Rapid eye movements, having high velocity and low amplitude, are described in 11 patients with myasthenia gravis. These movements occur with various degrees of ophthalmoplegia. To distinguish them from the somewhat similar lid-twitch phenomenon, they are called quiver movements. We believed that their presence is pathognomonic of myasthenia and results from a differential involvement of the two myoneural mechanisms that are peculiar to the extraocular muscles.
在11例重症肌无力患者中观察到了快速眼球运动，其速度快、幅度小。这些运动伴有不同程度的眼肌麻痹。为了将它们与 somewhat similar睑抽搐现象区分开来，将其称为颤动运动。我们认为它们的存在是重症肌无力的特征性表现，是由眼外肌特有的两种肌神经机制的不同受累所致。
