<abstract displayLabel="Summary">The ballistic movement is defined as a rapid voluntary movement which is motor programmed and in which visual feedback for path correction is not possible. A discrete ballistic movement is of short movement duration with a triphasic pattern in the elctromyograph (EMG) for muscle activity and has an acceleration pattern which approximates a sinusoidal wave form. The aim of the present work was to fully explore the geometrical factors which determine whether a movement will be made ballistically or under visual control</abstract>
