- Any joint under an elevated stress over some period of time will produce a restrictive response from the body, including some or all of the following; muscle tension adaptations, joint capsule changes, neurological irritations, bone growth changes and compensatory positioning by surrounding joints and muscles.
- Elevated stress can be due to architectural, biochemical, emotional or biomechanical imbalances, producing microstresses over time. It can also be due to a macrostress, such as a slip or fall, auto accident or any other traumatic injury.
- Any joint under increased micro or macro stresses, if left unattended, will at some point become “fixed” relative to the normal mobility that occurs in a normal functioning motor unit of the spine.
- This fixation of a joint will produce a physiological change in that joint over time, including one or more of the following; joint degeneration, restricted range of motion, neurological irritation and a compensatory response from surrounding joints and muscles.
- Much research has been done on “pain” associated with regions of fixation and degenerative changes. There is no direct correlation between fixation or degeneration of a joint and pain.
- However, fixation and degeneration of joints are the precursors to tissue adaptations in the body, and a restricted range of motion, shortening of involved muscles, reduced neuromusculoskeletal function and ultimately, symptoms predictably will result from joint fixation and degeneration.
- The symmetry of the feet, primarily the medial arches, is critically important in producing a biomechanically balanced structure.
- Joint function can be impaired, or compromised, with imbalances in one or both
feet, relative to a foot with normal and healthy medial, lateral and transverse
- Center of gravity of the structure is a critical standard of measurement when
predicting potential of fixation and degeneration of joints.
- Center of gravity is influenced primarily by the eyes, the feet and the biomechanics of the structure, including joint and muscle weakness and joint fixation/degeneration.
- If joint fixation and structural center of gravity are left unattended, there will be
an acceleration of breakdown and loss of function, as well as a cascadelike
“breakdown” effect throughout surrounding joints, nerves and muscles over time.
- The compensatory effect throughout an entire structure can produce elevated joint
stress in noncontiguous regions, or regions not immediately surrounding the
primary sight of fixation.
- A chiropractic adjustment is a passive mobilization of a joint producing minimal
to maximal physiological benefits.
- A mobilized joint has the ability to absorb and disperse stress more efficiently
than a fixated or degenerated joint.
- A fixated or degenerated joint has a reduced ability to disperse stresses, producing
an adaptive response (accumulation of stresses) from the surrounding tissues.
- Acute injuries of the neck and low back are more closely associated with fixated
or degenerated joints, and will require a longer recovery time than an injury to
joints with good mobility
