Clinical assessment by history taking and physical examination can frequently diagnose CTS.
* Phalen's maneuver is performed by flexing the wrist gently as far as possible, then holding this position and awaiting symptoms. A positive test is one that results in numbness in the median nerve distribution. The quicker the numbness starts, the more advanced the condition.
* Tinel's sign, a classic, though less specific test, is a way to detect irritated nerves. Tinel's is performed by lightly tapping (percussing) the area over the nerve to elicit a sensation of tingling or "pins and needles" in the nerve distribution.
* The carpal compression test, or applying firm pressure of the palm over the nerve to elicit symptoms has also been proposed.
If, based on history and physical examination, a CTS diagnosis is suspected but not clear, patients will likely be tested electrodiagnostically with nerve conduction studies and electromyography; MRI or ultrasound imaging are also used.
