A study performed in 2011 by 8 PhD’s and one chiropractor studied the impact of one adjustment in the TONE of the nerve system. The tone of the nerve system refers to the STABILITY of system under stress.
They used a PET scanner – a powerful neuro imaging technique to measure neuronal activity in the brain. Literally they measured the METABOLIC ACTIVITY OF THE BRAIN and the changes post-adjustment. (Cerebral metabolic changes in men after chiropractic adjustment, Alt Ther Health med 2011 Nov-Dec; 17(6):12-17)
The results were astonishing!
First of all, in order for someone to receive a chiropractic adjustment, they must first have a subluxation. A subluxation is a misalignment in the spine that interferes with the normal transmission of nerve impulses throughout the body. Of course, since the nerve system controls and regulates all function, healing and development in the body, as subluxation is very detrimental to the health of the individual.
This PET scan study evaluated some of the systemic changes that happened once the subluxation was corrected with an adjustment.
What they found was that the SYMPATHETIC (STRESS) tone of the nerve system was inhibited, salivary amylase was decreased, regional improvement in brain metabolism, and muscle tone and pain intensity decreased.
Here’s why this is important:
It proves, again, that a subluxation creates abnormal proprioception into the brain (specifically the hypothalamus) leading to increased sympathetic tone.
That means that when you are subluxated, it is as if your body and brain is MASSIVELY and CHRONICALLY in a state of STRESS. Not OK!
Why is that so bad?
Well, increased sympathetic (STRESS) tone always increases stress hormones – which have been linked, through research, to all kinds of disease such as cancer, glaucoma, bi-polar disorder, type I and II diabetes, rheumatoid arthritis, autoimmune disease, osteoarthritis, excessive body weight, hypertension, asthma, and immune system disorders. (Autonomic and Autocoid Pharmacology, 2009)
Are you starting to see how big of a deal the chiropractic adjustment is?
Subluxation = chronic stress = massive release of stress hormones = disease
Adjustment = decreased stress in the body = health
How is that possible?
There is a particular part of the spinal cord known as LAMINA 7, and it links the spinal cord directly to the HYPOTHALAMUS – the main co-ordinator of all hormones in the body. In fact, the spine has the ONLY direct link to the hypothalamus (and thus hormones) in the entire body!
An adjustment will affect this entire system, bringing the body as a whole back to a state of ease.
