Examiner presses thumbs over carpal tunnel and holds pressure for 30 seconds. [2] An onset of pain or paresthesia in the median nerve distribution within 30 seconds is a positive result of the test. [1]
By compressing the median nerve within the carpal tunnel, characteristic symptoms (such as burning, tingling or numb sensation over the thumb, index, middle and ring fingers) convey a positive test result and suggest carpal tunnel syndrome. Because not all individuals will draw the lumbricals into the carpal tunnel with this maneuver, this test ...

Carpal tunnel syndrome usually has no known cause, but there are environmental and medical risk factors associated with the condition. [1] [6] CTS can affect both wrists.
Carpal tunnel syndrome (CTS) is caused by compression of the median nerve as it passes under the carpal tunnel. [11] Nerve conduction velocity tests through the hand are used to diagnosis CTS. Physical diagnostic tests include the Phalen maneuver or Phalen test and Tinel's sign. To relieve symptoms, patients may describe a motion similar to ...
Anterior interosseous syndrome is a medical condition in which damage to the anterior interosseous nerve (AIN), a distal motor and sensory branch of the median nerve, classically with severe weakness of the pincer movement of the thumb and index finger, and can cause transient pain in the wrist (the terminal, sensory branch of the AIN innervates the bones of the carpal tunnel).
