1.1.1 Group Discussion
Questions
1.1.1.1.1 What was the funding source
for this research project?
1.1.1.1.2 Did the people in the study
as a whole have a significantly impaired lumbar range of motion pre-treatment?
Was it within the normal range?
1.1.1.1.3 Did the comprehensive
massage therapy group (Group # 1) have significantly improved scores at
follow-up compared with the soft-tissue manipulation group (Group # 2)?
1.1.1.1.4 Were subjects and or
therapists/PTs/Trainers paid and if so how much?
1.1.1.1.5 Can we get charts and other
ancillary material depicting/describing stretches/postural education massage
techniques used?
1.1.1.1.6 Would
the less expensive form of massage therapy (Is there a less expensive version
in Canada) performed by non-registered therapists be as effective as the $50
version performed by registered massage therapists?
1.1.1.1.7 Would
untrained unregistered massage therapists produce similar results?
1.1.1.1.8 How much did this research
cost?
1.1.1.1.9 Given
that the author agrees this would have been a better control treatment how much
more would sham massage have cost to do?
1.1.1.1.10 Is
blinding therapists, subjects, and assessors more expensive and time consuming
in a research project? If so how much?
1.1.1.1.11 Was
there a time constraint to the research?
1.1.1.1.12 Despite
the fact that the providers of both the sham laser and exercise treatment
groups believed that the exercise to be an effective remedy, at posttest 8% of
the subjects in the sham laser group indicated that they had no pain as
compared with 5% in the exercise and education group. Does this mean that
blinding therapists in this experiment would have no effect on the reported
treatment effects of subjects? Have other studies been done about the effect of
therapists expectations on the self-reporting behavior of subjects?
1.1.1.1.13 What
other research studies have followed this one and have added to our knowledge
of subacute (falling between acute and chronic in character especially when
closer to acute less marked in severity or duration than a corresponding acute
state) low-back pain?
1.1.1.1.14 Doesn’t
the fact that there was no improvement in actual function (range of motion test
(Schober)) invalidate the results of the Roland Disability Questionnaire (RDQ),
which relies on patient assessment? How well researched is the RDQ score?
1.1.1.1.15 How well are the self-rated
measures (RDQ, PRI & PPI, state anxiety) researched for reliability,
validity and internal consistency?
1.1.1.1.16 Isn’t
one person’s rating for intensity of pain (PPI) for example different from
another persons? Perhaps the same person may even rate the pain differently on
different days? Aren’t these self-rating numbers based on a nominal scale (Scales) which
although indicate greater and or less than values have indeterminate intervals
between numbers and therefore defy statistical analysis?
1.1.1.1.17 Wouldn’t
a better research design just have done away with the self-rating tests and
just used objective measures with blinded assessors?
1.1.1.1.18 Why
was Analgesic use permitted?
1.1.1.1.19 Are
Self-reported criteria (past history info) are unreliable?
1.1.1.1.20 Subjects
were told in the advertisements they might receive "one or more
modalities" This according to Preyde might dilute their expectations.
Expectations of what? That comprehensive massage was the therapeutic treatment.
1.1.1.1.21 According
to Preyde each group had approximately the same dropout rate (1 or 2 per group)
What does this have to do with Oppel & Sedergreen comments?
1.1.1.1.22 Is
it true as Preyde states that no study has employed a truly objective measure
of subacute back pain (e.g., laboratory investigations)
1.1.1.1.23 Preyde
states that history taking and physical examination (was this by a physician
other than the subjects physician) helped rule out both contraindications to
massage therapy as well as exclusion criteria. She seems to be implying a
greater physicians role than was apparent in the research. Was there a greater
physicians role?
1.1.1.1.24 Preyde
doesn’t think ancillary tests are appropriate. I assume she is referring to
ruling out cancer. Can't be sure cause this passage is vague. But she does cite
the following research.[1]
Is Preyde referring to cancer?
1.1.1.1.25 Should medication use have
been prohibited of subjects for this study?
1.1.1.1.26 The author makes two
references in her research article to the use of a registered massage
therapist, why was this important when this factor (training level of
therapist) was not being tested? (the specific techniques of soft tissue
mobilization; friction, trigger point therapy, and neuromuscular therapy were
the independent variables) First the author cites the fault of previous
research in not using registered therapists [2] Second the authors cites her
own use of registered massage therapists in research and her own status as a
registered massage therapist [3] Are there studies to
indicate that registered massage therapists result in improved treatment
results? The author has an affiliation with the College of Massage Therapists of Ontario which has
as its mission statement "All qualified massage therapists are registered
and proud to be associated with the College" In her summary conclusion the
author states "Patients with subacute low-back pain were shown to benefit
from massage therapy, as regulated by the College of Massage Therapists of
Ontario and delivered by experienced massage therapists." [4] Were the registered massage
therapists in this research study registered by the College of Massage
therapists? Similar emphasis of place of educational certification was not placed
on the other providers of treatment in this research study e.g. personal
trainer, weight-trainer supervisor & physiotherapists. We do not learn for
example that their training/registration/certification/schooling benefited the
outcome of the research. Is there bias in this research which may have been
transmitted to the subjects (subjects use self-rating of pain and function
which may be influenced by therapeutic bias) by the proud registered massage
therapy providers (the author included) who at least in the case of the author
were a member of the college of massage therapists?
