How is de Quervain’s tendinosis diagnosed?

The test most often used to diagnose de Quervain’s tendinosis is the Finkelstein test. Your doctor will ask you to make a fist with your fingers wrapped over your thumb. Keeping your hand in a fist position, the wrist is moved up and down — the motion of shaking someone’s hand. In this test, the swollen tendons are pulled through the narrowed sheath. If this movement is painful, you may have de Quervain’s tendinosis.
