Reaction and movement times in individuals with chronic traumatic brain injury with good motor recovery.
Reaction times and movement times were studied in 18 individuals with severe traumatic brain injury (TBI) and 36 matched normal controls. Reaction times depended on the type of task: in the case of simple visual stimuli (Alertness condition) they were similar in individuals with TBI and normal controls. In contrast, individuals with TBI were slower in a Go-no-go test. Regardless of task, movement times depended on movement length and were slower in individuals with TBI. These findings indicate the presence of a residual motor programming deficit in individuals with TBI even in the chronic stage and in the presence of good motor recovery, as assessed clinically.
