Postural stability testing device for use in sports field, has platforms with measurement system to measure relative position and direction of two feet attached, such that person can distribute force at real position of feet at ground

摘要

The device has two spring shackle platforms, each of which is composed of a frame (1) attached with a rigid plate (2) through force sensors (3) in order to provide a place and center intensity of forces exerted by the foot on the plate. The platforms are connected with a measurement system to measure the relative position and direction of two objects e.g. feet, attached with the platform, such that the person can distribute the force or the pressure at the real position of feet at ground.
