Postura de descerebración - Overview

Definición:

Es una postura corporal anormal que implica mantener extendidos los brazos y las piernas, los dedos de los pies apuntando hacia abajo y la cabeza y el cuello arqueados hacia atrás. Los músculos se tensionan y se mantienen rígidos. Este tipo de postura por lo general significa que ha habido daño grave al cerebro.

Consideraciones:

La causa frecuente de la postura de descerebración es una lesión cerebral grave.

El opistótonos (un espasmo muscular grave de cuello y espalda) puede ocurrir en casos graves de postura de descerebración.

La postura de descerebración puede ocurrir en un lado, en ambos lados o sólo en los brazos; puede alternar con postura de decorticación. Una persona también puede tener postura de decorticación en un lado del cuerpo y postura de descerebración en el otro lado.
