During OA Decompression, what pressure is applied between C1 and the occiput?

Explanation:
OA decompression relies on a gentle caudal pressure applied between the occiput and the atlas (C1). This downward traction creates a slight distraction at the OA joint, allowing the occiput and C1 to separate and freeing space at the junction. The goal is to relieve compression at the foramen magnum and support the cranial motion pattern, not to push the bones toward each other or twist them. An anterior, lateral, or rotational torque would not produce the same decompressive effect and could misalign the joint or introduce unwanted forces.
