Proper spinal alignment is essential for healthy and pain-free living. When a subluxation occurs it causes nerve interference in some portion of the body affected by those nerves. The subluxation causes changes to the structure as well as the nerves. These changes get progressively worse as time is allowed to work on the subluxated area of the spine. These changes take the form of ongoing degeneration known as "subluxation degeneration". By understanding the type and amount of changes, it is possible to reasonably estimate the time subluxations have been present in a spine. Having this information is useful in understanding the time and effort needed for correction.

As these x-rays show, there is a progressive degeneration that can be halted, or slowed, with proper chiropractic care.

NORMAL Proper spinal curves permit normal turning and bending. Openings between joints allow nerve roots to exit the spine without interference. The edges of the bones are smooth and well defined. Equal disc spacing is a sign of healthy spinal function.	PHASE ONE Loss or normal curves and misalignment restrict or exaggerate normal ranges of motion. ligament and muscle strength is reduced. Even with nerve irritation and soft tissue inflammation, pain or other obvious symptoms may not be present.	PHASE TWO Years of accumulated calcium deposition are now visible. Bone spurs attempt to fuse malfunctioning joints. Adjacent surfaces are rough and uneven. Joint instability is accompanied by continued nerve irritation and disc degeneration.	PHASE THREE After years of neglect, complete fusion has immobilized the joint. Obstructed nerve openings cause permanent nerve irritation as soft tissue degeneration continues. This irreversible condition is usually associated with other chronic health problems.
