title: Jerky dystonic shoulder following infarction of the posterior thalamus.
abstract: The syndrome of the jerky dystonic hand is recognized as a consequence of infarction of the posterior thalamus. A patient with multiple risk factors for stroke developed jerky dystonia of more proximal involvement, affecting the shoulder and speech, several months after a stroke affecting the posterior thalamic region. The cause for the proximal, rather than distal, upper limb involvement, is unclear, and is not apparent from the distribution of the lesion on neuroimaging. Injections of botulinum toxin significantly improved the symptoms.
