Froment’s Sign
Froment’s sign is a test for Ulnar Nerve palsy, specifically testing the action of Adductor Pollicis. To perform this test, ask the patient to hold a piece of paper in between her thumb and index finger and attempt to pull the paper from the patient’s grip. A normal test is when the patient is able to maintain ahold of the paper. A positive test is when the patient compensates by flexing her Flexor Pollicis Longus to maintain her grip.
