Research Shows Spinal Dysfunction Affects Reaction Times and Performance
research project published in the September 2005 issue of the peer reviewed
scientific journal, The Journal of Manipulative and Physiological
Therapeutics, JMPT, showed that "Spinal Dysfunction" (more commonly known as
subluxation in chiropractic) is related to slower and/or less accurate
reaction times and therefore to cognitive function.
The double-blind, randomized,
study was performed on thirty volunteers who had evidence of what the
researchers called "cervical spinal joint dysfunction". Researchers at the
New Zealand Chiropractic College examined the volunteers to determine areas
of spinal dysfunction. It was then noted how many areas of spinal
dysfunctions were found on each subject and this information was compared to
the results of the reaction times testing done later.
A range of computer-based
tasks were then performed by the volunteers in order to determine various
types of reaction time. The reaction times of the volunteers was then
compared to their number of areas of spinal dysfunctions to see if there was
The results showed that there
was a connection between the number of areas of spinal dysfunction and
certain types of reaction times. Researchers noted that the types of
reaction times affected by multiple areas of spinal dysfunction were
therefore related to impaired cortical processing and significantly less
accurate response selection. In fact, they found that the more areas of
spinal dysfunction, the more it affected reaction times.
The researchers concluded
that certain types of reactions times could be good indicators of the
effects of "cervical manipulations" (adjustments) in people with spinal
dysfunctions, (subluxations). The ramifications of this study could
not only affect general health, but could offer great benefits for athletes.
