There are established normals ranges for things such as blood pressure and blood sugar levels. If you get tested and the results fall outside of these ranges than you are able to know that things are abnormal.
In the Atlas Bone (C1), there is normal and abnormal alignment. When the atlas alignment shifts even half a millimeter, it will cause Neural Abnormalities in the body. Neural Abnormalities occurs because the Atlas Misalignment is going to pressure on the brainstem which is going to cause your nervous system to be imbalanced. When the nervous system is imbalanced, your body won't be able to work and function at its highest capacity.
The Primary Condition that we work with is called Neural Abnormalities.
