Centre of pressure during quiet stance and dual-task one month after mild traumatic brain injury: In adolescents

BackgroundMild 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.MethodsThe 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.ResultsIn 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 =...
