An objective method of pulse diagnosis.

One component of Oriental medical diagnosis is pulse diagnosis. To make this method more objective, three pressure transducers were positioned over the radial artery and the absolute pressure of 50, 100 and 150 g was applied at three positions to simulate the classical pulse diagnosis. The transient pressure changes at the same absolute pressure were recorded. The pressure changes at the three positions were not equal even when the same absolute pressure was applied. Pressures were compared in superficial and deep locations, right and left wrist. The largest deflection was considered as excess and the smallest as depletion in twelve meridians.
