Durkan's test

Durkan's test
Purposediagnose carpal tunnel syndrome.

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.[1]

Process

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]

Accuracy

In studies of diagnostic accuracy, the sensitivity of Durkan's test ranged from 87% to 91% and its specificity from 90% to 95%.[2][3]

Comparison

Durkan's test is more sensitive than Tinel's sign and Phalen maneuver.[4]
