Abstract
Complex and dual-task gait performance is altered following a concussion. Gait termination is one method of assessing complex gait performance. The purpose of our study was to determine how planned and unplanned gait termination with and without a cognitive load affected gait performance outcomes in individuals with and without a history of concussion. Physically active college-aged adults performed a series of planned and unplanned gait termination walking tasks on a Zeno Walkway, with and without serial subtraction (by 7s). We found that there were no differences in the dual-task cost of cognitive and gait performance outcomes between those with and without a history of concussion, suggesting that impairments in gait performance after concussion may resolve over time. Future research should assess the timeline of this potential recovery and evaluate complex and dual-task gait performance using novel methods.
