Do concussion related deficits in reaction time inform return to activity?
Numerous studies report deficits in reaction time following a concussion, including published research using Neurolign Dx platform devices [1,2].
The recovery time course of reaction time deficits was recently reviewed in “Examination of Reaction Time Deficits Following Concussion: A Systematic Review and Meta-analysis” , summarizing data from 60 studies totalling 9688 subjects. Results show a decline in reaction time in the immediate post-concussion period (0-3 days) with continuing slowed reaction time 21-59 days post-concussion. Reaction time deficits resolved or improved within 80-365 days post-concussion.
Growing scientific research highlights the value of reaction time for evaluating concussion and informing return to activity and or play decisions. The Neurolign Dx 100™ includes reaction time testing including auditory, visual and dual-task reaction time within their Brain Health Assessment.
