The signs of dystonic tremor: Tremulous “escanciador”
The present case has been published in the journal Neurology.
A 58-year-old woman noticed right-hand jerky tremor exclusively while curling her hair. Her tremor-generating posture was reminiscent of the Asturian pourer of cider, or “escanciador,” who holds the bottle above the head when vertically pouring to aerate the liquid (figure).

On examination, we asked her to hold a water bottle as if it were a hair curler. This elicited an action-induced, position-dependent, task-specific, weight-sensitive tremor, which attenuated when touching her affected hand with the unaffected one (closed-loop sensory feedback or sensory trick) (video available).

The rest of the examination was normal. These 5 clinical features distinguish dystonic tremor from all other tremor syndromes.
