肌张力障碍 Dystonia

(重定向自Dystonic disorders)

肌张力障碍Dystonia)是由于身体的肌肉不随意地持续收缩,造成肌肉产生变形,而无法依照自身的意思活动。

肌张力障碍是一组疾病的总称,是骨骼肌张力的病理性改变。患者的肌张力时高时低,有时只影响局部某个肌肉或肌肉群,有时则影响全身。

大多数的肌张力障碍病因并不清楚,少数可有家族遗传史,儿童和少年发病的扭转痉挛可能存在基因遗传问题。此外,很多疾病可能在临床上导致继发性肌张力障碍,如新生儿脑损伤,黄疸,窒息,脑炎,脑血管病,中毒性脑病等等。与原发性肌张力障碍相比,这类病人症状更为复杂多样,可能伴随有偏瘫,舞蹈样动作,小脑平衡障碍,智力或情感方面的问题。CT与磁共振检查也会有一些特征性的表现。

Dystonia 肌张力障碍

(重定向自Dystonic disorders)
Hyperglycemia-induced involuntary movements, which, in this case, did not consist of typical hemiballismus but rather of hemichorea (dance-like movements of one side of the body; initial movements of the right arm in the video) and bilateral dystonia (slow muscle contraction in legs, chest, and right arm) in a 62-year-old Japanese woman with type 1 diabetes.

Dystonia is a neurological movement disorder in which sustained muscle contractions cause twisting and repetitive movements or abnormal postures. The movements may resemble a tremor. Dystonia is often initiated or worsened by voluntary movements, and symptoms may "overflow" into adjacent muscles.
