摘要: Previous studies have shown that muscle exercise and low frequency transcutaneous nerve stimulation (TNS) give rise to an analgesic effect in humans animals. Endorphin has been proposed mediate this analgesia. In investigation, the of TNS, on dental pain thresholds was studied possible involvement endorphinergic mechanisms investigated using naloxone as antagonist. Dental were measured 11 volunteers following leg or arm after TNS hands face. After (20 min) (30 either 0.8 mg (2 ml) saline injected i.v. a double-blind fashion. Pain repetitively before stimulation. Both increased threshold. Stimulation also threshold, but less than exercise. A marked increase threshold seen face These changes unaffected injections saline, except for early short-lasting reduction when The increases showed similarities suggesting common mechanism might be involved. could only partially mediated by mechanisms.
