a-f. Hip impingement tests: AIMT (a) The examiner brings the hip into 90° flexion and then moves the hip into medial rotation and adduction. FADIR (b) The examiner brings the hip into maximal flexion, medial rotation and adduction. FABER (c) the examined leg is placed with the foot just proximal to the contralateral knee joint and the hip is brought into a combined flexion, abduction and external rotation. The examiner places a hand on the contralateral side of the pelvis to minimize pelvic rotation. DEXRIT (d) and DIRIT (e) the patient is asked to hold the contralateral hip in more than 90° flexion. The examiner then brings the hip into approximately 90° flexion and moves the hip through a wide arc of extension, abduction and external rotation (DEXRIT) or extension, adduction and internal rotation (DIRIT). PRIMT (f) supine position with the patient lying at the edge of the examining table. Both hips are brought into flexion and the patient is instructed to keep the contralateral hip in flexion while the examined hip is brought into extension, abduction and lateral rotation
