Which term describes a cranial strain pattern we see as Left Sidebending Rotation?

• A. Left Sidebending Rotation
• B. Right Sidebending Rotation
• C. Compression Dysfunction
• D. Left Torsion

Answer: (A)

The main idea here is how cranial strains are named. A sidebending-rotation pattern is described by the direction the SBS is sidebent and rotated. When you see a pattern described as Left Sidebending Rotation, it means the spheno-occipital region is moved to the left (sidebent left) and rotated to the left as well. That exact description is the term that fits the pattern, so the term itself is the best answer. This differs from other patterns: a Right Sidebending Rotation would be the opposite direction, a compression dysfunction involves a generalized compressive state rather than a leftward bend and leftward rotation, and Left Torsion describes a torsional pattern where the sphenoid and occiput rotate in opposite directions around the SBS, not the same-direction left-side movements of Left Sidebending Rotation.
