Peripheral Nerve Stimulation: Targeted Neuromodulation for Localized Pain

TL;DR

Peripheral nerve stimulation (PNS) delivers precisely targeted electrical pulses directly to a specific peripheral nerve — interrupting pain signals before they reach the spinal cord and brain. Unlike spinal cord stimulation, PNS targets the nerve closest to the pain source, making it ideal for localized conditions including post-surgical pain, nerve injuries, complex regional pain syndrome, and chronic limb pain. PNS devices are minimally invasive, reversible, and adjustable — providing drug-free pain control with a trial period before permanent implantation.

Key Features

  • Targets specific peripheral nerve
  • Minimally invasive lead placement
  • Trial period before permanent implant
  • Fully reversible and adjustable
  • FDA-cleared therapy
  • Outpatient procedure

Key Benefits

  • Drug-free, continuous pain control
  • Reduces opioid dependence significantly
  • Highly targeted — minimal systemic effects
  • Improves function and quality of life
  • Effective for treatment-resistant pain
  • Patient-controlled stimulation settings

How Peripheral Nerve Stimulation Works

Peripheral nerve stimulation works on the gate control theory of pain — the same neurological principle underlying all neuromodulation therapies. When electrical pulses are delivered to a peripheral nerve at the appropriate frequency and amplitude, they activate large-diameter A-beta sensory fibers that "close the gate" on pain signal transmission through smaller C-fibers and A-delta fibers, preventing nociceptive signals from reaching the brain.

Unlike spinal cord stimulation — which targets the dorsal columns of the spinal cord — PNS places the stimulating electrode directly adjacent to the specific peripheral nerve responsible for the patient's pain. This targeted approach provides highly localized pain control with minimal effect on surrounding structures, making it particularly effective for discrete nerve injuries, post-surgical neuromas, and regional pain syndromes.
