The effect of acupuncture analgesia on pain threshold was assessed in a group of 60 healthy volunteers. On the average a 60% elevation of the pain threshold was achieved. This effect was seen bilaterally with unilateral acupuncture stimulation. There was no significant difference in the effect produced by three widely separate sites of acupuncture stimulation. The possibility of an additive effect when two sites were simultaneously stimulated was not confirmed in our limited study. Evidence is presented that sensory nerve fibre stimulation may be the basic primary requirement of successful acupuncture analgesia.
在一组60名健康志愿者中评估了针刺镇痛对痛阈的影响。平均而言，痛阈提高了60%。单侧针刺刺激时双侧均可见此效应。三个相距甚远的针刺刺激部位所产生的效应没有显著差异。在我们有限的研究中，未证实同时刺激两个部位时存在累加效应。有证据表明，感觉神经纤维刺激可能是成功进行针刺镇痛的基本首要条件。
