The percentage of subjects with paresthesia-free pain relief increased from 16.4% at 1-month to 38.3% at 12-months. Predictor variables for the presence or absence of paresthesias with DRG stimulation were also explored. Outcomes of subjects who were paresthesia-free were compared to those who experienced paresthesia-present therapy at 1, 3, 6, 9, and 12-month follow-ups. those who experienced the sensation of paresthesia, as well as the factors that predicted paresthesia-free analgesia.Ī retrospective analysis of therapy outcomes was conducted for 61 subjects in the ACCURATE study who received a permanent DRG neurostimulator. The present study explores treatment outcomes for DRG subjects who were paresthesia-free vs. Investigators noted that DRG stimulation programming could be adjusted to minimize, or eliminate, the feeling of paresthesia while maintaining adequate pain relief. 17 Marcus Neuroscience Institute, Boca Raton, FL, USA.ĪCCURATE, a randomized controlled trial comparing dorsal root ganglion (DRG) stimulation to spinal cord stimulation, showed that DRG stimulation is a safe and effective therapy in individuals with lower extremity chronic pain due to complex regional pain syndrome (CRPS) type I or II.16 Drug Studies America, Marietta, GA, USA.14 Evolve Restorative Center, Santa Rosa, CA, USA.13 Newport Beach Headache and Pain, Newport Beach, CA, USA.12 Carolinas Pain Institute, Winston-Salem, NC, USA.11 Florida Pain, Merritt Island, FL, USA.10 Pain Management Associates, Independence, MO, USA.8 Abbott Neuromodulation, Plano, TX, USA.7 Premier Pain Center, Shrewsbury, NJ, USA.5 IPM Medical Group, Inc., Walnut Creek, CA, USA.4 Department of Anesthesia, University of California, San Francisco, CA, USA.3 Volta Research and University of Illinois College of Medicine, Chicago, IL, USA.2 Center for Pain Relief, Charleston, WV, USA.1 Evidence-based Pain Management Research Department, Cleveland Clinic, Cleveland, OH, USA.The spinal cord stimulator is not indicated for severe depression. Patients seeking spinal cord stimulator treatments usually have failed all the other conservative treatments, such as medication, physical therapy, and nerve blocks with anesthetics and/or corticosteroids. The value of SCS for amputation stump pain, phantom limb pain and spinal cord injury is yet to be established. Some authors have reported treatment of severe peripheral neuropathy and post-herpetic neuralgia with SCS. Recent studies have indicated that SCS may also improve pain caused by a refractory angina and improve circulation in the coronary arteries. SCS is indicated for failed back surgery syndrome, complex regional syndrome, and unremitting pain due to peripheral vascular disease. Inhibitory neurotransmitters such as gamma- aminobutyric acid (GABA) may also be involved. When the dorsal column of the spinal cord is stimulated, it may attenuate the conduction of the pain signal on the spinothalamic tract through collateral inhibition. However, it is believed that the gate-control theory of pain conduction plays a major role. The spinal cord stimulation (SCS) (dorsal column stimulation) utilizes an electrodes placed in the epidural space, immediately behind the spinal cord, to stimulate the dorsal column of the spinal cord.
