Evolution physiologique des paramètres d'équilibre sur Equitest chez l'adulte sain âgé de 20 à 60 ans

Objectifs Le sens de l’equilibre depend d’une multitude de facteurs dont l’âge. Les praticiens consacrent un temps considerable pour elucider et traiter les problemes d’equilibre dans une population ou l’esperance de vie s’accroit. Depuis ces dernieres decades, les plates-formes dynamiques informatisees (PDI) apportent aux cliniciens un moyen d’evaluer objectivement les troubles de l’equilibre. Le but de cette etude est d’evaluer l’evolution physiologique des parametres d’equilibre chez l’adulte sain âge de 20 a 60 ans. Materiel et Methodes 108 adultes volontaires sains ont ete inclus dans cette etude. La PDI Equitest a ete utilisee pour mesurer les parametres d’equilibre dans quatre groupes d’âge : 20-30, 3040, 40-50 et 50-60 ans. Resultats Les parametres d’equilibre s’alterent progressivement avec l’âge dans nos groupes etudies, en particulier les performances vestibulaires, alors que la dependance visuelle s’accroit. Conclusion Nos resultas montrent que : 1- la presbyvestibulie est un phenomene physiologique d’apparition tres progressive avec l’âge. 2- entre 20 et 60 ans, les valeurs normatives doivent etre etablies sur des tranches d’âges etroites, de l’ordre de la decennie. 3- Sur un plan preventif se pose la question de savoir si ce phenomene est ineluctable ou peut etre contrecarre par une reeducation ou un traitement adapte.
