Abstract: Context: Dual-Task testing, which requires a person to perform both a cognitive and physical task simultaneously, has been suggested as an additional concussion assessment tool. Previous Dual-Task research has focused on various laboratory based tests and has not yet reached a consensus on a Dual-Task combination that can be utilized in the clinical setting for assessing sport-related concussions. Design: A randomized repeated-measure design. Objective: To develop Dual-Task tests using clinically practical physical and cognitive tasks. The effect of Dual-Task tests was investigated by comparing the outcome measures to that of Single-Task tests on healthy subjects. Method: 54 healthy participants were recruited. Testing involved one physical task and three cognitive tasks. Repeated Measure Analysis of Variance (ANOVA) and paired t-tests were performed on SPSS v22.0 with an alpha level of p<0.05. Intraclass Correlation Coefficient (ICC 2,1) was used to analyze test-retest reliability between sessions. Interventions: Testing involved one physical task [Expanded Timed Get-Up-and-Go (ETGUG)] and three cognitive tasks [Backward Digit Recall (BDR), Serial Sevens (SS), and Auditory Pure Switch Task (APST)]. Participants performed all tasks as Single-Task and all combinations of physical and cognitive tasks as Dual-Task in randomized order, with the same investigator recording each score. Main Outcome Measures: Time to completion for the ETGUG was recorded and Error, Digit Span, Accuracy, and Response Rate were recorded for each cognitive task were compared between Single-and Dual-Task testing conditions. Results: Repeated Measure ANOVA indicated that ETGUG time to completion significantly increased when paired with any of the three cognitive tasks [(BDR: 26.013 seconds, SS: 25.734 seconds, and APST: 22.302 seconds) vs. Single-Task ETGUG: 20.082 seconds (p<0.001)]. Among the three cognitive tasks, Response Rate for SS and APST significantly decreased when paired with ETGUG (SS: p<0.01; APST: p=0.024). Test-retest reliability (ICC) for the ETGUG ranged from 0.71 to 0.94. Conclusions: The current study utilized clinically practical physical and cognitive tests to develop Dual-Task combinations on a healthy population. Based on the results, these Dual-Task combinations had similar effects as shown in previous research and may show promise as part of developing a practical, clinically based dual-task test for assessing concussion. Future studies should include application of these Dual-Task tests to a concussed population to investigate the efficacy of the Dual-Task tests in identifying concussion deficits.
