Estimation of Respiration Variability by Heart Rate Time Series
Respiratory sinus arrhythmia (RSA) heart rate variability wavelet transform
2009/6/9
The heart rate time series contains two main rhythms : RSA (respiratory sinus arrhythmia), which is synchronous with the respiration rate, and the Mayer wave, which is generally centered around 0.1 Hz...

Quantitative Assessment System for Gait of the Elderly Using a Portable Acceleration Monitor Device
elderly people gait quantitative assessment acceleration
2009/6/9
In this study, a handy gait assessment system with a tri-axial accelerometer has been developed and its application for quantitatively assessing the gait of elderly people was examined. This assessmen...
Development of a Quantitative Measurement Method for the Magnitude of Pain Using Painless Electrical Stimulation and Its Evaluation Using Experimental Pain
pain measurement quantitative measurement pain ratio visual analog scale
2009/6/9
We have developed a method and a system to quantitatively evaluate human pain without relying on subjective criteria. The concept of pain quantification is to compare the magnitude of the subject's pa...
Fundamental Study of a Non-contact Measurement of the Viscoelastic Property of the Body Surface Tissue
non-contact measurement viscoelastic property elastic modulus coefficient of viscosity
2009/6/9
In this study, we investigate the fundamental validity of this system. This method employs compressed air pressure to apply pressure to an area (6 mm in diameter) on the body surface. The deformation...
Noninvasive Measurement of Hemoglobin Concentration Using the Near-infrared Spectroscopic Imaging Method
hemoglobin concentration near-infrared light spectroscopy noninvasive measurement
2009/6/9
We have developed a new noninvasive method for measuring hemoglobin concentration called the “near-infrared spectroscopic imaging method.” This method is based on Lambert-Beer's law and on estimating ...

Development of a Miniaturized Fiber-optic Laser Doppler Velocimetry Sensor for Local Blood Velocity Measurement—Measurement of Velocity Profile of Pulsatile Blood Flow in Model Vessel—
fiber-optic LDV sensor pulsatile flow opaque fluid local velocity measurement flow
2009/6/8
In order to measure local velocity in a pulsatile flow, the optical system and the curvature of the fiber sensor tip were improved. The fiber sensor was inserted at an insertion angle of 120 deg. thr...
Measurement of Postural Responses in Horizontal Perturbation Using Angular Velocity
Horizontal perturbation Fall Angular velocity Balance
2009/6/8
The decline of the balance function induces the elderly people to fall and it causes the decrease of daily activity to become bedridden or fear of falling. The fall occurs when sudden external forces ...
