摘　　要：为总结和分析穴位电阻研究进展和存在问题,探讨相应的解决思路,收集了1990—2011年的相关穴位电阻检测方面的文献,探讨不同检测类型仪器的优势和不足。穴位电阻的检测技术已取得一定的进展,这些技术通常用来进行腧穴定位和临床诊断,检测技术的进步主要表现在电路模型的改进,可连续检测更长时间、介质干扰更少等。但以往研究往往集中在皮肤电阻的检测,由于皮肤电阻并不等于穴位电阻,等效电路的设计不能反映穴位内部细胞、组织和神经的情况,而且检测技术也存在缺陷,主要影响因素如电极极化、接触介质和穴位解剖特点等难以排除,使得穴位电阻不能成为临床诊断标准和疗效判别的有效依据。针对上述穴位电阻研究的技术手段存在的瓶颈问题,提出需要通过修改技术方法、电路模型设计,并采用建立数学模型等使研究更加符合生命活体系统的要求,在穴位电阻研究中考虑人体的电感等,在仪器的设计中要尽量排除各种干扰因素,使实验设计能充分体现穴位内部的电阻变化规律。In order to summarize and analyze the progresses and problems of resistance testing and technology research on acupoints, investigate the related solutions, articles on resistance testing from 1990 to 2011 were col lected, and advantages and shortcomings of different types of testing instruments were discussed in this article as well. Detection technology of aeupoint impedance has under updating changes, which are often applied on locating acupoints and clinical diagnosis. The progresses of those technologies are mainly embodied in improvement of cir coil model, whicb enable a longer testing duration, less media interference and so on. The previous studies often focus on resistance testing of the skin. Since dermal resistance does not equal to acupoint resistance, the designation of equivalent circuit does not embody the condition of cells, tissues and nerves at acupoints, and lesting technology is often affected by factors such as polarization of electrodes, contact medium and anatomical characteristics of acupoints, the resistance of acupoints can not be taken as the effective framework of the diagnostic standard and judgement of therapeutic effect in clinic. Based on the key problems in resistance testing of acupoints, it is proposed by the article that the techniques and designalion of circuit model should be reformed, and mathematical model should be established in the study to meet the requirement of the life system. Inductance of human body should be considered in resistance research of acupoints, and interference factors should be eliminate as far as pos sible in designation of equipments. Thus, the change law of acupoint resistance in the inner part of the body can be fully embodied by the designation of experiments.
