Reversal of thalamic hand syndrome by long-term motor cortex stimulation.
The authors describe a case of complete recovery from the so-called "thalamic hand" syndrome following chronic motor cortex stimulation in a 64-year-old man suffering from poststroke thalamic central pain. As of the 2-year follow-up examination, the patient's dystonia and pain are still controlled by electrical stimulation. It is speculated that a common mechanism in which the thalamocortical circuit loops are rendered out of balance may sustain hand dystonia and central pain in this case of thalamic syndrome. To the authors' knowledge this is the first reported case of its kind.
