Création et pré-étalonnage de tests de tâches nouvelles évaluant les fonctions exécutives de patients cérébrolésés

Abstract : Goal : The executive impairment is one of the most frequent and disabling aftereffect of a serious brain damage. There is often a dissociation between the results of the usual neuropsychological tests that are well-structured, and the impairments that the patients meet in their daily life. These disabilities that emerge in many cases while doing nonroutine activities, frequently require new patterns of actions. Therefore, we have developed three tests in order for the patient to be faced with a novel daily-life activity allowing to carry out sequenced appraisals.
Material : These three tests require to make a chocolate box, a recipe sorter and a pillbox. We drew up the instructions, chose the required supplies and developed a simple but efficient rating system. We carried out a data standardisation on 30 subjects and reviewed the tests results of four patients.
Results : No correlation was found on raw scores between the three tests. On the other hand, we noticed a high and significant correlation with the time that people spent on completing the tests. We carried out a qualitative analysis of the results of 4 patients.
Discussion : The instructions, the rating system, or the size of control population may explain these results. Time is a crucial element of the quotation as it reflects implicitely wanderings and hesitations.
Conclusion : The rating system will have to be modified and a greater number of controls included to refine results of this study.
