Evoked potential assessment of acupunctural analgesia: attempted reversal with naloxone

摘要: The effects of electrical acupunctural stimulation (2 Hz) on pain judgments and evoked potentials are reported for two experiments using dental dolorimetry. In the first experiment subjects received acupuncture at points located in same neurologic segment as test tooth. second hands meridians. both instances resulted a reduction intensity smaller potential amplitudes, but naloxone neither reversed analgesia nor did it affect potentials. A pilot study was carried out to determine whether manual rather than would produce an reversible by naloxone, failed do so. These findings contribute growing evidence that significantly reduces sensibility volunteers undergoing dolorimetric testing, they not support hypothesis endorphin release is mechanism which exerts analgesia.
