Pain with forceful internal rotation of the flexed thigh (Freiberg maneuver), abduction of the affected leg while sitting (Pace maneuver), raising of the knee several centimeters off the table while lying on a table on the side of the unaffected leg (Beatty maneuver), or pressure into the buttocks where the sciatic nerve crosses the piriformis muscle while the patient slowly bends to the floor (Mirkin test) is diagnostic.
