A spinal cord stimulator is a specialized device that stimulates the spinal cord and spinal nerves by tiny electrical impulses via a small electrical wire placed behind and just outside the spinal cord in the epidural space. Spinal cord stimulators are most often used for patients with chronic and severe neuropathic pain, who have not responded to other more conservative treatments. Neuropathic pain is pain due to damaged nerve tissue. Common examples include patients with post-laminectomy nerve damage, radiculopathy, diabetic neuropathy and reflex sympathetic dystrophy. A spinal cord stimulator generates a low level electric field to interrupt nerve conduction of pain signals to the brain.
