A summary of the replies I received to this query follows:

"Apparently there is "cutting edge" neurophysiological research that
demonstrates an improvement in sport performance as a result of spinal

"Any references and/or opinions would be greatly appreciated."

As you will see in the following, there is essentially nothing that has
been said about this relationship in the literature. The reason that I
posed the question originally was related to a presentation being made by a
group of chiropractors to an elite athletic population. They made an
appeal for continued spinal manipulation treatment on the basis that it
would improve performance. References were requested and none followed, so
I thought perhaps someone might know of this.

I have certainly seen some interesting clinical/anecdotal outcome from
manipulation of the human spine, but I was disturbed by this apparently
pseudoscientific marketing technique. If anything becomes available in the
future, I would be happy to receive such references.

Many thanks!


Dear Greg
If you come up with any references I would be most interested. I fear that
in the past, attempts to show various effects of manipulation have had poor
study designs and conclusions not validated by the studies.


Dear Greg,
Like most of medicine, there is little substantive evidence but much
experience claimred with manipulation and optimization of performance. The
hard science inmanipulation is just now beginning to appear and is related to
quantifying its biomechanical characteristics and getting clues as to the real
nature of the lesions. An organized epidemiological study is needed to
establish that the observtions and impressions of the atheletes and their
doctors is the operant feature of their experience.

Names that are prevelant in the literature on manipulation biomechanics are
Herzog, Lee and Triano (each from separate centers). If you are interested in
helping put together an epidemiological study on this topic let me know. We
have a clinical epi person and would be interested in partnering with groups
who have access to athletes and relevant means of measuring performance.

Dear Greg,

I am afraid I have only one reference on the increase performance
following SMT. Could you please send me the usual posted summary?
