title: Dystonia: a clinical approach.
abstract: Dystonia is a common movement disorder characterised by abnormal postures of the affected body part. It has a very varied presentation and numerous causes, and this can create difficulties with diagnosis and appropriate investigation. This article aims to provide a clinical approach to patients with dystonia, focussing on how to create a differential diagnosis and to plan rational testing.
