(A) The main sequence for peak constriction velocity (top), and average constriction velocity (bottom), under the optimal test stimulus condition (bright red step), (B) the main sequence for peak dilation velocity (top) and average dilation velocity (bottom), under the optimal test stimulus condition (bright red step). The solid line represents the normal group, and the broken line represents the mTBI group. All four velocity parameters were significantly different (p < 0.05) under this condition, being slower in the mTBI group.
Avg CV: Average constriction velocity; Avg DV: Average dilation velocity; CV: Constriction velocity; DV: Dilation velocity; mTBI: Mild traumatic brain injury.
