Wireless Peripheral Nerve Stimulation (PNS)

Wireless Peripheral Nerve Stimulation (PNS) is a minimally invasive therapy that uses gentle electrical impulses to calm overactive peripheral nerves and reduce chronic pain. By placing a small, flexible lead near the affected nerve and powering it wirelessly through an external transmitter, PNS offers targeted relief without the need for a permanently implanted generator. This therapy can significantly improve function and quality of life for patients with chronic nerve-related pain that has not improved with conservative treatments.

Quick facts

  • Setting: Outpatient, minimally invasive
  • Time: ~45–60 minutes
  • Anesthesia: Local with light sedation
  • Recovery: Resume light activity within 24 hours
  • Duration of relief: Can provide long-term improvement, even after lead removal

Who it helps

  • Chronic pain following surgery or injury
  • Peripheral nerve pain affecting the shoulder, arm, knee, foot, or back
  • Complex Regional Pain Syndrome (CRPS)
  • Neuropathic pain focused in a specific nerve distribution
  • Patients seeking alternatives to long-term medication or invasive surgery

How it works

Peripheral nerves carry signals between the brain and the rest of the body. When a nerve becomes damaged or overly sensitive, it can continue sending persistent pain signals. During wireless PNS therapy, a small micro-lead is placed through a needle near the painful nerve using ultrasound or fluoroscopic guidance. The external transmitter powers the lead wirelessly, delivering precise electrical pulses that disrupt abnormal pain signaling. Unlike traditional neurostimulation systems, wireless PNS does not require implantation of a battery or internal generator.

What to expect

  • Before: Your provider will evaluate your symptoms and imaging to ensure your pain originates from a specific peripheral nerve. Light sedation may be provided for comfort during placement.
  • During: A thin lead is inserted through a needle near the targeted nerve using real-time imaging. Once properly positioned, the lead is secured and connected wirelessly to an external transmitter worn on the skin.
  • After: You’ll go home the same day and begin using the external stimulator to manage pain. Therapy typically continues for several weeks. Many patients experience lasting pain relief even after the lead is removed.

Benefits & risks

Benefits:

  • Minimally invasive with no implanted battery
  • Offers targeted pain relief for specific nerve distributions
  • Reversible and adjustable therapy
  • May reduce reliance on pain medications
  • Can provide long-lasting improvement after treatment ends

Risks:

  • Temporary soreness or bruising at the insertion site
  • Lead migration or displacement (uncommon)
  • Skin irritation from external transmitter
  • Infection (rare)

Is it right for me? (Checklist)

  • ✅ Pain localized to a specific nerve or region
  • ✅ Poor response to medications, injections, or therapy
  • ✅ Desire for a minimally invasive, reversible treatment
  • ✅ Open to using an external wireless device during therapy

FAQs

  • How long is the therapy period? Treatment typically lasts 4–8 weeks, depending on your response.
  • Will I feel the stimulation? Some patients feel a mild tingling sensation; others experience relief without noticeable stimulation.
  • Is the device noticeable? The external transmitter is lightweight and worn discreetly on the skin.
  • Do leads stay in permanently? No—the micro-lead is removed after the treatment period.
  • Is it covered by insurance? Many insurance plans, including Medicare, cover PNS for approved indications.
