Hyperthyroidism is associated with various movement disorders, such as chorea and tremors. We report on a young Chinese woman with an unusual presentation of myoclonus, involving both platysmal muscles, in association with subclinical hyperthyroidism. The myoclonus was preceded by symptoms of hyperthyroidism, namely weight loss, menstrual disturbances, and heat intolerance. The movements abated with clonazepam and hyperthyroidism was treated with carbimazole. The myoclonus recurred briefly when she stopped taking clonazepam, but she has since remained well and euthyroid.
甲状腺功能亢进与多种运动障碍有关，如舞蹈症和震颤。我们报告了一名年轻中国女性，她表现出不寻常的肌阵挛，累及颈阔肌，同时伴有亚临床甲状腺功能亢进。该肌阵挛之前出现了甲状腺功能亢进的症状，即体重减轻、月经紊乱和不耐热。使用氯硝西泮后肌阵挛症状减轻，使用卡比马唑治疗甲状腺功能亢进。当她停止服用氯硝西泮时，肌阵挛短暂复发，但此后她一直状况良好，甲状腺功能正常。
