Chronic nerve pain can make walking, sleeping, and everyday activities difficult. When other treatments haven’t provided enough relief, dorsal root ganglion stimulation, or DRG stimulation, may offer another option for certain people.
This treatment targets nerve structures associated with a specific painful area. At Pain Consultants of East Tennessee, an evaluation can help determine whether this approach fits your diagnosis and treatment goals.
What Is DRG Stimulation?
The dorsal root ganglion is a cluster of sensory nerve cells near the spine. These cells help carry sensory information, including pain signals, from the body toward the brain.
DRG stimulation uses thin wires called leads and a small implanted device to deliver electrical pulses near selected nerve clusters. These pulses change how pain signals travel through the nervous system.
Unlike conventional spinal cord stimulation, DRG therapy targets individual dorsal root ganglia. This approach can help focus stimulation on a particular painful area.
Who May Benefit From DRG Therapy?
In the United States, approved use includes adults with moderate to severe, persistent pain in the lower limbs associated with complex regional pain syndrome, or CRPS, types I and II.
CRPS type II is also known as causalgia and involves a known nerve injury.
However, the location of your pain alone doesn’t determine whether you qualify. Your specialist will consider your diagnosis, previous treatments, overall health, and ability to use the device.
Potential Benefits of DRG Stimulation
Focused Treatment
DRG therapy can direct stimulation toward nerve structures associated with a specific area of pain. This precision may be useful for certain types of localized lower-limb pain.
Adjustable Settings
Your care team can program the device and adjust its settings to help balance pain relief and comfort.
A Trial Before a Permanent Implant
A temporary trial allows you and your specialist to evaluate the treatment before deciding whether to proceed with a permanent device.
Support for Everyday Function
For some people, reduced pain may make daily activities easier. Nevertheless, results vary, and treatment does not guarantee pain relief or a return to every activity.
What Happens During the Trial?
During a trial, your specialist places temporary leads near the selected nerve structures and connects them to an external device.
You’ll track changes in your pain and discuss how the treatment affects daily activities. Your care team will also explain temporary activity restrictions and how to care for the trial equipment.
Afterward, you and your specialist will review the results. A helpful trial may support moving forward, although it cannot guarantee long-term success.
What Are the Risks and Limitations?
DRG stimulation involves procedural and device-related risks. These include infection, bleeding, nerve injury, movement of the leads, and discomfort around the implant.
Some people experience tingling or uncomfortable stimulation. Others may receive inadequate relief or need additional procedures to adjust, replace, or remove parts of the system.
Your specialist will explain these considerations before you decide.
Discuss DRG Stimulation With PCET
If you have persistent, localized nerve pain despite previous treatment, ask whether DRG stimulation is appropriate for your condition.
