A balancemeter with a visual output consists of two force platform was used to evaluate body weight distribution in healthy subjects. The purpose of this study is to find a any relation between distributed partial body weight and measured graded weight bearing using balancemeter. Balancemeter is composed of force plate, multiplexer circuit, A/D conveter, and IBM PC. Force plate contains an array of 20 force sensing resisters for each foot, and produces the out put according to the force applied to the sensors. Twenty volunteers between the age of 23 and 35 participated. The data of graded weight bearing on each leg were measured while 50%, 60%, 70%, 80%, 90% and 100% of their body weight was distributed to the each leg on the balancemeter. The result shows a significant relation between asked percent of body weight and measured graded weight bearing on the balancemeter(left: r=0.96, p<0.01, right: r=0.92, p<0.01).
