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.
