This study develops devices to measure the balance maintenance ability of human against falls in sitting and standing positions. The devices are composed of parallel wire-driven mechanisms. The mechanism supports human body by its output part and leads human body to the specified direction of tilt. Furthermore, the mechanism can hold the body when the fall occurs. Thus the devices can measure the fall behavior of human reproducibility and safely. The study measured the center of pressure, tilt angle and so on of human at a fall by the developed devices and confirmed the obtained data can denote the individual differences, features about the tilt direction and so on.
