Cranial Evaluation and Treatment Practice Test 2026 – Complete Exam Prep Guide

Cranial strains come from how the sphenobasilar joint moves when trauma disturbs the cranial mechanism. The patterns are named by the direction in which the SBS moves: vertical strains move the SBS up or down, lateral strains move it side-to-side, torsions rotate the bones about the SBS, and sidebending-rotations combine bending and rotation. In the sequence used in this context, the trauma pattern listed as number two corresponds to a right lateral strain. That means the sphenoid and occiput rotate in opposite directions with the SBS shifted toward the right, producing a rightward lateral displacement. Clinically this shows up as rightward asymmetry and a restriction pattern consistent with a right lateral strain. The other options describe different patterns: an inferior vertical strain shifts along the vertical axis, a left lateral strain is the left-side counterpart, and a right sidebending-rotation is a distinct pattern combining lateral bend and rotation to the right.
