Which test is commonly used to screen for carpal tunnel syndrome?

Screening for carpal tunnel syndrome relies on provocative maneuvers that stress the carpal tunnel to reveal median nerve issues. Phalen's test is performed by holding the wrists in full flexion for about a minute, which increases pressure within the carpal tunnel. A positive result is numbness, tingling, or pain in the median nerve distribution (thumb, index, middle finger, and radial half of the ring finger). This directly tests the environment around the median nerve and its ability to function when compressed, making it the most commonly used screen for CTS in quick clinical or exam settings. The other tests focus on different problems: Finkelstein's test checks for De Quervain's tenosynovitis (pain along the thumb-side of the wrist with thumb movement), the Allen test evaluates arterial patency in the hand, and Froment's sign assesses ulnar nerve dysfunction by looking at thumb adduction weakness.
