Abstract:

Functional tremor is the most common subtype of functional movement disorder (FMD). At present, there is no "gold standard" for diagnosis. Most clinical manifestations coincide with organic tremor, which can easily lead to misdiagnosis and mistreatment. Characteristic electrophysiological manifestations can provide objective and repeatable diagnostic information, effectively supplement the history and physical examination, and can also be used in the differential diagnosis from organic tremor. This article reviews the electrophysiological characteristics of functional tremor and its application in diagnosis and differential diagnosis, in order to improve the clinical understanding of this disease.

摘要：

功能性震颤是功能性运动障碍的最常见亚型，目前尚无诊断“金标准”，多数临床表现与器质性震颤重合，易误诊、误治。特征性电生理学表现可提供客观、可重复的诊断信息，有效补充病史和体格检查，也可用于与器质性震颤的鉴别诊断。本文综述功能性震颤电生理学特征及其在诊断与鉴别诊断中的应用，以提高临床对疾病的认识。
