Phalen

Phalen's maneuver or Phalen's test is a diagnostic test used in the field of medicine, specifically in the diagnosis of Carpal Tunnel Syndrome. The test was named after the American orthopedic surgeon, George S. Phalen.

Procedure

The Phalen's maneuver is performed by having the patient flex their wrists and press the backs of their hands against each other for about one minute. This position compresses the Median Nerve at the wrist and can cause symptoms in individuals with Carpal Tunnel Syndrome.

Interpretation

A positive Phalen's test is one that results in tingling or numbness in the fingers within 60 seconds. The test is considered positive if the patient experiences symptoms similar to those they have been complaining about, usually numbness or tingling in the thumb, index finger, middle finger, and the lateral half of the ring finger.

Reliability

The reliability of Phalen's test varies among studies, but it is generally considered less sensitive but more specific than the Tinel's sign.
