Recommended physical examination of FAI as described by Yen et al26
| Examination position | Visual inspection | Test 1 | Test 2 | Test 3 | Test 4 | Test 5 |
|---|---|---|---|---|---|---|
| Standing | Patient's posture will reveal protective manoeuvers to alleviate pressure on hip: slightly flexed hip and ipsilateral knee. Shoulder height and height of iliac crest for leg length issues. | Gait | Adam's forward bending | Trendelenburg Test | Clinical popping, snapping or clicking | |
| Seated | Patient will slouch and lean in the direction of the unaffected hip to lessen the degree of flexion to the affected side. | Straight leg test | Babinski test | Internal and external rotation measurements | Ludloff | Deep tendon reflexes of Achilles and patella |
| Supine | Assess musculature of the lower extremity visually and by measured thigh circumference. Differences in circumference in the affected and non-affected side may reflect chronic conditions and muscle atrophy. | Straight leg test | FADDIR test and Scour test | Thomas test | Patrick or FABER test | McCarthy test |
| Lateral | Patient lies on unaffected hip in the lateral decubitus position. Muscle tone should be assessed; if a large gluteus medius tear is present, the leg cannot lift. | Tinel sign | Snapping of the iliotibial band: bicycle test | Ober test | FADIR test | |
| Prone | Examines pathology that can be related to or is independent of the hip joint. | Modified Thomas test | Ely test |
FABER, flexion, abduction, external rotation FADDIR, flexion, adduction, internal rotation; FADIR, flexion, adduction, internal rotation; FAI, femoroacetabular impingement.
