震颤作为最常见的运动障碍表型之一,是指全身任意部位呈现一定频率和振幅的节律性、无意识性肌肉收缩。按发作起源,其可分为生理性震颤和病理性震颤;按发作时体位,其可分为静止性、运动性和姿势性震颤;按发作频率,其又可分为低频、中频和高频率震颤。无论是患者,还是正常人,每个人一生可能都会经历震颤。因此,除了采用临床体检评估震颤外,也可借助以震颤电图为代表的电生理手段客观量化震颤,以帮助鉴别诊断、疗效评估及预后判断,这 Tremor, one of the most common manifestations of dyskinesia, is a rhythmic, involuntary muscle contraction at a certain frequency and amplitude in any part of the body. According to the origin of the attack, which can be divided into physiological tremor and pathological tremor; seizure position, which can be divided into static, motor and postural tremor; according to seizure frequency, which can be divided into low frequency, medium frequency and high frequency Tremor. Whether it’s a patient or a normal person, everyone may experience tremor throughout their lives. Therefore, in addition to clinical tremor assessment of tremor, but also by means of electrophysiological tremor electrogram to quantify the objective quantification of tremor to help differential diagnosis, evaluation of the efficacy and prognosis, which
