NPTE Complete Practice Exam 2026 – Prepare for Your Test

The FADDIR test is specifically designed to assess impingement and labral pathology of the hip joint. During the test, the involved leg is moved into flexion, internal rotation, and adduction. This particular combination of movements helps to compress structures within the hip joint, potentially reproducing symptoms associated with labral tears or femoral acetabular impingement.

When the hip is flexed, it brings the femur closer to the pelvis, while internal rotation places additional stress on the anterior structures of the hip joint. Adduction further narrows the space within the joint. Together, these movements can provoke pain or discomfort if there is an underlying pathology, making this test clinically relevant for physical therapists assessing hip conditions.

This understanding of the FADDIR test's mechanics supports the conclusion that flexion, internal rotation, and adduction are the correct motions of the involved leg during the assessment, as they specifically target the areas of concern for diagnosing hip pathologies.