1.1.1.1.27 How
can Group 1 be statistically superior to group 3 since there are no reported
statistical differences between group 1 and group 2?
1.1.1.1.28 Was
there a significant difference between the means of the Lumbar range of motion
(ROM) (Schober) of the 4 groups? The P-Values
listed in Table 3 (Outcome
Measures) of the research paper are .04 which being less
than a significance level of .05 indicates significant difference between
groups. Why did the author not report this? What is the meaning of this
difference?

Introduction/Instructions
1.1.2.1.2.1.1
The Roland Disability Questionnaire (RDQ) (AKA
Roland-Morris Questionnaire (RMQ)) uses a 24-point scale. The test asks the
patient to check off the functional limitations imposed by back pain that the
client feels TODAY. The greater the number of items checked by the patient the
greater the disability. Improvement can be calculated as a percentage of the
total number of disabling attributes before and after a series of treatments.
If, for example, at the beginning of treatment, a patient’s score was 12 and,
at the conclusion of treatment, her/his score was 2 (10 points of improvement),
we would calculate an 83% improvement. (10/12=83%).
1.1.2.1.2.1.2
Place the total score in the box on the bottom
left of the form and the percentage improvement in the box on the bottom right
of the form.
1.1.2.1.2.1.3
In terms of point increases/decreases a change of 2.5 points or greater considered
clinically significant.
1.1.2.1.2.1.4
Some
practitioners have inserted back pain and/or leg pain. This is because
sometimes clients don’t feel pain in their back but rather in the legs referred
from the nerve root, which emanates from the lower lumbar vertebrae. The
problem (nerve root irritation) is still a problem in the low back. This
practice may more accurately reflect a client’s disability but has not as yet
been validated as a disability test.

1.1.2.1.3.3.1
Introduction/Instructions
1.1.2.1.3.3.1.1
Developed in the 1980’s assesses the quality of
pain with both sensory (S-PRI) and affective
(A-PRI) measures. The intensity of pain is assessed using a visual
analog scale and a numbered (0-5) ordinal list (PPI).
1.1.2.1.3.3.1.2
Each sensory and affective pain quality is rated
on a 0-3 scale where each number is characterized by a descriptor (0=None,
1=Mild, 2=Moderate, 3=Severe).
1.1.2.1.3.3.1.3
Subjects are asked to limit their pain to the
pelvic region only while rating each of the pain qualities with a number
between 0-3. Once completed the tester computes and marks the score for the
S-PRI & A-PRI and adds the total of these scores into the T-PRI (Total Pain
Rating Index) Box.

Modified Schober test (lumbar range of motion) [5]
[6]
1.1.2.1.5.1
The modified Schober method: a technique for
assessing spinal motion. Although the technique is reliable (Moll & Wright,
1971), its primary usefulness may be in screening for the very limited mobility
that patients exhibit who have diseases like ankylosing spondylitis.
1.1.2.1.5.2
Use a pen to mark the midpoint between the
posterior superior iliac spines (PSIS). Then use your tape measure to identify
and mark two points: (1) one that is 10 cm superior to the PSIS, and (2) one
that is 5 cm inferior to the PSIS.
1.1.2.1.5.3
As the client flexes the spine as far as possible,
measure and record the distance between the superior and inferior marks.
1.1.2.1.5.4
Similarly, measure and record the distance between
the superior and inferior marks as your partner extends the spine as far as
possible.

2.1 Group Discussion
Questions
2.1.1.1 How can the
responsible therapist determine which techniques are scientifically valid?
2.1.1.2 Do massage
therapists have any obligation to practice and or learn scientifically valid
approaches with their clientele?
2.1.1.3 Aren’t the
techniques taught in schools validated scientifically?
2.1.1.4 Isn’t the
therapist’s heartfelt belief/experience in a therapeutic approach good enough?
2.1.1.5 Aren’t our
intuitions mostly right about what is effective therapeutically with our
clients?
2.1.1.6 Do
entrepreneurs/therapists who are selling the tapes/books/seminars have a
responsibility to give back to the profession by supporting research on their
methods?
