Dorsal Root Ganglion Stimulator
Dorsal Root Ganglion (DRG) stimulation is an advanced form of neuromodulation therapy used to treat chronic nerve-related pain that has not responded to other treatments.
The dorsal root ganglion is a cluster of sensory nerves located near the spine that controls pain signals from specific areas of the body.
In this procedure, a small device is implanted to send mild electrical signals to the targeted nerve, helping block or modify pain signals before they reach the brain.
Unlike traditional spinal cord stimulation, DRG therapy is highly precise and targeted, making it especially effective for pain in specific areas.
What Conditions Does This Treatment Help?
- Complex Regional Pain Syndrome (CRPS)
- Chronic neuropathic pain
- Post-surgical nerve pain (groin, knee, hip, foot)
- Peripheral nerve injuries
- Focal lower body pain (foot, ankle, knee, groin)
How Does DRG Stimulation Work?
DRG stimulation works by interrupting pain signals at a very specific point in the nervous system:
- The dorsal root ganglion acts as a gateway for pain signals traveling to the brain
- A small implanted device sends controlled electrical pulses to this area
- These pulses modify or block pain signals, reducing the sensation of pain
Because each DRG corresponds to a specific body region, the therapy allows for highly targeted pain relief compared to traditional methods.
What to Expect During the Procedure
Before the Procedure
- Comprehensive evaluation and imaging
- Trial stimulation may be performed to test effectiveness
During the Procedure
- A minimally invasive procedure using imaging guidance
- Thin leads are placed near the dorsal root ganglion
- A small pulse generator is implanted under the skin
- Procedure typically takes 1–2 hours
After the Procedure
- Same-day or short outpatient stay
- Mild soreness at the implant site
- Device settings can be adjusted using a handheld controller
Benefits of DRG Stimulation
✔ Highly targeted pain relief
✔ Effective for difficult-to-treat nerve pain
✔ Minimally invasive and reversible
✔ Adjustable stimulation based on patient needs
✔ Can reduce reliance on medications
Studies show many patients experience significant improvement in pain and function, especially for localized pain conditions.
Who Is a Good Candidate?
- Have chronic nerve pain lasting 6 months or more
- Have pain localized to a specific area (e.g., foot, groin, knee)
- Have not responded to medications, injections, or therapy
- Are not a candidate for or want to avoid major surgery
Risks & Side Effects
- Temporary soreness at the implant site
- Infection or bleeding (rare)
- Lead movement or device-related issues
- Need for device adjustment or revision
When Is This Treatment Recommended?
- Conservative treatments have failed
- Pain is chronic and nerve-related
- Pain is localized and severe
- Other interventional treatments have not worked
Recovery & Results
- Recovery is typically quick with minimal downtime
- Many patients notice improvement soon after activation
- Pain relief may continue to improve over weeks
- Long-term relief is possible with proper device management

FAQs
Leads are thin insulated wires placed around the dorsal root ganglion that carry electrical pulses from the generator to the nerves that send pain signals.
It can treat chronic back pain, neuropathic pain, abdominal pain, pelvic pain, groin pain, CRPS, phantom limb pain, and peripheral neuropathy.
The controller allows patients to adjust pain relief by increasing, decreasing, or turning off the stimulation based on their comfort.
Yes, the therapy is effective for chronic pelvic pain and groin pain that may not respond well to other treatments.
Yes, phantom limb pain (post-amputation pain) is one of the conditions that may benefit from DRG stimulation.
