Fig. 3

Examples of typical full hand movement trajectories for both healthy (left) and concussed (right) individuals, at start (top) and end (bottom) of the program. Trajectories begin at the central target (red dots) and move towards one of four peripheral targets, where each green line represents a single movement trajectory. Blue ellipses denote the 95% C.I. for the final end point of the finger movements (blue dots). Correct trials (green lines) are shown. Any target with less than 5 trajectories indicates error trials (not shown). Ballistic measures are taken from initial slowing point (“ballistic movement point”, < 10% peak velocity)
