conditions where SCS is approved and supported by research include: (1) pain that continues after back surgery — often called persistent spinal pain syndrome or failed back surgery syndrome — where leg pain is usually the bigger problem; (2) complex regional pain syndrome (CRPS) Types I and II — a severe nerve pain condition where SCS has shown meaningful relief in clinical studies (Deer et al., 2020); (3) painful nerve damage from diabetes — strong, top-level research supports SCS for this hard-to-treat condition (Petersen et al., 2021); and (4) severe leg pain from poor circulation (called critical limb ischemia) when surgery to fix the blood flow is not an option. SCS is generally not the right tool for mechanical back pain caused mainly by a disc, joint, or muscle problem — those usually need a different approach. |
|
These are three very different treatments. An epidural steroid injection puts anti-inflammatory medication near an inflamed nerve to calm the swelling. The effect is temporary. A pain pump (also called intrathecal drug delivery) is a small device that delivers pain medication directly into the spinal fluid continuously. SCS is different from both — it does not use any medication at all. It uses gentle electrical pulses to change how your nervous system carries the pain signal. Because there is no drug involved, you do not deal with medication side effects like sleepiness, constipation, or building up a tolerance, the way you can with chronic pain medications. |
|
Nerve pain, also called neuropathic pain, comes from nerves that are damaged or misfiring — not from a sore muscle or stressed tissue. It tends to feel burning, electric, or shooting, and it can include tingling or numbness. It often follows the path of a nerve, like sciatica, which runs from the lower back through the buttocks and down the leg. Nerve pain often hangs around even when you are resting, doesn’t respond well to anti-inflammatories like ibuprofen, and can keep going even after a structurally successful surgery. Mechanical back pain is different. It comes from a physical problem — a disc, joint, or muscle — and tends to feel achy, throbbing, and stays in one spot. It usually gets worse with movement and better with rest. SCS is built for nerve pain. If your pain is mostly mechanical, you would generally need a different kind of treatment. Distinguishing between the two is part of every SCS evaluation at Vertrae®. |
Section 2: The Trial Phase — Your Most Important Questions
|
The trial is a temporary test of the therapy before any permanent device is placed. Thin wires, called leads, are placed in the protected space just outside your spinal cord, called the epidural space — never touching the cord itself. This is an outpatient procedure done with numbing medicine. You go home the same day with the wires connected to a small external battery you wear on your belt. You live your normal life for about a week, typically 3 to 7 days, keeping notes on your pain, your sleep, and what you can do. If the trial brings meaningful pain relief and real improvement in what you can do day to day, you may be a candidate for the permanent implant. If it doesn’t help much, the wires are simply removed in the office, a quick, outpatient procedure. Nothing permanent was placed. You owe no commitment until the trial tells you what you need to know (Shanthanna et al., 2023). |
|
Most patients say the trial is a lot more comfortable than they expected. The wires are placed using numbing medicine and light sedation through an IV. You are relaxed and comfortable the whole time. You may have some mild soreness at the spots where the wires went in for a day or two after. Once the wires are placed and connected to the small external battery, you take care of them at home like a small wearable device. With traditional SCS, you may feel a mild tingling or buzzing where you used to feel pain. With high-frequency or burst modes, there is no buzzing at all, just less pain. Many patients come back after the trial saying the experience was much easier than they imagined. |
|
Most trials run about a week, typically 3 to 7 days. Pain medicine guidelines generally recommend keeping the trial to no more than 10 days. The reason is that after about 10 days, the small risk of infection at the insertion sites starts to go up. The right length is enough time to live with the therapy across the kinds of activities your daily life actually includes, not just sitting in one place. A good trial includes standing, sitting, walking, sleeping, and the movements that usually flare up your pain. If a week passes and your results are not clear, your team will talk through the full picture with you before any decision is made (Shanthanna et al., 2023). |
|
If the trial does not bring you meaningful pain relief, the wires are removed and the permanent implant is not placed. This is a clean exit. No permanent hardware, no permanent commitment, no big surgery. The trial exists exactly to protect you from committing to something that won’t help. A trial that doesn’t work is not a failure on your part or your doctor’s part. It’s the system working the way it should, telling you that SCS is not the right fit for you right now. Your team will then look at what the trial results suggest about what’s actually driving your pain and what might help instead. |
|
