HHi Will,
Yes - there is also further work occurring with testing inter-rater agreement
levels of practitioners using the Shen-
Hammer system. This is currently at an analysis stage and is being undertaken
by a dedicated and knowledgeable
practitioner of this system to meet requirements for a research degree, and so I
am not at liberty to discuss this further at
present. (But findings are interesting).
Emma and I also recently published a paper in the Journal of Complementary and
Alternative Medicine (2006; US
publication) which looked at inter-rater agreement levels and testing of the
left/right gender strength discrepancy
assumption discussed in the classical literature. (Males are stated as having a
stronger left side pulse relative to their
right side and females are said to have a stronger right hand pulse relative to
their left). While finding differences
between the strength of the pulse between the left and right sides, this wasn't
sex depended. An interesting outcome in
the sense that if there were sex related differences then this would mean the
validity of applying the Qi/Blood concept to
the Right/Left pulses would be invalidated. A real conundrum! Only a
preliminary start and as usual more work through
replication by other research groups is required. There have been several other
studies undertaken on the topic that pre-
date the work by Emma and I. However, these exist mainly in the form of thesis
writings and are difficult to access. The
earliest study I've come across is by Cole, a UK study conducted in 1977.
In response to Ingrid’s inquiry:
- intra and inter-rater reliability is important for any diagnostic system and
even more so with pulse diagnosis because of
its inherent subjectivity. Ingrid identified the key to overcoming this -
standardisation to the language and the method of
application. Once this occurs then any changes to the pulse are better
attributed to the patient's health status rather
than to differences in pulse method. I understand that Hammer's pulse
terminology/definitions were revised a few years
ago to address a few ambiguous terms for this reason.
As Are and Will noted you're still likely to find some personal interpretation
and variation in agreement between people
feeling the same pulse - and this is due to a range of reasons, experience not
the least of these. However, there should
be some level of agreement - this is the whole point of having a diagnostic
framework to interpret findings within. Yet
there are two stages to the pulse diagnosis process. The first stage is the
actual assessment of the pulse parameters.
Stage 2 is interpreting the assessment findings in a diagnostic framework. Hence
even with a standard method and
language for describing the changes in pulse parameters is being undertaken,
agreement levels between practitioners
could still break down in the diagnostic stage of using the pulse findings,
attempting to understand the pulse changes in
a health context. Ingrid described this as 'nuances for interpreting'.
Ingrid's proposed study model also raises other questions in studying this area.
Not least of which is how and when are
practitioners using pulse diagnosis: is it in combination with interview skills
or as a stand alone technique? If in
combination with interview then it is necessary to ensure that 'questioning'
doesn't influence the pulse assessment - or
should this be allowed to occur if practitioners are using pulse assessment in
this manner in clinic? But then is the
reliability of pulse diagnosis being assessed if this was allowed to occur? As a
stand alone technique the practitioner
could still be influenced by other non-pulse findings such as facial colour and
posture. These would also need to be
controlled in a study situation when investigating pulse diagnosis. Or should
they? It is interesting and depends upon
how pulse being used: Chinese/Oriental medicine is not a single system of
practice.
Hope this helps(?)
Take care,
Sean.
