Ninety articles on electrical properties of acupoints and 38 closely related articles with the time raged from 1950s' till present were retrieved and studied from Pubmed, CNKI and VIP databases. Conclusions indicate that most of the low-resistance points or high potential points of the skin are in accordance with acupoints. However, not every acupoint shows the property of low-resistance or high potential feature. The electrical properties of acupoints vary with the physiological and pathological changes of the human body. And the electrical properties of acupoints which share the same name on the affected meridians located symmetrically on bilateral sides of the body were in a condition of imbalance. However, the result of measurement can be affected by the type of apparatus, intensity, size and number of the electrode etc. Therefore, the future study should be focused on the reaction laws of electrical properties of acupoints under physiological and pathological conditions through selection of different resistance measurement apparatus and strictly control of the impacting factors during the researching process.
从PubMed、CNKI和维普数据库中检索并研究了90篇关于穴位电学特性的文章以及38篇与之密切相关且时间跨度从20世纪50年代至今的文章。结论表明，皮肤的大多数低电阻点或高电位点与穴位相符。然而，并非每个穴位都表现出低电阻或高电位特征。穴位的电学特性随人体生理和病理变化而变化。并且，位于身体双侧对称位置的同名经上的穴位电学特性处于失衡状态。然而，测量结果会受到仪器类型、电极强度、大小和数量等因素的影响。因此，未来的研究应通过选择不同的电阻测量仪器并在研究过程中严格控制影响因素，重点关注穴位电学特性在生理和病理条件下的反应规律。
