Fig. 1 Individual and composite scores for dynamics posturography sensory organization tasks (SOT). The lower scores on subjects with TBI indicate that they had poorer balance than the control subjects. These differences were statistically significant for gait condition 4 and the composite SOT score (p=0.04).

Fig. 2 Gait characteristics of patients with TBI compared to control subjects. (a) Temporal distance factors demonstrated that the subjects with TBI walked at a significantly slower speed with shorter stride length than control. The subjects with TBI had greater stride width than the controls. (b) COM movement: subjects with TBI had less displacement and a slower velocity in the anterior direction but a greater medial/lateral sway and higher velocity. There is no significant difference of motion in the vertical direction. (c) The subjects with TBI had a significantly greater medial/lateral imbalance. Asterisk indicates significance at p≤0.05.
