Spinal cord stimulation (SCS) has become a standard treatment for patients with chronic pain in the trunk and/or limbs, who have not found pain relief from other treatments. It has been established as a safe and effective treatment for pain from a wide variety of etiologies including failed back surgery syndrome (FBSS), intractable low back and leg pain, complex regional pain syndrome (CRPS) type I and II, and neuropathic pain. Potential outcomes of this treatment include increased ability to participate in normal home and work activities and decrease or cessation of pain medications after undergoing spinal cord stimulation. Given these benefits, there has been ongoing investment and advances in the technology.
