ABSTRACT:
A dynamic system adapted to test a patient to determine the degree to which his physical stability is impaired and therefore predisposes the patient to injurious falls. The system includes a stable platform yielding signals that depend on the magnitude and direction of the force applied to the face of the platform. The platform is rendered unsteady by a convex rocker dish resting on the the platform face and having a flat top on which the patient stands. The resultant signals which are a function of the changing orientation of the flat top of the dish relative to the platform face are fed to a computer whose output is applied to a video monitor having a display screen on which is presented a cursor whose position is controlled by the signals. The standing patient, while viewing the screen, is required to so shift his weight on the rocker dish as to alter the orientation of the flat top to produce signals causing the cursor to travel from the center of the screen toward a computer-generated target presented on one corner of the screen, and to then acquire the target. The computer measures and scores the time it takes for the patient to cause the cursor to acquire the target as well as other variables that reflect the relative instability of the patient. These scores, taken together, define a stability index useful in deciding how then to treat the patient to improve his condition.
