Project Description

My research projects interest in the neuro-biomechanical mechanisms involved in the control of balance during upright posture and movement like gait or balance recovery. I am particularly interested in determining how and based on which sensory information humans are able to detect their movements and possible loss of balance. To reach this objective, I am studying how balance perturbations are perceived and integered by the central nervous system and how a proper and adapted muscular response to this perturbation is constructed and executed. My main project interests in the contribution of the vestibular system ("balance" sensory system situated in the inner ear) to the control balance during locomotor transitions such as gait initiation, gait termination, turnings and reactive steps. The promising results encourage a theory that might explain the freezing problematic in Parkinsonnian patients (collaboration with Dr. Mark Carpenter). Another project interests in which characteristics of a balance perturbation are perceived when humans are actively balancing, and to determine the perception thresholds of these characteristics. These results will provide determinant insights to further study the balance mecanisms engaged in prevention of a fall. Future studies are considered with populations at risk of fall such as elderly, post-stroke patients, etc.
