The investigations into reflex analysis of the cranium were based on the work of Dr. H. Gilet and Dr. M. B. DeJarnette. In Dr. Gillet’s “Belgian Research Notes” of the early 60s, he revealed that atlas fixations commonly occur as secondary fixations to sacroiliac subluxations. Dr. DeJarnette discussed an association of sacral fixations with cranial faults and called them faults in the cranial-sacral respiratory mechanism. This article describes a relatively simple approach to cranial analysis, which requires no cranial motion palpation, muscle testing or other vague signs, such as the cough test. It might be necessary to sharpen your cervical motion palpation, however sacral reflexes can also be used which is presented.
