Peripheral Nerve Stimulator (PNS)
Peripheral Nerve Stimulation (PNS)
Peripheral nerve stimulation delivers electrical stimulation to a selected peripheral nerve to modulate pain signaling. PNS is considered for focal, diagnosis-specific peripheral nerve pain rather than as a general treatment for every chronic pain condition.
Who May Be Considered?
Depending on the device and clinical indication, PNS may be considered for selected peripheral neuropathic pain, postsurgical or post-traumatic nerve pain, and certain focal pain conditions when conservative care has not provided adequate benefit. The target nerve and pain distribution should be clearly defined.
Temporary and Longer-Term Systems
PNS systems differ. Some are designed for a temporary treatment period, while others use longer-term implanted components. Not every PNS therapy requires a traditional 5–7 day trial followed by permanent implantation. Device selection and treatment duration depend on the system, indication, anatomy, payer requirements, and patient goals.
Expected Results and Risks
The goal is meaningful improvement in pain and function, not guaranteed elimination of pain. Potential risks include infection, bleeding, skin irritation, lead migration or fracture, uncomfortable stimulation, nerve irritation or injury, device malfunction, and inadequate benefit.
Clinical Evidence, Limitations & Patient Selection
PNS evidence is indication- and device-specific. Modern PNS includes temporary treatment systems as well as longer-term implants, so the treatment pathway should match the actual device being used.
Important limitation: PNS should target a defined peripheral nerve/pain distribution rather than be presented as an implant for every treatment-resistant pain condition.
Every procedure has potential risks, and individual benefit cannot be guaranteed. Recommendations at Solutions in Pain are based on the diagnosis, examination, relevant imaging, prior treatment, medical history, medications, patient goals, current evidence, and applicable payer requirements.
