We describe an uncommon movement disorder after stroke. A 70‐year‐old man was admitted for a right thalamic haemorrhage and 1 week later developed bilateral contractions of the face. Electromyographic study revealed a bilateral facial dystonia. The association of this bilateral facial dystonia and vertical gaze palsy produced the aspect of a “risus sardonicus.” © 2003 Movement Disorder Society
