Resumen de Dual Motor Task Coordination in Children With and Without Learning Disabilities
Jill Whitall, Susan McMenamin, Nancy Getchell
This study examines gross motor coordination in children with and without learning disabilities using a dynamical systems perspective. In a dual motor task paradigm (walk/clap, gallop/clap), we measured and compared frequency and phase locking and consistency within and across trials in 12 children with learning disabilities and 12 age-matched typically developing children. In the walk/clap condition, groups differed in consistency and in entrainment (increased frequency of 4 limb coupling) over short-term practice. In the gallop/clap condition, groups differed in consistency; neither group showed entrainment. Comparisons within the LD group of participants with and without diagnosed visual-motor problems showed differences in classification, consistency, and entrainment. These results suggest that gross motor coordination tasks provide information about as well as a novel opportunity for early identification of learning disabilities
