This article (http://www.chirobase.org/02Research/crelin.html) was just posted on Chirotalk although I think it was sitting around on chirobase for a long time, as it was written back in 1973. You would think the chiro schools would have stopped teaching this by now, but I guess they make too much income off misleading students to stop with the meme proaganda.. oops, I mean propagation..
It is a refutation of the conceptual hallucination chiro is based on, i.e. the 'subluxation' of vertebrtae and pinching of nerves at that level. Check out the picture of a spine under full flexion load, and the point made that foramina are not closed at all.
This experimental study demonstrates conclusively that the subluxation of a vertebra as defined by chiropractic-the exertion of pressure on a spinal nerve which by interfering with the planned expression of Innate Intelligence produces pathology-does not occur. This is what should be expected when one recognizes that the vertebral column has been evolving for over 400 million years to support the body and protect the central nervous system. By a process of natural selection the vertebral column of mammals has evolved into one in which the articulations allow an overall range of motion so that individuals may function well for survival within their environment. At the same time the selective process has favored vertebral columns that have spacious intervertebral foramina in combination with the barest minimum of displacement between adjacent vertebrae-two factors that preclude impingement upon the spinal nerves as they pass through the foramina.
So, why oh why does this ridiculous idea persist? Why oh why does the whole branch of manual therapy known as vertebral manipulation still persist? Argh.
With the PT fav known as "mobilization", why do people 'hang around at the spine' (as Butler has called it...) trying to affect peripheral things through pushing away on what they think are spinal joints, buried under inches of soft tissue and protected by all sorts of cutaneous fast signalling nerves? Why do they suppose they are actually able to affect anything jointy under all that? Why do they not consider the neural inflow/outflow effects that must be going on long before the joints could possibly register anything? Argh again.
