Abstract
As one of four diagnosis methods (looking, listening, questioning, and touching) in Chinese medicine, pulse diagnosis (one of the touching methods) occupies an important position. However, different schools of Chinese medicine have different views on how to get and to distinguish the pulse. These views about the pulse have been handed down by as qualitative expressions derived from long experience. These expressions cannot be immediately and widely applied to diagnosis without enough experience. In this study to standardize pulse diagnosis, the pulse of several subjects was measured near the wrist joint of their left radius bone using a condenser microphone with various depression pressures, and change of pulse wave images was examined. A strong relationship was found between the change of pulse image and the depression pressure.
