Hysterical Paralysis

 

Hoover's sign:

 The patient should-lie supine with legs extended. Place a hand  under one heel and ask him to lift the opposite leg against resistance. If the leg  with your hand under its heel is normal, it will be pressed downwards, but if 

paralyzed, it will not be pressed. If paralysis is hysterical the leg will be pressed  down more strongly than when patient is asked to press down voluntarily. 

Babinski's rising up sign: 

 Patient should lie on the back. Ask him to sit up without support of his arms. In organic spastic paralysis, paralyzed leg is flexed at hip and is lifted from the bed while heel of the normal leg is pressed  down. This phenomenon does not occur in hysterical paralysis.
