A 40-year-old man with an anxiety disorder developed sudden-onset right-hand tremor after a fixation wire for a tibial bone fracture was removed. He manifested a resting and action tremor with an irregular pattern. A coherence entrainment test (CET) revealed that the peak power spectral frequency of the right finger tremor was not entrained by simultaneous voluntary left finger tapping, which indicated a non-psychogenic origin. Deep brain stimulation to the left thalamic ventral intermediate nucleus abolished the tremor. We concluded that CET can determine the surgical indications for an unusual tremor that must be differentiated from that of psychogenic origin.
一位 40 岁的焦虑症患者在拆除胫骨骨折固定线后突发右侧手部震颤。他表现出静止性和动作性震颤，呈不规则模式。相干诱捕测试（CET）显示，右侧手指震颤的峰值功率谱频率未被同步的左手指敲击所诱捕，这表明震颤并非心因性起源。对左侧丘脑腹侧中间核进行深部脑刺激可消除震颤。我们得出结论，CET 可以确定手术指征，用于区分非心因性震颤。
