Has anyone yet showed that TA activity is more prevalent in non-back pain suffers than in those with back pain?

I have worked clinically with all type of back pain and was part of the group who co-research and published the UK's 2000 guidelines on the treatment of occupational low back pain. This was an 18 month effort reviewing 3,500 clinical trials, many double blind RCT's. I have not seen anything more than anecdotal evidence about the assume "huge" importance of TA. I would think that the serratus, internal/external obliques, piriformis activity, psoas activity could be given just as much hype. In fact a few simple rotational, flexion and extension back exercises seem to fix the majority of mechanical pain. Are they only working on TA? It's nice to look at the activity with funky technology but how are the ear muscles functioning at the same time? probably not well? Maybe we should train them and back pain would reduce.

I for one appreciate the work on TA but feel it is WAY WAY WAY to isolated in its approach and after all we are a mobile being. We need to move about and our skeletal system is not held together solely by a sustained TA contraction.

Please do comment and or offer studies of relevance.
