Patrick's test, also known as the FABER (flexion, abduction, external rotation) test, is a diagnostic tool used to evaluate hip pain and mobility. However, there are other synonymous tests that can be used in conjunction with Patrick's test to provide a more comprehensive assessment. These include the Thomas test, which measures hip flexor and iliopsoas muscle length, the Ober test for iliotibial band tightness, and the Piriformis test to assess for piriformis syndrome. Other tests such as the Trendelenburg test and the Scour test can also be useful in evaluating hip pain and mobility. Using a combination of these tests can help healthcare professionals accurately diagnose and treat hip conditions.
