Our vestibular system is a component in our balance. The head weight about 12 pounds or more. That's like a bowling ball. The vestibular system seeks equalibrium and it uses the muscle in the spine to do it. It's like a computer in a jet fighter. It is making many adjustment per second and it keeps trying to keep us balanced. That is why we get pain and spasms in what looks like on imaging is a structurally sound spine. A brand new car out of alignment will drive like crap and an old junker with worn parts will drive OK.
