The difficulties of defining the concepts of praxies and coordination during the development of the child are linked with recent debates and consensus-building regarding the diagnostic criteria for the developmental coordination disorder (DCD), dyspraxia, disorders of motor skills. The relevance of the proposed therapeutic approach logically depends on the clarity of the identification of disorders; in the current state of knowledge, support for children “DD” or “DCD” is still not consolidated. We report the recommendations established by certain organizations or scientific societies (Economic and Social Research Council Leeds 2006, INSERM 2007, European Academy for Childhood Disability 2012, Réseau Régional de Rééducation et Réadaptation Pédiatrique 2012, Caisse Nationale de Solidarité pour l’Autonomie 2014) as well as the therapeutic proposals published by the clinicians and researchers particularly invested in this area (Albaret, Gerard, Mazeau…). Our service at the Hôpitaux de Saint-Maurice has developed experience in the diagnostic and therapeutic support for children with developmental dyspraxia and children with praxic disorders associated with early brain damage. This leads us today, in the light of the recent work on the difficult passage of the assessment to the rehabilitation. Which place to give to approaches oriented on the deficit or functional performance? Is it possible to codify criteria of indication of adaptations (including computer) and their learning? What therapeutic strategy in the event of co-morbidity?
