My dad started with a spinal blueprint. The spinal blueprint consists of standing and seated, front view and side view full spine x-rays. He would then measure 50 measurements on the spine and those are the key angles, the landmarks of the spine. And then he began to realize that each area of the spine indicated a different psycho genetic issue. So over 30 years or so, we've really begun to identify these core underlying issues.
