I’ve done pretty much every test for IR that I was able to find.
My preference was the one you suggested: lying supine, test leg hip flexed to 90, other leg in extension. Interestingly the result was if I did this with a partner (usually a trained physio as I know a few) was about 10 degrees because they would stop at the point of impingement. But if I conduct the test with active flexibility (I.e myself) I can sometimes get 20-30.
If I conduct the test actively sitting on a bench with hips in flexion 90 I found I can usually get to 10-20
If I conduct the test actively lying prone with hips in extension I found I can usually get to 20-25
I’ll take some pictures if that helps.
