What Occurs in the Brain during a Chiropractic Adjustment?
Research published in the Journal of Manipulative and Physiological Thera-peutics in 2007, shows how chiropractic helps affect brain and nerve system function. The New Zealand Chiropractors Association states, “Ground-breaking research has, for the first time, identified the actual changes that occur in the body, the nervous system and the brain during chiropractic spinal adjustments.”
The study demonstrates that chiropractic care sends signals to the brain that change the way the brain controls muscles. Researchers commented, “The process of a spinal adjustment is like rebooting a computer. The signals that these adjustments send to the brain, via the nervous system reset muscle behavior patterns.” This is the first time that anyone has used EEGs to prove that there are definite changes to the way the brain processes information after chiropractic care.
Can Chiropractic Support a Condition Like Depression?
A research study published in the November 7, 2005 issue of the Journal of Vertebral Subluxation Research, showed a positive result in the care of individuals with depression. For the purpose of this study subjects were selected on the basis of being over 18 years of age and having depression noted in their medical history file. Fifteen
participants completed the study. The subjects of this study were given a standardized test known as the Beck Depression Inventory (aka BDI-II) both before and after receiving specific chiropractic care for correction of subluxations. The results showed a significant improvement of the average BDI-II scores of the group. On an individual basis, eleven participants experienced marked improvement; two had minimal improvement while only 2 participants scored worse on the follow up test. The researchers noted that this research tested and supported the hypothesis that the chiropractic correction of subluxations reduced the symptoms of depression.
Studies using the electroencephalogram (EEG) show that before and following a chiropractic adjustment those areas of the brain that produce neurotransmitters demonstrate more normalized brain wave maps and increased Alpha waves, associated with a relaxed or meditative states.
Chiropractic and the Brain… Is This a New Concept?
Absolutely not! Chiropractic has always been about re-establishing normal nerve signaling between the brain and the body. In fact, in the early years of chiropractic, the profession purchased several mental institutions. Chiropractic adjustments were the dominant clinical services provided along with healthy garden fresh foods. One of these was located in Davenport. In 1922, the Chiropractic Psychopathic Sanitarium was established. The facility was later known as Forest Park Sanitarium. They were so successful with “mental disorders” that one North Dakota Judge A. W. Ponath noted that at the North Dakota state mental hospital, the “cure and discharge rate” ranged from 18-27%, compared to 65% at Forest Park. Sadly, both Forest Park and Clearview Sanitarium closed in large part due to third party (insurance) refusal to pay for anything other than pharmaceutical and radical electro-surgical care.
Chiropractic and The Flow of Cerebrospinal Fluid (CSF)
Cerebrospinal fluid (CSF) is a clear colorless bodily fluid found in the brain and spine. It is produced in the choroid plexus of the brain. It acts as a cushion or buffer for the brain’s cortex, providing a basic mechanical and immunological protection to the brain inside the skull, and it serves a vital function in cerebral autoregulation of cerebral blood flow. We also know that the flow of CSF affects the distribution of neurotransmitters.
The CSF occupies the subarachnoid space (the space between the arachnoid mater and the pia mater, layers called meninges that surround the brain and spinal cord) and the ventricular system around and inside the brain and spinal cord.
It has long been held that disorders of CSF flow (called CSF stasis) affect the distribution of neurotransmitters; disrupt blood flow (and nutrition to cells) as well as disrupt proper brain function. New research by Drs. Vincent and Carmine Esposito has discovered that there is an improvement in cerebrospinal fluid flow after a chiropractic adjustment. Using before and after MRI studies they have shown dramatic increased of CSF flow around brain and down the spinal cord.
