Pushing on the discs or the vertebral segments and so the discs.. because that's what I have had much of the time however gently as I am a small person w/known disc probs/surgeries and my weight was like 102 at the time of the surgeries (115 or so now). So the right amount of pressure is used when it's a very experienced person who knows how to work w/each individual.

I don't know if I answered the question you were actually asking... btw I had alot of sacroiliac work done as well as I used to have tons of probs w/sacroiliac joint dysfunction or so all the PTs said when working on me.

Eventually you sort of learn to release yourself .. or it seemed that way to me and I don't know if that's because I have less pain so I carry myself much looser or all the combinations of whatever worked for me so I am much less "tight" and unstable these days.

My L5S1 did autofuse as something like 28 years.. so I think that helped quite abit w/my spine seeming more stable.
