It is known from previous work that acupuncture stimulation modifies the somesthetic afferent to different extends depending on the acupoint studied. In this study, somatosensory evoked potentials of 21 healthy volunteers are recorded. When acupoint LI-4 (Hoku) is stimulated, it produces noticeable modifications, with a significant increase of latency and decrease of amplitude of the peaks which reflect the primary cortical afferent. Comparison of these results with the absence of changes when the experiment is repeated by stimulating a non-acupuncture point, ensures that the effects observed depend on the special quality of the acupuncture point stimulated and not on the mere repetitive stimulation on the skin.
从先前的研究工作可知，针刺刺激会根据所研究的穴位不同程度地改变躯体感觉传入。在本研究中，记录了21名健康志愿者的体感诱发电位。当刺激穴位LI-4（合谷）时，会产生显著变化，反映初级皮层传入的波峰潜伏期显著增加，波幅降低。将这些结果与刺激非穴位重复实验时无变化的情况进行比较，确保了观察到的效应取决于所刺激穴位的特殊性质，而非仅仅是对皮肤的重复刺激。
