The clinical differentiation of tremors of organic and psychogenic origin can be difficult. We describe a patient with unilateral upper limb tremor that was initially considered to have a psychogenic cause, but subsequent frequency analysis of EMG signals and accelerometer recordings indicated that the tremor was organic in nature. An ischemic lesion in the contralateral lentiform nucleus found on MRI supported this conclusion. Quantitative electrophysiologic studies may thus be useful in distinguishing organic from psychogenic tremor.
器质性和心因性震颤的临床鉴别可能具有挑战性。我们描述了一名患有单侧上肢震颤的患者，该震颤最初被认为是心因性的，但随后对肌电信号和加速度计记录进行的频率分析表明，该震颤本质上是器质性的。MRI检查发现对侧豆状核有缺血性病变，支持了这一结论。因此，定量电生理研究可能有助于区分器质性震颤和心因性震颤。
