Correlation between ImPACT reaction time and CRTT efficiency score in concussed athletes

The management of sports related concussion is dependent upon a standardized assessment. Reaction time is the most sensitive measure of a concussion when using the ImPACT battery, which was standardized on concussed athletes. However, an athlete’s auditory comprehension is rarely assessed systematically. Auditory comprehension status is important in properly managing concussed athletes. The Computerized Revised Token Test (CRTT) measures efficiency time. The purpose of this investigation was to determine the correlation between the ImPACT reaction time and the CRTT-Subtest VIII efficiency score in 51 concussed athletes. These two measures are statistically significantly correlated. Clinical implications are discussed
