The overall number of Emergency Departments (ED) visits from 2006 to 2010 reportedly increased by 3.6%, during which time visits for Traumatic Brain Injury (TBI) increased by 29.1% [1]. This sharp in-crease reflects heightened awareness about TBI, which is expected to drive this number even higher in the future [1]. Further, 95% of all head-injured patients who visit the ED present with mild symptoms [2].

Currently, Computerized Tomography (CT) is the accepted gold standard for identifying acute intracranial injuries in the ED. Although the vast majority of head injured patients receive a CT scan, over 90%are found to be CT negative [3,4]. Standard clinical practice in the ED does not include assessment of functional brain injury or concussion in patients found to be CT−.Early identification of mild TBI/concussion is associated with lower risk of re-injury, reduced morbidity and im-proved outcomes [5]. The identification of mTBI/concussed patients and their ED discharge referrals could be greatly aided by accurate, objective, quantitative information about brain function status [6].
