A quantitative measurement of tremor.
A quantitative measurement of tremor was achieved by means of separate analysis of frequency and amplitude, using an EEG spectrum analyser and an amplitude histogram plotter (giving distribution curve), with magnetic tape storage. Tremors were registered bilaterally from most proximal finger joints and elbow joints.
