• Abasic — A medical term describing a person affected by abasia, characterized by the partial or total inability to walk or maintain an erect posture, despite muscular strength, sensation, and coordination of the limbs being completely preserved in the recumbent position. It is encountered in organic neurological conditions (frontal or cerebellar lesions, extrapyramidal syndromes) or in psychogenic conversion disorders (classical hysteria, presenting as astasia-abasia syndrome).
• Abasia — A neurological and neuropsychiatric symptom characterized by the total or partial inability to walk, whereas muscular strength, coordination of movements in the recumbent position, and sensation in the legs remain completely intact. It can have an organic cause, linked to lesions of the frontal lobe, cerebellum, or vestibular pathways, or a functional (psychogenic) cause, encountered within conversion (dissociative) disorders, where it is frequently associated with astasia (the inability to stand).
• 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.
