#contracture

• Abendroth - 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.
