Abstract EN
An accurate assessment of the pulse depth in pulse diagnosis is vital to determine the floating and sunken pulse qualities (PQs), which are two of the four most basic PQs.
In this work, we proposed a novel model of assessing the pulse depth based on sensor displacement (SD) normal to the skin surface and compared this model with two previous models which assessed the pulse depth using contact pressure (CP).
In contrast to conventional stepwise CP variation tonometry, we applied a continuously evolving tonometric mechanism at a constant velocity and defined the pulse depth index as the optimal SD where the largest pulse amplitude was observed.
By calculating the pulse depth index for 18 volunteers, we showed that the pulse was deepest at Cheok (significance level: P<0.01), while no significant difference was found between Chon and Gwan.
In contrast, the two CP-based models estimated that the pulse was shallowest at Gwan (P<0.05).
For the repeated measures, the new SD-based model showed a smaller coefficient of variation (CV≈7.6%) than the two CP-based models (CV≈13.5% and 12.3%, resp.).
The SD-based pulse depth assessment is not sensitive to the complex geometry around the palpation locations and temperature variation of contact sensors, which allows cost-effective sensor technology.
