Hoover's Sign for Functional Lower Extremity Paralysis Used to distinguish organic from functional leg hemiparesis. Ask the patient to flex their weak leg at the hip. In normal people and in patients with an organic hemiparesis you will feel downward pressure under the opposite heel. If you feel nothing it suggests a functional weakness, i.e. that effort is not being transmitted to either leg. #Hoovers #Sign #Leg #Paralysis #hemiparesis #clinical #video #physicalexam #neurology #psychiatry
