| Research Abstract |
The purpose of this study was to develop a health index using the chaos analysis and the simple and easy device that it was in response dynamics of the microcirculation when we pressurized a finger-tip progressively using finger tip plethysmograph. As a result, the wave form change of the pulse wave that was obtained by pressurizing a finger-tip progressively included information different from blood pressure and the pulse that were existing technique, the fluctuation analysis results of heart autonomic nerve. Furthermore, by analysis of the non-linear time-series data, we were able to catch a characteristic of the vital reaction associated with the circadian rhythm. This study suggested that the measurement technique that we developed could be in use as a tool for simple and easy health care.
