title: Posttraumatic hemidystonia treated with unilateral globus pallidus interna stimulation: Long-term follow-up and radiologic features.
abstract: OBJECTIVE
  Hemidystonia is a unilateral clinical presentation of dystonia, and it is usually refractory to current methods of medical treatment. Recently, deep brain stimulation has given some hope of recovery to dystonic patients.
  
  
  METHODS
  A 30-year-old right-handed man with no abnormal perinatal history or family history of movement disorders was admitted to our institution. The patient had suffered right-sided dystonia for more than three years after severe head trauma sustained four years prior.
  
  
  RESULTS
  We performed a stereotactic implantation of an electrode into the left globus pallidus internus (GPi) and he showed excellent response to pallidal stimulation during long-term follow-up.
  
  
  CONCLUSIONS
  We present a unique case of secondary posttraumatic hemidystonia treated with contralateral GPi stimulation with an excellent outcome. Pallidal stimulation can be a good treatment option for posttraumatic hemidystonia in selected cases.
