The correlation between the effects of acupuncture (A) and hypnosuggestion (H) on subjective pain perception was studied in normal volunteers using somatosensory evoked potentials technique. Both methods influenced identically the subjective pain perception and affected the evoked cortical responses similarly. In those subjects in whom analgesia was achieved, location of the A needles proved unimportant and the suppression of the cortical response elicited by A or H was identical. This could be explained by cortically induced inhibitory activity in descending control systems for both methods. A. analgesia thus appears to be a suggestive modality which depends on individual susceptibility. A specific cultural background also seems to be of importance.
运用体感诱发电位技术，在正常志愿者中研究了针刺（A）和催眠暗示（H）对主观疼痛感知的影响之间的相关性。两种方法对主观疼痛感知的影响相同，对诱发的皮层反应的影响也相似。在那些实现镇痛的受试者中，针刺部位并不重要，针刺或催眠暗示引起的皮层反应抑制是相同的。这可以用两种方法在下行控制系统中皮层诱导的抑制活动来解释。因此，针刺镇痛似乎是一种依赖个体易感性的暗示方式。特定的文化背景似乎也很重要。
