Nervous system important chiropractic study

You be the judge.


What if there was a simple way to eliminate 80% of the healthcare burden of the entire population.  How about 3 different ways?  This study may just shed light on how it could be possible.


What question did the study look to answer?


Researchers were testing the hypothesis that when stress alters the response of the nervous system this condition causes health decline, symptoms and reduced quality of life.  And that restoration of normal nervous system function allows for restoration of health, reduction of symptoms and improved quality of life.


What were they testing to check the nervous system?


Parasympathetic excess (PE). This is a dysfunctional state of the nervous system where the parasympathetic nerves are over active, but only when performing a stressful activity.


Stressful activities such as forceful breath holding and quickly standing up were done while assessing heart rate variability (HRV) to test for PE.


How did they correct the PE nervous system dysfunction?


3 methods were tested:

1.                        Drugs to block the parasympathetic nerves

2.                        Walking 40 minutes 5-6 times per week

3.                        Chiropractic

Results were rechecked after 3-4 months.


Who was tested?


12,000 hospital patients aged 6-100 years were checked for PARASYMPATHETIC EXCESS (PE).

60% of people had PE (the specific nervous system dysfunction in question)

It was common in all ages.


What were the results?


All groups showed spectacular improvements in not only their PE, but also dramatic reductions were noticed in:

-       Symptoms

-       Quality of life

-       Improved outcomes in patients with specific diseases


 Results highlights


-       All groups did well

-       The chiropractic and walking groups got the best results

-       83.7% of patients showed improvement in their nervous system response to stress

-       This included 63.5% of people whose PE was gone (they no longer had parasympathetic excess) and 20.3% who improved and were considered works in progress

-       Of the 83.7% whose PE improved, their reported symptoms were relieved by 81.6% - that is REMARKABLE!

-       Of the subset of patients who had both PE and drug resistant diseases (hypertension/diabetes/hypothyroid) 85.4% showed “good improvement” – again REMARKABLE!

-       Of the subset of patients who had PE and poor sleep – 54.8% had normalization of their sleep and their other associated symptoms (fatigue/depression/digestive issues)

-       Of the subset of patients with cardiovascular disease and PE – 48.6% reduction in the severity of self reported symptoms was experienced, including (sleep problems/dizziness/depression/GI upset)


What symptoms were reported to improve after PE was improved?


-       Gastrointestinal upset

-       Sleep difficulties

-       Depression

-       Dizziness

-       Fatigue

-       Pain syndromes

-       Difficult to manage weight loss

-       Unexplained palpitations/arrythmias

-       Seizures

-       Anxiety

-       Attention deficit disorders

-       Exercise intolerance

-       Sexual dysfunction

-       Headache

-       Migraine


What general health measurements improved in patients of this study?


Many general health measures improved including:


-       Blood sugar control HbA1C levels

-       Thyroid hormone level control

-       Blood pressure

-       Female hormone level control




How can these results be explained?  Understanding the nervous system is the master system controlling your body and health.



To fully appreciate the importance of this study you need to know about the autonomic nervous system. (ANS)

-       The ANS controls the functions of the organs, glands and blood vessels.  The important stuff.  It has 2 parts:


1.                        The parasympathetic nervous system (PNS) (rest and digest, or brake which aids with repair and digestion)

2.                        The sympathetic (SNS) (fight and flight, the accelerator, releasing stress hormones, speeding the heart rate, raising blood pressure to cope with danger).


Also important to understand is that one branch is like a brake (PNS), the other is like the accelerator (SNS) and for a long time it was presumed when one was on the other was off.  Heart rate variability testing has demonstrated that they can both be on together.  Like a car doing a burnout.


What causes parasympathetic excess?


-       What causes PE? Basically stress, but chronic.  What should happen under stress is the SNS is active while the PNS remains relatively inactive.  But with chronic stress the ratio of SNS activity to PNS activity has to remain in a certain ratio or the body would become dangerously imbalanced so the wisdom of the body ramps up the PNS activity to maintain the balance btw the 2 divisions of the NS.  If this occurs often the body habitually increases the PNS whenever the SNS is provoked such as getting up from bed or a chair which means the SNS has to be over active to overcome the effect of the PNS brake adaptation.  Like driving with the handbrake on.  Over time this is inefficient and sets the stage for many symptoms and eventually adaptive reserves run dry allowing for health problems to develop.


How do the 3 methods to address PE actually work?


1.            Drugs to block the parasympathetic nerves.


Drugs which block these nerves prevented the excess parasympathetic nerve activity under stress.  However they also prevented normal activity of these nerves when blocking was not needed, such as during rest and sleep when we actually want these nerves firing.  This caused some side effects in the drug group.


2.            Exercise


Most remarkable re: this study is that chiro and exercise both normalised the stress response within 6 months.  Exercise was low impact 40 min 5-6x per week for 6 weeks then 3-4x week for remainder of 6 months.  Exercise which is relaxing such as walking causes an adaptive response of the body to expect more relaxing exercise in the future which improves the tone and function of the nerves, so when you experience future stress the nervous system can respond in a healthy manner.


3.            Chiropractic


It was impressive to see chiropractic also normalise the nervous system response to stress in this study.  Chiropractic specific adjustments aim to correct the alignment of the spine thus removing interference to the nervous system.  The premise of chiropractic is that the body can self heal and regulate with a healthy nervous system free from interference.  Improving the spine alignment and function with chiropractic adjustments removes one potential cause of that interference.  This study supports that premise.




Using this study to improve your health



Consider the implications if PE was routinely checked for and addressed with chiropractic + exercise such as a daily 40 minute walk for a healthy nervous system.  This study suggests >80% of healthcare burden could evaporate.


I was excited when I first heard about this research and hopefully you appreciate why I consider this one of the most important studies most people have never heard of.
