The Consensus Statement on the Classification of Tremors, from the Task Force of the International Parkinson's and Movement Disorder Society was published in 2018 in response to advances in the understanding of essential tremor (ET), tremor associated with dystonia and other monosymptomatic and indeterminate tremors. This was a revision of the previous 1998 Consensus Statement. A number of problems arise from this classification and, in this manuscript, we highlight several of these. These problems relate to the definition of tremor, the definition of ET, the proposal of the term 'essential tremor plus', issues related to orthostatic tremor (OT) including the proposal of the term 'orthostatic tremor plus', and the absence of a hierarchy of terms used to classify tremor. Among the proposals we make is that the definition of tremor should acknowledge that tremor is a symptom, ET should be redefined, severity is an important characteristic for classifying and diagnosing tremor, the terms 'essential tremor plus' and 'orthostatic tremor plus' should be abandoned, and classification of tremor requires rules for creating a hierarchy of terminology.

2018 年，国际帕金森病和运动障碍学会工作组发表了《震颤分类共识声明》，以回应对特发性震颤（ET）、与肌张力障碍相关的震颤以及其他单症状性和不定性震颤的理解的进展。这是对之前 1998 年共识声明的修订。该分类存在一些问题，在本文中，我们强调了其中的几个问题。这些问题涉及震颤的定义、ET 的定义、“特发性震颤伴发”术语的提出、与直立性震颤（OT）相关的问题，包括“直立性震颤伴发”术语的提出，以及用于震颤分类的术语没有层次结构。我们提出的建议包括：震颤的定义应承认震颤是一种症状，ET 应重新定义，严重程度是对震颤进行分类和诊断的重要特征，“特发性震颤伴发”和“直立性震颤伴发”这两个术语应被摒弃，震颤的分类需要制定术语层次结构的规则。“本文是由 Daniel D. Truong、Mark Hallett 和 Aasef Shaikh 编辑的特刊“震颤”的一部分”。
