The use of vibro-tactile arrays to inform pilots about orientation (Rupert, 2000) has prompted investigations of their use in providing patients with supplementary information which may aid balancing (Wall et al. 2003). Published studies have used steady-state balancing which does not reveal whether vibration feedback can be fast enough to cue a saving reaction. Accordingly, we evaluated vibratory feedback in cueing a single step balancing response to a transient perturbation. Human subjects stood facing longitudinally on a moving walkway. Body movements were transduced with gyroscopes (angular velocity), accelerometers and Fastrak
