To All:

Let us be sure that we are all on the "same page".

The comparison test done to challenge the popular ubiquitous standing Wikipedia reference-linkSIJ test or "stork" test is as foolows:

Step one:

Do standard SIJ test with hip flexion or torso flexion or both.
Patient standing. Practitioner landmarks the PSIS to sacrum from the posterior. Practitioner maps the SIJ of the PSIS to sacrum as hip flexion and subsequently the torso flexion is performed by the patient.

Step two:

Patient standing. Practitioner posterior to the patient landmarks the PSIS to sacrum. Practitioner maps the PSIS to sacrum as the patient does hip ABD to the following positions: 25 cm, 50 cm, 75 cm, 100 cm, to the ability of the patient to perform hip ABD. Practitioner maps the PSIS to sacrum through the entire hip ABD.

Note the positions of the PSIS to sacrum in each phase of the tests. Note any differences. What is your conclusion???

This IS comparing "apples to apples".

Do the APAS test to find out if you are missing other pertentant information on your patient/client.
