The Portable Warrior Test of Tactical Agility (POWAR-TOTAL) is a valid mTBI assessment tool which incorporates DT assessment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods<\/jats:title>\n                    <jats:p>Forty-six SM diagnosed with mTBI and 59 healthy control (HC) SM performed the POWAR-TOTAL. Group differences in relative DT effect were categorized based on performance trade-offs and prioritizations. A paired-sample t-test was performed to examine the relationship between the motor and cognitive relative DT scores for SM with mTBI and HC. Cognitive and motor performance of the mTBI group pre- and post-intervention were compared to the HCs values using an independent t-test. Average pre- and post-intervention relative DT effects were charted on a polar plot.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Although cognitive and motor performance differed between the HC and pre-intervention groups, relative DT effects (% change normalized by SM baseline performance) were not significantly different. Relative DT for the pre- and post-intervention mTBI group also were not significantly different. HC group and post-intervention group differences were non-significant, suggesting improvement in performance after therapy. Patterns of interference between the groups differed at mTBI pre-intervention, but were similar at post-intervention.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Service members prioritized motor performance over cognitive performance, with relative dual-task costs that were small and similar in both groups. Cognitive accuracy changes over multiple trials could be minimized by an improved testing protocol. Since simple single and dual-task measures of cognitive and motor performance captured significant group differences, the calculation of POWAR-TOTAL dual-task effects does not appear to provide critical information for test interpretation.<\/jats:p>\n
