Visual-motor integration functioning in children with Tourette syndrome.
A neuropsychological model of visual-motor integration skill was proposed and tested in 50 children with Tourette syndrome (TS) and 23 unaffected control children matched for age. Children with TS performed significantly worse than control children on the Beery Visual-Motor Integration (VMI) Test. Consistent with the proposed model, visuoperceptual and fine-motor coordination subprocesses were significant predictors of VMI scores. However, the subprocesses did not fully account for the diagnostic group difference on the VMI. These results suggest that the integration of visual inputs and organized motor output is a specific area of neuropsychological weakness among individuals with TS.
