The purpose of this presentation is two-fold: 1) to examine emerging evidence from a new meta-analysis comprising 37 studies on computerized neurocognitive testing (NCT) and moderating factors, and 2) present and analyze preliminary data for 100 athletes with concussion using a newly developed vestibular ocular examination. During the past decade, the use of computerized NCT as one tool in a comprehensive assessment and management approach to concussion has become more common (Johnson et al., 2011; McCrory et al., 2009). Recently, the reliability and validity of computerized NCTs for use in assessing and managing concussion have been questioned in several review papers (Randolph, 2011; Mayers & Redick, 2012). However, as Schatz and colleagues (2012) pointed out, these reviews employed subjective research methodology involving selective inclusion of data. As such, a more objective examination of the efficacy of computerized NCT to identify the subtle effects of concussion using meta-analytic techniques is warranted. Therefore, in the current presentation, we will examine the results of a new meta-analysis to determine the effects of concussion as measured by current computerized NCTs across 37 research studies. In addition, we will examine the effects of moderators including NCT type, sport, and age. As mentioned above and in the first presentation, the assessment of sport-related concussion should be both individualized and comprehensive. One emerging area of assessment that appears to be related to concussion outcomes is vestibular ocular impairment (Chamelian et al. 2004; Paniak et al. 2004). We have developed and implemented a brief clinical examination involving vestibular ocular components including visual smooth pursuits, gaze stability, convergence, and visual-vestibular fixation. In this section of the presentation we will focus on preliminary empirical data describing vestibular ocular impairment following concussion and its role in assessment and management, as well as its relation to concussion outcomes and recovery.
