A clear conceptual differentiation between structural and functional aspects of the body allows us to make clearer statements about its structural state. With the block model as our reference, we can analyze the relative position of the major body segments, i.e. show in which direction these segments deviate from normal. Tilt and shift of the pelvic segment in the sagittal plane determine distinctive patterns in the front-to-back dimension; side-tilt and side-shift do the same for the left/right dimension. Rotation around the vertical axis reveals the so-called “standard rotation,” while examining deviations upward and downward along this axis leads to the point of view of structural dynamics. The results of such an analysis provide a rational background for bringing the body more toward normal. This system provides a framework for dealing with local concerns while keeping the whole in mind.
