Spinal cord stimulation(SCS) was first attempted to relieve intractable pain in 1966. SCS has evolved into percutaneously implanted electrode with aim of activating spinal pain-inhibiting mechanism via dorsal columns. SCS is valuable for the treatment of many painful and difficult to treat conditions such as postamputation pain, painful peripheral neuropathies, chronic sciatic pain and so on. We treated a case of causalgia of the right lower extremity with successful outcome of 90% sustained relief of pain. And patient has satisfied using SCS(Model MNR-94, Neuromed) for 6 months follow-up.
