耳与经脉相关是经络学说的组成部分之一。近年来

人们从经络现象方面研究耳与十四经脉的关系

做了大量工作。然而

值得提出的是耳穴诱发感传有无特异性

即刺激耳壳上临床常用的脏腑点所诱发的感传线

它是沿着相应的经脉循行(如耳穴心区诱发心经感传、胃区诱发胃经感传)或不相应的其他经脉感传循行

众说不一

报道互有差别。上海市耳针协作小组观察的耳穴放射感中

27条足太阳膀胱经属刺激耳穴坐骨神经者9条

其余是耳穴大肠、肺、内分泌等

没有显示明显的特异性;广西中医学院针麻经络研究室报告:104次测试中

In 12 propagated sensitive persons

we have observed 202 times of stimu- lation on the visceral regions of auricule and 138 times of stimulations on non-visceral areas to induce the P S C. It shows that the auricular point has no specific relation to the propagated sensation lines appeared

but still there are some rules and relation existes obviously most of propagated sensation lines run along the the 12 channels. On the other hand

a single auricular point may induce a lot of PSC on the 12 channels and different auricular points also induce the same line of PSC.Both di- splay a phenomena of coordination and combined with the function. PSC was imduced on auricular points to appear the same line or difference by repeated stimulation. Thus it expresses the variability and a relative stability in the function. The above may be valuable for detecting PSC and aurioular therapy
