Assessing C1-C2

To perform this test, maximally flex the cervical spine followed by maximal rotation either left or right. Flexion is thought to lock out all vertebrae below allowing for rotation at C1-C2 only. The difficulty with the flexion-rotation test is maintaining flexion while maximally rotating the upper cervical spine. From my experience, there is a ...
