V. Strang, D.C., describes several hypotheses on how a misaligned vertebra may cause interference to the nervous system in his book, Essential Principles of Chiropractic: [24] Nerve compression hypothesis: suggests that when the vertebrae are out of alignment, the nerve roots and/or spinal cord can become pinched or irritated.
As a result, the cervical spine become misaligned and produces direct spinal cord irritation creating tighter muscles on one side of the body [24] Neck braces can help temporarily. Surgery is required if needed. Non-surgical treatment, to realign spinal misalignment, is corrected by a chiropractor.
The atlas is the topmost vertebra and the axis (the vertebra below it) forms the joint connecting the skull and spine. The atlas and axis are specialized to allow a greater range of motion than normal vertebrae. They are responsible for the nodding and rotation movements of the head.
Age. The risk of most causes of joint pain increases with age. This may be due to increased wear and stress on joints over time and a higher likelihood of other underlying medical conditions ...
A chiropractic adjustment intends to affect or correct a vertebral joint's alignment, motion, and/or function. Specifically, adjustments are intended to correct "vertebral subluxations", a non-scientific term given to the signs and symptoms that are said by chiropractors to result from abnormal alignment of vertebrae.

In contrast to a luxation, which is a complete separation of the joint, a subluxation often returns to its normal position without additional help from a health professional. [6] An example of a joint subluxation is a nursemaid's elbow , which is the subluxation of the head of the radius from the annular ligament .
Craniocervical instability (CCI) is a medical condition characterized by excessive movement of the vertebra at the atlanto-occipital joint and the atlanto-axial joint located between the skull and the top two vertebra, known as C1 and C2.
The distance between the atlas and the occipital condyles, the atlanto-occipital interval (AOI), should measure less than 4 mm, and is better assessed on coronal images. [ 4 ] The Powers ratio was formerly used, which was the tip of the basion to the spinolaminar line, divided by the distance from the tip of the opisthion to the midpoint of the ...
