Overview
PNS is designed for pain patterns linked to identifiable peripheral nerves. In some cases pain is localised and nerve driven but does not require stimulation at the spinal cord level. PNS places a small stimulation lead near the relevant nerve to influence pain signalling.
Depending on the system and indication treatment may be trialled first and then continued if benefit is clear. Your consultant will explain which approach applies to your condition.
Who This Treatment Helps
PNS may be considered for people with:
• Focal neuropathic pain linked to a specific peripheral nerve distribution
• Persistent pain after injury or surgery where a peripheral nerve is involved
• Pain that limits rehabilitation and function despite conservative care
• Defined pain areas suitable for ultrasound guided lead placement
• A diagnosis where nerve targeted stimulation is clinically appropriate
A consultation is required to confirm suitability and identify the most relevant nerve targets.
What Is Peripheral Nerve Stimulation
PNS involves placing a small lead near a peripheral nerve under imaging guidance commonly ultrasound. The lead connects to a stimulator that delivers gentle electrical impulses to reduce pain signalling.
The therapy aims to:
• Reduce pain intensity
• Improve tolerance to movement and rehabilitation
• Reduce flare ups in selected conditions
• Support return to activity
What to Expect During the Procedure Pathway
The pathway often includes:
-
Consultant assessment and pain mapping to identify the likely nerve target
-
Review of imaging and previous treatments
-
Lead placement under ultrasound guidance in a controlled setting
-
Programming and adjustment of stimulation to match your symptoms
-
Follow up review to assess benefit and functional outcomes
Your consultant will explain whether your system is temporary trial based or intended for longer term use.
After the Procedure and Recovery
After lead placement you may be advised to:
• Avoid excessive stretching or strain near the lead site for a short period
• Keep dressings clean and follow wound care advice
• Attend follow up to optimise stimulation settings
• Continue physiotherapy with improved comfort and pacing
Benefits
Potential benefits may include:
• Targeted therapy for focal nerve related pain
• Minimally invasive approach with short recovery time
• Adjustable settings tailored to your symptoms
• Improved function and participation in rehabilitation
• Potential reduction in medication use for some patients
Possible Risks and Side Effects
Risks may include:
• Infection
• Bleeding or bruising
• Local discomfort at the lead site
• Lead movement or loss of effective coverage
• Skin irritation from dressings or device components
• Rare nerve irritation
Your consultant will explain personal risks and how they are minimised.
When to Consider Other Options
PNS may not be suitable if:
• Pain is widespread or not nerve driven
• There is an untreated structural cause requiring a different approach
• Medical factors increase procedural risk
• Another neuromodulation option is more appropriate for your pain pattern
Alternatives may include targeted injections nerve blocks radiofrequency treatments spinal cord stimulation DRG stimulation or multidisciplinary pain management.
Safety Note
Please inform your consultant about blood thinners diabetes immune suppression allergies or any active infection. A structured assessment ensures the treatment is appropriate and safe. Ongoing follow up is important to optimise settings and outcomes.
Arrange a consultation to discuss whether peripheral nerve stimulation may be suitable for you.
