Femur Head Height Error on AP Pelvic X-rays
with Alterations of Source-to-Image Distance, Central Ray Position, and
Object-to-Film Distance
PETER R. SLANE and PETER W. BULL
Objective: To identify those factors that produce leg-length
insufficiency (LLI) projection errors on AP pelvic x-rays: altered
source-to-image distance (SID), altered central ray (CR) position, or
altered object-to-film distance (OFD). Method: Femur head height
discrepancy as apparent LLI was measured using a simulated femur head
model during altered source-to-image distance (SID) of 100 cm and 180
cm, and altered central ray (CR) projections at the level of the
xiphisternum (X), umbilicus (U), at the femur head height (FH), and at
the level of the femur heads with a tube tilt to the umbilicus level
(FHT) on AP pelvic x-rays. Altered OFD of +3 cm, 0 cm, and –3 cm
from neutral were created by manipulating the model. Results: The
greatest LLI error was at the CR position of X and U with altered OFD of
+3cm and –3 cm, which produced LLI errors of up to 9 and 8.5 mm
respectively. The SID of 100 cm resulted in greater LLI error across
conditions than the SID of 180 cm. The condition with the lowest LLI
error was the CR at FH with a SID of 180 cm. Conclusion: The use of
standard AP full-spine x-ray centred at X, and the standard AP
lumbo-pelvic x-ray centred at U, to determine LLI is invalid due to the
possibility of high LLI error at these CR positions created by pelvic
rotation. This work calls into question the validity of measuring LLI
with x-ray unless a CR at FH is used with a SID of 180 cm.

Sources of Stress for Chiropractors in
Private Practice
This research sought to identify the individual and work
characteristics that were related to the frequency of stressful events
for chiropractors in Victoria, and to identify the sources of stress.
Data were collected from 305 Victorian chiropractors using
questionnaires that were completed anonymously. Seven sources of work
stress were identified using principal component analysis of the Health
Professionals Stress Inventory (HPSI). The results demonstrated that
chiropractors in practice for over 20 years experienced fewer stressful
incidents at work than their younger colleagues. Practice experience was
negatively associated with stressful incidents from dealing with patient
care and conflict. Chiropractors seeing more than 150 patients per week
reported fewer stressful incidents than those with fewer than 150
patient visits per week. Increasing patient numbers per week was largely
beneficial, demonstrating a negative association with stressful
incidents dealing with personal job opportunities, patient care, and
professional performance. The only shortcoming of a busier practice was
more conflict issues. The results highlight the importance of experience
in clinical practice and that busier practices are largely associated
with fewer stressful work incidents.

Can the Ileocecal Valve Point Predict Low
Back Pain Using Manual Muscle Testing?
HENRY P. POLLARD, PETER BABLIS and ROD BONELLO
Background: According to some technique groups in chiropractic the
ileocecal valve may malfunction and be associated with a large array of
health problems that can lead to common chronic health issues prevalent
in our society. Many tests commonly used in chiropractic are presumed to
identify painful and/or dysfunctional anatomical structures, yet many
have undemonstrated reliability. Despite this lack of evidence, they
form the basis of many clinical decisions. One cornerstone procedure
that is frequently used by chiropractors involves the use of manual
muscle testing for diagnostic purposes not considered orthopaedic in
nature. A point of the body referred to as the ileocecal valve point is
said to indicate the presence of low back pain. This procedure is widely
used in Applied Kinesiology (AK) and Neuroemotional Technique (NET)
chiropractic practice. Objective: To determine if correlation of
tenderness of the “ileocecal valve point” can predict low
back pain in sufferers with and without low back pain. It was the
further aim to determine the sensitivity and specificity of the
procedure. Methods: One hundred (100) subjects with and without low back
pain were recruited. Subjects first completed information about their
pain status, then the practitioner performed the muscle testing
procedure in a separate room. The practitioner provided either a yes or
no response to a research assistant as to whether he had determined if
the subject had back pain based on the muscle test procedure. Results:
Of 67 subjects who reported low back pain, 58 (86.6%) reported a
positive test of both low back pain and ICV point test. Of 33 subjects,
32 (97.0%) with no back pain positively reported no response to ICV
point test. Nine (9) subjects (13.4%) reported false negative ICV tests
and low back pain, and 1 subject (3%) reported a false positive response
for ICV test and no low back pain. Conclusion: The majority of subjects
with low back pain reported positive ileocecal valve testing, and all
but one of the subjects without low back pain reported negative
ileocecal valve testing. The application of ileocecal valve testing as a
diagnostic measure of low back pain was found to have excellent measures
of sensitivity, specificity and diagnostic competency. This study
confirms that the use of this test within the limitations of this study
is reliably associated with the presence of low back pain. Further
testing is required to investigate all aspects of the diagnostic milieu
commonly used by proponents of this form of diagnostic testing.

The Private and Public Faces of Chiropractic
in Australia: Focus on Integration
STANLEY P. BOLTON
Integration of chiropractic into the healthcare system of any country
may be perceived as a measure of the effectiveness of its principles and
practice, the vision of its practitioners, and the vitality of its
organisations. Full integration of chiropractic into the totality of
Australia’s healthcare system involves both its private and public
healthcare sectors. This paper notes integration of chiropractic into
Australia’s private healthcare sector and records pioneer efforts
of Dr Lynton F. Giles to integrate chiropractic into Australia’s
public healthcare sector, and the project’s demise. It identifies
a new private hospital initiative in New South Wales, significant
broadening of the definition of medical practitioner in that State, and
discusses future prospects.
