Overview
Some chronic pain conditions are confined to a specific area such as the foot knee groin pelvis or a particular region after injury or surgery. Traditional spinal cord stimulation can be very effective but in some focal patterns DRG stimulation offers more precise coverage.
The DRG contains nerve cell bodies responsible for transmitting sensory information. By stimulating this area the therapy aims to reduce abnormal pain signalling and improve function. As with other neuromodulation options DRG therapy typically includes a trial stage before considering a permanent implant.
Who This Treatment Helps
DRG stimulation may be considered for people with:
• Localised neuropathic pain in a defined region such as foot ankle knee groin or pelvic distribution
• Complex regional pain syndrome in selected cases
• Persistent pain after surgery or injury with a focal nerve distribution
• Pain that has not responded adequately to medication injections or rehabilitation
• A pain pattern suitable for targeted stimulation based on assessment
A consultation is required to confirm suitability.
What Is DRG Stimulation
DRG stimulation uses thin leads placed near the dorsal root ganglion of specific spinal nerve levels that correspond to the painful area. The leads connect to a small implanted pulse generator. The system delivers electrical stimulation designed to reduce pain signalling.
The ability to target specific levels allows more precise treatment of focal pain patterns.
What to Expect During the Procedure Pathway
The pathway typically includes:
-
Consultant assessment review of symptoms and pain mapping
-
Planning of which DRG levels match your pain distribution
-
Trial stimulation with temporary leads to confirm benefit
-
Review of trial results including pain reduction and functional change
-
If successful permanent implantation may be offered
Follow up programming is an important part of achieving stable coverage.
After the Procedure and Recovery
You may be advised to:
• Reduce bending twisting and heavy lifting temporarily
• Follow wound care instructions
• Attend programming sessions to optimise coverage
• Continue rehabilitation focused on function and gradual activity increase
Benefits
Potential benefits may include:
• Precise treatment for localised neuropathic pain
• Improved function and activity tolerance
• Reduced flare ups in selected patterns
• Adjustable therapy with a trial confirmation stage
• Potential reduction in medication reliance for some patients
Possible Risks and Side Effects
Risks may include:
• Infection
• Bleeding
• Lead movement or changes in stimulation coverage
• Local discomfort at implant sites
• Device related issues requiring reprogramming or revision
• Rare nerve irritation
Your consultant will discuss personal risks.
When to Consider Other Options
DRG stimulation may not be suitable if:
• Pain is widespread rather than localised
• There is an untreated structural cause requiring different treatment
• Medical factors increase procedural risk
• Goals and expectations do not align with likely outcomes
Other options may include spinal cord stimulation peripheral nerve stimulation targeted nerve blocks radiofrequency procedures or multidisciplinary management.
Safety Note
A full assessment is required including medication review and discussion of medical conditions such as diabetes blood thinners or immune suppression. Trial stimulation is used to confirm suitability before permanent implantation.
Arrange a consultation to discuss whether DRG stimulation may be suitable for your pain pattern.
