We describe a young man with a two and a half year history of idiopathic irregular contractions of an antitragicus muscle in the absence of a more generalized movement disorder. These contractions persisted in sleep and could not be replicated voluntarily. Because proximal nerve block temporarily eliminated the movements and complex hand movements reduced their amplitude and frequency, we suspect a central generator. However, these movements were not associated with any known pathologic condition.
我们描述了一名年轻男性，其耳屏对耳屏肌出现特发性不规则收缩已有两年半时间，且不存在更广泛的运动障碍。这些收缩在睡眠中持续存在，且无法通过自主动作复制。由于近端神经阻滞可暂时消除这些动作，而复杂的手部动作可降低其幅度和频率，我们怀疑存在中枢性起源。然而，这些动作与任何已知的病理状况均无关联。
