Tinel sign in carpal tunnel syndrome is elicited by which maneuver?

Tinel sign reflects focal irritation of the median nerve at the carpal tunnel. By percussing the nerve at the wrist, you can provoke tingling (paresthesias) in the median nerve distribution, which supports carpal tunnel syndrome. This distribution includes the thumb, index, middle, and radial half of the ring finger. Phalen maneuver, which involves wrist flexion, is a different test that can also provoke symptoms but via a different mechanism. Percussion at the elbow would test other nerves (like the ulnar nerve) and is not about the carpal tunnel.
