Based on the observation that repeated acupoint stimulation elicits evoked potentials whose latency varies as a result of the stimulus intensity we assessed the evoked potential elicited by stimulus of three acupoints (Hegu, Shenmen and Houxi), comparing the results to the potentials produced by median nerve stimulus and nonacupunctural point. Fourteen healthy individuals were studied, and no modifications related to the Hegu and Shenmen point potentials increased with the amount of stimuli, until it reached a plateau at around 400 stimuli. It did not vary for Houxi and the nonacupunctural point. We conclude that the somesthesic afference from acupunctural points must involve control circuits that are quantitatively different for each point.
基于重复穴位刺激会引发诱发电位，且其潜伏期会因刺激强度而变化这一观察结果，我们评估了三个穴位（合谷、神门和后溪）刺激所引发的诱发电位，并将结果与正中神经刺激和非穴位产生的电位进行比较。对14名健康个体进行了研究，合谷和神门穴电位未随刺激量增加而发生变化，直至在约400次刺激时达到平台期。后溪穴和非穴位的电位没有变化。我们得出结论，穴位的躯体感觉传入必定涉及对每个穴位而言在数量上有所不同的控制回路。
