Which statement accurately describes oblique axis sacral dysfunction?

• A. It is physiological
• B. It is non-physiological
• C. It is never seen
• D. It is not related to sacral motion

Answer: (A)

Oblique axis motion is a normal part of how the sacrum moves with the pelvis. There are two oblique axes through which the sacrum can rotate as the ilia tilt and rotate during activities like walking. This diagonal rotation pattern is a standard, physiological mechanism, not a pathological one. So a dysfunction described along an oblique axis reflects a variation within normal sacral biomechanics, rather than a non-physiological problem. That’s why the statement describing oblique axis sacral dysfunction as physiological is the best choice. The other options contradict well-established sacral motion: oblique-axis movements are real and related to sacral motion, and this motion isn’t something that would be never seen or inherently non-physiological.
