How does spinal cord stimulation work to relieve pain?
For the treatment of chronic spinal pain, spinal cord stimulation or neurostimulation involves the stimulation of the spinal cord or peripheral nerve by tiny electrical impulses. An implanted lead (flexible insulated wire), which is powered by an implanted battery or by a receiver, is inserted into the epidural space near the spinal cord. This lead, powered by an implanted neurostimulator battery, sends electrical impulses that block the pain messages on their way to the brain. The pain is replaced by a mild tingling sensation. The stimulation can be adjusted in terms of strength and area of coverage via an external programming device. It may be felt as a small bulge under the skin, but does not normally show through clothing. How do I know if I am a candidate for a spinal cord stimulator? People with certain kinds of pain may be candidates for neurostimulation therapy. The following criteria are used to determine whether or not spinal cord stimulation is appropriate: • Spinal pain rad
