Measuring processing speed after traumatic brain injury in the outpatient clinic.
OBJECTIVE
To evaluate processing speed performance in outpatients with moderate-to-severe traumatic brain injury (TBI).


METHODS
Prospective cross-sectional observational study.


METHODS
Twenty outpatients with traumatic brain injury (TBI) were compared with 20 matched healthy subjects.


METHODS
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.


CONCLUSIONS
Outpatient clinics should consider measuring SRT.
