Chiropractic adjustments improve brain function
The science, research, and patient outcomes from all over the world make it very clear; Chiropractic adjustments change the brain! Six specific studies, published in the last nine years, provide the foundation that helps explain how and why chiropractic adjustments influence so many aspects of human health, function, and behavior. The findings were significant. The following post-adjustment conclusions were made based on the research:
1) Journal of Neurophysiology(2007) called “Cervical Spine Adjustment Alters Brain in Asymptomatic Subjects”
In this study Drs. Heidi Haavik and Bernadette Murphy clearly show that a cervical spinal adjustment (ON PATIENTS WITH NO PAIN) influences the cortical brain and can create neuroplastic changes in the brain tissue. THIS IS HUGE! There are counselors and emotional modification programs that cannot create neuroplastic changes in the brain over months and months of therapy like one single chiropractic adjustment can. I believe the best part of this study is that the subjects receiving adjustments DID NOT have neck pain but had confirmed vertebral subluxation. (In other words....subluxation is not about pain!). My community needs to know that subluxation creates abnormal brain physiology without causing any known symptoms?
The adjustment they received had a direct influence on sensory input and resulted in attenuated brain cortical evoked responses. This means it changed their brain for the better! It was noted that “enhanced active inhibition” of the sympathetic nervous system tone occurred in ALL post-adjustment measurements! The other cool thing it proved was that it clearly wasn’t a placebo effect or just “laying on of hands”. One group was set up for an adjustment but the high velocity low amplitude thrust was not made and this group had NO cortical neuroplastic change.
The bottom line here is that the vertebral subluxation leads to a bombardment to the Central nervous System with afferent signals from joints and surrounding muscles. A chiropractic adjustment reduces excessive signals and improves altered input into the CNS, resulting in better adaptation to any internal or external input the brain perceives.
Know this.... How to improve brain adaptability is one of the most important areas of study today in all of healthcare. And NOBODY EFFECTS IT LIKE CHIROPRACTIC CAN DO WITH THE POWER OF A CHIROPRACTIC ADJUSTMENT!
2) Neural Plasticity, Volume 2016 called “Manipulation of dysfunctional spinal joints affects sensorimotor integration in the pre-frontal cortex: A brain source
“We do know that spinal function does affect brain function. There’s now solid evidence that adjusting the spine changes brain function. This is the fourth time that the effect of adjusting the spine has on the brain has been studied. This last time it was studied and confirmed by an independent medical researcher.” said Heidi Haavik, one of the researchers behind this recent study, published in the Journal of Neural Plasticity .
And, this study indicates that adjustments impact the function of the prefrontal cortex. Haavik is particularly excited about what this implies:
“The latest study suggests that the changes that we do see in the brain when we adjust the spine do occur in the prefrontal cortex. That part of the brain is like the conductor in the brain.”
Such a finding could explain many of the previous findings of chiropractic’s effects –
“An effect on the function of the prefrontal cortex could explain many previous research results, such as improvements in sensorimotor function relevant to falls-prevention; better joint-position sense in both the upper limb and the lower limb; improved muscle
strength in lower limb muscles; better pelvic floor control; and better ability to carry out mental rotation of objects.” observed Haavik.
If, as this research suggests, adjusting improves prefrontal cortex activity, a part of the brain that is responsible for just so much higher level function, then what does this mean in terms of chiropractic’s impact on things like behaviour, decision making, memory and attention, intelligence, processing of pain and emotional response to it, autonomic function, motor control, eye movements and spatial awareness?
Why This Study Matters. Again, this study not only shows that when we adjust subluxations we change brain function. It changes activity by 20% just by adjusting. And this effect may be on the conductor in the brain. This shows us that every time we’re adjusting someone, we’re having a big, positive effect on the brain.
And a brain that’s functioning differently and conducting its activities better is sure to have an effect on the body.
Beyond A Doubt, Adjusting the Subluxated Spine Changes Brain Function.
3) Journal of Medical Hypotheses (2015) called “Measurable changes in the neuro-endocrinal mechanism following spinal manipulation.”
There were measurable changes in the neuro-endocrine mechanisms following a thoracic spinal adjustment.
An increase in the sympathetic tone of the nervous system plays a significant role in visceral disease.
A spinal adjustment changes the tone of the sympathetic nervous system, thus influencing hormones through the neuro-endocrine pathways.
4) The Journal of Alternative Therapeutic Health Medicine called “Cerebral metabolic changes in men after chiropractic spinal manipulation.”
A $3 million P.E.T. scan was used to measure outcomes following a Chiropractic adjustment. (A P.E.T. scan is a powerful neuro-imaging technique used to investigate neuronal activity in the human brain)
Brain and nervous system changes were measured in subjects after receiving a cervical adjustment. The findings concluded an increase in glucose metabolism in all areas of the brain except the cerebellar vermis, significantly lowered results in the stress response scale and visual analog scale, reduced muscle tone, and a significant decrease in salivary amylase.
All of these measurements are major indicators in a reduction of stress hormones by inhibiting the tone of the central nervous system.
5) The Journal of the Neural Plasticity called “Manipulation of dysfunctional spinal joints affects sensorimotor integration in the prefrontal cortex: A brain source localization study.”
Ø Entire spine and both sacroiliac joints were assessed for segmental dysfunction (vertebral subluxation) and treated where they were deemed necessary by a registered chiropractor with 15 years of clinical experience
Ø High velocity, low amplitude thrusts were delivered to the spine or pelvic joints always less than 200 milliseconds in duration.
Ø A change in sensory-motor integration occurred after the spinal adjustment predominately in the prefrontal cortex.
Ø The study confirms that a single session of spinal adjustment of dysfunctional segments in subclinical pain patients alters somatosensory processing of the cortical level, predominantly with the prefrontal cortex.
6) The Journal of Clinical Neurophysiology called “Cervical spine manipulation alters sensorimotor integration: a somatosensory evoked potential study.”
A vertebral subluxation alters balance of afferent input to the central nervous system.
Imbalanced afferent input, due to subluxation, leads to “maladaptive neural plastic changes in the CNS.”
A subluxation negatively affects the brain’s ability to receive feedback from the body in order to create, sustain, and maintain optimal function throughout the nervous system.
The group within the study that received Chiropractic adjustments was described as having “enhanced active inhibition” of the nervous system.
This is an indication that a Chiropractic adjustment inhibits the tone of the nervous system in a way that cannot be replicated or changed by any other physical, emotional, or chemical strategy.
The research continues to build. Chiropractic adjustments achieve amazing results by improving brain function, and thus benefit almost every aspect of human performance. Unfortunately, most people still believe that chiropractic is only for back or neck pain problems. The research evidence disagrees. Because of this, all humans deserve the right to have access to chiropractic care if they so choose.
And as a result, Chiropractors must strive to educate on the wide scope of benefits uniquely achieved by chiropractic patients as the balance and integrity of their nervous system improves.
The science is clear that the spine is NOT just a hard protective covering around soft delicate nerve structures with moveable segments and discs in between that allow us to move.
The spine is a NEURO-SPINAL ORGAN that constantly sends critical input into the brain every milli-second that we are alive. This occurs so that the brain and nervous system can properly assess and adapt to its environment for ultimate survival of the organism.
CHIROPRACTOR’S AFFECT THAT WITH EVERY ADJUSTMENT!
This means any alteration or abnormalities to the neuro-spinal organ(Subluxation) will wreak havoc to the brain, its ability to comprehend and respond to its internal and external environment, and thus.....the health expression of the individual. THAT’S A FACT!
Understanding this helps us to realize the vertebral subluxation is one of the worst conditions a human can have!
