Dear Colleague:
The SOT Quarterly Research Update is
a service offered by SOTO-USA to keep doctors who are familiar with
sacro occipital technique (SOT) aware of the latest research related
events, papers, and concepts affecting our practices. Please contact me
directly at drcblum@aol.com if you are aware of others who might be
interested in receiving this quarterly newsletter.
Please don't miss SOTO-USA's 7th
Annual CLINICAL SYMPOSIUM, October 26-29th, 2006, in St. Louis,
Missouri at the Hyatt Regency - Union Station.
During the next few SOT Quarterly
Research Updates we will feature some unpublished Senior Research
Projects from, Logan College of Chiropractic, Proceedings of the Logan
College Student Research Symposium. There is hope that these authors
will consider working with SOTO-USA's research department to assist
them in submitting these interesting articles to both research
conferences and chiropractic peer review journals.

Psoas contraction and the effect on expiratory lung
volume
Haner B, Judge D, Starbuck E, Young D, Unger J,
Functional lung capacity is an important aspect of health.
This study sought to investigate the relationship between psoas muscle
contraction and functional lung volume. The psoas muscle attaches to
the diaphragm through the medial arcuate ligament. If the psoas muscle
is in a contracted state and fails to relax it is hypothesized that the
diaphragm will not be able to relax completely, thus diminishing
expiratory lung volume. Inability to expel air is a major aspect of
significant breathing difficulties, such, as asthma and COPD. This
study measured the functional expiratory volume (FEY), functional
expiratory volume in one second (FEV1), and maximum flow rate of 44
subjects. These subjects were divided evenly between control and
experimental groups. Pre-test flow rates for both groups were recorded
using a RC-100 flow meter and data recorded using Acugraph software.
Both groups had their psoas muscle tested and in the treatment group.
the. Sacro-Occipital Technique (SOT) release was performed. Post-test
flow rates were then recorded for all subjects. Results showed a
significant improvement in the post-
treatment FEV of the experimental group with a p-value of 0.027
measured using a 2X2 factorial ANOVA and a p-value of 0.0005 using a
two-tailed, paired t-test. FEV 1 and max flow rate both improved in the
post-treatment groups, but the results were not statistically
significant. These results indicate that psoas contracture does affect
total expiratory volume, but may not affect the speed or strength of
expiration. This study was the first to measure the effects of psoas
release on lung volume and confirms the need for further investigation.

Sacro-Occipital Technique and chiropractic
manipulative reflex technique effects on heart rate variability
Oliver J, Evans R, Thompson D,
There are seven aspects of SOT including Occipital Fibers/
Chiropractic Manipulative Reflex Technique (CMRT). The nervous system
branches and is measured at two frequencies: the sympathetic division
is measured at a low frequency whereas the parasympathetic at high
frequency. Heart rate variability is one method to detect the effects
of the nervous system which was monitored by BioCom Version 2.0.
Various students attending Logan College of Chiropractic were divided
in two groups to see the results SOT/CMRT has on the nervous system.
The treatment group, who received SOT/CMRT adjustments, consisted of 10
subjects. The comparison group contained 17 students, who received
adjustments outside this study. One factor influencing our study was
National Board Examinations during the later part of this study.
Results include the treatment group with a significant difference in
high frequency range at p=.026, whereas the comparison group displayed
an insignificant difference at p=.387. Based on results, SOT in
combination with CMRT may affect the nervous system by statistically
increasing the parasympathetic tone as evidenced by heart rate
variability.

Proprioceptive Insoles - The Next Generation in Foot
Insoles
Professor Dr Brian A Rothbart, Researcher, Podiatric
Biomechanical Engineer
Dr. Rothbart has revolutionized the integration of the
assending podiatric influences on posture and particularly
temporal mandibular disorders (TMD). He has published
extensively and has an excellent website documenting his
research [http://www.rothbartsfoot.info]. What are
proprioceptive insoles and how do they function? This year's
clinical symposium will feature a presentation on Dr.
Rothbart's work. Here is what Dr. Rothbart has to say on that
topic:
"Proprioceptive insoles apply a tactile stimulation to the
bottom of the foot. The location of this stimulation depends
on the foot type you are treating. The foot stimulation is
transmitted to the cerebellum, the balance center of the
brain. Acting on this signal, the cerebellum initiates a global
postural correction: the pelvis levels, the shoulders retract,
the head moves posteriorly over the cervical spine. This
shift in posture directs the weight bearing joints to function at
or nearer their anatomical neutral position, which in turn,
allows the body to readjust itself towards a state of
homeostasis.
"Proprioceptive insoles do not support the foot, an
important
distinction between orthoses incorporating arch supports and
proprioceptive insoles. Supporting the foot atrophies the
intrinsic plantar muscles ('use it or lose it'), the plantar
arches weaken, and the postural distortions exacerbate.
Proprioceptive insoles do not support the foot. They act
directly on the cerebellum, changing the postural hemostat.
Over time, a process of engramming occurs, patients are
able to use their proprioceptive insoles less and less and still
maintain their level of homeostasis (wellness)."

Cardiovascular Events in Patients
Homocysteine Levels, C-Reactive Protein, NSAIDS and
History of Myocardial Infarction & Cervical Spine Adjusting
Supplementation with folic acid and vitamins B-12 and B-6 has
been found to not reduce the risk of major cardiovascular events in
patients with cardiovascular disease (CVD), and may even be
deleterious. Dr. Joseph Loscalzo, from Harvard Medical School in
Boston, suggests that "the use of folic acid and vitamin B-12 in the
setting of mild hyperhomocysteinemia may alter the methylation
potential in vascular cells, resulting in a change in the cell
phenotype that promotes the development of plaque."

reasons. N Engl J Med. 2006 Apr 13;354(15):1629-32. Epub 2006 Mar 12.

In a related eariler article researchers found that,
"Increased homocysteine levels are a risk factor for atherosclerosis
and its sequelae. A common genetic mutation in
methylenetetrahydrofolate reductase (MTHFR), an enzyme required for
efficient homocysteine metabolism, creates a thermolabile enzyme with
reduced activity. Because MTHFR homozygotes have increased homocysteine
with low folate levels, this mutation may contribute to early-onset or
familial vascular disease. The genotype dependence of the folate-
homocysteine correlation further suggests that homozygotes for this
mutation may have both an exaggerated hyperhomocysteinemic response to
folic acid depletion and a better response to folic acid therapy"

ICAK-USA 2006 Conference - Chicago June 8-11, 2006
Food for Thought - Forward Head Posture (FHP)
At this past ICAK-USA Conference Charles L. Blum, DC,
representing SOTO-USA had the opportunity to share common postural
distortions familiar to chiropractors, dentists, and podiatrists. While
the end result of FHP is the same, each method of healthcare offers
valuable insights into this postural phenomena pervading humanity. At
this year's SOTO-USA Clinical Symposium in St. Louis October 26-29th,
this topic will be discussed in detail by Stephen Olmos, DDS, Richard
Gerardo, DC, Charles Blum, DC and others.
At the ICAK-USA conference, Jose Palomar Lever, MD noted in
his article, “Neurogait” that while the talus and hyoid both contribute
significant proprioceptive information to the brain, the talus has only
ligamentous attachments while the hyoid has only muscular.
Also at the conference Thomas Myers, LMT (author of the book
Anatomy Trains) noted in his lecture that when there is fascial
restriction along either the anterior or the posterior fascial lines,
either or both will ultimately cause a forward head posture and
increased suboccipital muscle tension.
