Reverse Phalen's test. This test is performed by having the patient maintain full wrist and finger extension for two minutes. The reverse Phalen's test significantly increases pressure in the carpal tunnel within 10 seconds of the change in wrist posture and the carpal tunnel pressure has the tendency to increase throughout the test's duration.
Durkan's test is a medical procedure to diagnose a patient with carpal tunnel syndrome. It is a new variation of Tinel's sign that was proposed by JA Durkan in 1991 ...
Carpal tunnel syndrome (CTS) is a nerve compression syndrome associated with the collected signs and symptoms of compression of the median nerve at the carpal tunnel in the wrist. 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.

Restricting wrist motion eliminates the repetitive movement and tension overload in the carpal tunnel. This gives the tendon sheaths a chance to heal, reducing swelling, which then may decrease the pressure on the median nerve. [citation needed] Splints also aim to keep the wrist at a certain angle to decrease pressure within the carpal tunnel ...
The modified Allen's test is also performed prior to heart bypass surgery. The radial artery is occasionally used as a conduit for bypass surgery, and its patency lasts longer in comparison to the saphenous veins. Prior to heart bypass surgery, the test is performed to assess the suitability of the radial artery to be used as a conduit.
In the human body, the carpal tunnel or carpal canal is a flattened body cavity on the flexor (palmar/volar) side of the wrist, bounded by the carpal bones and flexor retinaculum. It forms the passageway that transmits the median nerve and the tendons of the extrinsic flexor muscles of the hand from the forearm to the hand . [ 1 ]
The compression of the median nerve within the carpal canal of the wrist and the progression of symptoms resulting from this entrapment is known as carpal tunnel syndrome (CTS). Nerve conduction studies have been used as a control electrophysiological method in the development of better CTS diagnostic techniques. [9]
