Dorsal Root Ganglion (DRG) stimulation is an innovative neurostimulation therapy designed to manage chronic, localized pain, particularly in the lower body regions such as the foot, knee, hip, and groin. This cutting-edge treatment offers a new hope for those who haven't found relief through traditional methods. By precisely targeting the dorsal root ganglia, DRG stimulation can provide significant pain reduction. This technique works by delivering electrical pulses directly to the DRG, which are crucial structures within the spinal column that regulate sensations. The therapy aims to disrupt pain signals before they reach the brain, thereby offering relief and improving the patient's quality of life.

Understanding Dorsal Root Ganglia

Dorsal root ganglia (DRG) are clusters of sensory neurons located along the spinal column. These critical structures play a fundamental role in the body's sensory processing, acting as gateways for transmitting sensory information from the peripheral nervous system to the central nervous system. Each DRG is responsible for specific regions of the body, and they work collectively to regulate sensations such as pain, touch, and temperature. By understanding the unique role of each DRG, medical professionals can tailor treatments to target specific pain points effectively. This precise targeting is what makes DRG stimulation a promising solution for patients with chronic pain confined to particular areas. If you're struggling with neck pain, learning more about effective management techniques can be a game changer. By staying informed about neck pain management, you can take proactive steps towards a healthier, pain-free life.

How DRG Stimulation Therapy Works

DRG stimulation therapy involves stimulating the specific DRG associated with the area experiencing pain. The therapy comprises several key components:

  • Generator: An implanted device that sends electrical pulses.
  • Leads: Wires that carry pulses to the DRG.
  • Patient Controller: A handheld device that allows the patient to adjust the stimulation settings.

The therapy process begins with a trial period using temporary leads to determine the effectiveness of the treatment for the patient's specific pain condition. During this period, temporary leads are placed near the DRG to deliver electrical pulses. If the patient experiences significant pain relief, a permanent implantation procedure is then scheduled. 

The permanent implantation procedure involves placing the generator under the skin, typically in the lower back or abdomen, and positioning the leads to target the specific DRG. The patient controller allows the patient to fine-tune the stimulator, ensuring optimal pain relief. This personalized approach is what sets DRG stimulation apart from other pain management therapies, offering targeted relief where it's needed most.

If you're dealing with back pain, gaining knowledge about effective management strategies is essential for relief and recovery. By learning more about back pain management, you can take proactive steps toward a healthier, pain-free life.

Benefits of DRG Stimulation

Targeted Pain Relief

One of the primary benefits of Dorsal Root Ganglion (DRG) stimulation is its ability to provide targeted pain relief. This therapy is particularly effective for managing isolated areas of chronic pain, making it ideal for conditions such as lower extremity pain, complex regional pain syndrome (CRPS), and peripheral nerve. Unlike broader neurostimulation techniques, DRG stimulation focuses precisely on the affected nerves, offering more localized relief. This precise stimulator helps in significantly reducing pain with minimal extraneous sensations, ensuring that patients experience relief exactly where they need it most. The targeted nature of DRG stimulation also minimizes unwanted side effects, making it a highly effective and patient-friendly option for chronic pain management.

Advantages Over Traditional Spinal Cord Stimulation

DRG stimulation offers several advantages over traditional spinal cord stimulation (SCS), enhancing its appeal as a pain management solution. One of the standout benefits is its directed anatomical targeting, which allows for more specific pain relief. This precise approach ensures that the therapy is directed at the exact source of pain, increasing its effectiveness.

Additionally, DRG stimulation requires lower energy to function, leading to longer battery life for the implanted device. This means fewer replacements and less frequent surgeries, providing a more convenient and long-term solution for patients.

The risk of lead migration is also significantly reduced with DRG stimulation. The leads remain securely in place, maintaining consistent stimulation and reducing the likelihood of complications. Furthermore, DRG stimulator minimizes postural effects, delivering effective pain relief regardless of the patient’s body position. This stability ensures that patients receive continuous and reliable pain management, improving their overall quality of life.

The DRG Stimulation Procedure

Trial Period

The DRG stimulation procedure begins with a trial period that typically lasts between 5 to 7 days. During this period, temporary leads are inserted near the dorsal root ganglia to assess the therapy's effectiveness for the patient’s specific pain condition. This trial phase allows patients and doctors to evaluate the potential benefits of the treatment without committing to a permanent implant. If the trial period results in significant pain relief, the patient may then proceed to the permanent implantation process.

Permanent Implantation Process

The permanent implantation of the DRG stimulation system involves a few straightforward steps:

  • Two Small Incisions: The procedure starts with making two small incisions, one for lead placement and one for the generator implantation.

  • Lead Placement within the Epidural Space: Through the first incision, leads are carefully positioned in the epidural space, targeting the specific DRG associated with the patient's pain.

  • Generator Implantation: The second incision is used to implant the generator, typically in the upper buttock or abdomen. This small device generates the electrical pulses that are transmitted to the leads.

After the leads and generator are securely placed, the system is activated. The generator is programmed, and the patient receives training on how to use the patient controller. This handheld device allows the patient to adjust the stimulation settings, ensuring optimal pain relief.

The entire procedure is designed to be minimally invasive, with a focus on patient comfort and quick recovery. At NASPAC, our team is dedicated to guiding patients through each step, providing expert care and support to achieve the best possible outcomes.

