Persistent focal pain
Pain remains functionally limiting despite appropriate conservative, rehabilitative, medication, or interventional treatment.
PERIPHERAL NERVE STIMULATION
Targeted neuromodulation closer to the source of pain.
Peripheral nerve stimulation (PNS) uses electrical stimulation near a selected peripheral nerve or nerve target to influence pain signaling. Depending on the condition and treatment strategy, therapy may be delivered through a temporary system or an implanted system.
TARGETED NEUROMODULATION
Different from spinal cord stimulation.
Rather than stimulating within the epidural space, PNS places a lead near a peripheral nerve or related nerve target associated with the painful region.
PNS has evolved into several treatment approaches. Some systems are designed for a defined temporary treatment period, including 60-day percutaneous therapy, while other systems are intended for longer-term implantation. The appropriate approach depends on the diagnosis, nerve target, clinical goals, and device-specific indications.
PATIENT SELECTION
Who may be a candidate?
PNS can be considered across a range of pain conditions, but the evidence differs by diagnosis and nerve target. Treatment begins with identifying a clinically meaningful target and determining whether PNS fits the overall treatment plan.
Identifiable nerve target
The history, examination, anatomy, and pain distribution support a peripheral nerve or related target that may reasonably be treated with stimulation.
Clinical fit
The potential role of PNS is considered alongside other reasonable treatment options, prior response to care, medical factors, and patient preferences.
Meaningful goals
The treatment plan focuses on improvement in pain, function, activity tolerance, and quality of life rather than any single measure alone.
TEMPORARY & IMPLANTED PNS
More than one treatment pathway.
Temporary PNS can provide stimulation for a defined treatment period without leaving a permanent implant. One contemporary approach uses a percutaneous lead for up to 60 days, after which the lead is removed.
Implanted PNS systems are designed for longer-term therapy and may use a trial or other selection pathway depending on the system, target, and clinical situation. These approaches should not be treated as interchangeable; device design, indications, and evidence vary.
EVIDENCE & EXPECTATIONS
The evidence depends on the condition and treatment approach.
Clinical studies and recent consensus guidelines support PNS for selected pain conditions, but the strength of evidence is not identical across diagnoses, nerve targets, or device types. Patient selection, an appropriate target, and realistic treatment goals remain central to deciding when PNS should be considered.
Target mattersPNS is most useful when the clinical picture supports an appropriate peripheral nerve or related target.
Therapy variesTemporary and implanted systems have different treatment pathways and should be considered individually.
Function mattersResponse is assessed through meaningful changes in pain, function, activity, and quality of life.
WHAT TO EXPECT
A targeted, image-guided approach.
Evaluation
The process begins by identifying the likely pain generator or nerve target, reviewing prior treatment, and determining whether PNS is a reasonable option for the clinical situation.
Lead placement
A stimulation lead is positioned near the selected nerve or target using image guidance when appropriate. Exact technique and treatment duration depend on the PNS system and anatomy being treated.
Follow-up
Response is assessed over time using pain, function, activity goals, tolerability, and overall progress. Next steps depend on the treatment pathway and the patient’s individual response.
FREQUENTLY ASKED QUESTIONS
Common questions about peripheral nerve stimulation.
Is PNS the same as spinal cord stimulation?
No. Spinal cord stimulation places leads in the epidural space to influence pain signaling at the spinal cord level. PNS places stimulation near a selected peripheral nerve or related nerve target. The therapies differ in their targets, systems, and patient-selection considerations.
Is peripheral nerve stimulation permanent?
Not necessarily. Some PNS systems provide therapy for a defined temporary treatment period, while others are designed for longer-term implantation. The appropriate approach depends on the condition being treated, nerve target, treatment goals, and device-specific considerations.
What conditions can PNS treat?
PNS has been studied for a range of pain conditions, including selected neuropathic pain syndromes, post-amputation pain, chronic shoulder or knee pain, and certain chronic back pain applications. The strength of evidence varies by condition and nerve target, so candidacy is determined through an individualized evaluation rather than from a broad diagnosis list alone.
Does temporary PNS always require a separate trial first?
No. Defined-duration PNS therapy, such as a 60-day percutaneous treatment, is itself a treatment pathway and is different from a temporary trial used before some longer-term implanted systems. The appropriate pathway depends on the device, nerve target, and clinical situation.
How do you know whether PNS is working?
Response is assessed using more than a pain score alone. Meaningful changes in function, activity tolerance, patient-specific goals, medication use when relevant, tolerability, and overall satisfaction may also help determine clinical benefit.
NEXT STEP
Could targeted neuromodulation be an option?
A focused evaluation can help determine whether there is an appropriate peripheral nerve target and whether PNS may be a reasonable part of your treatment plan.
