Abstract Purpose To explore the relationship between reaction time (RT) on a commonly used post-concussion computerized neurocognitive assessment and dynamic RT during sport-like movements, with and without a cognitive task. Methods Fourteen healthy individuals (7 females; age=22.3±2.5yrs, height=169.1±14.0cm, mass=71.1±16.8kg) completed a computerized Stroop task (CNS Vital Signs), where the individual presses the space bar when the color of the word does not match the word, and two dynamic RT tasks (jump landing [4 trials], anticipated cutting [8 trials]). Dynamic RT tasks were performed with (dual-task) and without (single-task) a cognitive task (subtracting by 6’s or 7’s). Participants jumped off of a 30cm box and then either performed a maximum vertical jump landing or an anticipated cut at 45. Dynamic RT, recorded using high-speed 3D-motion capture (Qualisys), was the average time (seconds) between visual stimulus and when participants’ sacrum moved >3cm in the sagittal or transverse plane. Pearson correlation coefficients (α=0.05) were calculated between all RT measures. Results Stroop RT (0.67±0.01s) was not significantly correlated with jump landing single-task (p=0.45; r=0.22), jump landing dual-task (p=0.10; r=0.45), anticipated cutting single-task (p=0.7; r=0.11), or anticipated cutting dual-task (p=0.85; r=0.06) RTs. We found positive correlations between all single- and dual-task dynamic RTs (p=.03, r=.56). Conclusion Stroop RT was not correlated with dynamic RTs, which may more closely reflect RT associated with sport participation. Commonly used computerized RT assessments may not fully represent the dynamic RT athletes need in sport tasks. Further investigation is warranted in order to develop the most appropriate RT assessments for post-concussion return-to-play.
