Motor Function of Autistic Children: What Type of Control?

Abstract

Labiadh L, Landolsi M and Ramanantsoa MM

Henceforward, autism is considered as a neurodevelopmental disorder characterized by a deficit of language and communication both associated with a restricted repertoire of activities, motor actions and interests. The aim of the current work was to investigate into a comparative study between standard and autistic children the production of successive linked motor actions. We predicted that the autistic children as the standard ones succeeded to perform the basic motor actions like walking, catching, jumping or running. For example, all the children succeeded to throw the scarf (75%), even if the autistic children sometimes interrupted the execution of this task by stereotyped and repetitive movements (23%). A pragmatic control handled their performances. However, we also advanced a deficit of more cognitive levels in performing those motor actions in planning plan because they required a semantic control. For example, to place the circle in the marks drawn in the ground, the autistic children performed this task in (8 s ± 13.2 s) contrary to the standard ones (0.5 s ± 1 s).
