Abstract: Postural stability platforms include at least one movement resistant element Fixed to a base and coupled to a plate. The plate is movable relative to the base but the movement resistant elements resist movement of the plate. Accordingly, subjects standing upon the plate are provided a degree of stability. The movement resistant elements may include springs, hydraulic cylinders, pneumatic cylinders, electromagnetic solenoids, and the like. Furthermore, in certain instances, the degree of resistance offered by a movement resistant element may be adjusted, such as by operation of a valve, so that the stability of the plate upon which the subject stands may vary depending upon the needs of the subject.
