Asterixis is a tremor or movement disorder characterized by movement of hands and wrists that resembles flapping of wings. There is arrhythmic flexion movements of the hands with outstretched arms and dorsiflexion of the wrists. This tremor experienced is involuntary and cannot be controlled by the individual.
Adams and Foley first described asterixis in 1949 in patients with advanced hepatic encephalopathy. [1] It is a disorder of motor control characterised by brief, arrhythmic interruptions of sustained voluntary muscle contraction usually observed due to brief lapse of posture.ecently mini-asterixis which is a part of the spectrum of the gross flapping tremor seen in hepatic encephalopathy was proposed as being due to the involvement of motor cortex causing a pathologically slowed and synchronised motor cortical wave.
