Low Back Pain is well known to at least 80% of
The cause can be ascertained in many cases with the
help of modern diagnostic techniques such as MRI.
In other cases, these modern diagnostic techniques
only serve to exclude all known and understood causes leaving
"Non-Specific Low Back Pain"
(or "Discogenic Back
Pain" as there is some evidence that such pain originates in the disc.)
In this Website, I suggest that the origin for Non-Specific Low Back
Pain lies in an unexpected,
and as yet unrecognised, limitation in the flexion of the lowest two
disks, L4/5 and L5/S
These two discs, and only
these two, have evolved
in the human spine to
have their normal range of
flexion and extension
only on the extension side
of what might be
called the central position (parallel
sided). In other
words, the wedge shape of the disc,
as seen in lateral
x-ray, should always be maintained.
The thickness of the
disc anteriorly should always
be greater than the
posterior thickness. (This, of course,
applies to the natural
and pain free spine.)
