Validation sur une population pathologique du test d’évocation lexicale orale vELO

Abstract : The vELO test is a rapid assessment tool created in order to evaluate word finding impairment (WFI) among subjects with chronic aphasia after brain injury. This test is meant to minimize the intervention of executive processing that is usually at work in verbal fluency or oral naming tasks. Normative data were collected in 2013 on 204 healthy subjects from a population-based cohort. The purpose of our study was to validate the vELO test among patients with brain injury. To achieve this, 40 patients and 120 healthy matched controls have been recruited and have completed the following procedure: vELO, semantical and phonological verbal fluency tasks, an oral naming task and a mental flexibility task. Results show that vELO detects WFI in the same way as naming or fluency tasks. Additionally, it appears to complete other tests measuring aphasia after-effects on various grammatical categories (verbs, adjectives). Finally, the study provides evidence that vELO may evaluate WFI in aphasia without interference of executive functions. Our conclusion is that vELO can be considered as a reliable and quick tool to evaluate WFI in patients with aphasia during chronic phase.
