Looking for a more detailed discussion of the science behind upper cervical care?
There is a logical chain of arguments that support specific upper cervical work. This chain is supported by some evidence at each link, with the evidence for some aspects being stronger than others. Given the anatomical, biomechanical and neurological complexity of the upper cervical spine, specific upper cervical work is an appropriate approach to adjust the upper cervical subluxation.
Dr. Kirk Eriksen,Upper Cervical Researcher, take from notes from his position paper, as featured on the The Upper Cervical Blog.
