Neuromodulation

Peripheral Nerve Stimulation (PNS)

Localized electrical stimulation placed directly at the site of nerve pain, effective for pain in the shoulder, hip, knee, and extremities.

Neuromodulation

Procedure Overview

Not all nerve pain originates from the spinal cord. When pain is localized to a specific region of the body, a shoulder, a foot, the side of the hip, the nerve responsible is often a peripheral nerve, one that runs outside the spine entirely. Treatments targeting the spinal cord may not reach it. Peripheral nerve stimulation is designed specifically for that kind of pain.

Treatment Purpose

PNS places small electrical leads directly adjacent to the specific peripheral nerve causing the pain. Controlled electrical pulses modulate pain signal transmission without damaging the nerve. Unlike spinal cord stimulation, PNS targets the pain at its actual site of origin.

Appropriate Conditions

Complex Regional Pain Syndrome (CRPS)
Chronic peripheral neuropathy
Post-surgical nerve pain
Sciatica
Shoulder and hip nerve pain
Occipital neuralgia
Back and limb pain from peripheral nerve injury

Patient Considerations

PNS begins with a trial phase, temporary leads placed via a minimally invasive needle technique, with no surgical incision required. The trial runs for several days to weeks so you can evaluate the results before any permanent decision. Your physician will confirm during your consultation whether PNS is a suitable match for your specific condition and nerve location.

Treatment Process

The trial phase uses temporary leads placed near the target nerve in a 30 to 60 minute outpatient procedure. If the trial is successful, permanent leads are implanted in a similarly short outpatient procedure. Both phases are performed under local anesthesia. You go home the same day.

Frequently Asked Questions

How is PNS different from spinal cord stimulation?

PNS targets peripheral nerves at the site of pain origin, while SCS targets the spinal cord. PNS is often preferred for localized pain in specific body regions.

Is it reversible?

Yes. The device can be adjusted or removed if it does not produce adequate relief.

What are the risks?

Low risk. Potential complications include infection, lead migration, or skin irritation at the implant site.
