The Blair chiropractic technique used at Cincinnati Upper Cervical and Family Chiropractic is a particular method for analyzing and adjusting the upper cervical vertebrae of the spinal column. When these vertebrae misalign it can disrupt the brain stem and spinal cord as they exit through the floor of the skull and into the neural canal. Particular attention is delivered to the first two cervical vertebrae, the atlas and axis. These are the most freely moveable vertebrae in the spinal column as well as the ones most typically misaligned.
After many years of researching the techniques that were available at the time, Dr. B.J. Palmer (the developer of chiropractic) realized that the only place a person could truly have interference to
the nervous system was at the level of the base of the skull – the atlas and axis vertebrae. There are no intervertebral discs between the skull and the atlas, or between the atlas and axis vertebrae. Most
motions of the head and neck occur at this joint. The joint surfaces at this location move more on a
horizontal plane instead of the vertical plane found in the rest of the spine. This area is not supplied with the wealth of supporting ligaments that are found throughout the rest of the spine. Due to these characteristics of the cervical spine, it becomes the weakest link in the chain when exposed to the forces of trauma such as the falls, stress, birth process, car accidents, etc.
Dr. Palmer carried out studies in Germany finding that the brain stem (medulla), extended into the neural canal down to the level of the lamina of the second cervical vertebrae. Then it becomes the spinal cord extending downward. The brain stem has actually been called “Houston Control” since it is the area where nerve cell centers are located. These control many of the major functions of the body like respiration, digestion, heart beat, elimination, our heating and cooling mechanism, constriction and dilation of the veins and arteries, muscle coordination, etc. Most body functions which aren’t consciously controlled are controlled at the brain stem level.
The brain stem at the level of the atlas vertebrae includes approximately ten billion nerve fibers, all sending messages through the spinal cord to the cells of the body and from the cells back to the brain. These nerve fibers are organized in small bunches called nerve tracts. These nerve tracts are either motor or sensory. The sensory nerves allow us function of the organs and systems while moving the body about it’s environment, via the musculoskeletal system. Gray’s Anatomy states, “the nervous system is the master system of the body controlling and coordinating all the functions of the body and relating the individual to his environment.”
The atlas and axis are the only vertebrae in proximity to the brain stem. When they misalign and put pressure on the spinal cord and/or brain stem, they hinder the vital messages being sent to and from the brain to all segments of the body. For example, if the atlas is impinged against the part of the cord that sends messages to the left hand, that individual may experience burning, tingling, or numbness in that hand. If the nerve tracts at thebrain stem level going to the heart are being impinged, that patient may experience palpitations, high blood pressure, or an irregular heartbeat. Since almost all nerves pass through this area, almost any part of the body can be effected when there is pressure on the brain stem or spinal cord.
When a vertebrae misaligns to the extent that it interferes with nerve tissue and reduces the mental impulses it is termed a subluxation. A subluxation may be present for months or years before producing any outward signs such as pain or symptoms, causing the body to break down to a state of diseases
The purpose of the Blair Chiropractic technique is not to diagnose or treat diseases or conditions, but to analyze and correct vertebral subluxations in an accurate, precise and specific manner to allow the body to mend, repair and maintain health from within.
Cincinnati Upper Cervical and Family Chiropractic, SD utilizes neurological tests, heat sensitive instrumentation, and other means for detecting if the vertebral subluxation is present or absent. An adjustment is administered only when nerve pressure is found. The Blair Chiropractic technique uses precise x-rays of the upper cervical area to determine which way the vertebrae has misaligned. This information is used to create a precise and specific adjustment tailored and administered to that patient.
