Abstract:
The purpose of this study was to examine the validity of ImPACT, a computerized neuropsychological test battery, for measuring attention and processing speed in athletes with concussions. This was accomplished by comparing the computerized testing to a traditional neuropsychological measure, the Symbol Digit Modalities Test. Participants were 72 amateur athletes who were seen within 21 days of sustaining a sports-related concussion. As predicted, the SDMT correlated most highly with the Processing Speed and Reaction Time composites from ImPACT.
The Value Added of Neurocognitive Testing After Sports-Related Concussion

Abstract:
Neurocogntive testing has been endorsed as a 'cornerstone' of concussion management by recent Vienna and Prague meetings of the Concussion In Sport Group. Neurocognitive testing is important given the potential unreliability of athlete self-report after injury. Relying only on athletes' reports of symptoms may result in premature return of athletes to contact sport, potentially exposing them to additional injury.

Abstract:
Normative Data for the ImPACT Composite Scores
A sample of 205 elementary, junior high, and high school students was initially used for this project. Three of these subjects had incomplete test data and were subsequently dropped from the normative sample. The current normative sample consists of 102 boys and 100 girls between the ages of 11 and 14. Multiple analysis of variance (MANOVA) was performed to allow an analysis of performance differences between gender and age across multiple neuropsychological domains.

Abstract:
Neuropsychological testing is a variable tool in concussion diagnosis and management. ImPACT, a computerized neuropsychological testing program, consists of eight cognitive tasks and a 21-item symptom inventory. ImPACT was used to examine the cognitive performance of 104 concussed athletes at baseline, 2, 7, and 14 days post-injury. Dependent measures included composite scores from the ImPACT computerized test battery, as well as a total symptom score from the Post-Concussion Symptom Scale.
