EquiMog : équilibre et motricité en gériatrie
2017
Introduction L’evaluation geriatrique de la motricite, et notamment de la fonction d’equilibration, est habituellement de type fonctionnel et regroupe differents tests valides [1] , [2] , [3] , [4] , [5] , [6] , [7] . Cependant, ces tests ne permettent pas d’orienter le reeducateur dans son bilan diagnostique kinesitherapique. Le raisonnement systemique a ete developpe en reponse a cette volonte d’analyse fine des troubles de l’equilibre. Le « Balance Evaluation Systems Test » (BESTest) [8] evalue le fonctionnement de six sous-unites systemiques du controle de l’equilibre. Le raisonnement EquiMoG, equilibre et motricite en geriatrie [9] , a ete developpe dans la meme logique, mais en tenant…
Real-time 3D movements analysis for a medical device intended for maintaining functional independence in aged adults at home
2016
We propose in this manuscript a realtime3D movement analysis system for inhomefunctionalabilities assessment in aged adults. As a first step, the purpose is to maintain the functionalindependence of this population and to allow an earlier detection of a motor decompensation inorder to facilitate a rehabilitation process. To quantify the equilibrium quality of a subject, webuilt a system using the Kinect sensor in order to analyze a simple clinical test validated in geriatricrehabilitation: the Timed Up and Go (TUG). Three experiments conducted in heterogeneousenvironments (laboratory, day hospital and home) showed good measurement reliability of theidentified parameters. In particular, they…
How is gravity integrated into motor planning : behavioural and fMRI approaches
2016
Gravity is immutable, ubiquitous and affects the dynamic of our daily movements. The gravitational attraction (9.81 m / s2) which varies less than 1% of the earth's surface, is an actress of the evolution of all living species. Thanks to an efficient sensorimotor system, the dynamical consequences of the effects of gravity on our movements are stored as internal representations. To circumvent the time delays of the afferent signals coming from the sensorimotor system (too long to plan quick movements), the Central Nervous System (CNS) acts in a proactive fashion by using suitable internal models developed during our past experiences. These models are mainly used during the motor planning to…
