Overview
Brief Summary
Although some important progresses were made in the field of the meridian research, no breakthroughs have been achieved. Besides,there are some problems in meridian researches. Particularly, previous research of meridian phenomenon involved lots of subjective elements and outcomes.Researches that use modern scientific techniques to investigate the biological characteristics of meridian phenomenon are urgently needed. Therefore, this study is designed to assess the heat transport characteristics of meridian phenomenon for the Heart and Lung meridians by using infrared thermal imaging. Thus, the biological characteristics of meridian phenomenon could be presented objectively in a scientific methodology.
Detailed Description
This study will include 40 patients diagnosed with chronic stable angina pectoris (CSAP) and 40 healthy volunteers. Infrared thermal imaging will be adopted to assess the heat transport characteristics of meridian phenomenon for Heart and Lung meridians in the physiology/pathological state. In addition, by comparing the heat transport characteristics in the acupoints along the Heart and Lung meridians, the relative specificity of the two meridians will also be investigated. Primary outcomes will be infrared thermal images and acupoint temperature. Furthermore, this study will build standardized techniques and schemes for detecting the heat transport characteristics of meridian phenomenon for Heart and Lung. The results of this study could also provide scientific foundation for traditional meridian theories.
