There have been few reports on the surgical treatment of secondary hemidystonias, most of which are due to basal ganglia stroke or trauma. We present 2 patients with hemidystonia secondary to thalamic hemorrhage whom we successfully treated with unilateral globus pallidus internus (GPi) stimulation. Case 1 is a 56‐year‐old man with abnormal posturing and intolerable muscle contraction pain in the left arm. Case 2 is a 73‐year‐old woman who developed severe abnormal posturing in the right arm and gait disturbance due to hyperextension of the right leg. The dystonic symptoms of both patients were refractory to medication. Three months after the inception of high frequency GPi stimulation, the motor scores on the Burke‐Fahn‐Marsden Dystonia Rating Scale were improved by 49.2% and 34.3% in Cases 1 and 2, respectively. We suggest GPi stimulation as a possible alternative to treat secondary hemidystonia. © 2008 Movement Disorder Society
