IN THE last few years, research on abnormal movements has mainly concentrated on the central nervous system mechanisms using stereotaxic surgery, but the role of peripheral factors has only been touched on occasionally and we consider that it has been underestimated. However, several authors^1,2 have noted that particular postures evoke certain tremors. In such cases, the contraction of specific muscular groups acts as a tremorogenic stimulus of peripheral origin.

To define the conditions in which such tremors appear, we directed our studies towards "postural tremors." Contrary to resting tremors, they do not appear under normal conditions of relaxation. As will be shown, such tremors spread from a muscle or a muscular group to the other muscles of the limb; the muscle in which the rhythmic activity originates will be designated as the "inductor muscle" (or pace-maker muscle). Anesthetic infiltration of this muscle stops the rhythmic phenomena in all . . . [Full Text PDF of this Article]
