Abstract:
OBJECTIVE: To summarize and analyze the characters, pathogenesis and influencing factors of various tremors, so as to provide evidence for the identification, prevention and treatment of various tremors in clinic.DATA SOURCES: A computer-based online search of Medline database was undertaken to identify articles about tremor published in English between January 1998 and May 2005 with the keyword of "tremor". Meanwhile, Chinese relevant articles published between January 1998 and May 2005 were searched with computer in Chinese full-text journal net by using the keyword of "tremor" in Chinese. STUDY SELECTION: The data were primarily checked. Inclusive criteria: ① articles about the classification, etiological factors and influencing factors of tremor; ② retrospective investigation on specific events. Exclusive criteria: repetitive studies.DATA EXTRACTION: Totally 48 articles were collected, and 31 repetitive studies were excluded. Of the other 17 ones accorded with the inclusive criteria, 9 were the investigations about tremor, and 8 were the specific cases of tremor.DATA SYNTHESIS: Tremor is classified mainly according to its manifestations and the etiological factors of basic disease. Mechanical tremor,reflexion of central nervous system and central oscillator are the pathogenesis of tremor. According to the manifestations, tremor canbe classified into static tremor, kinetic tremor, essential tremor, postural tremor, unfixed tremor. According to the different etiological factors, tremor can be classified into enhanced physiological tremor, essential tremor syndrome (classical essential tremor, orthostatic tremor, task-specific tremor, undetermined tremor), dystonic tremor, cerebellar tremor, Holmes tremor, peripheral neuropathic tremor, drug-induced and toxic tremor and psychogenic tremor,and different treatments should be adopted according to different etiological factors in clinic.CONCLUSION: Tremor has similar manifestations, but the pathogenesis are different, so different treatments should be adopted according to different etiological factors in clinic.
