Which screening test reproduces paresthesias in carpal tunnel syndrome?

Explanation:
Phalen maneuver reproduces paresthesias in carpal tunnel syndrome. By flexing the wrists fully against each other for about a minute, the pressure inside the carpal tunnel increases and compresses the median nerve, provoking symptoms in its distribution (thumb, index, middle finger, and radial half of the ring finger). This simple test is a classic screening maneuver for CTS. By contrast, Tinel sign involves tapping over the carpal tunnel to elicit symptoms, Froment’s sign detects ulnar nerve weakness of the adductor pollicis, and the Finkelstein test screens for De Quervain tenosynovitis.
