Abstract: Objectives:To evaluate processing speed performance in outpatients with moderate-to-severe traumatic brain injury (TBI). Design:Prospective cross-sectional observational study. Participants:Twenty outpatients with traumatic brain injury (TBI) were compared with 20 matched healthy subjects. Measure:Measurement by six instruments in the domains of simple reaction time (SRT), movement time (MT), and mental processing speed at a single time occasion. Results:Significant differences were found in speed but not accuracy of work between outpatients with TBI and healthy subjects. Simple reaction time was sensitive to predicting patients with moderate-to-severe TBI as opposed to healthy counterparts. Conclusion:Outpatient clinics should consider measuring SRT.
Keywords: Traumatic brain injury, simple reaction time, movement time, mental processing speed
