In this paper, we present the development of a new training system for equilibrium sense and postural control. This system consists of an unstable platform, a force plate, a computer, and training programs. The unstable platform provides 360 degrees of movement allowing for training in all directions. To evaluate the effects of the training system, weperformedvariousexperimentstotraintheabilityofequilibrium sense and postural control of fifteen young healthy subjects. We measured the time a subject maintains his or hercenterofpressure on atarget, the time a subject moves his or her center of pressure to a target, and the mean absolute deviation of thetracebefore and after the training. We analyzed these parameters obtained before and after the training using paried-sample T-test. The result shows that the subjects experienced distinctive enhancement in their ability of postural control through the training using oursystem.
