Psychogenic dystonia induced by peripheral trauma: case report

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. A origem da distonia continua sendo controversa como nas suas primeiras descricoes. A relacao de causa e efeito entre traumatismo craniano e disturbios do movimento esta bem estabelecida, no entanto, a existencia de tal relacao apos trauma periferico nao e amplamente aceita. Este trabalho tem por objetivo relatar um paciente com postura distonica fixa da mao apos trauma periferico.
