Which of the following tests is associated with checking for median nerve compression?

Phalen's Test is specifically designed to assess for median nerve compression, particularly in the context of carpal tunnel syndrome. During this test, the patient is asked to flex their wrists and hold them in this position for a certain duration, typically 60 seconds. If this position provokes symptoms such as tingling, numbness, or pain in the fingers innervated by the median nerve (specifically the thumb, index, middle, and half of the ring finger), it indicates that there may be pressure on the median nerve within the carpal tunnel.

This test is particularly effective because it reproduces symptoms associated with median nerve irritation or compression. The mechanics of wrist flexion can exacerbate the symptoms of carpal tunnel syndrome, thus making Phalen's Test a useful diagnostic tool for clinicians.

Other tests like Finkelstein's Test, which is primarily used to check for de Quervain's tenosynovitis, Tinel's Test, which can also indicate nerve issues but is not confined to the median nerve, and Carpal Compression Test, while related to carpal tunnel syndrome as well, do not have the same specificity to the median nerve's response as Phalen's Test does.
