Hi Neuromuscular,

My friend, please try a different approach with Ginger - to me, it would seem you are trying to get him to agree by taunting, badgering and basically insulting him - all of which tends to cause anyone to close up to your ideas.

In defence of the stork test, a relatively recent study by Hungerford et al demonstrated that the stork test had inter-tester reliability on a Yes/No system.

I have no doubt that you both get get good results.

In defence of your APAS, to my mind, it is like a stork test in a different plane of motion (except both feet are on the ground!).

My difficulty with your test (APAS) is that you do not reference the sacrum therefore you cannot truly test each Wikipedia reference-linkSIJ joint. For example, if i were to discover that the ASIS and PSIS of the left innominate is anterior and the ASIS and PSIS of the right innominate are posterior during increased ABD stance positions, then it is not proof of the SIJ moving but quite possible that the rotation of the whole pelvis is rotating on the hips...

If i may be so bold as to suggest the following...please remember the wise words fo Abraham Lincoln - "A drop of honey catches more flies than a gallon of gall."

One of the ways many people improve their ideas, systems and tests is to try to tear them down - what are the limitations of your test? What alternative explanations are there to explain the apparent test results?

I am thinking of the Disney system where they have (apparently) 3 rooms...
1. Ideas room - here everything is set up to foster idea generation and it is not allowed to point out flaws but to try promote the idea as far as possible.
2. Flaws room (i have no idea what they really call these rooms) - here they set out to destroy all ideas that come through - it is this refining by fire and sending back to the drawing board which produces their best ideas
3. Make it happen room - once an idea stands up, they make it happen.

If you cannot see any limitations to your test, i would suggest you are too close to it and not objective enough. Every test, every system, every idea has its limitations.

Please post your thoughts on what alternative explanations people have provided once they have tried your test...

My very best to you Neuromuscular...
