Dorsal Root Ganglion (DRG) therapy is an advanced treatment for chronic pain that provides highly targeted pain relief by stimulating specific nerves. It is particularly effective for pain in areas such as the foot, knee, groin, or lower back that may not respond well to other treatments.

DRG therapy works by delivering mild electrical signals to the dorsal root ganglion, a nerve cluster that plays a key role in processing pain. Unlike traditional spinal cord stimulation, which affects a broader area, DRG stimulation allows for more precise targeting of pain signals, reducing unnecessary stimulation in non-painful areas.

Research shows that DRG therapy is especially effective for nerve-related pain conditions, such as complex regional pain syndrome (CRPS) and chronic post-surgical pain after knee replacement, hernia repair, or amputation. Patients who have persistent pain after surgery, including SI joint fusion or foot and ankle procedures, may also benefit.

A DRG trial is required before permanent implantation. Patients first undergo a temporary trial to determine if stimulation provides at least 50% pain relief, which research shows is a strong predictor of long-term success. If the trial is successful, a permanent system is implanted to provide ongoing pain relief.

For those who qualify, DRG therapy can provide long-term pain relief, reduce reliance on medications, and improve mobility. If chronic nerve pain persists despite other treatments, DRG therapy may offer a more targeted approach to relief. Talk to your doctor to see if this treatment is right for you.
