Abstract
The purpose of the present paper is to describe the use of spectral analysis to characterize normal physiologic tremor derived from dynamic hind limb movements performed by rats. Rats were trained using operant conditioning to repeatedly lift a weighted ring for food rewards. Reaction forces and vertical displacement of a ring assembly were recorded for each lifting and lowering response in rear time. Power spectra and spectrograms were generated from the resultant force-time signatures to reveal the normal physiologic tremor associated with muscle activity.
