Oscillation in the stretch reflex arc and the origin of the rhythmical, 8–12 c/s component of physiological tremor

Abstract

1. A brief downward, stepwise displacement applied to the outstretched finger gives rise to a train of approximately sinusoidal movements of it, lasting often more than 1 sec. The frequency of these waves is the same, in any one subject, as that of physiological tremor.
