Abstract

We characterized the relationships in tremor-band activity between the 15 major superficial upper limb muscles of persons with essential tremor by quantifying the proportion of shared activity (coherence) in the tremor band and by characterizing phase differences between these muscles during various tasks. From our observations, we conclude that tremor enhances the coherence between muscle pairs throughout the upper limb in a pattern that reflects functional relationship between them.
