Spinal cord stimulation (SCS) is a targeted, minimally invasive therapy designed to interrupt pain signals traveling from the spine to the brain. A thin lead carrying tiny electrical pulses is positioned near the spinal cord; those pulses alter how pain is perceived, often reducing the intensity of chronic back, leg, or neuropathic pain. Because it acts on the nervous system’s signaling pathways, SCS can provide relief for pain that has not responded to conservative measures such as medications, injections, or physical therapy.
Unlike many systemic treatments, SCS works locally at the spinal level, allowing clinicians to focus therapy on the region producing symptoms. The device itself is programmable and adjustable, so stimulation can be tailored to a patient’s changing needs. For many people, this can mean improved daily function, fewer interruptions to sleep, and greater ability to participate in rehabilitation activities that further enhance recovery.
Because the procedure is reversible and adjustable, it is considered a flexible option in the spectrum of chronic pain treatments. The overall goal is to reduce the burden of persistent pain while preserving mobility and quality of life, and to do so with a therapy that can be changed or removed if it does not meet expectations.
Not every patient with chronic pain is a candidate for SCS, and careful evaluation is essential. SCS is typically considered for individuals with neuropathic pain or axial and radicular pain that has been persistent despite non-surgical treatments. Common scenarios include persistent pain after spine surgery, complex regional pain syndrome, refractory neuropathy, and certain types of chronic leg pain. A thorough clinical review—covering medical history, imaging, and prior treatments—helps determine whether SCS is an appropriate next step.
Appropriate candidacy also takes into account a patient’s overall health, expectations, and lifestyle. Because the therapy requires follow-up programming and periodic device management, patients should be willing to engage in ongoing care. During the consultation process, clinicians discuss realistic outcomes, potential risks, and how SCS integrates with other aspects of a patient’s pain-management plan so decisions are made collaboratively and with clear goals in mind.
At the Brain and Spine Institute of New York and New Jersey, Dr. Arien J. Smith and the team evaluate each case individually to ensure SCS is considered only when it aligns with a patient’s clinical picture and treatment objectives. Multidisciplinary input often helps refine the plan and identify the most appropriate candidates.
The path to permanent implantation normally begins with a trial period. During a trial, temporary leads are placed through a needle into the epidural space and connected to an external stimulator. This short-term test—usually lasting several days to a week—allows patients and clinicians to assess whether stimulation provides meaningful symptom relief and functional improvement before committing to a permanent device.
If the trial yields satisfactory results, the next step is a permanent implantation. This involves placing permanent leads (either percutaneous or paddle-style) and implanting the pulse generator in a small pocket beneath the skin, commonly in the lower back or flank. The procedure is typically performed under sedation or general anesthesia and uses minimally invasive techniques to minimize tissue disruption and expedite recovery.
After implantation, the device is programmed to match the patient’s pain distribution and daily activities. Early follow-up visits focus on optimizing stimulation settings and addressing any wound-care or activity questions. Most patients can resume light activities within days and gradually return to normal routines under their clinician’s guidance.
Spinal cord stimulation technology has advanced considerably, giving clinicians a toolbox of waveforms and device types to tailor therapy. Traditional paresthesia-based stimulation produces a tingling sensation that overlaps the painful area, while newer options—such as high-frequency and burst stimulation—can reduce pain without producing noticeable paresthesia. Your care team will discuss the different modes and select an approach based on your symptoms and response to the trial.
Device options also vary in battery life and recharging needs. Rechargeable generators typically offer longer service life and smaller footprints, whereas non-rechargeable units require replacement when the battery is depleted. Lead design is another consideration: percutaneous leads are less invasive to place, while paddle leads may offer greater positional stability in select cases. MRI compatibility and remote programming features are additional factors discussed during device selection.
Successful long-term results depend on close communication between patient and clinician. Routine programming visits, symptom tracking, and coordination with physical therapy or pain specialists help maintain therapeutic benefit and address any changes in pain patterns over time.
When SCS is successful, patients commonly experience meaningful reductions in chronic pain and improvements in daily function. Many can participate more fully in exercise and rehabilitation, and some reduce reliance on oral pain medications. These functional gains are central to the overall aim of SCS: restoring quality of life rather than simply masking symptoms.
As with any implanted device, SCS carries potential risks that patients should understand. Complications can include infection, lead migration or breakage, localized pain at the implant site, or suboptimal pain relief. Most issues are manageable through reprogramming, lead revision, or, in rare cases, device removal. Careful surgical technique, vigilant wound care, and timely follow-up reduce the likelihood of adverse events.
Long-term management typically involves periodic checkups to review device settings, battery status, and clinical progress. A coordinated approach—combining device management with physical conditioning, ergonomic adjustments, and behavioral strategies—often produces the best outcomes. Patients benefit from an individualized plan that adapts as their needs evolve over months and years.
Spinal cord stimulation is a sophisticated option for people living with persistent spinal and neuropathic pain. If you are exploring advanced treatments, the team at the Brain and Spine Institute of New York and New Jersey reviews each case carefully and explains the trial process, device choices, and likely outcomes so you can make an informed decision.

Spinal cord stimulation is a minimally invasive therapy that uses electrical pulses to alter pain signals before they reach the brain. A small generator is implanted under the skin and connected to leads placed near the spinal cord to deliver targeted stimulation. The goal is to reduce chronic back, leg, or neuropathic pain and improve daily function.
Stimulation can be delivered in different waveforms and intensities to match a patient’s symptoms, and most systems allow ongoing programming adjustments. Many patients appreciate that the therapy is reversible and can be tested first with a temporary trial. The procedure is intended as part of a comprehensive pain-management plan rather than a standalone cure.
