Specific Tests
Physicians can use specific tests to try to produce the symptoms of carpal tunnel syndrome.
The Tinel Test
In the Tinel test, the doctor taps on or presses on the median nerve in the patient's wrist. The test is positive when tingling in the fingers or a resultant shock-like sensation occurs.
The Phalen Test
The Phalen, or wrist-flexion, test involves having the patient hold his or her forearms upright by pointing the fingers down and pressing the backs of the hands together.
