The Lazarus sign is a reflex movement in brain-dead patients which causes them to briefly raise their arms and drop them crossed on their chests (in a position similar to some Egyptian mummies)
This happen because although the brain is dead, the spinal column isn’t and so this neural pathway can go through. 
As a consequence the movement is possible in brain-dead patients whose organs have been kept functioning by life-support machines.