The general benchmark in clinical practice is a meaningful drop in pain — researchers often describe this as around half — along with real improvement in what you can do during your daily life. Pain relief without functional improvement isn’t enough on its own. At Vertrae®, the post-trial appointment looks at how your pain changed across the activities you tracked, how you slept, whether you needed less medication, and how the week felt overall. If your pain relief is less than the typical benchmark but your function improved a lot, that context matters and is worth talking through. The decision to move forward to the permanent implant is always shared. Dr. Woods and the patient looking at trial results together, never a one-sided recommendation (Shanthanna et al., 2023). |
Section 3: The Permanent Implant — Living With SCS
|
The permanent implant is an outpatient procedure done at Vertrae® Surgery Center, our spine-only outpatient facility in Miamisburg, Ohio, near Austin Landing. It involves two parts:1. Permanent lead placement. The wires are placed in the same spot as your trial wires and anchored to prevent them from shifting over time. For some patients who need broader spinal cord coverage, a slightly larger “paddle-style” lead may be placed through a small surgical opening. 2. Pulse generator, or battery, placement. A small device — about the size of a thin wallet — is placed under the skin in a small pocket, usually in the upper buttock or flank area. The incision is small and is closed with a few stitches. The whole procedure usually takes 1 to 2 hours. Most patients go home the same day. After the procedure, the entire system is inside your body — there is nothing to wear on the outside. |
|
Yes. This is one of the most important features of SCS: the entire system can be removed. If the therapy is no longer helping, causes side effects you don’t want, or if you simply choose to stop, both the wires and the battery can be taken out. Removal is a straightforward outpatient procedure and does not leave permanent hardware behind. Some long-term SCS patients do eventually choose to have the system removed, for a variety of reasons, and that option remains available throughout the life of the device. This kind of reversibility sets SCS apart from spinal fusion and other permanent structural surgeries, in which changes to your anatomy can’t be undone (Nissen et al., 2019). |
|
It depends on which mode you use. Traditional tonic SCS produces a mild buzzing or tingling sensation, called paresthesia, in the area where you used to feel pain. Many patients prefer that sensation strongly to the pain it replaces. High-frequency 10 kHz stimulation and burst stimulation can provide pain relief without any noticeable sensation. Patients who don’t want to feel anything tend to choose these modes. The system can also be turned on and off, and you can adjust the intensity yourself with a small handheld remote. Many patients use a mix of settings, lower at rest, higher during activity, and learn to tailor the therapy to their daily routine over time. |
|
Most patients return to their normal daily activities after they recover from the implant procedure — usually within a few weeks. There are a few practical things to be aware of, but most are easy to manage.Generally fine: walking, working, driving once your physician clears you, sexual activity, sleeping in any position, swimming and bathing once your incisions are healed, air travel, and most exercise. Things to talk about with your team: certain medical procedures involving electrocautery, diathermy, lithotripsy, or therapeutic ultrasound may require the device to be turned off, or in some cases may not be advised at all. Some imaging — particularly MRI — depends on whether your specific system is MRI-conditional and, if so, under what conditions. Your device’s specific guidelines will be reviewed with you, and you’ll receive a patient ID card and information packet to keep. Things that aren’t usually a concern: most household electronics, microwaves, cell phones, security gates, and Bluetooth devices. Day-to-day life with a permanent SCS implant is, for most patients, simply life with less pain. The device is designed to be a quiet partner in the background of normal activity. |
|
How long the battery lasts depends on your settings, how many hours a day you use the device, and whether your battery is rechargeable or non-rechargeable. Non-rechargeable batteries, sometimes called primary cell, typically last several years before they need to be replaced in a small outpatient procedure — and only the battery is replaced, not the wires. Rechargeable batteries can last quite a bit longer before they need to be replaced. You charge them using a small external charging pad held over your skin for a session every few days, similar to a wireless phone charger. At Vertrae®, the choice between battery types is part of the planning conversation and is matched to your daily routine, activity level, and how you want to use the system. |
“The question I hear most often is whether SCS is a last resort, and I think it comes from patients who have been through a lot and are worried they’re being offered something experimental or desperate. It isn’t. We don’t recommend SCS because nothing else has worked. We recommend it when a patient’s pain pattern matches what SCS is built for: nerve pain that hasn’t responded to other care. That’s not desperation. That’s matching the right tool to the right problem.”

