![]() ![]() Because of this, the DRG might be an attractive target for electrical stimulation. The DRG houses the cell bodies of sensory neurons and is an active participant in the development of certain forms of chronic pain 8, 9, 10, 11, 12, 13. The dorsal root ganglion (DRG) is located at both sides of the spinal cord on the distal end of the dorsal root in the lateral epidural space. Spinal nerves, formed from afferent sensory axons (the dorsal root) and motor efferent axons (the ventral root), emerge from the intervertebral neural foramina between adjacent vertebral segments 7. Nociplastic pain is a relatively new term the International Association for the Study of Pain describes it as “altered nociception despite no clear evidence of actual or threatened tissue damage causing the activation of peripheral nociceptors or evidence for disease or lesion of the somatosensory system causing the pain” 6. Nociceptive pain arises from harmful stimuli to non‐neural tissue and is due to the activation of nociceptors 6. Neuropathic pain is caused by a lesion or disease of the somatosensory system. ![]() Chronic pain has a wide range of etiologies that can be neuropathic, nociceptive, or nociplastic in nature 5, 6. Post‐surgical complications and trauma (25%) and spine problems (20%) are responsible for almost half the incidence of chronic pain 4. It is often a debilitating condition that substantially diminishes quality of life. ![]() Chronic pain affects approximately 20–30% of the population in the United States and Europe 2, 3. Chronic pain is defined as pain persisting past normal healing time, lasting or recurring for more than six months 1. ![]()
