The Transformative Benefits of DRG Therapy

In the world of chronic pain management, the advent of Dorsal Root Ganglion (DRG) Therapy has revolutionized the landscape, offering newfound hope to those suffering from persistent pain. This ground-breaking therapy presents a range of benefits that are making a significant difference in patients’ lives.

Understanding Chronic Pain

Chronic pain, defined as pain that lasts longer than six months, affects an estimated 11 percent of Americans, according to the National Institutes of Health. It is a complex and multifaceted condition, often triggered by injuries, infections, or a dysfunction in the nervous system.

One common condition associated with chronic pain is Complex Regional Pain Syndrome (CRPS). CRPS can be categorized into two types: CRPS-I, where there is no confirmed nerve injury, and CRPS-II, where nerve damage is evident. Both conditions can cause chronic pain characterized by various symptoms, including a burning or freezing sensation, throbbing or sharp pain, a feeling of pins and needles, numbness, or hypersensitivity to touch.

Traditional Pain Management Techniques

Historically, chronic pain management has largely relied on medications, including opioids, which can lead to addiction and overdose. Other traditional treatment plans may encompass physical therapy, psychological interventions, nerve blocks, and surgery.

A significant advancement in the treatment of chronic pain came with spinal cord stimulation, a method that uses a surgically-implanted device to send electrical signals to the spinal cord, blocking pain signals from reaching the brain. Although this technique has been beneficial for many, it did not provide a solution for all chronic pain sufferers.

The Emergence of DRG Therapy

The introduction of DRG Therapy has ushered in a new era in the field of pain management. The Dorsal Root Ganglion (DRG) is a cluster of nerves located on the outside of the spinal cord. Previously thought to have no connection to pain, researchers now understand that this nerve bundle plays a critical role in nerve pain for CRPS I and II patients.

In DRG Therapy, a surgical procedure is performed to implant a stimulator that targets the dorsal root ganglion, thereby relieving pain in the lower limbs linked to CRPS. The patient has a hand-held controller that can adjust the stimulation settings within defined limits.

Unveiling the Benefits of DRG Therapy

Superior Pain Relief

One of the primary benefits of DRG Therapy is its effectiveness in providing superior pain relief. A 2017 study published in the journal ‘Pain’ found that DRG stimulation was more effective at relieving pain than traditional spinal cord stimulation. The study revealed that 74.2 percent of patients experienced significant pain relief with DRG stimulation, compared to 53 percent who received traditional spinal cord stimulation.

Improved Quality of Life

Beyond pain relief, DRG Therapy also leads to an improved quality of life. Patients who undergo DRG stimulation often report enhanced mobility, reduced reliance on pain medication, and an overall improvement in their day-to-day living. This improvement can have profound effects on a patient’s mental health, relationships, and ability to engage in activities they enjoy.

Innovation in Healthcare Technology

DRG Therapy is a testament to Abbott’s commitment to spearheading innovative healthcare technology. The Proclaimâ„¢ DRG Neurostimulation System, developed by Abbott, is a cutting-edge device used in DRG Therapy. This technological advancement has made a significant impact on the treatment of chronic pain, bringing hope and relief to countless patients globally.

The Future of DRG Therapy

As the medical community continues to recognize the benefits of DRG Therapy, it’s expected that this treatment will become a more common solution for those living with chronic pain. This innovative approach to pain management represents a significant step forward in the ongoing mission to improve patient care and quality of life.


The benefits of DRG Therapy are providing a beacon of hope for those living with chronic pain. With its superior effectiveness in pain relief and the potential for an improved quality of life, this innovative treatment is truly transformative. While there is always more to learn and understand about chronic pain management, the advent of DRG Therapy offers a significant step forward towards a future where chronic pain can be effectively managed and controlled.


This field is for validation purposes and should be left unchanged.
