Myths?
< You've been extremely
critical in the recent past of training TVA (even
though solid literature
was being cited), now you're saying it's
"scientific"? Have you
changed your strong opinions? >>
*** I don't know how you could
infer that from what I cited. I simply shared
the observations of
someone who worked professionally with Richardson,
Hodges etc, but
offered no comments on whether or not isolated TvA activation
is of any
value in enhancing trunk stability of non-pathological patients
or
diminishing LBP in some populations.
My view is that it is
oversimplistic to consider any single muscle as the key
to any dynamic
mobility and stability of the trunk over all of its range
of
movement. Moreover, far too much is sometimes made of changes in
the timing
of TvA activation in LBP patients because similar changes occur
in several
muscles prior to movement (see articles and books by
Berthoz, for example on
this issue). We need to appreciate that a
great deal of motor action
involves predictive, feedforward processes, so
that all the research being
done on real-time proprioception and feedback
processes needs to be balanced
with much more research on the predictive,
"virtual reality" aspects of
movement which take place in the central
nervous system before movement even
begins.
