Spinal Cord Stimulation (SCS)

Spinal cord stimulation (SCS) is an advanced, minimally invasive treatment that uses mild electrical impulses to modify pain signals before they reach the brain. A small device is implanted under the skin, with thin wires placed near the spinal cord. These wires deliver controlled electrical signals that help reduce how the body perceives pain. 👉 Think of it like a “volume control” for pain—reducing the intensity without major surgery.

What Conditions Does This Treatment Help?

Spinal cord stimulation is commonly used to treat:

How Does Spinal Cord Stimulation Work?

Pain signals travel from nerves → spinal cord → brain.
  • Electrodes are placed near the spinal cord
  • A small generator sends low-level electrical impulses
  • These signals interfere with or “mask” pain signals
  • The brain perceives less pain
Some patients feel a mild tingling sensation, while newer systems may provide relief without any noticeable sensation.

What to Expect During the Procedure

Before the Procedure
  • Evaluation of pain history and prior treatments
  • Psychological and medical screening (if needed)
During the Procedure
  • Performed under local anesthesia or sedation
  • Leads placed in the epidural space using imaging
  • Generator implanted under the skin
  • Procedure typically takes 1–2 hours
After the Procedure
  • Same-day or short-stay discharge
  • Activity restrictions for a few weeks
  • Device programming customized to your pain

Benefits of Spinal Cord Stimulation

✔ Minimally invasive alternative to major spine surgery
✔ Can significantly reduce chronic pain
✔ Decreases reliance on pain medications
✔ Improves sleep and quality of life
✔ Adjustable and reversible treatment

👉 Many patients experience meaningful long-term pain relief and improved daily function.

Who Is a Good Candidate?

You may be a candidate if you:
  • Have chronic pain lasting 6+ months
  • Have not improved with medications, therapy, or injections
  • Have nerve-related or post-surgical pain
  • Want to avoid or are not a candidate for major surgery
👉 Best results occur in patients with clearly diagnosed nerve-related pain.

Risks & Side Effects

Spinal cord stimulation is generally safe, but risks may include:
  • Infection or bleeding
  • Lead movement (device may need adjustment)
  • Device malfunction
  • Temporary discomfort at implant site
  • Rare nerve injury
Most complications are uncommon and manageable with proper care.

When Is This Treatment Recommended?

Spinal cord stimulation is typically recommended when:
  • Conservative treatments have failed
  • Pain is chronic and nerve-related
  • Surgery is not effective or not recommended
  • Patients want a reversible, non-destructive treatment
👉 It is positioned as an advanced therapy before or instead of major surgery

Recovery & Results

  • Initial recovery: 2–4 weeks
  • Gradual return to normal activities
  • Pain relief may be immediate or improve over time
  • Device settings can be adjusted as needed
👉 Many patients experience long-term improvement in pain and quality of life.

FAQs

Most patients experience minimal discomfort due to anesthesia and sedation.

Some patients feel a mild tingling sensation, while newer systems may not be felt.
Battery life varies, but many devices last several years.

Yes, the system is reversible if needed.

FAQs

The system includes a small device implanted under the skin, thin wires (leads) placed near the spinal cord, and a controller to adjust stimulation.

Yes, a weeklong trial simulation is performed to test how much pain relief the patient experiences before scheduling the long-term implant.

SCS can treat post-laminectomy syndrome, Complex Regional Pain Syndrome (CRPS), phantom limb syndrome, end-stage peripheral vascular disease, post-herpetic neuralgia, incomplete spinal cord injury, plexopathy, and lumbosacral arachnoiditis.

If the patient experiences significant pain relief, they can choose to proceed with a long-lasting spinal cord stimulator implant.

At 6 months, 82% of patients had significant pain relief (≥50% reduction), 72% improved function, and 42% reduced their medication usage.
