Spinal Cord Stimulator Trial

A Spinal Cord Stimulator (SCS) Trial is a temporary procedure that allows patients to experience spinal cord stimulation therapy before a permanent system is implanted. This trial phase helps determine how effectively the device reduces pain and improves daily function. By sending mild electrical impulses to interrupt pain signals traveling to the brain, the trial system can provide meaningful short-term relief and confirm whether long-term implantation is the right option.

Quick facts

  • Setting: Outpatient, image-guided
  • Time: ~45–60 minutes
  • Anesthesia: Local with light sedation
  • Recovery: Same-day discharge; avoid strenuous activity for several days
  • Trial duration: Typically 5–7 days

Who it helps

  • Chronic back or leg pain after spine surgery (post-laminectomy syndrome)
  • Nerve pain (neuropathic pain) not relieved by injections or medication
  • Complex Regional Pain Syndrome (CRPS)
  • Peripheral neuropathy or radiculopathy
  • Patients considering long-term spinal cord stimulation therapy

How it works

The SCS trial uses temporary leads placed near the spinal cord that connect to an external stimulator worn on a belt or shoulder strap. The device sends small electrical impulses that interfere with pain signal transmission to the brain. This reduces the perception of pain, replacing it with a mild tingling or comfortable sensation. The trial allows both you and your provider to assess how much pain relief and functional improvement spinal cord stimulation offers before proceeding with a permanent implant.

What to expect

  • Before: Your provider will review your medical history and imaging to confirm you’re a candidate. You’ll receive light sedation for comfort during the procedure.
  • During: The provider inserts thin, flexible leads through a needle into the epidural space near the spinal cord under fluoroscopic (X-ray) guidance. These leads are connected to an external stimulator that delivers controlled electrical impulses.
  • After: You’ll go home the same day with detailed instructions on how to use the external stimulator. Over the next week, you’ll track your pain relief, activity level, and comfort. If the trial significantly reduces your pain, your provider will recommend proceeding with a permanent implant.

Benefits & risks

Benefits:

  • Temporary, reversible procedure
  • Provides insight into how well spinal cord stimulation may work for you
  • Can result in significant short-term pain relief
  • Helps avoid unnecessary surgery if therapy isn’t effective

Risks:

  • Temporary soreness or bruising at the insertion site
  • Infection or bleeding (rare)
  • Lead displacement or device malfunction (rare and reversible)
  • Temporary increase in pain before improvement

Is it right for me? (Checklist)

  • ✅ Chronic back, leg, or nerve pain unresponsive to conservative care
  • ✅ Open to evaluating advanced, minimally invasive pain therapy
  • ✅ No contraindications to device placement
  • ✅ Willing to track results and report progress during the trial

FAQs

  • How long is the trial? The trial typically lasts about one week, after which the temporary leads are removed in the office.
  • What results indicate success? A reduction of at least 50% in pain and improved ability to perform daily activities are considered positive outcomes.
  • Is the procedure painful? Mild discomfort may occur, but local anesthesia and sedation minimize pain.
  • What happens if the trial doesn’t work? The leads are easily removed, and your provider will discuss alternative treatments.
  • Is it covered by insurance? Most insurance plans, including Medicare, cover SCS trials when medically indicated.
