Dynamische Stand- und Gangkontrolle
Sensory contributions to dynamic balance control
Principle Investigator: PD Dr. rer. nat, M.A. Max Wühr
Objectives:
Our group is interested in the interplay between sensory feedback and predictive feed-forward mechanism in the regulation of healthy and pathological stance and gait. Another research focus is devoted to the development of new, clinically implementable techniques for an automated assessment and classification of postural and gait impairments. Using these techniques, we examine the consequences of disturbed peripheral and central sensory regulation of posture and develop predictive models for the identification of postural instability and risk of falling. A therapeutic focus of our research addresses the development of a new, non-invasive vestibular balance prosthesis based on the phenomenon of vestibular stochastic resonance.
I) Interplay between sensory feedback and predictive feed-forward regulation of stance and gait
II) New vestibular stimulation paradigms for treatment of patients with vertigo and balance disorders
III) Pathophysiological mechanisms underlying subjective imbalance and vertigo