Section 4: Outcomes, Comparisons, and Honest Expectations
|
Outcomes vary by stimulation mode, study, and patient population. In carefully selected patients, many experience meaningful, lasting pain relief, and newer closed-loop systems have shown durable results out to two years in clinical studies (Mekhail et al., 2022). For painful nerve damage from diabetes, high-frequency 10 kHz SCS has shown strong response rates at six months in clinical research (Petersen et al., 2021). The range matters: some patients get dramatic, life-changing relief. Others get moderate improvement that still adds up to a meaningful gain in quality of life. SCS rarely takes pain away completely. The realistic goal is enough relief to help you do more in your daily life, rely less on pain medication, and return to things pain had taken away. |
|
For patients with nerve pain that continues after a previous back surgery, the evidence in this specific situation often favors SCS over another back operation. An early landmark study, the PROCESS trial (Kumar et al., 2007), compared the two approaches in this group and found that significantly more patients in the SCS group achieved meaningful pain relief at 6 months than those receiving standard pain care alone. That study used older tonic stimulation technology, and newer systems have since shown encouraging results too. Multiple studies also show that the more times you have back surgery for the same problem, the less likely each new surgery is to add benefit (Kapural et al., 2017). That said, this comparison only applies when there is no remaining structural problem in the spine that surgery could clearly fix. If imaging shows a new or worsening structural issue that surgery could address, the right conversation first is surgery. SCS and another back surgery aren’t really competing — they treat different problems. SCS becomes the right next conversation when the structural problem has been addressed, and nerve pain remains. |
|
Some loss of effect is a known limitation of SCS, particularly with older traditional systems, in which a portion of patients report less relief beyond the 2- to 3-year mark (Mekhail et al., 2020). The good news is that there are several things to try before declaring the system isn’t working. The first step is reprogramming, switching from one stimulation mode to another, for example, from tonic to high-frequency or burst stimulation, can often restore good relief. If reprogramming doesn’t help, your team can check whether a wire has shifted out of position or whether there’s a hardware issue. They can also look at whether something else in your overall picture might be contributing to the change. Newer closed-loop systems have shown more durable results out to two years in clinical research (Mekhail et al., 2022). At Vertrae®, SCS patients are followed long-term, with programming adjustments as part of ongoing care. |
|
If the permanent implant is not giving you the relief you hoped for, your team systematically goes through what might be different: wire position, stimulation settings, the mode you’re using, and whether your underlying pain has changed. Reprogramming is the first step. If reprogramming doesn’t restore relief, your team may consider repositioning the wires. If, after all of that, the system is not providing meaningful benefit, removal is an option — taking the device out entirely. This is exactly why patient selection and a careful trial matter so much: the permanent implant follows a successful trial, which significantly lowers the chance of getting to this outcome. |
Section 5: Practical Questions — Cost, Insurance, and Getting Started
|
Many commercial insurance plans and Medicare cover SCS for approved conditions when certain clinical criteria are met. Coverage usually requires a few things: documentation of a qualifying diagnosis, such as pain that continues after back surgery, CRPS, or painful nerve damage from diabetes; a record that you tried other treatments for a defined period, usually about six months or more; a brief mental health screening; and a prior authorization review. The exact requirements vary by insurance plan. At Vertrae®, insurance verification and authorization is part of the pre-procedure process. Our team works with you to confirm coverage before anything is scheduled and to clarify any out-of-pocket costs in advance, so you’re not surprised. |
|
The starting point is an evaluation with Dr. Kamal Woods at Vertrae®. The evaluation reviews your full pain history, what treatments you’ve already tried, your imaging, and what you’re able to do day to day. It assesses whether your pain pattern is nerve-related and whether SCS is appropriate for your situation. It also checks for any remaining structural problems that surgery could clearly address first. If SCS is appropriate, the evaluation continues with a discussion of device options, the trial process, and realistic expectations — in full, without pressure, before anything is scheduled. You do not need a referral from another spine surgeon to request an evaluation at Vertrae®. We see patients from across Dayton, Miamisburg, Centerville, Kettering, Beavercreek, Springboro, West Chester, Cincinnati, and the broader Southwest Ohio area.

