This paper deals with the recording of finger microtremor using a self-constructed apparatus (amplitudes 0.5 to 0.05 mm). 32 healthy subjects aged 7 to 60 years were examined by means of a test set permitting the exact recording of the amplitudes and frequencies of the right middle finger movement. Special attention was given to the vertical plane of the tremor in order to permit more exact demonstration. Frequencies of 5 to 12 cps. were recorded, the mean frequency being 7.55+/-1.12 cps. The minimum amplitude was 0.02 and the maximum recorded amplitude amounted to 1.4 mm, with a mean amplitude of 0.12+/- 0.07 mm. No significant differences in amplitude or frequency were noted with respect to age or sex. This method is useful in the accurate quantitative assessment of every kind of tremor.
本文论述了使用自行构建的仪器记录手指微震颤（振幅为0.5至0.05毫米）。通过一套测试装置对32名年龄在7至60岁的健康受试者进行了检查，该装置能够精确记录右手食指运动的振幅和频率。为了更精确地展示，特别关注了震颤的垂直平面。记录到的频率为5至12赫兹，平均频率为7.55±1.12赫兹。最小振幅为0.02，记录到的最大振幅为1.4毫米，平均振幅为0.12±0.07毫米。在振幅或频率方面，未发现年龄或性别存在显著差异。这种方法有助于对各类震颤进行准确的定量评估。
