This is la no brainier to me. when there is a log jam of information from the brain to the body all kinds of problems will occur.The body will over time slowly  twist,and bend loosing the healthy curve of the spine.  This is why early detection of an imbalance in the spine is paramount. upper cervical specific only care doctors scientific objective instrumentation is the only way to detect such imbalance. www.upcspine.com,and wwwthespecific.com are two good sites Erin Elster is good too. She does knee chest technique.She adjusts on the posterior arch of the atlas. A plethora of problems can be helped,but prevention and, periodic monitoring of the structure and nervious system of the body is the best thing for over all health.

Please avoid cavitating chiropractors.
