According to Fryette's second principle, in non-neutral mechanics, how do sidebending and rotation behave?

  1. They are opposite

  2. They are the same

  3. They do not occur

  4. They increase distance

The correct answer is: They are the same

Fryette's second principle states that in non-neutral mechanics of the spine, sidebending and rotation occur in the same direction. This principle is particularly applicable when the vertebra is in a non-neutral position, meaning it is either flexed or extended. In such a case, when the spine bends to one side, the vertebrae will also rotate toward the same side. This is a crucial concept in osteopathic manipulative treatment and understanding spinal biomechanics, as it informs practitioners about how to assess and address somatic dysfunctions in patients. Recognizing that both movements occur together allows for more effective management of musculoskeletal issues, as correctly diagnosing and treating these positional relationships can lead to better outcomes in patient care.
