皮肤阻抗能否作为检测经络循行路线的一个客观指标

是多年来人们一直在研究的一个问题。虽然国内外都已做了不少的工作

但意见仍然比较分歧。其中一个原因

就是对测试方法还缺乏充分的论证。针对目前皮肤阻抗研究工作中存在的问题

1987年

我们曾对测试方法作了一些重要的According to the requirement of channel rerearch

a system for rhe measur- ement of skin impedance had deen designed and a series of experiments to check the reliability of this system had also been done. The facts demonstrated that the pressure exerted by rhe exploring electrode

the duration of switch-on as well as the number of timei of repeated measurements all showed no conspicious influences on the skin impedance. The results are stable and reliable. Moreover

the measurement and data processing are controlled by microcomputer. Thus

the method of measuremenet of skin impedance along the chanuels has been developed to a higher level. Under the conditions of our experiment

the impedance of the low skin imp- edace points (LSIPs) are about 108kΩ

which are quite low than that of the non-LSIPs around them. The difference between the two is highly significant. Both the impedance of LSIPs and non-LSIPs are stable

without marked variation. These results provide the prerequistics indispensable for the further observation on the feature of the distribution of LSIPs.
