An SCS system consists of a small device, similar to a pacemaker, implanted under the skin. Thin wires (leads) are placed near the spinal cord to deliver mild electrical pulses. These pulses block or alter pain signals traveling through the spinal nerves, replacing them with a tingling sensation or no sensation at all.

The process typically begins with a trial procedure to ensure SCS provides significant pain relief. If the trial is successful, a permanent stimulator can be implanted.

SCS is not used to treat the underlying condition but to manage chronic pain caused by:

• Failed Back Surgery Syndrome (Post-Laminectomy Syndrome) – persistent pain after one or more spinal surgeries

• Complex Regional Pain Syndrome (CRPS) – severe, ongoing nerve pain in the arms or legs

• Peripheral Neuropathy – nerve damage causing chronic tingling, numbness, or burning pain

• Spinal Stenosis or Herniated Discs – when other treatments have failed to relieve nerve pain

• Chronic Radiculopathy (sciatica or arm pain) – nerve pain radiating from the spine into the limbs

• A temporary trial stimulator is placed first to test effectiveness.

• If successful, a permanent stimulator is implanted in a minimally invasive outpatient procedure.

• The device is programmable and can be adjusted externally to optimize pain relief.

• Most patients go home the same day and return to normal activity within days to weeks.

Patients may be candidates for SCS if they experience:

• Chronic pain lasting more than six months

• Pain not relieved by medications, injections, or physical therapy

• Pain interfering with daily activities and sleep

• Radiating leg or arm pain (neuropathic pain)

• A history of back surgery without significant pain improvement
