THE RELATION BETWEEN PHYSIOLOGICAL TREMOR AND THE 13-HZ OSCILLATIONS OF THE ARM MUSCLES

In a previous article the author has demonstrated regular 13-Hz oscill ations of the bellies of the arm muscles during isometric contractions . In this research these experiments were extended with the study of p hysiological tremor by application of an accelerometer on the wrist. D uring repeated isometric and faradic contractions of the arm muscles, an harmonic relation between this physiological tremor and the 13-Hz o scillations was proved. Also it is plausible to consider these 13-Hz o scillations as the primary origin of the physiological tremor.
