Objective The startle reflex elicits involuntary release of planned movements (startReact). task-inappropriate flexor activity causing poor elbow extension movement and target acquisition. Results Task-inappropriate flexor activity increased with impairment resulting in larger flexion deflections away from the subjects’ intended target corresponding to decreased target acquisition. Conclusions We conclude that this task-inappropriate flexor activity likely results… Continue reading Objective The startle reflex elicits involuntary release of planned movements (startReact).
