A forme fruste of progressive idiopathic dystonia is reported in a girl, starting at eight years and followed to 24 years of age. The first symptom was isolated dystonia of the left foot and later writer's cramp developed in the hands. Fluctuations of the dystonia occurred later in the course of the disorder, which were not related to the sleep-walking cycle. Complete remission of symptoms was obtained with low dosage of L-dopa. This case broadens the spectrum of fluctuating dopa-sensitive progressive childhood dystonias and provides evidence for writer's cramp being a form of focal dystonia.
报告了一名女孩患有进行性特发性肌张力障碍的顿挫型，起病于8岁，随访至24岁。首发症状为左脚孤立性肌张力障碍，后来手部出现书写痉挛。肌张力障碍的波动在疾病过程后期出现，与梦游周期无关。低剂量左旋多巴使症状完全缓解。该病例拓宽了波动性多巴敏感型进行性儿童肌张力障碍的范围，并为书写痉挛是局灶性肌张力障碍的一种形式提供了证据。
