The Effect of Visual Perceptual Training on Screening for Driving Using the Useful Field of View Test Following Moderate to Severe TBI

This study focuses on people aged 19-59 sustaining moderate to severe traumatic brain injury who exhibit difficulty with visual processing speed based on Useful Field of View (UFOV) test performance. After consent these people are randomly assigned to a visuo-perceptual speed training program (Posit Science Insight) or standard treatment (35 in each group). The treatment program is performed on a computer at home with instructions to spend 30 minutes per day using the program. After 6 weeks the person is again assessed with the UFOV test and participates in a driving simulator assessment. A brief neurolopsychological assessment is also completed at study initiation and during the 6 week follow-up. The success of returning to driving (frequency, duration, safety) is assessed at regular intervals during the year following injury. The primary hypothesis is that people with TBI participating in the training program will perform better on the UFOV divided and selective attention subtests than non-treatment subjects reflecting improved visual processing speed.
