After manual acupuncture in the Neiguan point no significant difference was detected on early component N9, N13, N20, as well as, the negative potential after N20 from 22 subjects with normal SEP. However in one patient with abnormal SEP the latencies were sometimes improved after acupuncture when the acupuncture simultaneously decreased the pain.
对22名体感诱发电位（SEP）正常的受试者在内关穴进行手针针刺后，未检测到早期成分N9、N13、N20以及N20之后的负电位有显著差异。然而，在1名SEP异常的患者中，针刺有时会使潜伏期缩短，同时针刺也减轻了疼痛。
