ABSTRACT=Dystonia and tremors have been recently refined and reserved explicitly for rhythmic oscillatory movements, while irregular, jerky movements, previously categorized under tremor in dystonia, are now distinctly classified as jerky dystonia. This special issue of tremor and dystonia highlights the updated evidence of both movements in dystonia. Irregular head tremors or jerky cervical and segmental dystonia were more common than regular head tremors and associated with different dystonia characteristics. Tremors in focal dystonia had distinct clinical and electrophysiological features from segmental dystonia, suggesting the influence of altered dystonia networks on tremor physiology. The underlying physiology of task-specific tremors was reviewed and showed that it should be in the subtype of tremor in dystonia rather than being one type of essential tremor or maybe a unique entity. Patients with cervical dystonia and tremors showed subtle gait abnormalities and varied responses to botulinum neurotoxin injection, possibly due to modulation of proprioceptive feedback. Taken together, studies in this Special Issue of Dystonia and Tremor have added valuable information in this field.
