摘要： 本工作的目的为继续探讨皮肤感觉(电感受性、电痛觉)的暗示感受性和针刺镇痛的关系。被试为30例正常人。方法:针刺镇痛的效果是通过观察针刺对痛刺激引起的大脑诱发电位的抑制效应,以第一体感区的P_2次波幅变化为客观指标。暗示实验重复过去方法。主要结果:1)针刺能镇痛,针刺对多数被试(21/3D)能抑制痛刺激引起的大脑诱发电位。2)暗示后电感受性和痛阈均有提高(分别为31.26％和18.37％)3)暗示感受性高低和针刺抑制痛刺激引起的大脑诱发电位没有相关(P>0.50)。还看到被试对针刺能镇痛的信任程度与针效无关,提示暗示在针刺镇痛中不起主要作用。

Abstract: This study is a further research on the relations between the suggestibility of cutaneous sensations (electric touch sensibility, electric pain)and the effect of acupuncture on cerebral potentials evoked by painfulstimulation. The subjects were 30 normal adults. Method: The role of acupuncture analgesia was observed through theinhibitory effect of acupuncture on cerebral potentials evoked by painfulstimulation. The criterion used was the variation of amplitude P_2 in the firstsomatosensory area. The method in the suggestibility experiment was thesame as in the previous paper. Essential results: 1) Acupuncture yielded inhibitory effect on pain. The majority ofsubjects (21/30) have shown inhibitory effect of acupuncture on cerebralpotentials evoked by painful stimulation. 2) Both electrical touch and pain thresholds increased under euggestion(by an average of 31.26% and 18.37% respectively). 3) There is no correlation between the size of suggestibility andinhibitory effect of acupuncture on cerebral pentials evoked by painful stimulation. It seems that the trust of the subject in acupuncture analgesia had no relation to the effect of acupuncture. Inductive suggestion played noimportant role in acupuncture analgesia.
