FABER Test
The FABER or Patrick Test tests for SI joint pathology or intraarticular hip pathology. To perform this test, keep one leg in extension; with the other leg, flex, abduct, and externally rotate the hip so that the ankle is placed above the patella of the opposite leg. Press downwards simultaneously on the knee and on the ASIS of the contralateral side. Low back pain is a positive test for SI joint pathology; anterior groin pain is a positive test for intraarticular hip pathology.
