| definition |
Asterixis, more colloquially referred to as flapping tremor, is a tremor of the hand when the wrist is extended, sometimes said to resemble a bird flapping its wings. This motor disorder is characterized by an inability to maintain a position, which is demonstrated by jerking movements of the outstretched hands when bent upward at the wrist. The tremor is caused by abnormal function of the diencephalic motor centers in the brain, which regulate the muscles involved in maintaining position. Asterixis is associated with various encephalopathies due especially to faulty metabolism. 扑翼样震颤是由于基底节病变及小脑性共济失调而引起。此种震颤粗大，节律稍慢，通常呈对称性，累及上肢及下肢，肌张力高低可变。当患者平伸手指及腕关节时，腕关节突然屈曲，然后又迅速伸直，加上震颤多动，类似鸟的翅膀在扇动，故称扑翼样震颤。多见于代谢性疾病，如肝豆状核变性、肝昏迷以及尿毒症等；也见于呼吸衰竭时肺性脑病。 Abnormal involuntary movements which primarily affect the extremities, trunk, or jaw that occur as a manifestation of an underlying disease process. Conditions which feature recurrent or persistent episodes of dyskinesia as a primary manifestation of disease may be referred to as dyskinesia syndromes (see MOVEMENT DISORDERS). Dyskinesias are also a relatively common manifestation of BASAL GANGLIA DISEASES. |
