Understanding DRG Stimulation
The Dorsal Root Ganglion is a cluster of sensory nerves located tightly along the spine. It acts like a traffic light, regulating pain signals before they reach the spinal cord and brain. DRG stimulation targets this specific structure, rather than the entire spinal cord.
Hyper-Targeted Relief
Unlike traditional SCS which can cause unwanted stimulation in unaffected areas, DRG stimulation provides relief *only* where you need it—perfect for isolated foot, knee, groin, or pelvic pain.
Gold Standard for CRPS
Supported by the landmark ACCURATE study, DRG is an FDA-approved, highly effective treatment specifically indicated for Complex Regional Pain Syndrome (CRPS) Types I and II.
Superior Anatomical Stability
Because the DRG is encased in bone, leads placed here are far less prone to migration. This means your pain relief remains consistent even when you stand, sit, or move.
Your Pathway to Relief: DRG Trial & Implant
1. The Temporary Trial
Before committing, you get to “test drive” the therapy. Thin temporary leads are placed precisely over the DRG through a needle. For 5-7 days, you wear an external programmer to test the pain relief during daily activities.
Goal: Experience substantial reduction in your specific focal pain.>
2. Evaluation PhaseThe Trial
The temporary leads are gently removed in the office. You and Dr. Kalia will discuss your pain logs. If you experienced >50% relief and improved mobility, we move forward.
Data Check: Ensure the pain relief targeted the exact affected area.
3. The Permanent Implant
A minimally invasive outpatient procedure permanently places the micro-leads over the DRG. These are connected to a small, advanced internal battery (IPG) hidden under the skin, usually in the flank or buttock.
Goal: Experience substantial reduction in your specific focal pain.
