ABSTRACT Introduction Neurocognitive assessment tools such as the Neurotracker and ImPACT have been proposed to optimize sports-related mild traumatic brain injury (mTBI) management. Baseline testing is recommended with such assessments to individualize monitoring of athletes' remission. While the ideal timeframe between baseline updates has been studied for the ImPACT, these data are missing for the Neurotracker. Objective The current study aimed to compare the test–retest reliability of the ImPACT and Neurotracker for two consecutive seasons in university athletes participating in sports at risk for mTBI. Methods At the start of two consecutive seasons, 30 athletes with no recent history of mTBI completed a baseline assessment including the Neurotracker and the ImPACT. The test–retest reliability of the results was analyzed by considering intra-class correlation (ICC), Becker’s standardized mean difference (dB) and Bland-Altman’ plot of each outcome. Results The Neurotracker and the Visual Motor Speed composite score of the ImPAC were the only outcomes with significative ICCs and acceptable d B between the two seasons. Neurotracker was the only outcome with a significative bias (+0.179). Conclusion Our research suggests that the Neurotracker has an acceptable level of test–retest reliability after one year in comparison to the ImPACT.
