Experimental investigation on relationship between static postures and blood flow characteristics

Blood flow characteristics are collected according to the principle of Doppler ultrasonic measurement and analyzed statistically to conclude the rule of blood flow in different postures. The experiments indicate that the blood flowrate crests near the natural point, when people deviate from the natural point, blood flowrate reduces, and the more greatly people deviate from it, the less blood flowrate is. As one of the ergonomic evaluations, this investigation enables to identify the comfort range and the optimum position to guide the equipment design.
