Abstract

Objectives: This exploratory trial evaluated the possibility of quantitatively measuring several aspects during the “abdominal examination” of traditional Korean medicine. The main results of this study will be used to develop a new diagnostic device for abdominal examinations. Methods: Fifteen healthy volunteers were recruited for this study. Three certified Korean medical doctors assessed the existence of pressure pain, the elasticity of the abdominal muscle, and the tonus at CV12 as gold standards. Then, 2 well-trained investigators measured the pressure pain threshold (PPT), the indentation depth of a bar, and repelling force by pressing CV12. Each investigator measured the above 3 variables 2 times at 1 min intervals using a modified digital algometer. Reliability and validity tests of the 3 variables were performed. Results: There were statistically significant coefficients of intraclass correlation on the 3 variables both between and within the investigators (P<0.001). Also, PPT and repelling force showed statistically significant high sensitivity and specificity in a ROC curve. However, the indentation depth of the bar presented relatively low sensitivity. Conclusions: This new diagnostic method using a modified digital algometer could be a useful tool for quantitative measurement in “abdominal examinations”. However, future rigorous clinical studies with a large population will be needed for the verification of its usefulness.
