- FAIR Test
- Piriformis Test
- FADDIR
- Flexion, internal rotation test
- Anterior Impingement Test
Purpose
- Evaluate Piriformis muscle and other causes of hip pain
Description
- The patient can be either supine or laying on their side
- Passively move their hip into 90° of flexion, while adducting and internally rotating
- Positive test

- Note the patient may also feel anterior thigh pain from hip pathology
- Alternative approach is flexion, internal rotation without adduction
Modified FADIR

Pathology
- Piriformis Syndrome
- Femoral Acetabular Impingement
- Avascular Necrosis of the Hip
- Hip Osteoarthritis
- Acetabular Labral Tear
- Snapping Hip Syndrome
