Tinel's sign at the wrist indicates compression of which nerve?

Explanation:
Tinel's sign at the wrist is a percussion test over the carpal tunnel that, when positive, produces tingling in the distribution of the median nerve. This directly indicates irritation or compression of the median nerve as it passes through the carpal tunnel, which is the hallmark of carpal tunnel syndrome. Other tests listed–Phalen's test and its reverse version–also assess median nerve involvement but through different provocative positions, while the Finkelstein test targets De Quervain's tenosynovitis rather than nerve compression. So, the sign at the wrist specifically points to the median nerve being compressed.
