The authors measured postural wrist tremor with accelerometry in patients with psychogenic (n = 6), essential (n = 11), and parkinsonian (n = 12) tremor. Tremor was measured in one hand, while the other hand either rested or tapped to an auditory stimulus at 3 and 4 or 5 Hz. Psychogenic tremors showed larger tremor frequency changes and higher intraindividual variability while tapping. Accelerometry may differentiate psychogenic from essential and parkinsonian tremor.
作者使用加速度计测量了心因性震颤患者（n = 6）、特发性震颤患者（n = 11）和帕金森病震颤患者（n = 12）的姿势性腕部震颤。在一只手上测量震颤，同时另一只手休息或随着3、4或5赫兹的听觉刺激进行敲击。心因性震颤在敲击时显示出更大的震颤频率变化和更高的个体内变异性。加速度计可能有助于区分心因性震颤与特发性震颤和帕金森病震颤。
