Reliability and Validity of
Manual Muscle Testing
In research arenas attempts are constantly being made to
understand the evidence and both add and critique studies in an effort
to unravel the various "truths." Reading related commentaries and
replies to the editor are wonderful ways to gain deeper understanding
and a greater grasp on the information. In the following three articles
this repartee helps shed light on muscle testing and its clinical use
in the chiropractic field.
"The manual muscle test (MMT) employed by chiropractors,
physical therapists, and neurologists was shown to be a clinically
useful tool, but its ultimate scientific validation and application
requires testing that employs sophisticated research models in the
areas of neurophysiology, biomechanics, randomized controlled studies,
and statistical analysis."
Cuthbert
SC, Goodheart GJ. On the reliability and validity of manual muscle
testing: a literature review. Chiropr Osteopat 2007, 15:4.
"The purpose of this commentary is to provide a critical
appraisal of the review, suggest conclusions consistent with the
literature both reviewed and omitted, and extricate conclusions that
can be made about AK in particular from those that can be made about
MMT. When AK is disentangled from standard orthopedic muscle testing,
the few studies evaluating unique AK procedures either refute or cannot
support the validity of AK procedures as diagnostic tests. The evidence
to date does not support the use of MMT for the diagnosis of organic
disease or pre/subclinical conditions."
Haas
M, Cooperstein R, Peterson D. Commentary: Disentangling manual muscle
testing and Applied Kinesiology: critique and reinterpretation of a
literature review. Chiropr Osteopat 2007, 15:11 (23 August 2007).
"We agree with" Haas, Cooperstein, and Peterson, "that it is
reasonable to make a distinction between standardized MMT and
non-standardized MMT. It is the second type of MMT that can tarnish the
reputation of clinicians using it as part of their diagnostic regimen.
In our opinion Haas et al have used non-AK research studies to condemn
MMT as a pre- and post-assessment tool for evaluating the efficacy of
chiropractic treatment." Cuthbert notes that,"... if MMT is reliable
and valid for NMS diagnosis then logically this reliability and
validity remains when a chiropractor uses MMT."

Effects of anterior cruciate
ligament (ACL) injury on muscle activity of head, neck and trunk
muscles: a cross-sectional evaluation
Tecco S, Salini V, Teté S, Festa F. Cranio.
2007 Jul;25(3):177-85.
"This study evaluated what may be the effects from pathology
of the knee, due to an anterior cruciate ligament (ACL) injury, to the
muscular activity of neck, head, and trunk muscles. Twenty-five (25)
subjects (mean age 28+/-9 years) with ACL injury of the left knee were
compared with a control no-pathology group.
"At rest, the areas of anterior temporalis and masseter in
the control group (normal ACL) showed a significantly lower sEMG
activity compared with subjects in the study group (injured ACL), both
in the right and the left sides (p<0.05). The same was found for the
sEMG activity of the areas of SCM and lower trapezius.
"In general, ACL injury appears to provide a change in the
sEMG activity of head, neck and trunk muscles." This study supports the
plausibility of ascending TMD influences coming from asymmetrical
myofascial and skeletal function.

Cranial Manipulation Can Alter
Sleep Latency and Sympathetic Nerve Activity in Humans: A Pilot Study
Cutler MJ, Holland BS, Stupski BA,.Gamber RG, Smith
ML. J Altern Complement Med. 2005 Feb;11(1):103-8.
Objective: To determine if cranial manipulation is
associated with altered sleep latency. Furthermore, we investigated the
effects of cranial manipulation on muscle sympathetic nerve activity
(MSNA) as a potential mechanism for altered sleep latency.
Subjects: Twenty (20) healthy volunteers (12 male, 8 female;
age range, 22-35 years) participated in this investigation.
Interventions: Subjects were exposed to 3 randomly ordered
treatments: compression of the fourth ventricle (CV4), CV4 sham (simple
touch), and control (no treatment).
Outcome measures: Sleep latency was assessed during each of the
treatments in 11 subjects, using the standard Multiple Sleep Latency
Test protocol. Conversely, directly recorded efferent MSNA was measured
during each of the treatments in the remaining 9 subjects, using
standard microneurographic technique.
Results: Sleep latency during the CV4 trial was decreased
when compared to both the CV4 sham or control trials (p < 0.05).
MSNA during the CV4-induced temporary halt of the cranial rhythmic
impulse (stillpoint) was decreased when compared to prestillpoint MSNA
(p < 0.01).
Conclusions: The current study is the first to demonstrate
that cranial manipulation, specifically the CV4 technique, can alter
sleep latency and directly measured MSNA in healthy humans. These
findings provide important insight into the possible physiologic
effects of cranial manipulation. However, the mechanisms behind these
changes remain unclear.

Sacro Occipital Technique
Organization - USA is a non-profit, professional organization formed to
promote the awareness, understanding and utilization of the Sacro
Occipital Technique method of chiropractic as founded and developed by
Dr. Major Bertrand DeJarnette.
The SOTO-USA family all looks forward
to seeing you in Nashville for October 25-28th, 2007 Clinical
Symposium. It will be a great opportunity learn the essence of SOT or
advance your SOT training with integrative classes in SOT, CMRT, and
Cranial. For those interested in working with the dental profession
treating TMD then this symposium will be leading the way.
