Abstract

Background:

Primary writing tremor (PWT) is a rare condition; tremor occurs primarily while writing rather than during other tasks.

Phenomenology Shown:

We illustrate the phenomenology of PWT and point out associated subtle dystonic posturing on neurological examination.

Educational Value:

PWT is a tremor disorder that shares clinical features with both dystonia and essential tremor.

KEYWORDS:

Primary writing tremor; dystonia; essential tremor; writer’s cramp