2.1.1.7 Do massage therapy
organizations have an obligation to encourage consumer education to seek out
therapists who practice with an evidenced based approach?
2.1.1.8 Should National
Certification/Licensing exams include Research Literacy as testable
Professional Competency?
2.1.2.1 Is there cultural
resistance to the scientific study within the massage profession?
2.1.2.2 Does the current
massage culture value research literacy?
2.1.3.1
2.2 Group Activities
2.2.1 What is the best
way to locate research online with about as much time as you have between
back-to-back clients?
2.2.2 Case
Study-Pregnancy & Nausea
2.2.2.1 Your pregnant
client has just arrived with a doctor’s prescription for massage therapy to
help with nausea and vomiting. Your client is getting dressed and you have
about 5 minutes or less to research this case. You have no prior knowledge of
the subject. Your client asked for this referral from her doctor because she
didn't want all of the drugs in her system. The client says her doctor is
clueless about alternative medicine including massage. She has rather chronic
nausea and vomiting to the point where her back around the rib cage has been
aching. The doctor has requested that you E-Mail him a brief explanation and
result of the services you provided. There is no right or wrong answer to this
case study.
2.2.2.2 Which of these
resources or combination of resources helps you best? Remember to time yourself
for each one.
2.2.2.3 For the following
you will need to type in the words; pregnancy nausea massage
2.2.2.4 Please try these
and let the whole group know what you discovered and what additional resource
you may need.
3.1 Understanding
Research Concepts
3.1.1 Statistical
Concepts-Measurement-Scales
3.1.1.1 Pythagoras (569-475 BCE) is considered the
first mathematician to see relationships in the world of objects by measuring
them. Objective (think SO(objective)AP notes) measurement is still done today
with modern statistics which is at the heart of every research paper you will
read or used when ever you report clients objective progress. Technically only
two scales of measurement can be used to produce meaningful statistics namely;
interval and or ratio. There are work arounds which researchers have developed
to obtain meaningful statistics from ordinal (self reported scales). To
understand the, aforementioned scales a quick review of all the scales is
helpful. There are four kinds of scales;
3.1.1.2 Nominal
3.1.1.2.1 Numbers are names for things.
Example; football jerseys.
3.1.1.3 Ordinal
3.1.1.3.1 Numbers are names for things
and can be arranged in descending/ascending order. Example; Self-rating scales,
Finish places in a race, IQ.
3.1.1.4 Interval
3.1.1.4.1 Numbers are names for things,
can be arranged in ascending/descending and are of equal intervals. Example;
centigrade thermometer.
3.1.1.5 Ratio
3.1.1.5.1 Numbers are names for things,
can be arranged in ascending/descending order, are of equal intervals, have a
true zero point, and ratio statements can be made such as 20 minutes is twice
as long as 10 minutes. Example; Height, width, weight, and time.
3.1.1.6 Conclusion
3.1.1.6.1 Hard sciences such as
physics, chemistry, and medicine have used almost exclusively interval and
ratio scales to measure objects of scientific study. (Earths circumference,
chemical concentrations, and star brightness) Soft sciences such as psychology,
sociology have used ordinal scales because it is impossible for a scientist to
look in a person’s mind and measure depression with a ruler for example.
Physical therapy, chiropractic and massage therapy have also used ordinal
scales for example to measure pain since we can't feel a clients pain directly.
The problem is statistics cannot be performed with ordinal scales as
aforementioned and so a compromise has been achieved. Research has been
designed so that the influence of the researcher, subject and others does not
influence what are essentially subjective rating scales. Extensive research has
been conducted to correlate (more about this concept later) these subjective
measures with objective measures. For example, High IQ has been associated
greater levels of academic performance. Higher self-rated functioning has been
correlated with greater objective functioning. The aforementioned professions
have then treated these self-rated measures as if they were interval scales so
that research could be conducted and statistics derived.
3.1.1.6.2 Some hard scientists call
this practice into question and are skeptical of self-rated measures.
3.1.1.6.3 What do you think? If you are
not sure ask a question to get more information.
3.1.1.6.4 In Biophotonics and with a
Photomultiplier individual photons can be counted as they emanate from the
body. Since damaged tissue e.g. connective tissue, muscle tissue produce
greater photon emissions http://www.anatomyfacts.com/Research/photonc.htm it
should be theoretically possible to further develop even more precise ratio
measurements of a persons discomfort and the effects of soft tissue
therapy/manipulation. Because photon counts would use a ratio scale with a true
zero point these objective measurements can better be statistically correlated
with client self-reports. If photons truly guide the inter and intracellular
metabolic and biochemical processes we would be viewing living organic
processes better than current static imaging would allow (MRI, X-Ray). More
research and collaboration with biophysicists is needed to perfect effective
protocols.
