Προτίμηση χεριού και περιστροφική συμπεριφορά δεξιόχειρων και μη-δεξιόχειρων παιδιών με τυπική ανάπτυξη και νευροαναπτυξιακές διαταραχές

Abstract

Rotational motion is along with hand, foot, eye and ear pleading, cerebral asymmetry markers, or pleating markers. Any dysfunction in the basal ganglia may cause damage to motion inhibition, which is manifested by either repetitive movements or stereotypes. Rotation movement has been extensively studied in animals and in normal population, adults and children. Rotational behavior and its relationship to hand flanking has been studied less in children of typical development, particularly in children with neurodevelopmental disorders that belong to either the Spectrum of Autistic Disorders or have Mental Disability or Down Syndrome. The aim of this study was to investigate the rotational behavior of right and non-right children with neurodevelopmental disorders and to compare it with the rotational movement of typical children in a specially shaped environment by participating in hand and performance tests in four Rotary works. The comparisons between the two groups and between the subgroups were based on the cognitive rather than the chronological age of the children. The findings have highlighted a left-handed trend in children with neurodevelopmental disorders, relative to typical developmental children, a tendency that can be attributed to biological, social or environmental factors.
