I do not understand your statement:

"I'm having trouble accepting your critique of Static Back for various reasons"

In light of your statement:

"I won't deny that the floor flattens my thoracic spine for a short period of time, but there are lots of exercises that put your body in a non-natural position for a short time. Examples include Brugger relief pose, sternal positional Swiss ball release, all yoga poses (hehe), pull ups, etc. You would never do any of those for very long. You could analyze the details of any of them and say "well that's not natural" and "it stresses parts of your body".

which exactly makes the same point.

As for this:

Is that not true for most exercises?"

the answer is many but I do not know about "most". However, what is the point of the question?

You then make these two statements:

"I feel my spine elongate when I do static back for 10 mins. I have to make an adjustment part way through as a result."

"I've been getting good results regardless of this or that explanation."

Which indicates you are still having problems though you feel they are getting better.

I completely understand and that situation is covered by my previous statement:

"It might feel good for some because it will temporarily reduce the amount of mechanical stress on one area by worsening the condition and forcing the stress to some other area. This gives the apparentcy an improvement however, it is not an improvement just a change and almost always for the worse. The end result will either be a return to the previous configuration with its attendant symptoms and or pains or a change to something worse mechanically which may result in immediate or later symptoms that are different."

That statement notes the uncomfortableness you note that you have to adjust your position to handle, as well as the temporary relief you note as the body is shifted to a different position and the mechanical stress is changed to elsewhere, as well as the return of the symptoms as the body again shifts to the previous position as it tries to reestablish the compensation for the original problem.

People often have a problem with my statement that if a correction is made, a true correction of body mechanics is made, the problems and its symptoms just disappear and do not need constant re treatment or handling because they do not usually experience that.

They most often experience the changes you noted in your post and evaluate that as improvement rather than just temporary change.

With Advanced BioStructural Correction™ a particular symptom will often continue until the problem the is at the basis of that symptom is handled and then it just disappears.
