title: [Post-traumatic focal fixed dystonia of the shoulder: a distinctive syndrome with speculative mechanisms?].
abstract: BACKGROUND
  Whether post-traumatic focal fixed dystonia has a physiological or psychologically-mediated mechanism is discussed.
  
  
  METHODS
  We report the case of an active 22-year-old soldier with shoulder-fixed dystonia, eight months after a fall with minor right-acromioclavicular sprain.
  
  
  CONCLUSIONS
  Psychiatric examination and search of complex regional pain syndrome, radicular or accessory nerve damage, and genetic predisposition to dystonia are necessary for selecting a difficult treatment in these patients.
