Abstract

Five patients presenting with isolated tremors of the trunk or neck are described. Their clinical features were similar to seven other patients who presented with head tremor, or arm and head tremor, but then eventually developed obvious torticollis, sometimes with arm dystonia. We conclude that isolated tremor of the trunk or head, especially of slow frequency (2–5 Hz), and in the case of the head in a “no-no” direction, may be the initial manifestation of focal dystonia.
