Recently, the Dynavision™ D2 Visuomotor Training Device (D2) has emerged as a tool in the assessment of reaction time (RT); however, information regarding the reliability of the D2 have been limited, and to date, reliability data have been limited to non-generalizable samples. Therefore, the purpose of this study was to establish intraclass correlation coefficients (ICC 2, 1) for the D2 that are generalizable across a population of recreationally active young adults. Forty-two recreationally active men and women (age: 23.41±4.84 years; height: 1.72±0.11 m; mass: 76.62±18.26 Kg) completed 6 trials for three RT tasks of increasing complexity. Each trial was separated by at least 48-hours. A repeated measures ANOVA was used to detect differences in performance across the six trials. Intraclass correlation coefficients (ICC 2, 1) standard error of measurement (SEM), and minimal differences (MD) were used to …
