The Lazarus sign or Lazarus reflex is a reflex movement in brain-dead or brainstem failure patients,[1] which causes them to briefly raise their arms and drop them crossed on their chests (in a position similar to some Egyptian mummies).[2][3] The phenomenon is named after the Biblical figure Lazarus of Bethany,[4] whom Jesus raised from the dead according to the Gospel of John.
