Astasia-abasia Astasia-abasia is a form of psychogenic gait disturbance in which gait becomes impaired in the absence of any neurological or physical pathology. The person usually walks in a bizarre manner. They stagger and appear as if going to fall, but always manage to catch hold of something in time. Sometimes these people cannot even stand, but on the other hand, they are well able to move their legs while lying down or sitting. Often associated with conversion disorder or somatization disorder.
