In addition to its clinical testing role, the laboratory’s research objectives include application of multivariate statistics to increase the sensitivity and specificity of clinical tests, and transitional research in vestibular prostheses. With collaborators in Geneva, we have shown that acute simulation of the human posterior ampullary nerve produces robust eye movements, thus supporting the development of vestibular implants. We have worked with many collaborators to show that a non-invasive balance aid that provides subjects with feedback about the tilt of their body from the vertical can help them stand and walk more securely.
