Practice Parameters for the Use of Spinal Cord Stimulation in the Treatment of Chronic Neuropathic Pain

Pain Relief

Pain relief is the primary outcome measure of SCS success, with the arbitrary criterion of a 50% reduction in pain commonly used as the threshold for success.  This may be reported by the patient directly, as a percentage, or it may be calculated from numeric (e.g., 0-10) or visual analog scales.  The results of these different measures might vary in the same patient; in any event, no measure of pain relief has been shown to be an absolute criterion for success or for proceeding to a permanent implant.  Pain relief should be considered along with other outcomes.
