目的:总结并分析各类震颤的特点及其机制和影响因素,为临床上各类震颤的鉴别及防治提供依据。资料来源:应用计算机检索Medline1998-01/2005-05关于震颤的文章。检索词“tremor”并限定文章的语种类为English。同时利用计算机检索中国期刊全文数据库1994-01/2005-05的相关文章,限定文章语言种类为中文,检索词“震颤”。资料选择:对资料进行初审,纳入标准:①关于震颤的分类、病因、影响因素。②对具体事件的回顾调查研究。排除标准:排除重复性研究。资料提炼:共收集到符合上述要求的文献48篇,排除31篇重复性研究。17篇符合纳入标准:其中9篇关于震颤的调查研究,8篇关于震颤的具体案例。资料综合:震颤的分型主要有依据震颤表现形式及根据基础疾病的病因学分类。其中机械性震颤、中枢神经系统的反射、中枢性振荡器是震颤的发生机制。依据震颤表现形式分为静止性震颤、运动性震颤、特定性震颤、姿势性震颤、无定型震颤。依据震颤的不同病因又分为增强的生理性震颤、特发性震颤综合征穴经典的特发性震颤、直立性震颤、任务和姿位特异性震颤、不能分类的震颤雪、肌张力障碍性震颤、帕金森病震颤、小脑性震颤、红核震颤、周围神经病性震颤、药物及有毒物质诱发的震颤和心因性震颤,临床上应根据不同的病因采取不同的治疗措施。结论:震颤虽表现形式类似,但发生原因各不相同,临床上应根据不同的病因采取不同的治疗措施。
OBJECTIVE: To summarize and analyze the characteristics, mechanism and influencing factors of various types of tremor and provide the basis for the identification and prevention of various tremor in clinic. Source: Applied Computer Retrieved Medline 1998-01-05-05 article on tremor. The term tremor is used to define the language of the article as English. At the same time, we searched the relevant articles of Chinese Journal Full-text Database 1994-01 / 2005-05 by computer, limiting the language of the article to Chinese and the term “tremor”. Data Selection: The data were first examined, included in the standard: ① on the classification of tremor, etiology, influencing factors. ② review of specific events investigation. Exclusion Criteria: Eliminate repetitive studies. Data Extraction: A total of 48 articles meeting the above requirements were collected, excluding 31 repetitive studies. Seventeen met the inclusion criteria: nine of them investigated the study of tremor and eight of the specific cases of tremor. DATA SYNTHESIS: The classification of tremor is based primarily on the manifestation of tremor and on the etiology of the underlying disease. Which mechanical tremor, central nervous system reflex, central oscillator is the mechanism of tremor. According to tremor manifestations into static tremor, motor tremor, specific tremor, postural tremor, amorphous tremor. According to the different causes of tremor is divided into enhanced physiological tremor, idiopathic tremor syndrome point classic idiopathic tremor, upright tremor, mission and position-specific tremor, tremor snow can not be classified, dystonia Tremor, Parkinson’s disease tremor, cerebellar tremor, red nucleus tremor, peripheral neuropathy tremor, drugs and toxic substances-induced tremor and cardioversion should be clinically based on different causes to take different treatment. Conclusions: Although tremor is similar in appearance, the reasons for its occurrence are different. Clinically, different treatments should be taken according to different causes.