Good candidates typically have chronic neuropathic or radicular pain that has not responded adequately to conservative measures such as medications, physical therapy, or injections. Patients with failed back surgery syndrome, complex regional pain syndrome, or persistent radicular symptoms are commonly evaluated for this option. The decision to proceed is individualized and based on clinical history, imaging, and prior treatments.
At the Brain and Spine Institute of New York and New Jersey, Dr. Smith and the care team perform a thorough evaluation to determine suitability for a trial and permanent implantation. This evaluation may include a pain specialist, physical examination, review of prior imaging, and discussion of goals and expectations. A successful temporary trial is usually required before moving forward with permanent implantation.
During a trial, temporary leads are placed near the spinal cord using fluoroscopic guidance and connected to an external stimulator that the patient wears for several days. The trial is performed under local anesthesia with mild sedation in an outpatient setting to evaluate pain relief and functional improvement. Patients keep a symptom diary during the trial to document changes in pain, sleep, mobility, and medication use.
Programming adjustments are made during the trial to optimize coverage and comfort, and the care team reviews the results with the patient at the end of the testing period. A trial that provides meaningful pain reduction and improved activity is generally considered a sign that a permanent system may be beneficial. If the trial is successful, scheduling for permanent implantation can be discussed and coordinated with the surgical team.
Spinal cord stimulation can produce significant pain relief for many patients, often improving daily function, sleep, and overall quality of life. The therapy is adjustable, allowing clinicians to tailor stimulation patterns to a patient’s changing needs and activities. Because the approach is minimally invasive and reversible, patients can evaluate benefit during a temporary trial before committing to a permanent implant.
Many patients experience reduced reliance on oral pain medications after successful stimulation, which can simplify overall treatment strategy. The flexibility of modern systems, including paresthesia-free waveforms, helps a wider range of patients find relief. Ongoing follow-up and reprogramming help sustain benefits over time.
As with any surgical procedure, spinal cord stimulation carries risks such as infection, bleeding, and pain at the implant site. Lead migration or breakage, loss of therapeutic effect, and hardware malfunction are among the device-specific complications that can occur. Some patients also experience changes in stimulation sensation or skin irritation from adhesives used to secure external components during a trial.
Long-term management may involve generator replacement or lead revision in the event of battery depletion or device wear. Careful patient selection, sterile technique, and close postoperative follow-up reduce complication rates, and issues are often manageable with timely intervention. Patients should report fever, increasing pain, wound drainage, or sudden loss of stimulation to their care team promptly.
Contemporary spinal cord stimulation systems vary by waveform, lead design, and power source, including paresthesia-based and paresthesia-free (for example, high-frequency or burst) stimulation options. Leads may be percutaneous or paddle-style, and implanted pulse generators can be rechargeable or nonrechargeable depending on the device and patient preference. Device selection is tailored to the patient’s pain distribution, anatomy, lifestyle, and clinical goals.
Advances in programming algorithms and lead technology have expanded the range of problems that can be addressed with stimulation. During the evaluation process, the care team will discuss the relative advantages and trade-offs of different systems to identify the best option. Trialing a system helps determine which technology provides the most meaningful relief before permanent implantation.
Preparation begins with a comprehensive preoperative evaluation that may include medication review, imaging studies, and basic laboratory testing as indicated by medical history. Patients taking anticoagulants or other medications that affect bleeding will receive specific instructions about when to stop and resume those agents. It is also important to disclose any implanted devices, allergies, or prior spine surgeries during the consultation.
On the day of the procedure, patients should arrange for a driver and plan to limit strenuous activity for a short period after the trial or implantation. The care team will provide wound-care instructions, activity restrictions, and guidance on when to resume normal activities. Clear communication about expectations and goals helps the team tailor perioperative planning and postoperative support.
Recovery after implantation is typically faster than after major spine surgery, but patients can expect soreness at the incision site and mild discomfort for several days to weeks. Activity restrictions commonly include avoiding heavy lifting and bending for a few weeks to allow leads to stabilize. Wound checks and initial programming visits are scheduled to monitor healing, confirm lead position, and optimize stimulation settings.
Most patients gradually return to normal activities over several weeks, with individualized guidance from the clinical team regarding work and exercise. Long-term follow-up includes periodic reprogramming and device checks to maintain optimal benefit. If any signs of infection, increasing pain, or loss of stimulation occur, patients should contact their provider promptly for evaluation.
After implantation, patients use a handheld programmer to adjust stimulation within prescribed ranges and to switch programs for different activities. It is important to carry the device identification card and to inform other healthcare providers, including dentists and imaging personnel, about the implanted system. Certain medical procedures and security systems may interact with the device, so coordination with the care team is essential.
Routine follow-up appointments allow for reprogramming, troubleshooting, and assessment of battery status in rechargeable or nonrechargeable generators. Patients should contact their clinic if they experience sudden changes in pain, new neurologic symptoms, wound problems, or device malfunction. The care team will provide guidance on travel, exercise, and long-term device care based on the specific system implanted.
To determine whether spinal cord stimulation is appropriate, start with an evaluation that includes a detailed history, physical examination, and review of prior imaging and treatments. Dr. Smith and the interdisciplinary team discuss goals, review risks and benefits, and recommend next steps such as a diagnostic block, conservative measures, or a stimulation trial when indicated. Shared decision making helps patients weigh expectations and select the most suitable treatment strategy.
If a trial is recommended, the team will explain the process, expected outcomes, and follow-up plan before scheduling. The practice supports ongoing care with programming visits, wound checks, and coordination with affiliated hospitals for any procedures. Patients in East Brunswick and surrounding areas can request a consultation to explore whether spinal cord stimulation fits their overall care plan.
