What are the fixations for a PRS?

In this pattern, the fixation is the posture that best reproduces the symptoms and stabilizes the involved spinal segment. For a left-sided PRS pattern, that posture is extension combined with rotation to the left and lateral flexion to the left. Extending the spine with leftward rotation and leftward bending places the vertebral segments in the position most consistent with the left-sided restriction and loading described by PRS, making it the most appropriate fixation. The other options mix flexion instead of extension or rotate/bend to the opposite side, which would not match the left-sided extension-rotation-left lateral bend pattern that defines this fixation.
