Abstract

Learned ballistic movements display considerable variability. Far from being an artifact, this variability is an essential part of the response and provides a measure of central control of muscle activity and cerebellar integrity. We used accelerometry to measure the variability of arm rotations occasioned by step shifts in the position of a visual display. Parametric analysis of responses from 10 control subjects and 10 patients with known cerebellar deficits showed that the patients had a significant prolongation of the initial acceleration phase and a marked increase in response variability. The technique provides a tool for evaluating the outcome of therapy and studying the timing and force of rapid movements.
