Psychogenic dystonia induced by peripheral trauma. Case report Distonia psicogênica induzida por trauma periférico. Relato de caso

The origin of dystonia is a point of discussion since its first description. A cause-and-effect relationship between brain injury and subsequent movement disorder is well established, but the existence of such a relationship following peripheral injury has not been universally accepted. This paper has the objective to report a patient with fixed dystonic posture of the hand after peripheral trauma.
