• Astasia — A neurological or psychiatric symptom manifested by the total inability or severe difficulty to maintain an erect position of the body (standing up), without the patient presenting actual muscle paralysis; it is caused by lesions in the cerebellum, frontal lobe, or by psychogenic conversion disorders, often appearing in structural correlation with abasia (inability to walk), forming the clinical syndrome known as astasia-abasia.
• Astaso- — A scientific combining form used as a prefixoid in international medical terminology to introduce the concept of astasia (inability to stand erect); it originates from Greek and serves exclusively to form compound words within the sphere of motor pathology and neurology (such as astasia-abasia, the syndrome combining the inability to stand and to walk).
• Astasobasophobia — A rare and complex phobic disorder manifested by an intense, irrational, and pathological fear of standing up (astasia) and walking (basasia), frequently associated with the obsessive fear of losing balance and falling down, in the absolute absence of any organic motor or neurological lesion that would physically justify this inability.
