Peripheral nerve stimulation (PNS) places a small electrical lead near a selected peripheral nerve to modulate focal pain signaling.
PNS targets pain closer to the affected peripheral nerve rather than stimulating the spinal cord. Depending on the device and clinical problem, treatment may use a temporary system for a defined period or an implanted system for longer-term therapy.
Candidacy depends on the diagnosis, prior treatment, examination, imaging when appropriate, medical history, and the expected risk-benefit profile.
Focal neuropathic pain following a peripheral nerve distribution
Persistent pain after injury or surgery in selected patients
Function-limiting pain despite appropriate conservative care
A target nerve that can be safely approached under image guidance
Identify the likely peripheral nerve target
Confirm device strategy and clinical appropriateness
Image-guided lead placement near the target nerve
Programming, education, and follow-up
Potential risks include infection, bleeding, skin irritation, lead migration or fracture, uncomfortable stimulation, nerve irritation or injury, inadequate benefit, and need for repositioning or removal.
Results vary, and no procedure can guarantee pain relief or functional improvement.