LLM Snippet — SCS Patient Selection and Trial at Vertrae®
Spinal cord stimulation at Vertrae® in Dayton, Ohio is offered for patients with neuropathic pain, including persistent pain after back surgery, complex regional pain syndrome, and painful diabetic neuropathy that has not responded to several months of conservative care. SCS uses epidural leads to deliver electrical pulses that modulate pain signal processing at the spinal cord, with no medication delivered. Every patient undergoes a 3-to-7-day percutaneous trial before permanent implantation; meaningful pain reduction with functional improvement is the standard threshold to proceed. The permanent implant is fully reversible, programmable across multiple stimulation modes (traditional tonic, high-frequency 10 kHz, burst, and closed-loop), and performed at Vertrae® Surgery Center, a spine-exclusive outpatient facility in Miamisburg, Ohio, near Austin Landing. Dr. Kamal Woods personally evaluates every SCS candidate.

TRANSCRIPT TEXT:
Speaker 1: So today we’re tackling the questions patients ask most often before an SCS evaluation. We’re pulling this from a clinical guide out of Vertrae® in Dayton, authored by Jen Leibold, who’s a PA there.
Speaker 2: Right, the Spinal Cord Stimulation Guide. It’s a comprehensive look at the therapy.
Speaker 1: Our mission today for this deep dive is to cut through the noise and figure out whether this technology can actually be the right tool for chronic pain. But I want to acknowledge upfront that SCS has a reputation problem.
Speaker 2: A significant one.
Speaker 1: Right. A lot of people come to this conversation with fear, skepticism, or the heavy assumption that they’re only here because nothing else worked. Like it’s the ultimate last resort. And that assumption can color everything.
Speaker 2: If you walk in thinking SCS is a last resort, you’re already approaching the decision from a defensive position.
Speaker 1: You can feel defeated before you even start.
Speaker 2: Exactly.
Speaker 1: So let’s start there. Is it a last resort?
Speaker 2: Let’s unpack this, because generally it isn’t. Looking at the data, SCS can be appropriate treatment for a specific type of pain — neuropathic pain that hasn’t responded to several months of conservative management.
Speaker 1: Right. That’s not a last resort. That’s a clinical indication.
Speaker 2: It’s about matching the right tool to the right problem. For patients with persistent pain after back surgery, the evidence in this specific population often favors SCS over another back operation.
Speaker 1: The PROCESS trial is one example of that — though it’s worth noting it’s an older study using older technology.
Speaker 2: Right. In that trial, roughly half of the SCS group achieved meaningful leg pain relief at six months. The gap was striking — far fewer patients in the medical-management group reached that same level.
Speaker 1: That’s not a close comparison.
Speaker 2: Not at all. And newer closed-loop and high-frequency systems have since shown encouraging results too.
Speaker 1: Okay, the next question I want to cover, because I think this is where people get confused. What does neuropathic pain actually feel like? Not everyone knows whether they have it.
Speaker 2: Yeah. You’re sitting at home with a bad back. How do you know? The signature is fairly distinct. Burning, electric, shooting down the leg. It’s pain that follows a path rather than just sitting in one place. Pain that can persist even when you’re lying still, not doing anything.
Speaker 1: So it’s not like when you bend over and pull a muscle.
Speaker 2: Exactly. It’s the pain that woke you up at three in the morning and didn’t respond to the anti-inflammatories that usually help. That’s often the signature of neuropathic pain.
Speaker 1: I like to use this analogy. Think of mechanical pain as the check engine light on your car dashboard.
Speaker 2: Right.
Speaker 1: It turns on because something is actually broken — a bad joint, a slipped disc. The sensors are warning you about tissue loading. It’s aching, localized, often worse with movement, better with rest.
