肌张力障碍(dystonia)定义为运动障碍性病变,其特征是持续性或间歇性肌肉收缩,可引起异常运动或/和姿势,常常重复出现。肌张力障碍性运动一般有其模式,有扭曲动作,并且可能呈震颤性。肌张力障碍常常因随意动作而启动或加重,且伴随有溢出的肌肉激活(2013年新定义)[1]。最近,肌张力障碍按临床特征和病因学两条主线进行分类[1]。 Dystonia is defined as a dyskinetic disorder characterized by persistent or intermittent muscle contractions that can cause abnormal movements or / and postures, often recurring. Dystonia typically has its own pattern of movement, twisting movements, and may be tremor. Dystonia is often initiated or exacerbated by random movements and is accompanied by spilled muscle activation (new definition in 2013) [1]. Recently, dystonia was classified according to two main lines of clinical characteristics and etiology [1].
