John, I have looked carefully through this article and cannot find the words "stability" or "instability" anywhere. Really. I find "good postural alignment" and "alignment as a contributor to pain problems" but nothing, nothing about working to "stabilize" anything. Sahrmann says: "Sensitive measurement tools, capable of detecting significant variations in alignment of a segment or two from the normal range, are going to be necessary to assess the relationship of alignment to pain." Apparently she doesn't think that the imaging we currently have is sensitive enough to detect the thing she's looking for. Doesn't this sound kind of strange to you? How is this related to the stability of anything? It seems clearer each time I read this that Dr. Sahrmann's primary concern in evaluation is the *position* of the system and how we might work to discover how misalignment leads to pain. I can't see how this jives with the dynamic stabilization concept as you suggest. As for whether the criticism of that work has been responsibly done by responsible people, I think I'll let Mel Siff address that charge. I appreciate your sticking with this John. Anyone else out there? Barrett L. Dorko, P.T. <http://barrettdorko.com>
