Perceptuomotor functioning in preschool children with symptoms of attention deficit hyperactivity disorder

Given limited research on perceptual-motor functioning of preschool children with symptoms of ADHD, the purpose of this study was to compare the fine motor, gross motor, visuomotor, and oral-motor functioning of 49 4- to 6-yr.-old children with symptoms of Attention Deficit Hyperactivity Disorder and 48 typically developing children. Analysis showed scores of the ADHD group were significantly lower than those of the control group on all perceptuomotor measures. In addition, scores on all measures yielded significant correlations with scores on the Hyperactive-Inattentive scale of the Preschool Behavior Questionnaire. Regression analyses indicated that the scores of gross motor and visuomotor functioning were significant predictors of group classification (with and without ADHD). These findings extend the well documented findings of perceptuomotor deficits among school-age children with ADHD into the preschool period and emphasize the importance of early assessment and treatment of these deficits in young children with symptoms of ADHD.
