Abstract
The sensitivity to detect a perturbation at low speed and small magnitude was evaluated to determine the physiological response differences that arise with age. Seven slow speeds ranging from 1.25 - 4.3 cm/s were chosen to evaluate the postural responses (electromyograms) and postural behavior (center of pressure) while subjects stood on a platform that was perturbed anteriorly. This preliminary study indicated that the muscle activation latency is longer in the older population, though both groups show an effect of speed. A significant difference does exist between groups at the intermediate speeds, but center of pressure data showed little differences between groups in regard to the behavior of the body's movements. Future tests will include larger subject groups, neurological deficit groups, and the addition of kinematic data to evaluate joint rotations.
