• Comment: One source if not enough to show notability. It's not clear if the source is primary, i.e. did Buckup come up with it. Lastly, there is a copy of the book online here and a search results zero hits for "Knap", and I see no mention in the contents in the hip section where it mentions Fabere/Patrick KylieTastic (talk) 11:22, 6 September 2024 (UTC)

Knap's test or Knap sign is performed to evaluate possible pathology of the hip joint or the sacroiliac joint when other tests may not be positive due too low sensitivity.

Test performance

edit

The test is performed while lying on the back by having the tested leg flexed and putting the other leg's foot above its knee and pushing the rotated knee straight along the flexed leg. The test is considered positive when the tested leg hip goes up automatically showing dysfunction in the pelvis.

The test differs from FABER or Patrick's test by having the tested leg flexed instead of being straight. The other difference is a hip raise or possible back pain instead of a groin pain. [1]
