Dr Siff,
Thank you for clearing up your comments on flaws in the studies on core
stability. I agree with you in that core stability cannot occur in
isolation, and is dependent on adjacent structures. Nevertheless, I seem to
get the impression that you believe the studies published so far on core
stability and the concepts of core stability are finished and fixed (from
what you have written so far), and will never change with the test of time,
and with people such as yourself asking excellent questions regarding the
matter. I think we are all beginning to see the bigger picture in core
stability, and enhancing this concept based on our observations and
available evidence.
Just as an example of this progression, take joint mobilisation. It began
with the concept that we were fixing subluxations inside the joint. This was
further broadened by the work of Dr Wyke in the study of articular
neurology. And now an article by Michelle Sterling and Gwen Jull on the
effects of C4/5 PA mobilisation influencing both the core stabilisation of
the cervical spine (deep neck flexors) and possibly the CNS through the dPAG
(dorsal Periaquaduct Gray) leading to sympathoexcitatory effects. I am sure
10 years down the track, something else will come up...
Regards,
Henry***
