Dorsal Root Ganglion Stimulation (DRG)
A minimally invasive neuromodulation therapy designed to address focal nerve pain that has been difficult to reach with other treatments — with precision targeting at the dorsal root ganglion.
Who This May Help
DRG stimulation may be an option if you have been living with persistent pain concentrated in a specific area of the lower body — such as the foot, ankle, knee, hip, groin, or pelvis — that has not responded to physical therapy, medications, nerve blocks, or other interventional treatments. It is most commonly considered for patients with complex regional pain syndrome (CRPS) or pain following surgery in these regions, particularly when the pain is focal and difficult to address with broader therapies.
A consultation with our clinical team will determine whether you are a candidate.
How DRG Stimulation Works
The dorsal root ganglion is a small cluster of nerve cells located alongside the spine that acts as a relay station for pain signals traveling from a specific region of the body to the brain. DRG stimulation delivers gentle, low-level electrical impulses directly to this structure, interrupting pain signals before they reach the brain. Because each ganglion corresponds to a precise area of the body, this approach allows for highly targeted relief — a meaningful advantage for patients whose pain is concentrated in one location.
Before any permanent placement, patients undergo a trial period of five to seven days during which temporary leads are placed to allow the patient to experience the therapy in daily life. If significant relief is achieved, the permanent procedure is then performed through a small incision as a same-day outpatient procedure. Patients go home the same day.
What to Expect After the Procedure
Most patients return to light daily activities within a few days of the procedure. Some post-procedure soreness at the incision site is normal and typically resolves quickly. Relief often begins gradually, with many patients experiencing continued improvement over the following weeks and months.
Because DRG stimulation involves an adjustable implanted system, settings can be fine-tuned after placement to optimize results. Our clinical team will follow your progress and make any adjustments needed to improve your comfort over time.
