Abstract
Characteristics of the finger tremor in normal human subjects were studied. Spectral analysis shows (i) a major peak at about 0. 3 Hz, (ii) a secondary peak at about 1 Hz, and (iii) a broad peak at about 10 Hz. The peak at 0. 3 Hz correlates well with respiration, the 1 Hz peak with the electrocardiogram and the 10 Hz peaks with the electromyogram from finger extensors. The relative contributions of these three factors in generating normal physiological tremor were measured and the previously undescribed contribution of respiration proved to be the largest. The time delays in generating each component of normal tremor were measured and possible mechanisms are suggested.
