A study of parallel wire-driven mechanisms for measuring human physical capabilities to prevent a fall

本研究开发了一套测量人体在坐姿和站姿对抗福尔斯跌倒时平衡保持能力的装置。该装置由平行的线驱动机构组成。该机构通过其输出部分支撑人体，并将人体引导至指定的倾斜方向。此外，该机构可以在跌倒发生时保持身体。因此，该装置可以重复性和安全地测量人体的跌倒行为。本研究利用所研制的装置对人体在跌倒时的压力中心、倾斜角度等进行了测量，并证实所获得的数据能够表征人体的个体差异、倾斜方向等特征。

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.
