#contracture

• Abendroth sign — A medical eponym derived from German onomastics, historically used in neuro-semiology and in describing motor dynamic anomalies (the Abendroth reflex or sign). In old treatises on clinical neurology, the term identified a particular alteration of deep tendon reflexes or a form of intermittent muscular contracture observed in patients with neurosyphilis or advanced states of catatonia. This sign was evaluated within the differential diagnosis of decerebrate rigidity and psychotic manifestations with an organic brain substrate.
• Antispasmodic — Orthographic variant accepted for antispasmodic; the property of a pharmaceutical compound or plant extract to inhibit increased motility and involuntary contractions in the smooth muscles of hollow organs. As a noun, it represents an active substance frequently prescribed for the rapid relief of acute pain caused by biliary, urinary, or intestinal crises.
• Arthrogryposis — A rare congenital condition characterized by the presence of multiple and fixed joint contractures, manifested by stiffness and severe limitation of mobility from birth. This non-progressive pathology, often associated with hypotrophy of the surrounding muscles, typically affects multiple body segments symmetrically and is caused by reduced intrauterine fetal movement during embryonic development.
