Abstract:
Down syndrome, also known as trisomy 21, is the most common genetic condition caused by an aberration of chromosome 21. This genetic condition can manifest in three different forms: homogenous, mosaic, and translocation. Individuals with T21 may suffer from disorders such as visuo-motor deficits that can affect their motor skills in general, particularly their fine motor skills. In our research, we conducted a descriptive study of three boys with T21 aged 8 to 10 years old at the psychopedagogical center of Akbou, to evaluate their visuo- motor abilities using an interview guide and a standardized test (the L2MA battery visuo-motor test). The results of the test showed that the alteration of visuo-motor abilities described by the L2MA was not total but rather partial. The results of our research highlighted the importance of the alteration of the product proportion capacity in children with T21
