Phalen sign
The Phalen's sign (also Phalen's test , English : Phalen's maneuver , Phalen's test ) is a clinical sign from neurology. Even in the early stages of a carpal tunnel syndrome , prolonged, terminal hand flexion leads to dysesthesia in the supply area of the median nerve . The sign was described by the American orthopedic surgeon George Phalen (1911-1998) in 1948. Although its sensitivity is superior to that of the Hoffmann-Tinel sign , the specificity of both signs for diagnosing carpal tunnel syndrome is relatively low.
