Phalen's maneuver
Phalen's maneuver [fa´lenz] to detect carpal tunnel syndrome, the size of the carpal tunnel is reduced by flexion (or extension) of the affected wrist for 30 to 60 seconds, or by inflating a sphygmomanometer cuff around the involved hand to a point between diastolic and systolic pressure for 30 to 60 seconds. Pain or paresthesias occur along the distribution of the median nerve when the patient has carpal tunnel syndrome. Pain and/or paresthesias are produced in the distribution of the median nerve when the hands are held in flexion for 30 to 60 seconds. From Goldman and Bennett, 2000. |
