Other Names
- Modified External De-rotation Test
- Resisted External Derotation Test (REDT)
- External Derotation Test
- Hip External Derotation Test
- Resisted Derotation Test
- Lequesne External Derotation Test
Purpose
- To evaluate the cause of hip pain
Description
Classic Description
- The patient is supine
- The hip and knee on the affected side are both flexed 90°, and then the hip is externally rotated.
- The patient is then asked to internally rotate the thigh back to a neutral position while the examiner resists
- Positive test
- Trochanteric pain
Modification
- Patient lies supine.
- Hip flexed to 45° and maximally externally rotated
- Knee flexed to 90°
- Examiner stabilizes the lateral knee and resists at the medial ankle
- Patient internally rotates the hip against resistance
- Positive test
- Lateral hip pain and/or weakness compared with the contralateral side

- Greater Trochanteric Pain Syndrome
- Gluteal Tendon Tear