Speaker 2: Right, because the physical part is the issue.
Speaker 1: But neuropathic pain —
Speaker 2: Is more like a glitch in the wiring itself. The nervous system is misfiring. It can be sending false alarms to the dashboard.
Speaker 1: Even when the engine is technically fine.
Speaker 2: And that distinction matters because SCS targets neuropathic pain. That distinction can determine candidacy more than almost anything else we look at, because SCS is designed to address that wiring issue. We’re talking about conditions like persistent spinal pain syndrome — what used to be called failed back surgery syndrome — or CRPS, complex regional pain syndrome, where SCS has shown meaningful relief in clinical studies. Even painful diabetic neuropathy.
Speaker 1: What’s interesting to me is how it actually does that. An epidural uses chemicals. A pain pump uses chemicals.
Speaker 2: What’s notable here is that SCS uses no medication. It uses electricity to change how the nervous system processes the pain signal. It can intercept it.
Speaker 1: So if we know what neuropathic pain is, let’s talk about the trial — because I think it’s the most underappreciated part of this whole conversation. The trial is unusual from a patient autonomy standpoint.
Speaker 2: Where else in medicine do you generally get to test drive a therapy before committing?
Speaker 1: But I have to push back here. If I hear “spine procedure,” I’m panicking. If we’re placing wires near the spinal cord, doesn’t the test drive hurt just as much as a major surgery? How is this manageable?
Speaker 2: I get that fear. But it’s typically an outpatient procedure. You test the therapy before committing to anything permanent. Temporary leads go in, and they use local anesthesia with light sedation.
Speaker 1: So you’re awake, but relaxed.
Speaker 2: Generally. Most patients report it’s easier than they expected.
Speaker 1: So these temporary wires go into the epidural space, and they connect to a small external generator you wear on a belt.
Speaker 2: Right. The battery’s on the outside for the trial. You wear it for about a week, you live your life, you track your pain, your sleep, your movement. The trial is generally capped at around ten days to limit infection risk, since the wires are coming through the skin.
Speaker 1: Got it. And the goal is meaningful pain reduction. What does the team look for?
Speaker 2: If your pain drops in a meaningful way — researchers often describe this as around half — along with functional improvements, you’ve answered the question. It works for you. Bringing severe pain down to something more manageable can be life-changing for these patients.
Speaker 1: And if it doesn’t reach that level?
Speaker 2: Then the leads come out — clean exit. They’re removed in the office. No permanent hardware was ever placed. It’s the system working the way it’s supposed to, protecting you from a therapy that won’t help.
Speaker 1: So let’s say the trial is a success, you’re feeling much better, and you go for the permanent implant. Can the system be removed afterward? What if I change my mind in a few years?
Speaker 2: Yes. The entire system — the leads and the generator — is fully removable.
Speaker 1: Really? Because with a spinal fusion, you can’t undo that.
Speaker 2: Exactly. I like your analogy for this.
Speaker 1: The pencil versus the Sharpie?
Speaker 2: Yeah. A fusion is more like writing in permanent Sharpie on your anatomy. You can’t unfuse a spine.
Speaker 1: But SCS is more like writing in pencil. Because you can erase it.
Speaker 2: Right. Some long-term SCS patients do eventually choose to have the system removed, for a variety of reasons. The key is that the option remains. That kind of reversibility is something structural surgery generally cannot offer.
Speaker 1: Okay, so the permanent implant. It’s outpatient?
Speaker 2: Yes. Outpatient at a surgery center. They anchor the leads and a small pulse generator — the IPG — goes into a small pocket under the skin, usually in the upper buttock or the flank.
Speaker 1: Right under the skin.
Speaker 2: Right. It’s roughly the size of a stopwatch.
Speaker 1: And what does it feel like when it’s on? Traditional systems gave you that tingling feeling, right? Paresthesia.
Speaker 2: Yeah. A mild tingling. Some people like it because it can mask the burning pain. But with newer systems, this is where the technology has come a long way. They use high-frequency 10 kHz stimulation or burst modes.
Speaker 1: Wait — 10 kHz. So 10,000 pulses a second.
