Abstract

The variation of the amplitude and frequency of finger tremor was studied in 190 subjects ranging in age from 7 to 77 years. Tremor was measured in various postures with an accelerometer and a transduced signal was analysed by Fourier analysis. The variation of tremor frequency and amplitude with age depended upon the posture adopted for measurement and in certain postures some of the variation was related to changes in stature with age.

摘要

对190名年龄在7岁至77岁之间的受试者的手指震颤幅度和频率变化进行了研究。使用加速度计在各种姿势下测量震颤,并通过傅里叶分析对转换后的信号进行分析。震颤频率和幅度随年龄的变化取决于测量所采用的姿势,在某些姿势下,部分变化与随年龄增长的身高变化有关。
