Patient supine. Sideglide mid cervical spine. Keep the wrists extended, with the hands cupped around the neck. Add a little tilt at the end of the movement, makes it easier to feel what is going on. In side gliding to the right, you check for movement down and back on the left, up and forward on the right. If you feel restrictions, immediately check side gliding at that level in extension and flexion. Testing in extension means just picking up the slack, creating a nice fulcrum, Testing in flexion means semi flexion, not full flexion.
