Test-retest reliability of the BrainFx 360 performance assessment

Abstract

Concussions occur at a frequency between 1.6 and 3.8 million injuries per year. Concussion assessment tests have been designed to compare post injury performance with preseason baseline performance. However to date, there is not a gold standard in concussion assessment testing. Many assessment tests lack acceptable reliability. The purpose of this study was to examine the test-retest reliability of the BrainFx 360 Performance Assessment. Fifteen healthy adults recruited from a large university in the south participated in this study. Participants took the initial assessment and returned seven to fourteen days later for the retest. The overall performance of BrainFx had good reliability. The results of most categories and subsections display moderate to acceptable reliability. Some subtests showed extremely low reliability and should be altered or thrown out in order to increase the overall reliability of performance. Future studies should consider using a randomized test order to assess the test-retest reliability.
