Using the method of recording the corresponding dorsal root action potentials evoked by stimulating the acupoints, we found that electro-acupuncture could not only expand the segmental of potentials, but also amplitude the potentials. The results proved the acupuncture sensation may be transsegmental afferent after acupuncture along the meridians. This study gave a new evidence for the mechanism's explanation of propagated sensation along the meridians.
