Merci !
On en apprend tous les jours !
J'ai cherch� sur l'incroyable Google, autant en
faire profiter les autres. Vous connaissiez �a, les gaulois ? La d�rive en
pronation ? Je parie que si on demande � nos neurologues ils diront que ce n'est
pas un bon signe !
"Next, ask the patient to extend and raise both arms in
front of them as if they were carrying a pizza. Ask the patient to keep their
arms in place while they close their eyes and count to 10. Normally their arms
will remain in place. If there is upper extremity weakness there will be a
positive pronator drift, in which the affected arm will pronate and
fall. This is one of the most sensitive tests for upper extremity
weakness.
Pronator drift is an indicator of upper motor neuron weakness. In upper motor neuron weakness, supination is weaker than pronation in the upper extremity, leading to a pronation of the affected arm. This test is also excellent for verification of internal consistency, because if a patient fakes the weakness, they almost always drop their arm without pronating it. The patient to the left does not have a pronator drift.
