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.
