Impact response of the standing subject — a feasibility study

Abstract

The feasibility of a pendulum impact method to establish the dynamic response of the standing subject was explored. Threaded k-wires were placed in the L 3 lumbar spinous process and in the posterior superior iliac spine. The gain and phase angle between the platform and the vertebra were established. The lower extremities were found to be very important in the attenuation of the impulse, while different shoes had little ability to attenuate the resonance peak.
