Transcutaneous electrical analgesia: A follow-up analysis

Abstract
One year follow-up data were analyzed for the effects of using transcutaneous neurostimulators on patients with chronic benign pain. Those who had successful surgery for pain relief had lower pain and analgesic intake levels than those who supplemented their surgery with neurostimulation. Those who did not receive surgery for pain but use neurostimulators had greatly increased activity levels than those who did not use these devices. The neurostimulators lowered the clinical pain level component of the tourniquet test score for non-surgery patients to a degree comparable to that of patients with successful surgical outcomes, but maximum pain tolerance was not significantly altered. The analgesic effect is probably primarily a peripheral one.
