Execution
- 1Position the patient supine.
- 2Move the test hip to approximately 90 degrees of flexion.
- 3Add hip adduction and external rotation to place compressive and tensile load on the lateral hip tendons.
- 4Record whether lateral hip pain is reproduced in the passive FADER position.
- 5Add resistance to internal rotation for the FADER-R version and record pain response.
Positive outcome
Reproduction of familiar lateral hip pain is positive. Passive FADER tests compressive and tensile sensitivity, while FADER-R adds active contraction against resistance. Groin pain or posterior pain should not be counted as a gluteal tendinopathy positive.
Studies
| Study | Reliability | Sn | Sp | LR+ | LR− |
|---|---|---|---|---|---|
| Grimaldi et al. (2017) | NA | 30 | 86.7 | 2.25 | 0.81 |
| Grimaldi et al. (2017) — FADER-R | NA | 44 | 92 | 5.50 | 0.61 |
CommentGrimaldi’s MRI-confirmed study supports better specificity for resisted variants than passive pain provocation alone. The test is most useful when it reproduces exact lateral hip pain and agrees with palpation or single-leg stance. It should not be used alone because sensitivity is limited.
