In 1976, PhD Neurophysiologist Irvin Korr published a series of papers with many references pointing to the fact that an alteration in a segment or area of the spine absolutely negatively affected nervous system function.
The bottom line in the work of Korr was how he showed that a vertebral subluxation creates a stress that causes an increased tone in the sympathetic nervous system. We now know that an increased sympathetic tone in the nervous system sets off a cascade of autonomic processes as if the body was being attacked. This increased tone leads to what we know to be the “fight or flight” behavior physiology.
Here is the thing...it is a good response that helps you in the acute situation, but will kill you chronically. What I mean by that is in the short term situation it is good; however, if it stays there long term it will destroy the body.
This increase in sympathetic tone increases stress hormones known as catecholamines (adrenaline and noradrenaline) and decreases relaxing hormones such as serotonin and relaxin. From decreased immunity and digestion to shutting down fertility, focus, attention, and energy.....this state of physiology is not what any healthy human should experience for any sustained period of time.

A study performed in 2011 revealed the impact of one single chiropractic adjustment can have on the tone of the nervous system.
Published in “Alternative Therapies Health Medicine”(Ogura 2011)(2), this study was done by 8 PhD’s and 1 Chiropractor. They used a PET scan as a powerful neuro-imaging technique to measure neuronal activity in the brain. They were able to take a radioactive analogue of glucose as a marker to measure brain glucose consumption as it would indicate brain metabolic activity post-adjustment. Their findings were ASTONISHING!! The study clearly demonstrated that the sympathetic tone of the nervous system was inhibited, salivary amylase was decreased (indicating a decrease in fight/ flight physiology), regional brain metabolic changes occurred, and muscle tone & pain intensity decreased following ONE single chiropractic adjustment.

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.
A chiropractic adjustment removes interference to the nerve system and improves brain function. It does this by improving spinal integrity and through improving segmental motion in subluxated areas.
On March 2, 2007 a landmark chiropractic study was published in the Journal of Hypertension(7). This was a well done study showing that precise chiropractic spinal adjustments were able to produce a reduction in both systolic (17mmHg) and diastolic (10mmHg) blood pressure that was sustainable over a 8 week period with “no adverse effects”.

This was a study published in the reputable Medical Journal of SPINE in 2005 and was done by a team of all Medical Doctors headed up by Dr. Steven Glassman. They measured posture in 752 subjects from the sagittal plane using full-spine x-rays. They took measurements from the C7 and took plumb-line measures as it relates to the sacrum.
Even minor forward head posture was shown to be detrimental. From breathing and heart rate, to pain and disability, all health markers that were measured worsened as the posture deviations increased.
All Chiropractic adjustments help to restore posture by improving motion and spinal integrity which improves afferent input into the spinal cord and brain, thus, allowing the body to comprehend and balance itself better in relation to gravity. chiropracticadvocate.com STUDY #4. “The Destructive Impact of Abnormal Posture” 20 Vertebral Subluxation plays a major role in bad posture and this study reveals the detrimental effects of deviated posture in a human.
“Hyperkyphotic posture predicts mortality in older communitydwelling men and women” J Am Geriatr Soc. 2004 Oct;52(10):1662-7.
This study observed health statistics of people over a period of time whose Primary Care Providers (PCP) were conventional Medical Doctors compared to those who had their PCP as Doctors of Chiropractic.
Those who saw Chiropractor first:
*60% less hospital admissions
*62% less surgeries
*59% less days in hospital
*85% less pharmaceutical costs
