Experimental studies on static postural balance using the body center of gravity test system

Balance function is an assurance that people can complete the daily activities, so people have dedicated to the study of the balance function. Balancer is widely used to detect human balance function, but the equipment and the costs of the test are too expensive and not suitable for widespread generalization. Based on the previous researches about balancer, this paper proposes to develop a body center of gravity (COG) testing system. The system consists of a testing platform, a data collection system, a data processing system, a computer, a monitoring device and analysis software of the center of pressure (COP). The testing system can test the balancing indications of people in static posture balance by which people can evaluate their static balancing ability. This system can be widely applied to detect posture balance on account of its low cost and small size.
