Focal hand dystonia may be task specific, as is the case with writer's cramp. In early stages, task specificity can be so specific that it may be mistaken for a psychogenic movement disorder.
We describe 4 patients who showed extreme task specificity in writer's cramp. They initially only had problems writing either a single letter or number. Although they were largely thought to be psychogenic, they progressed to typical writer's cramp.
Early recognition of this condition may provide an opportunity for early initiation of treatment.
局灶性手部肌张力障碍可能具有任务特异性，就像书写痉挛一样。在早期阶段，任务特异性可能非常具体，以至于可能被误诊为心因性运动障碍。
我们描述了 4 例表现出书写痉挛极强任务特异性的患者。他们最初只在书写单个字母或数字时出现问题。尽管他们主要被认为是心因性的，但他们进展为典型的书写痉挛。
早期认识到这种情况可能为早期开始治疗提供机会。
