Nouvelle validation du test d'évocation lexicale vELO sur des patients aphasiques

Abstract : The aim of the current study is to validate a screening tool (the vELO) assessing lexical production disorders in aphasic subjects using a test of the parts of a whole of a bicycle and a test of evocation of words on definitions verbally suggested. This test is designed to highlight language deficits with reduced strain on the executive functions and without visual processing. In this way, we compared 23 aphasic patients to a group of 29 non-aphasic patients (composed of 13 head trauma patients, 1 brain anoxia patient, 10 right brain lesioned patients and 5 left stroke patients without aphasia). The participants were given an assessment of their expressive language skills and executive functions (naming, verbal fluency, flexibility). The results show that vELO is a screening test correlated to verbal fluency and denomination tasks, allowing to highlight a residual lexical production disorder in aphasic people. It has the particularity of revealing a missing word at both the noun and verb levels, by requesting executive functions to a lesser extent.
