title: Arm tremor in cervical dystonia--is it a manifestation of dystonia or essential tremor?
abstract: The classification of arm tremor in cervical dystonia is a controversial issue. There have been many, at times passionate disputes in the movement disorder community about whether it should be classified as a manifestation of dystonia or essential tremor associated with dystonia. There are arguments in favor of both views. Settling the issue might be relevant to the understanding of the etiological, presumably genetic, background because phenomenological grouping is the starting point for genetic analyses. From this point of view, we outline this tremor debate and add some new clinical data.
