The success rate for traditional SCS was (56.7%). Participants receiving DRG stimulation had a higher rate of treatment success (81.2%). The results of the ACCURATE research are quite impressive. One group received DRG stimulation therapy and the other received standard spinal cord stimulation. The participants were randomly placed into two groups.
The study recruited 152 subjects, each of whom had been diagnosed with chronic complex regional pain syndrome in their legs. The ACCURATE study was conducted at 22 investigational sites spread across the United States. The FDA approved DRG stimulation from the results of the ACCURATE study DRG stimulation is proved through studies to better disrupt pain signals on their way to the brain. Dorsal root ganglions are the sensory gate for pain signals sent to the brain along the spinal cord.
In DRG stimulation, the electrical pulses travel directly to nerve cells known as dorsal root ganglions located on the sides of each vertebra in the spine. In traditional SCS stimulation, electrodes are placed, and pulses are emitted, along the length of the spinal cord. While DRG stimulation is similar to spinal cord stimulation, it varies in significant respects. In February 2016, the FDA approved a new pain relief technique called dorsal root ganglion (DRG) stimulation. What is dorsal root ganglion stimulation? For example, more than half of CRPS patients fail to achieve any meaningful pain relief with SCS. SCS is also used to relieve peripheral neuropathic pain related to nerve damage from viral infection, surgery, or diabetes.īut spinal cord stimulation is not a panacea for patients suffering from CRPS or failed back surgery syndrome. The second most common application of SCS is to alleviate the intolerable pain associated with complex regional pain syndrome (CRPS). SCS therapy essentially tricks the brain into feeling only numbness or a mild tingling sensation, instead of the constant searing agony of incurable chronic pain.Ĭurrently, the primary use of SCS is to help avoid a back surgery that may prove to be futile. The pulses interrupt pain signals before they reach the brain. SCS works by sending mild electrical pulses to nerves along the spinal column. How does spinal cord stimulation therapy work for chronic pain? The FDA approved spinal cord stimulation in 1989 for the relief of intractable pain in the torso, arms, and legs. 
Spinal cord stimulation (also known as “SCS”) therapy has been used to combat chronic pain since 1967.
