Spinal Cord Stimulation for Parkinsonism

Spinal cord stimulation (SCS) is a very thin electrode implanted in the dorsal epidural space of the spinal cord to improve the patient's symptoms by stimulating the spinal nerves with pulsed electrical currents, which attenuate or enhance the flow of nerve impulses from the periphery to the central system, i.e., stimulating thick fibers to achieve therapeutic results. SCS system consists of three components: an electrode implanted in the epidural space of the patient's spinal cord, a stimulator implanted subcutaneously in the abdomen or buttocks that delivers electrical impulses, and an extension cord that connects the two.
