N2  - Background: Mild traumatic brain injury is a common neurological condition affecting adolescents in North America. In adults, symptoms related to balance are some of the most commonly reported.  Methods    The purpose of this study was to investigate the balance in adolescents with mild traumatic brain injury using linear and non-linear centre of pressure (COP) measures in quiet stance and during dual-task. Adolescents aged 13.00 to 17.99 years were tested once at one month following mild traumatic brain injury (n = 25), and healthy adolescents (n = 22) were tested once as controls in four conditions: standing with eyes open, standing with eyes closed, standing on a single leg and standing while performing a visual Stroop task.    RESULTS:    In general, compared to healthy adolescents, adolescents with mild traumatic brain injury demonstrated more variability (p = 0.007, 95% CI (0.9, 5.4) and p = 0.049, 95% CI (0.009, 4.0), mediolateral and anteroposterior, respectively), showed more cumulative movement (path length, p = 0.016, 95% CI (1.3, 11.9)) and required greater speed of movement (p = 0.012, 95% CI (0.99, 7.4) and p = 0.035, 95% CI (0.28, 7.5), mediolateral and anteroposterior, respectively) in maintaining balance, and in underlying temporal organization showed less local stability (mediolateral largest Lyapunov, p = 0.033, 95% CI (0.001, 0.027)), more short-term complexity anteroposteriorly (p = 0.029, 95% CI (0.005, 0.099)) and less long-term complexity mediolaterally (p = 0.001, 95% CI (0.015, 0.056)). Condition differences are additionally presented.<br><br>CONCLUSIONS: Findings suggest that, for adolescents with mild traumatic brain injury, when maintaining balance visual input is relied on differently, the effectiveness of control may be an issue during dual-task, and consequently, the challenge of dual-task may be on par with single leg stance.<p />  <p>Language: en</p>
