Abstract
A method and system for provoking gait disorders, such as freezing of gait; usable, for example, for diagnosing and/or treatment thereof. In an exemplary embodiment of the invention, displays of situations calculated to cause freezing of gait are presented to a subject, optionally using virtual reality displays. Optionally or alternatively, incipit freezing of gait is identified using changes in gait parameters, and optionally used to guide attempts at causing freezing of gait. Optionally or alternatively, a portable device is provided which detects incipit freezing of gait and generates a corrective signal to the subject.