Our Services

Radiofrequency Ablation

Also known as a rhizotomy, radio frequency ablations can provide long-term relief by ‘turning off’ nerve endings connected to arthritic facet joints. Overtime, the nerve endings will naturally heal, and the procedure can be performed as needed to give repeated relief.

Lumbar Epidural Injections

Lumbar Epidural Injections treat pain in the lower back or sciatica. The procedure reduces inflammation and allows for improved mobility and of the lower back and legs, so the patient can progress with their rehabilitation.

Cervical Epidural Steroid Injections

Cervical epidural steroid injections are aimed at treating neck pain derived from inflammation to cervical nerve roots. This can cause radicular pain down the arm and into the hand. CESI’s can provide short-term relief to help the patient with a rehabilitation or exercise regimen to progress further.

Lumbar Medial Branch Blocks

Lumbar medial branch blocks are used to determine the source of the patient’s lower back pain. If the patient experiences significant relief after the injection, then the procedure has successfully determined the source of the pain, and the patient can proceed with their rehabilitation regimen/additional procedures to achieve long term relief.

Cervical Medial Branch Blocks

Cervical epidural steroid injections are aimed at treating neck pain derived from inflammation to cervical nerve roots. This can cause radicular pain down the arm and into the hand. CESI’s can provide short-term relief to help the patient with a rehabilitation or exercise regimen to progress further.

Sacroiliac Injection

SI joint injections are aimed at treating lower back pain or sciatica. Sacroiliac joint dysfunction can be diagnosed after an SI injection if the patient reports immediate significant pain relief.

Biacuplasty

Biacuplasty is aimed at treating chronic disc-related pain. The procedure is a type of radiofrequency ablation (RFA) that uses two thin electrode probes which are inserted into the disc. While producing the electrodes, the probes and tissue are actively cooled, and provide for less discomfort.

Celiac Plexus Block

The celiac plexus is a nerve group surrounding the aorta. The block will stop the nerves from carrying pain information to your brain, and give you relief. This procedure is commonly performed on patients who experience abdominal pain linked to or derived from cancer.

Discogram

Discograms evaluate back pain by injecting a small amount of die into the soft center of the disc. An x-ray or CT scan can identify cracks and some spots of wear and tear.

Ganglion of Impar Block

Aimed at treating pain in and round the pelvic or groin area, a ganglion of impar injection is a sympathetic block to determine if the pain is derived from the injection site or is sympathetically medicated. This procedure is typically performed twice for confirmation.

Genicular Nerve Ablation

Another type of RFA , genicular nerve ablations are used to treat osteoarthritis in the knee. The procedure is minimally invasive and can provide adequate relief for patients.

Hypogastric Plexus Block

The hypogastric plexus is a bundle of nerves at towards the bottom of your spinal cord. Blocking these nerves is typically aimed at preventing pain derived from the lower digestive or reproductive systems, or sometimes cancer. Some patients will report immediate relief after the procedure, and long-term relief after a few days.

Joint Injections

A steroid joint injection is a common injection performed directly into the area the patient is reporting pain. The length of relief is different for each patient, but long-term relief is more likely with a working physical therapy or exercise regimen.

Intercostal Nerve Block

An INB is used for treating chest pain caused by a surgical incision or shingles (herpes zoster infection). When the steroid is injected into the intercoastal nerves, located under each rib, the inflammation of the tissue is reduced, providing relief. It is advised patients do not do heavy lifting or significant physical activity in the 24 hours after the injection.

Kyphoplasty

Kyphoplasty is necessary for patients who have a fracture from osteoporosis. A small balloon is surgically inserted into the vertebrae and inflated, which returns the structure to a more normal and more compact position.

Lumbar Sympathetic Block

Sympathetic blocks to the lumbar spine help relieve sciatica and/or chronic pain that radiates down the leg and into the foot.

Microdisectomy

Herniated discs create pressure on a spinal nerve root. A microdiscectomy removes the ‘bulge’ that is identified as the reason for lower back pain, sciatica and leg pain.

Minimally Invasive Lumbar Decompression

Spinal stenosis in the lower back is when the spinal canal is narrowed and nerve fibers compressed, which causes pain and numbness. MILD removes excess bone tissue and/or ligaments compressing on the spinal cord and causing the pain. Patients are advised to rest without heavy lifting or significant activity for a few days after this procedure.

Occipital Nerve Block

Migraines or chronic headaches are usually related to occipital nerve irritation. The occipital nerves are injected through the back of the head or neck, and patients can experience relief almost immediately.

Spinal Cord Stimulation Trial

A spinal cord stimulator is a device that is sends electrical impulses through electrodes placed where the patient would typically receive an epidural for their pain relief. When the patient experiences pain, they can use a remote control to activate the stimulator.

Vertiflex

Vertiflex is a implanted device that is used to treat patients with lumbar spinal stenosis. If pressure is being applied to the nerve roots, the vertiflex implant is placed within the spine to relieve the pressure, and relieve back and leg pain.

Stellate Ganglion Block

Pain traveling through sympathetic nerves in or around the neck can be treated with a stellate ganglion block. This injection is used for patients who experience causalgia, shingles, reflex sympathetic dystrophy or decreased blood flow to the heart.

Dorsal Root Ganglion (DRG SCS)

The dorsal root ganglion nerves connect the dorsal horn of the spinal cord, which contain sensory neurons, to the rest of the nervous system. Stimulating these nerves allows for greater precision when dealing with lower body pain.
