Procedure Description
A Peripheral Nerve Stimulator (PNS) is an advanced, minimally invasive treatment that uses mild electrical impulses to modulate pain signals from a targeted peripheral nerve. The system consists of a tiny wire-like electrode placed near the affected nerve and a small pulse generator that sends controlled stimulation to block or reduce pain perception.
The process involves two phases:
A trial phase to determine effectiveness.
A permanent implant if the trial provides significant pain relief.
PNS is often used when pain is localized and has not responded to conservative treatments such as medications, physical therapy, or injections.
What It Treats
PNS is commonly used to manage:
Post-surgical nerve pain (e.g., knee, shoulder, or hernia surgery)
Occipital neuralgia
Peripheral neuropathy
Complex Regional Pain Syndrome (CRPS)
Chronic pain in the arms, legs, or trunk
Amputation-related (post-limb loss) pain or phantom limb pain
Post-traumatic nerve injuries
PNS is ideal for focal nerve-related pain that is well-defined and does not involve the spine.
How It Is Performed
Phase 1: Trial Procedure
You will be positioned comfortably based on the nerve being targeted.
The area is cleansed and numbed with local anesthetic.
Using ultrasound or fluoroscopic guidance, a thin trial lead (wire) is inserted next to the affected peripheral nerve.
The lead is connected to an external stimulator worn on a belt or strap.
The stimulator is programmed, and you’ll test the system for 3–7 days, adjusting settings as needed with a handheld remote.
If the trial provides ≥50% pain relief and improved function, you may proceed to permanent implantation.
Phase 2: Permanent Implant
Performed in an outpatient surgical suite under local anesthesia with sedation or general anesthesia.
A permanent lead is placed in the same location, and a small pulse generator is implanted just under the skin (typically in the upper arm, buttock, or flank).
The device is fully internal and wirelessly controlled with an external remote.
The incision is closed, and the device is activated and programmed.
The full procedure typically takes 60–90 minutes.
Pre-Procedure Instructions
Do not eat or drink for at least 6–8 hours if sedation is planned.
Discuss your medications with your provider. Blood thinners may need to be paused.
Inform your provider if you:
Are pregnant or breastfeeding
Have a pacemaker or implanted defibrillator
Have an active infection or bleeding disorder
Have metal allergies or are undergoing MRI testing
Arrange for a driver to take you home after each procedure.
Wear loose, comfortable clothing, especially near the area to be treated.
What to Expect After the Procedure
After the Trial:
You may experience immediate pain relief.
Keep the trial site dry and clean, and follow specific instructions on activity restrictions.
Your provider will assess pain relief and functional improvement to determine whether to proceed with permanent implantation.
After the Permanent Implant:
Mild soreness at the incision or lead site is common and resolves within days.
You’ll receive instructions on using the remote control and adjusting stimulation.
Most patients return to normal activities within 1–2 weeks.
The stimulator may be turned on/off or adjusted at home.
Call your provider if you experience:
Fever, chills, or signs of infection
Persistent numbness or weakness
Severe pain, swelling, or drainage from the surgical site
