Neuroman,

Thanks for the thorough reply. Just to clarify, its a static weight bearing test right? Also have you found that changes in alignment during the test are linked with the reproduction production of LBP symptoms - I ask this given that a change in alignment post-Rx seems to relate to improvement in symptoms - from what I gather anyway? Or is something that you see over time?

I look forward to reading the paper/s when they come to hand and until then I will trial the Ax tool on my LBP patients - out of interest any subgroups/classifications of NSLBP that you have found this tool to be most useful. e.g. either from McKenzie/O'Sullivan/Lee classifications etc? Or perhaps this will serve as yet another classification system.

Also what is the title of the test as it will be keyworded in upcoming research?

On face value it sounds like it may be useful, though I'm still a little skeptical when it comes to using/relying on alignment/asymmetry in the human body to correlate with musculoskeletal pain - particularly when it relates to non-specific LBP. Skepticism, as you can appreciate comes hand in hand with physio.

Is there a place for the use of a saggital plane LL position/movement within the test to simulate a more functional WB position?

Cheers for your input.
