I think I have a quick question regarding a chessboard interpretation. I've recently had a series of narrow ISA individuals whose external rotation (ER) measures are very challenging. They seem to have potential for significant ER, but upon closer examination, the movement appears more focused on internal rotation (IR). For this question, assuming the right IR is less than the left, I'm considering primarily the hip. For an individual to reach a point where right IR is less than left, would this be due to the orientation of the left innominate into anti-orientation, or the one-bar spine turning away? Presumably, their center of gravity should have shifted forward on the left before moving right, causing initial loss of left IR. So, I'm wondering how they return to a state where left IR is greater than right.
