特发性震颤（ET）是神经系统疾病中最常见的误诊。目前的目的是提供观测数据的基本特征，即，相对严重的姿势性震颤的动力。对369例ET患者进行横断面研究。姿势性震颤评分（0-3分）和动力性震颤评分（0-3分）在标准化神经系统检查期间进行分配。在绝大多数病例中（~95%），运动性震颤比姿势性震颤更严重。在近三分之一（32.8%）的病例中，运动性震颤评分比姿势性震颤评分高1分以上。相反，只有少数病例（~5%）的姿势性震颤甚至比运动性震颤稍微严重（<1分），并且在任何情况下姿势性震颤评分均不高于运动性震颤评分>1分。在每一个姿势性震颤评分中，几乎所有病例都有运动性震颤或更多。震颤的主要类型是运动性的而不是姿势性的。识别震颤现象学的简单、经验性特征对临床医师具有潜在的诊断价值。
Essential tremor (ET) is among the most commonly misdiagnosed neurological diseases. The current aim was to provide observational data on a basic characteristic of ET, namely, the relative severity of postural to kinetic tremor. 369 ET cases were enrolled in a cross-sectional study. Postural tremor scores (0-3) and kinetic tremor scores (0-3) were assigned during a standardized neurological examination. In the vast bulk of cases (~95%), kinetic tremor was more severe than postural tremor. In nearly one-in-three cases (32.8%), the kinetic tremor score was >1 points higher than the postural tremor score. Conversely, in only a few cases (~5%) was postural tremor even marginally (<1 point) more severe than kinetic tremor, and in no case was the postural tremor score >1 point higher than the kinetic tremor score. At each postural tremor score, nearly all cases had that amount of kinetic tremor or more. The primary type of tremor in ET is kinetic rather than postural. Recognition of the simple, empirical features of tremor phenomenology has potential diagnostic value for practicing clinicians.
