Stimulation with SCS not only reduces abnormal pain signals reaching the brain but also restores the normal pain-inhibition pathways that may have been lost. In these conditions the normal pain sensory and processing circuits of the spinal cord and brain are altered. ![]() Spinal Cord Stimulation’s Beneficial Function Other key uses are in the pain caused by ischaemia – a circulatory system problem involving an insufficient supply of oxygenated blood to tissues – such as in chronic critical limb ischaemia, refractory angina and some treatment-resistant vasculitis disorders that result from an inflammation of blood vessels.Īpart from neuropathic and ischaemic pain, SCS has been demonstrated in a number of cases of chronic visceral pain, such as in selected patients with chronic abdominal or pelvic pain, for instance, after major abdominal or pelvic surgery. The third is the pain associated with peripheral neuropathic pain caused by nerve damage beyond the spine or brain, for instance, from viral infection, trauma, surgery or diabetes. The second commonest indication is to treat the pain associated with complex regional pain syndrome. Increasingly SCS is used to avoid futile back surgery. SCS therapy is most commonly indicated in neuropathic back and leg pain, typically seen in 25% of patients following back surgery. The nerve damage may have occurred due to accident, injury, or disease. SCS is used to treat pain that is mostly neuropathic in origin, that is, pain that arises from nerve damage and does not serve a protective purpose. That number is expected to grow in order to manage a variety of chronic long-term conditions. The therapy now accounts for about 70% of all neuromodulation treatments. Food and Drug Administration (FDA) first approved SCS in 1989 to relieve chronic pain from nerve damage in the trunk, arms or legs. A further advance has been the awareness that pain reduction can be achieved without evoking perceptible sensations. Newer lead designs provide more precise control of the electrical field and increasingly sophisticated devices offer a variety of stimulation parameters. Since the therapy first entered routine use in the 1980s, advances have continued that enable more closely tailoring the therapy to a patient’s individual needs. First used to treat pain in 1967, spinal cord stimulation (SCS) delivers mild electrical stimulation to nerves along the spinal column, modifying nerve activity to minimize the sensation of pain reaching the brain.
