<h2>Context</h2>
|
|
<p>
|
|
A correlation has been established between the Traube-Hering-Mayer
|
|
oscillation in blood-flow velocity, measured by laser-Dopper-flowmetry,
|
|
and the cranial rhythmic impulse.
|
|
</p>
|
|
<h2>Objective</h2>
|
|
<p>
|
|
To determine the effect of cranial manipulation on the
|
|
Traube-Hering-Mayer oscillation.
|
|
</p>
|
|
<h2>Design</h2>
|
|
<p>
|
|
Of 23 participants, 13 received a sham treatment and 10 received cranial
|
|
manipulation.
|
|
</p>
|
|
<h2>Setting</h2>
|
|
<p>
|
|
Osteopathic Manipulative Medicine Department, Midwestern University,
|
|
Downers Grove, Illinois.
|
|
</p>
|
|
<h2>Participants</h2>
|
|
<p>Healthy adult subjects of both sexes participated (N=23).</p>
|
|
<h2>Intervention</h2>
|
|
<p>
|
|
A laser-Doppler flowmetry probe was place on the left earlobe of each
|
|
subject to obtain a 5-min baseline blood flow velocity record. Cranial
|
|
manipulation, consisting of equilibration of the global cranial motion
|
|
patter and the craniocervical junction, was then applied for 10 to 20
|
|
minutes; the sham treatment was manipulation only.
|
|
</p>
|
|
<h2>Main Outcome Measure</h2>
|
|
<p>
|
|
Immediately following the procedures, a 5-min postreatment laser-Doppler
|
|
recording was acquired. For each cranial treatment subject, the 4 major
|
|
components of the blood-flow velocity record, the thermal (Mayer)
|
|
signal, the baro (Traube-Hering) signal, the respiratory signal, and the
|
|
cardiac signal, were analyzed, and the pretreatment and posttreatment
|
|
data were compared.
|
|
</p>
|
|
<h2>Results</h2>
|
|
<p>
|
|
The 10 participants who received cranial treatment showed a thermal
|
|
signal power decrease from 47.79 dB to 38.490 dB (P < .001) and the
|
|
baro signal increased from 47.40 dB to 51.30 dB (P < .021), while the
|
|
respiratory and cardiac signals did not change significantly (P > .05
|
|
for both).
|
|
</p>
|
|
<h2>Conclusion</h2>
|
|
<p>
|
|
Cranial manipulation affects the blood-flow velocity oscillation in its
|
|
low-frequency Traube-Hering-Mayer components. Because these
|
|
low-frequency oscillations are mediated through parasympathetic and
|
|
sympathetic activity, it is concluded that cranial manipulation affects
|
|
the autonomic nervous system.
|
|
</p>
|
|
<h2>Introduction</h2>
|
|
<p>
|
|
Cranial manipulation is a form of broadly practiced alternative, manual
|
|
medicine. A fundamental component of cranial manipulation is the primary
|
|
respiratory mechanism (PRM).<sup>1</sup> It is described as an
|
|
oscillation that is palpable; the cranial rhythmic impulse (CRI)2 has an
|
|
agreed-upon frequency of 10-14 cycles per minute (cpm).<sup>2,3</sup>{" "}
|
|
The PRM/CRI is a subtle phenomenon that is readily palpable only by
|
|
experienced individuals, making its very existence subject to debate.{" "}
|
|
<sup>4,5</sup>
|
|
</p>
|
|
<p>
|
|
The Traube-Hering-Mayer (THM) wave is a complex oscillation in blood
|
|
pressure and blood-flow velocity. The Traube-Hering (TH) component of
|
|
this oscillation has a frequency of 6 to 10 cpm. Analysis of the TH was
|
|
first described in 1865, when Ludwig Traube reported the measurement of
|
|
a fluctuation in pulse pressure that occurred with a particular
|
|
frequency of respiration but persisted after respiration had been
|
|
arrested.<sup>6</sup> Fourier-transform analysis applied to blood
|
|
physiologic parameters shows that this fluctuation consists of 3
|
|
principal spectral peaks: the thermal or Mayer (M) wave (1.2-5.4 cmp),
|
|
the baro or TH wave (6.0-10.0 cpm), and the respiratory wave, which
|
|
shifts in frequency with changes in the respiratory rate.7 Multiple
|
|
authors have commeted on the similarity between the TH wave and the CRI.
