DRG Stimulation

  • Downtown Pain Physicians Accolades

If you suffer from chronic pain in your lower body including the foot, knee, hip, or groin area and you’ve been unable to find relief, you might benefit from DRG stimulation at Downtown Pain Physicians. Our physicians at both NYC area locations are experts in the treatment of pain and are very skilled in using DRG stimulation to directly stimulate the dorsal root ganglia (DRG) and prompt significant pain relief in patients.

Schedule a consultation with our pain relief specialists today and we’ll discuss your treatment options and listen to your history of pain and other symptoms you are experiencing. If you decide to proceed with treatment, we will use our state-of-the-art equipment to pinpoint your diagnosis and begin to explore possible treatment options best suited to your condition. One of those options might be DRG stimulation. Let’s take a deeper look and discover what DRG stimulation is, how it can help you overcome your pain, and what to expect from this treatment.

What Are Dorsal Root Ganglia (DRG)

Before we begin to define what DRG stimulation is and how it works, it makes sense to take a couple of steps backwards and look at the dorsal root itself and what its purpose is. Dorsal simply refers to something related to the back or upper side, in this case, the back of your spine.

Everyone has many dorsal nerve roots in their body that work to carry sensory information to the brain from other parts of the body. More specifically, they carry signals from the peripheral nervous system to the central nervous system.

To illustrate the role of your dorsal nerve roots, imagine you touch a hot stove with your hand. Your nerves at the tips of your fingers immediately send the “Ouch! This is hot!” message up to your dorsal root which then tells your brain that you are in danger and touching something hot. This happens so quickly and automatically that you’re not aware that it’s happening, which is a good thing, or you could be seriously injured.

That’s the dorsal root, but what about the ganglia? Ganglion is the singular, ganglia is the plural, either way these are areas where clusters of nerve cells are found. Sometimes called the spinal ganglion, they assist in the relay of information from the peripheral nervous system to the central nervous system.

What’s most beneficial and very fascinating about the DRG is that, although they house many different nerves, each one along the spinal column regulates nerves associated to its specific region of the body. It’s fairly easy for a trained specialist to determine which DRG is involved, based on pain symptoms, especially when the patient is experiencing chronic, isolated pain in the lower extremities.

What Is DRG Stimulation Therapy

DRG stimulation therapy focuses on where the dorsal nerve cluster comes together in the ganglia. Mild electrical pulses are sent to prespecified regions and can target parts of the body where the pain is located. These pulses interrupt the pain messages between the peripheral nervous system and the central nervous system. In effect, they scramble them, so your brain isn’t being told that you have pain.

Because the ganglia are easily accessible and predefined with the areas they connect, DRG stimulation can be very effective. Traditional spinal cord stimulation is fairly similar to DRG, but some types of pain and certain conditions don’t respond as well to traditional treatments as the more localized and specialized approach that DRG offers. The patient is also often pleased with the idea of only the targeted area being affected by the electronic stimulation.

How Does DRG Stimulation Work

Understanding DRG stimulation is a little easier when you understand the mechanics behind it and what’s happening within and even outside of the body. DRG stimulation requires surgery to place leads in the body on the targeted DRG. These electrical leads are insulated wires that carry the electrical pulse from a generator right to the DRG. The implantable pulse generator is usually situated in the body in the upper buttock or lower back region. In some cases, it’s placed in the abdominal wall.

The final key piece of equipment in DRG stimulation is a handheld device that the patient carries with them to control their stimulation. During episodes of pain, the stimulator can be “turned up” so the pain signals are blocked. The stimulator can be turned off completely if you’re not suffering pain at the moment. Some patients even have the ability to switch from one DRG to another if there are multiple regions involved in their chronic pain.

Do I Need DRG Stimulation

It’s best to consult with one of our pain specialists at Downtown Pain Physicians first before making any decisions. While this is an extremely effective form of therapy, it might not be the best one for you or our situation. Weighing all options when it comes to chronic pain is a key part of a responsible and effective treatment plan.

That said, DRG stimulation therapy might be right for you if you have:

  • Chronic pain lasting more than six months
  • Pain that is located in the lower part of the body (foot, knee, hip, or groin)
  • Pain that consistently appears in the same part(s) of the body and doesn’t radiate or move
  • Little or no relief from other, less aggressive pain management therapies
  • You’re interested in a reversible treatment option
  • You want to try to avoid spine surgery

If you have all of the above qualifications, DRG stimulation therapy might be a great option for you and give you relief from your chronic pain. To explore this option further, connect with our Downtown Pain Physicians offices if you live in the greater New York area for an appointment.
