Revamping a possible archaic view of normal cranial physiological biodynamics
is a challenging undertaking. New ideas lie fragile for years awaiting the
slow accumulation of evidence. This article presents substantial research
answering the questions: (1) Is it possible for the cranial bones to move?
(2) Do intracranial pressure changes actually translate into cranial motion?
(3) Are there pressure changes of cerebrospinal fluid occurring
intracranially due to vascular, pulmonary, and other theorized pulse waves?
(4) What can interfere with the transmission of these pressure waves? (5)
What could be the consequences of increased and/or decreased cranial motion
to the health of the body?
The author presents literature noting that dural tension and/or
brain/spinal cord tension reflecting in the neural substance, nerves and
associated blood vessels could well lead to changes of a pathological nature.
This could be separate or could be in conjunction with associated CSF buildup
of catabolites and resultant patho-physiological changes. The effect of
cranial bone stasis or tension is clinically alleviated through gentle subtle
manipulations of the cranial bones. The treatment is focused towards
obtaining relaxation of the soft tissues of the brain and spinal cord in
situ, through the dural extension into the sutures and cranial bones.