|
|
<sup>8-11</sup>
|
|
</p>
|
|
<p>
|
|
By comparing cranial manipulation with laser-Doppler flowmetery, we have
|
|
demonstrated that the PRM/CRI is congruous with the TH component of the
|
|
THM oscillation in blood flow velocity.<sup>12</sup> A question,
|
|
therefore, logically arises: can cranial manipulation affect the THM
|
|
oscillation?
|
|
</p>
|
|
<h2>Method</h2>
|
|
<p>
|
|
Healthy adult subjects (both sexes, N=23, institutional review
|
|
board-approved informed consent obtained) were divided randomly into
|
|
cranial palpation (n=13) and cranial manipulation groups (n=10). A
|
|
laser-Doppler probe (BLF 21 Perfusion Monitor, Transonic Systems, Inc.
|
|
Ithaca, NY) was placed on the left earlobe of each subject. After the
|
|
subject was allowed to lie quietly on the examination table for 3
|
|
minutes of equilibration, a 5-minute baseline blood-flow velocity record
|
|
was obtained. Cranial manipulation or manipulation, with the physician
|
|
blinded to the flowmetry recording, was then performed for 10 to 20
|
|
minutes. Following palpation or treatment, a 5-minute postcontact
|
|
laser-Doppler recording was acquired. During this entire procedure, the
|
|
subject remained on the examination table, and the laser-Doppler probe
|
|
was not disturbed.
|
|
</p>
|
|
<p>
|
|
Cranial palpation (simply counting the CRI but without intervention) and
|
|
manipulation (therapeutic intervention) were performed while the
|
|
subjects were supine. The individual performing the procedure was seated
|
|
at the end of the examination table with hi or her forearms resting upon
|
|
it. The examiner's palms conformed to the curvature of the subject's
|
|
head, contacting the lateral aspect of the great wings of the sphenoid
|
|
bone and the temporal, occipital and parietal bones bilaterally. For
|
|
this study, similar contact pressure, firm, but light enough not to
|
|
ablate the sensation of the CRI, was employed for both palpation and
|
|
manipulation. Manipulation was directed at modulation of the rate,
|
|
rhythm, and amplitude of the CRI and perceived functional asymmetry
|
|
through equilibration of the craniocervical junction and global
|
|
anerioposterior cranial motion. Specific interventions were dictated by
|
|
the physical findings of the individual's cranial pattern.
|
|
</p>
|
|
<h2>Results</h2>
|
|
<p>
|
|
For each subject, 4 component parts of the blood flow velocity record
|
|
were analyzed: the thermal (M) signal, the baro (TH) signal and the
|
|
respiratory signal of the THM, and the cardiac signal. The mean
|
|
precontact and postcontact data for each group were compared using the
|
|
paired-samples 2 tailed t statistic (see Table). After palpation only,
|
|
the thermal signal power decreased 3 dB (42.93 to 39.58 Db, P <
|
|
.054), while the baro (39.83 to 40.10 dB, P < .805), respiratory
|
|
(27.54 to 27.20 dB, P < .715) and cardiac (37.92 to 37.14 dB, P <
|
|
.511) signals did not change.
|
|
</p>
|
|
<p>
|
|
After cranial manipulation, the thermal signal power decreased 9 dB
|
|
(47.40 to 51.30 dB, P < .021), while the respiratory (29.72 to 30.02
|
|
dB, P < .747) and cardiac (41.11 to 40.70 dB, P < .788) signals
|
|
did not change.
|
|
</p>
|
|
<p>
|
|
The 2 examples illustrated (see Figure), though visually exceptional,
|
|
illustrate the effects that can be obtained to varying degrees with any
|
|
subjecd, provided the treating physician possesses the requisite skill.
|
|
</p>
|
|
<h2>Comments</h2>
|
|
<p>
|
|
From the above data, we have drawn 3 conclusions. First, cranial
|
|
manipulation has an effect on low-frequency oscillations observed in
|
|
blood-flow velocity. It decreases the amplitude of the M wave and
|
|
increases the amplitude of the TH wave. Second, we conclude that cranial
|
|
manipulation affects the autonomic nervous system because it has been
|
|
demonstrated that the M an TH waves are mediated through parasympathetic
|
|
and sympathetic activity.7 Third, because palpation alone did not
|
|
greatly affect blood-flow velocity oscillations, we conclude that there
|
|
is a quantifiable difference between palpation and cranial treatment.
|
|
This conclusion suggests that palpation alone may be used as a sham
|
|
treatment in future research in the field of cranial manipulation.
