Hoover’s sign

Hoover’s sign

a diagnostic test for neurological (as distinct from psychological) hemiplegia in which the individual in a reclining position attempts to raise the paralyzed leg: An individual with true hemiplegia reflexively presses down the heel of the healthy leg during the test. The absence of the downward movement is a positive Hoover’s sign and suggests psychogenic paresis or malingering. [Charles Franklin Hoover (1865–1927), U.S. physician]
