Dorsal root ganglion stimulation.
DRG stimulation is an innovative neurostimulation therapy for chronic, localized pain — especially in the lower body, like the foot, knee, hip, and groin. By delivering gentle electrical pulses to the dorsal root ganglia, it interrupts pain signals before they reach the brain, offering hope when other treatments haven't worked.
What to expect
Precision relief, right where you hurt.
The dorsal root ganglia are clusters of sensory neurons along the spinal column. Each one handles sensation for a specific region of the body — which is what makes DRG stimulation so precise.
Targeting one painful area
Because each dorsal root ganglion maps to a specific part of the body, the therapy can focus exactly on the area that hurts — without spreading stimulation to places that don't. That makes it especially good for pain confined to one region.
- A small implanted generator sends electrical pulses
- Thin leads carry those pulses to the targeted DRG
- A handheld controller lets you adjust the settings
Advantages over traditional SCS
Compared with traditional spinal cord stimulation, DRG stimulation offers directed anatomical targeting, lower energy use for longer battery life, a reduced risk of lead migration, and consistent relief regardless of body position.
- Ideal for CRPS, lower-extremity, and peripheral nerve pain
- Lower energy means fewer battery replacements and surgeries
- Minimal postural effects keep relief consistent
From trial to lasting relief.
Trial period
Temporary leads are placed near the DRG for about 5 to 7 days to see whether the therapy relieves your specific pain.
Two small incisions
If the trial works, permanent leads are placed in the epidural space and a small generator is implanted, typically in the upper buttock or abdomen.
Activate & program
The system is switched on and programmed. The implant surgery itself usually takes about 1 to 2 hours.
Take control
You're trained on the handheld patient controller so you can fine-tune your stimulation for optimal relief.
Frequently asked questions
Is DRG stimulation FDA-approved?
Yes. DRG stimulation is FDA-approved for the management of chronic, intractable pain in the lower limbs, underscoring its safety and effectiveness.
How long does the implant surgery take?
The implant surgery typically takes around 1 to 2 hours. It's minimally invasive, allowing for a relatively quick recovery.
What are the potential risks or side effects?
As with any procedure, possible risks include infection, bleeding, lead migration, or pain at the implant site. Serious complications are rare, and most side effects can be managed effectively.
How long does the battery last?
Battery life varies with usage but generally lasts between 5 and 10 years. The device's low energy requirements contribute to its extended battery life.
Can the stimulation settings be adjusted?
Yes. You can easily adjust the settings using a handheld patient controller to customize your therapy for optimal relief.
Is DRG stimulation covered by insurance?
Most major insurance providers cover DRG stimulation therapy, though coverage can vary. Check with your insurance company to understand your specific benefits.
