To All:
I would like to add that repeatability and inter-tester results ARE important ONLY IF THE TEST IS UNQUESTIONABLY RELIABLE. The stork test or standingSIJ test with hip flexion or torso flexion fails in that the same landmarks do a different movement in the same test with hip ABD.
My question is: How can this supposed "stuck" SIJ or "fixation of" the SIJ move apart in the second test if the first is accurate???
Inter-tester repeatability is important when the test is verifiable, accurate and has no loop holes. It is a scientific tool.
Please note that some have missed this part of the assessment.
My best to all,
Neduromuscular.
