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feature some unpublished Senior Research Projects from,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

••• 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.
