Analysis on the characteristics and interference factors of different types of measurement instruments for meridian-acupoint resistance / 中国针灸

ABSTRACT

The meridian-acupoint has response function and effect function. As a direct reflection between acupoint and diseased area, the response function is the foundation of the effect function, and skin resistance of acupoint is usually used as an objective indice for research of meridian-acupoint response. Among the skin resistance-based researches on specificity of meridian-acupoint reaction, the selection of instrument is a key point. At present the main measurement instruments for meridian-acupoint resistance include dual-electrode device and four-electrode device. After analyzing the characteristics and inter-ference factors of different types of measurement instruments for meridian-acupoint resistance, dual-electrode device is suitable for qualitative analysis, for its control of interference factors needs to improve. The four-electrode device is good at quantitative research, for it is easier to control interference factors. Yet, there is more for research department to do to improve the instrument design by modern scientific technique in order to meet need for research.
