Abstract

The first aim of this study was to examine qualitative motor performance and working memory (WM) in boys with ADHD and matched controls. The second aim was to explore the relationship between qualitative motor performance and WM in a sample of children with ADHD. Thirty-nine boys with ADHD, aged 7-9 years, and thirty-nine matched controls participated. Gross motor skills were assessed using the second edition of the Test for Gross Motor Development (TGMD-2). The Verbal Fluency Test (VFT) and Self Ordered Pointing Task (SOPT) were used to assess verbal WM and visuospatial WM, respectively. Children with ADHD showed significant poorer performance on object control skills and locomotor skills of the TGMD-2 compared to their peers. In addition, significant differences were found on the number of perseverations and intrusions made on the VFT. Significant moderate relationships between total score (r=-.44), object control score (r=-.40), and locomotor score (r=-.32) and total time on the SOPT were found in boys with ADHD, controlling for age and the number of errors on the SOPT. Children with ADHD had poorer qualitative motor performance than controls. A moderate relationship was found between qualitative motor performance and visuospatial WM, indicating a better performance on the SOPT when scoring better on qualitative motor performance. To improve motor skills in boys with ADHD, motor intervention is needed. This intervention might be beneficial for visuospatial WM.