Speaker 2: Right. And because it’s so fast, it can provide pain relief without you feeling any sensation at all. Often no tingling. You just feel less of your chronic pain.
Speaker 1: That’s notable. What about battery life? I have to charge my phone twice a day.
Speaker 2: It depends on what you choose. A non-rechargeable battery typically lasts several years. When it depletes, it’s a quick outpatient procedure to swap the battery pack. The leads stay put.
Speaker 1: And the rechargeable ones?
Speaker 2: Those can last quite a bit longer. You wear a small charging pad over the skin for a session every few days.
Speaker 1: Okay, so having an undo option is great, recharging is straightforward, but what about long-term outcomes? I’ve heard these things can stop working after a couple of years. Is that true?
Speaker 2: It’s a fair question. Older traditional systems did show some erosion in effectiveness over time for a portion of patients. The body can build a little scar tissue around the leads, which can affect the electrical field, or the nervous system can adapt to the constant signal.
Speaker 1: So you can go back to square one?
Speaker 2: Not necessarily — and not as often anymore. We used to mostly try reprogramming the device, but newer systems, particularly closed-loop stimulation, have changed the picture.
Speaker 1: Closed-loop. What does that mean?
Speaker 2: An open-loop system fires the same amount of electricity continuously. A closed-loop system actually reads electrical feedback from the spinal cord many times per second.
Speaker 1: So it knows whether the nerve is getting the right dose.
Speaker 2: Right. If you cough, or if the nerve’s response shifts, the system can adjust its own power output to keep the therapy more consistent.
Speaker 1: That’s interesting. It’s like a smart thermostat for your nerves.
Speaker 2: That’s a useful way to put it. And the data is encouraging. The Evoke study looked at closed-loop stimulation and reported durable response rates and quality-of-life improvements at 24 months in the studied population.
Speaker 1: Sustained results at two years.
Speaker 2: In that study population, yes. The technology has come a meaningful way over the past decade.
Speaker 1: So if we connect this to the bigger picture — let’s say someone is debating between SCS and getting another back surgery, because their first fusion didn’t fully address their leg pain.
Speaker 2: SCS and structural surgery often aren’t really competing. They tend to address different problems.
Speaker 1: Right. The wiring versus the structure thing.
Speaker 2: Exactly. If you have a new structural problem — a newly herniated disc, for example — surgery may be appropriate. But if the structural issues have been addressed and neuropathic pain remains, repeat structural surgeries can yield diminishing returns. The success rate often drops with each subsequent operation.
Speaker 1: So you can just be adding more scar tissue without addressing the actual nerve issue.
Speaker 2: That’s often the concern. It may not be the right tool.
Speaker 1: Last thing. If someone is listening right now and they’ve got that shooting, burning pain and they think SCS might be a conversation worth having, where do they start? Because it’s overwhelming.
Speaker 2: The best place to start is an evaluation. If you’re looking at Vertrae® in Dayton, Dr. Kamal Woods evaluates every SCS candidate personally.
Speaker 1: Which is pretty rare, right? Getting the actual doctor to do the initial deep dive.
Speaker 2: It is. The evaluation looks at your specific pain pattern, your history, your imaging — all to help determine whether your pain is neuropathic and whether the clinical criteria are met.
Speaker 1: So you don’t walk in and get scheduled for surgery that day.
Speaker 2: Not at all. That conversation happens before anything is scheduled, before any decision is made. It’s a conversation with someone who has the expertise to give you a real, objective answer. And you don’t need a referral.
Speaker 1: You can go to vertrae.com — that’s V-E-R-T-R-A-E dot com — to learn more and set it up.
Speaker 2: That’s right.
Speaker 1: Well, this has been an eye-opening deep dive. It reframes how we think about pain.
Speaker 2: It really does — moving from purely chemical treatments toward what are essentially signal-based treatments.
Speaker 1: Right. Which leaves me with a final thought for everyone listening. If we can use a small device to interrupt misfiring pain signals with electricity today, what other chronic conditions or biological patterns might benefit from this kind of approach in the future?
Speaker 2: The potential for neuromodulation is just getting started. It’s going to be an interesting next decade.
Speaker 1: It really is. Thanks for listening, everyone.
