| puddle sign | <clinical sign> A sign of free abdominal fluid: the patient assumes a position on all fours; one flank is percussed by repeated light flicking of constant intensity while a Bowles-type stethoscope is placed over the most dependent portion of the abdomen and gradually moved toward the flank opposite the percussion; a sharp increase in the intensity of the sound picked up by the stethoscope indicates the level of fluid.

| Hoover's sign | <clinical sign> The patient is asked to lie supine on a couch, and when asked to raise one leg, they involuntarily make counter pressure with the heel of the other leg. If this leg is paralysed, whatever muscular power is preserved in it will be exerted in this way, or if the patient attempts to lift a paralysed leg, counter pressure will be made with the other heel, whether any movement occurs in the paralysed limb or not. This sign is not present in hysteria or malingering, a modification in the movement of the costal margins during respiration, caused by a flattening of the diaphragm, suggestive of empyema or other intrathoracic condition causing a change in the contour of the diaphragm.
