The sensitivity and specificity of commonly implemented sideline assessment tools are generally good to very good , especially for symptom scores and cognitive evaluations performed within 48 hours of injury , and they are improved when a baseline evaluation is available for comparison .
CONTEXT The sideline assessment of concussion is challenging , given its variable presentations , the limited sensitivity and specificity of sideline assessment tools , and how the presentation of the injury evolves over time .
In addition , the diagnostic process , as well as the tools used to assess and manage concussion , continue to progress as research and what we know about concussion advance .
This paper focuses on the initial assessment on the sideline by review ing the concussion-evaluation literature , drawing from clinical experience to emphasize a st and ardized approach , and underscoring the importance of both familiarity with the athlete and clinical judgment .
OBJECTIVE To review the evidence regarding the clinical assessment of sport-related concussion on the sideline .
Additional considerations included making same-day return-to-play decisions , the sensitivity and specificity of sideline testing , and the importance of ongoing assessment and follow-up of injured athletes .
CONCLUSIONS The sideline assessment of sport-related concussion is challenging given the elusiveness and variability of presentation , reliance on athlete-reported symptoms , and the varying specificity and sensitivity values of sideline assessment tools .
In addition , the recognition of injury and assessment often occur in a time-pressured environment , requiring rapid disposition and decision making .
Evaluation of Neuropsychological Domain Scores and Postural Stability Following Cerebral Concussion in Sports
Context With increasing knowledge and research about concussion , there have been few objective studies that have used neuropsychological domain scores and postural stability to assess concussion . Objective To evaluate the recovery curve of athletes who incur sport-related concussion from repeated serial testing of neuropsychological and posturography testing . Design A prospect i ve epidemiological model was used for the course of the study . Setting Division I intercollegiate athletics . Participants Athletes participating in football , soccer , basketball , softball , and cheerleading . Main Outcome Measures  Neuropsychological scores and posturography measures  were obtained preseason and serially at day 1 , day 2 , day 3 , and day 10 postconcussion .  Control participants  were tested at the same intervals .  Neuropsychological scores were converted to st and ards score and then into domains of attention , learning , speed of information processing , concentration , memory , and verbal fluency . Analysis of covariance with the baseline test as the covariate was used to analyze the data with univariate post hoc tests performed . Results Significant group differences were found for self reported symptoms ( P = 0.001 ) , speed of information processing ( P = 0.005 ) , mean stability ( P = 0.002 ) , and vestibular function ( P = 0.003 ) between injured and control participants . A group , by day , planned comparison found that speed of information processing and composite balance measures demonstrated significant differences through day 10 postinjury , while symptoms and the vestibular ratio remained significant only through day 3 . Conclusions The concussion recovery curve demonstrated short-term neuropsychological and posturography deficits following injury . A comprehensive approach to concussion management should be used to assess the injury and make return-to-play decisions
