Press Release: New Zealand Chiropractors' Association
International Researchers Say Chiropractic May Make
Your Mind Sharper
Ground-breaking research
indicates that chiropractic care may make your brain
function better, according to the New Zealand
Chiropractors’ Association (NZCA).
A collaborative study
on the effects of manipulation of the spine on brain
function between Denmark’s
Aalborg University, the
New
Zealand Centre for Chiropractic Research, the
Health & Rehabilitation Research Institute,
AUT University and
University of
Ontario Institute of Technology, published
earlier this year[1] in the journal
Neural Plasticity
suggests that, at least in part, the mechanisms by which
spinal manipulation improves performance are due to a change
in processing of information at the pre-frontal cortex.
Dr
Cassandra Fairest, chiropractor and spokesperson for the
NZCA explains: `The focus of chiropractic care is on the
health and integrity of the nervous system. The health and
function of the
spine affects the entire nervous system. We
already know that the spinal cord is an integral part of the
central nervous system and processes information just like
parts of the brain do[2] and the latest New Zealand research
into the effects of chiropractic care suggests that it may
have an important role to play in improving executive
function.’
Executive function is the mechanism by which
the brain integrates and coordinates the operations of
multiple neural systems to solve problems and achieve goals
based on the ever-changing environment around
us[3],[4].
The researchers point out that executive
function is considered to be a product of the coordinated
operation of various neural systems and is essential for
achieving any particular goal. The pre-frontal cortex is
believed to be the main brain structure responsible for
enabling this coordination and control. It requires planning
a sequence of subtasks to accomplish a goal, focusing
attention on relevant information as well as inhibiting
irrelevant distractors, being able to switch attention
between tasks, monitoring memory, initiation of activity,
and responding to stimuli[5].
Dr Fairest adds: `A change
in pre-frontal activity following chiropractic care may
therefore explain and/or link some of the varied
improvements in central nervous system function previously
observed in other research, such as improved joint position
sense error[6], reaction time[7], cortical
processing[8],
cortical sensorimotor integration[9], reflex
excitability[10], motor control[11], and lower limb muscle
strength[12].
`All this research, much of it from the New
Zealand College of Chiropractic Centre for Chiropractic
Research[13] and funded by th
e Australian Spinal Research
Foundation strongly suggests that chiropractic
care/adjustments can significantly improve brain¬-body
communication and coordination.’
According to
Dr
Fairest: `We know that chiropractic care assists brain
function in many ways, one of which is proprioceptive
function (perception) and this improves the accuracy of the
internal brain map so your brain accurately knows what is
occurring within your body and the surrounding environment
continuously. Environment relates to the processes inside
the body, as well as its immediate surroundings’.
The Way I See It.......it seems
this research suggests adjusting improves pre-frontal cortex activity, a part of the brain that is responsible for so much higher level function, then it is possible that a chiropractic adjustment could well impact on things like behavior, decision making, memory and attention, intelligence, processing of pain and the emotional response to it would seem that chiropractic really does have a lot to offer!
