背景：大多数正常成年人都会出现轻微的手部震颤。目前还没有对儿童中此类震颤的患病率或临床相关性进行调查。方法：对西班牙儿童进行抽搐、震颤和其他神经系统疾病的横断面研究；因此，西班牙布尔戈斯的 819 名小学生每只手都画出了阿基米德螺线。螺旋状震颤由盲法神经科医生评定为 (0-2)，并指定总体震颤评级 (0-4)。结果：平均年龄为 10.9 +/- 3.1 岁。 424 名 (51.7%) 儿童的双手均出现 1 级震颤（轻度震颤），88 名儿童 (10.7%) 双手均出现震颤。较高的震颤等级非常罕见。男孩的总体震颤评分高于女孩（1.31 +/- 0.41 vs. 1.22 +/- 0.34，p = 0.002），并且与年龄相关性较弱但显着（rho = 0.09，p = 0.01）。在受试者中，左手螺旋评分高于右手螺旋评分 (p < 0.001)。结论：在这项针对 819 名西班牙学童的横断面研究中，普遍观察到轻度震颤。与成人一样，男性比女性有更多的震颤，震颤评分随着年龄的增长而增加，左臂的震颤评分高于右臂，这表明这些临床相关性似乎更广泛地适用于儿童。儿童震颤的功能意义，特别是与书写能力相关，值得进一步研究。版权所有 (C) 2011 S.

Background: Mild hand tremor occurs in most normal adults. There are no surveys of the prevalence or clinical correlates of such tremor among children. Methods: A cross-sectional study of tics, tremor and other neurological disorders was conducted in Spanish children; thus, 819 schoolchildren in Burgos, Spain, drew Archimedes spirals with each hand. Tremor in spirals was rated (0-2) by a blinded neurologist and an overall tremor rating (0-4) was assigned. Results: The mean age was 10.9 +/- 3.1 years. A tremor rating of 1 (mild tremor) was present in either hand in 424 (51.7%) children, and in both hands in 88 (10.7%) children. Higher tremor ratings were very uncommon. The overall tremor rating was higher in boys than girls (1.31 +/- 0.41 vs. 1.22 +/- 0.34, p = 0.002) and correlated weakly yet significantly with age (rho = 0.09, p = 0.01). Within subjects, the left hand spiral rating was greater than the right (p < 0.001). Conclusions: In this cross-sectional study of 819 Spanish schoolchildren, mild tremor was commonly observed. As in adults, males had more tremor than females, tremor scores increased with age, and tremor scores were higher in the left than right arm, demonstrating that these clinical correlations seem to be more broadly generalizable to children. The functional significance of tremor in children, particularly as it relates to handwriting proficiency, deserves additional scrutiny. Copyright (C) 2011 S. Karger AG, Basel
