“…The PEMT and other AMMP tasks were designed to challenge integrated functional performance and reveal residual deficits that become evident when limited and shareable brain resources are deliberately stressed,31 but are neither diagnostic nor mechanistic. Multiple studies32, 33,34,35,36 have shown that postconcussive dual-task deficits in gait, obstacle clearance, and balance, measured in laboratory settings, persist over much longer time frames than cognitive deficits observed in single-task conditions. This type of concurrent multiple-domain testing is intended to reveal deficits in SMs that are not always evident from single-domain assessments.…”

“…The Stoop test was used in conjunction with postural stability due to reliability and ease of testing. 4,5 If successful, the results of this study would be an important step toward utilizing these assessments in a concussed population to identify risk of lower-extremity injury following concussion.…”

“…3 The use of a dual-task assessment, which adds a cognitive load to a motor assessment, has the potential to be a more sensitive test of concussion. 4 The addition of a cognitive load may affect postural stability due to the finite amount of resources available to process loads simultaneously. 2 Postural stability is an important measure of neuromuscular control that can also identify risk for musculoskeletal injury.…”

“…Common dual-task assessments include postural stability assessments paired with a cognitive load such as the Stroop test. 3,4 The Stroop test, a visual, color-based load, has good test-retest reliability. 4 One of the first steps in the development of a tool to screen for musculoskeletal injury following concussion is to determine the reliability of the assessment in a healthy population.…”

Context: Concussions are consequence of sports participation. Recent reports indicate there is an increased risk of lower-extremity musculoskeletal injury when returning to sport after concussion suggesting that achieving “normal” balance may not fully indicate the athlete is ready for competition. The increased risk of injury may indicate the need to refine a screening tool for clearance. Objective: Assess the between-session reliability and the effects of adding a cognitive task to static and dynamic postural stability testing in a healthy population. Setting: Clinical laboratory. Participants: Twelve healthy subjects (6 women; age 22.3 [2.9] y, height 174.4 [7.5] cm, weight 70.1 [12.7] kg) participated in this study. Design: Subjects underwent static and dynamic postural stability testing with and without the addition of a cognitive task (Stroop test). Test battery was repeated 10 days later. Dynamic postural stability testing consisted of a forward jump over a hurdle with a 1-legged landing. A stability index was calculated. Static postural stability was also assessed with and without the cognitive task during single-leg balance. Variability of each ground reaction force component was averaged. Main Outcome Measures: Interclass correlation coefficients (ICC2,1) were computed to determine the reliability. Standard error of measure, mean standard error, mean detectable change, and 95% confidence interval were all calculated. Results: Mean differences between sessions were low, with the majority of variables having moderate to excellent reliability (static .583–.877, dynamic .581–.939). The addition of the dual task did not have any significant effect on reliability of the task; however, generally, the ICC values improved (eyes open .583–.770, dual task .741–.808). Conclusions: The addition of a cognitive load to postural stability assessments had moderate to excellent reliability in a healthy population. These results provide initial evidence on the feasibility of dual-task postural stability testing when examining risk of lower-extremity musculoskeletal injury following return to sport in a concussed population.
