Now suppose that the muscle between the left transverse processes is normal and the muscles between the right transverse processes is hypertonic. We see that a simulated hypertonic right lateral intertransversarius muscle results in a restrictive barrier to flexion, left rotation, and left sidebending). You can see that both facets are still able to close fully, but only the left facet is able to open fully. The right facet is prevented from opening fully because of the increased tension within the muscle between the right transverse processes. In terms of the postional diagnosis (remember that the positional diagnosis describes where the structure that we are examining wants to go), we would say that this segment is extended, right rotated, and right sidebent. In terms of the motion restriction diagnosis (remember that the motion restriction diagnosis describes where the structure that we are examining does not want to go), we would say that this segment resists flexion, left rotation, and left sidebending.
