New research: No such thing as "stuck" SI joint

[neuromuscular]

hmm... raises questions as to muscular slings and muscle patterning

Thank you.

You are right.

The test to prove this is as follows:

Landmarkws: ASIS to ASIS, PSIS to PSIS, ASIS to PSIS (R&L).

From standing closed leg position have the patient do hip abduction for each landmarking at 15 cm foot positions to the maximum for the patient.

The following statistics have been obtained:

Patients with no back pain: Pelvic angles near anatomical neutral throughout test range.

Back Pain:

Only 10% have bilaterally equal pelvic angles either in anterior or posterior rotation.

90% have differing pelvic angles or angles which increase in difference as the hip abduction proceeds.

60% have right anterior left posterior
20% have right anterior left neutral
20% have right in greater rotation than left.

See what your statistics are.

This was in over 1,000 patients.

A true stuck SI joint was not seen.

To All:

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

The comparison test done to challenge the popular ubiquitous standing SIJ 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.

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 standing SIJ 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.
