Mingazzini's sign
Examination of the Mingazzini sign is used to assess motor deficits in the upper or lower limb. It ranks among extinction (paretic) phenomena.[1]
The 'upper extremity test is performed by asking the patient to close his eyes and pronate the forearm with the palms down. For about 30 seconds, we observe the instability or drop of the upper limb. "Mingazzini" is positive if there is a drop of the entire upper limb. If only the hand drops, it is Hanzal's sign. If both upper limbs deviate to the side, it is Hautant's sign.[1]

On the lower limb we invite the patient to lie on his back, close his eyes and raise the lower limbs, which are flexed at the hip and knee to a right angle. The symptom is positive if there is a drop of the limb on the side of the paresis.[1]
