The purpose of this study was to examine the recovery of gait stability following concussion under conditions of undivided (single-task) and divided (dual-task) attention over the course of 28 days. Subjects who sustained a concussion (CONC) and matched uninjured controls (NORM) were observed while walking and while concurrently completing simple mental tasks. The CONCs were assessed within 48 hours of injury and again at 5, 14, and 28 days post injury. The NORMS were evaluated at the same time intervals. Whole-body motion data were collected to examine displacement and velocity of the center of mass (COM), and the maximum separation between the COM and center of pressure (COP). CONCs were found to walk significantly slower and with a greater separation between the COM and COP during dual-task on all testing days when compared to the controls. The CONCs were also found to have greater sway and sway velocity than NORMS when attention was divided. The findings of these studies suggest that concussion may have long-term measurable effects on the control of gait stability.

520 $a The purpose of this study was to examine the recovery of gait stability following concussion under conditions of undivided (single-task) and divided (dual-task) attention over the course of 28 days. Subjects who sustained a concussion (CONC) and matched uninjured controls (NORM) were observed while walking and while concurrently completing simple mental tasks. The CONCs were assessed within 48 hours of injury and again at 5, 14, and 28 days post injury. The NORMS were evaluated at the same time intervals. Whole-body motion data were collected to examine displacement and velocity of the center of mass (COM), and the maximum separation between the COM and center of pressure (COP). CONCs were found to walk significantly slower and with a greater separation between the COM and COP during dual-task on all testing days when compared to the controls. The CONCs were also found to have greater sway and sway velocity than NORMS when attention was divided. The findings of these studies suggest that concussion may have long-term measurable effects on the control of gait stability.
520 $a Group differences in the recovery of athletes and non-athletes were also examined. The athletes whether concussed or not, displayed significantly greater sway and faster sway velocity than non-athletes. In order to evaluate whether repeated subconcussive blows may have contributed to deficits in gait stability, athletes were recategorized into those sustaining high and low velocity blows during their chosen sport. The low velocity group showed greater sway than the high velocity group during dual-tasking. This finding suggests that repeated sub-concussive blows may result in a measurable consequence for controlling gait stability.
520 $a A final study examined the relationship between measures of gait stability and neuropsychological function including reaction time, memory, and visual-motor processing speed following concussion over the course of 28 days. The results revealed little association between measures of cognitive function and gait stability. Post-concussion cognitive and motor recovery curves are each unique with NP measures resolving between 5 and 14 days while gait variables continue to be significantly altered at 28 days post-injury. This dissertation includes both my previously published and coauthored materials.
