This is the second of a series of abstracts of published articles relating to
Sacro Occipital Technique and Cranial Manipulation. Please use these for
educating insurance companies, the judiciary, the legislature, the colleges
and the interested public.

Cooperstein, Robert, Sacro Occipital Technique. Journal of Chiropractic
Technique , August 1996, Vol. 8, No. 3: pp. 125-31.

This paper was commissioned to be written, by the ACA Council on Technique in
conjunction with its Advisory Panel. The article discusses the history,
scientific basis, and clinical techniques used by practitioners of Sacro
Occipital Technique. Originally developed by Major Bertrand DeJarnette as an
outgrowth of a combination of chiropractic and osteopathic methodologies, it
has become one of the more frequently used chiropractic procedures. The
keystone to diagnosis within this system is the ability to place patients
into one of three categories. Other diagnostic and therapeutic
considerations are discussed as well.

Blum, Charles L., The Effect of Movement, Stress and Mechanoelectric
Activity Within the Cranial Matrix. International Journal of Orthodontics ,
Spring 1987, Vol. 25, No., 1-2, pp. 6-14.

This study presents substantial research supporting the premise that:
(1) Cranial sutures and bones are capable of flexibility and slight
movement. (2) Mechanical stresses can affect the sutures on a short-term
basis. (3) Mechanical stresses can affect the sutures on a long-term basis.
(4) An interrelationship exists between cranial sutures and the structures
transmitting mechanical forces; this relationship has a matrix/holographic
organization. (5) Mechanical stresses within the cranial bones and sutures
are capable of creating a piezoelectric effect. This piezoelectric effect is
of a magnitude sufficient to create changes within the associated cranial
bones and soft tissues to affect enzymatic changes, osteoblastic/osteoclastic
activity and neuroelectric dynamics.

The author concluded that in light of the advances in orthodontics,
temporomandibular joint treatment, and cranial manipulative therapy, we must
view cranial motion as part of a dynamic and kinetic, physiological, cranial
matrix. The ability for cranial bones to move, or not move, plays a part in
the transmission of stress within the cranium and could have far reaching
effects.

Getzoff, Harvey & Gregory, Thomas M., Chiropractic Sacro-Occipital Technique
Treatment of Arthrogryposis Multiplex Congenita. Journal of Chiropractic
Technique , May 1996, Vol. 8, No. 2, pp. 83-7.

The author's objective was to present a case of chiropractic treatment of
arthrogryposis multiplex congenita (AMC). The case involved a 6 year-old boy
diagnosed with AMC evidenced by severe generalized locomotor disability,
including the inability to bend over to tie his shoes , as well as
reoccurring kidney infections. His prior treatment options included only
orthopedic surgery and antibiotic therapy. His parents instead chose to
begin chiropractic care and continue with antibiotic therapy in an effort to
increase his level of physical ability.

The patient received 26 chiropractic treatments using Sacro Occipital
Technique (SOT) protocols over a period of 9 months, after which he could
bend over to tie his shoes. In addition, he learned to ride a bicycle
without training wheels, could swim part of the way across a pool unaided,
and presented a greatly improved physical demeanor. SOT chiropractic
treatment demonstrated effectiveness in improving general physical ability
and quality of life for a child suffering from AMC

Flanagan, Michael F., The Relationship Between CSF and Fluid Dynamics in the
Neural Canal. Journal of Manipulative and Physiological Therapeutics,
December 1988, Vol. 11, No. 6, pp. 489-92.

This study determined that there is a relationship between fluid dynamics in
the neural canal and cranial vault. This relationship can be affected by
posture, respiration and pathology. In addition, several chiropractic
disciplines have advocated that axial skeletal improprieties may also affect
fluid dynamics in the canal and vault. This paper reviews literature
pertinent to these issues. The information it contains is relevant to those
disciplines that attempt to manipulate fluid dynamics in the canal and vault,
as well as to those that treat neurological disorders.

Blum, Charles L., Biodynamics of the Cranium: A Survey. The Journal of
Craniomandibular Practice , March/May 1985, Vol. 3, No. 2, pp. 164-71.

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.

Norton, J. M., A Tissue Pressure Model for Palpatory Perception of the
Cranial Rhythmic Impulse. Journal of the American Osteopathic Association ,
October 1991, Vol. 91, No. 10, pp. 975-7, 980, 983-4.

In this study a tissue pressure model was developed to provide a possible
physiologic basis for the manifestation of the cranial rhythmic impulse
(CRI). The model assumes that the sensation described as the CRI is related
to activation of slowly adapting cutaneous mechanoreceptors by tissue
pressures of both the examiner and the subject, and that the sources of
change in these tissue pressures are the combined respiratory and
cardiovascular rhythms of both examiner and subject. the model generates
rhythmic impulses with patterns similar to those reported for the CRI. Also,
a significant correlation was found between frequencies calculated from the
model and published values for CRI obtained by palpation. These comparisons
suggest that the CRI may arise in soft tissues and represents a complex
interaction of at least four different physiologic rhythms.

Next issue of the Dural Connection Internet Edition will include some very
interesting poster presentations gleaned from the Fortieth Annual AOA
Research Conference Abstracts, 1996: Part 2 which were published in The
Journal of the American Osteopathic Association , September 1996 issue.
