Overuse or task-specific dystonia has been described in a number of professions characterized by repetitive actions, typically affecting the upper extremities. Cervical dystonia (CD), however, has rarely been associated with overuse.
We present a case report of typical CD that developed in the context of chronic repetitive movements associated with the patient's professional occupation as an office manager who spent many hours per day holding a phone to his ear.
Overuse CD should be suspected when typical symptoms and signs of CD develop in the context of chronic repetitive use or overuse of cervical muscles, especially where exacerbating tasks involve asymmetric postures.
在许多以重复性动作为特征的职业中，已出现过使用过度或任务特异性肌张力障碍，通常影响上肢。然而，颈部肌张力障碍（CD）很少与使用过度相关。
我们报告一例典型的CD病例，该病例发生在与患者职业相关的慢性重复性动作背景下，患者是一名办公室经理，每天花费数小时将电话贴在耳边。
当在颈部肌肉慢性重复使用或过度使用的背景下出现典型的CD症状和体征时，应怀疑为使用过度性CD，尤其是在加重症状的任务涉及不对称姿势的情况下。
