The Subluxation/Spinal Joint Dysfunction

Whether you just started seeing a chiropractor or are a long-time patient, you’ve probably heard the term “subluxation.” Your chiropractor may have also used the terms vertebral subluxation complex or spinal joint dysfunction . Generally speaking, these terms are interchangeable. However, subluxation has specific qualities to chiropractors and is a word with historical significance.

By definition, subluxation describes a spinal joint (a joint between two vertebrae) or peripheral joint (a joint other than the vertebral joints, like one in your foot or wrist) that is relatively immobile (has restricted motion) or abnormally positioned. An analogy may be as follows: If you have a steering wheel that is stiff and that does not turn all the way, it is “subluxated” and can lead to an accident. The wheel needs to be oiled so that it is loose and moves to its full capacity, helping you to steer properly.

Subluxations can cause local pain and may interfere with or impede the function of the nervous system, joints and muscles. This may decrease the body’s ability to heal and function optimally.

There are generally five components of subluxation, which fall under the broader heading of the vertebral subluxation complex (VSC). These components generally occur sequentially in the following order:

1. Abnormal spinal mechanics Your chiropractor will use his or her hands to assess the movement of your spine or peripheral joints. When a joint is not moving well relative to the joint above or below it, it is said to have abnormal spinal mechanics. This may result from trauma, like a fall, or from chronic mistreatment, like poor posture. If you have abnormal mechanics, you may notice a lack of mobility, such as difficulty moving your head to check your rearview mirror. If not cared for, this can lead to abnormal nerve function. Your chiropractor will use adjustments to restore the restricted motion.

2. Abnormal nerve function Whenever a subluxation does not heal properly there will be a pinched or irritated spinal nerve. That’s because the spinal facet joint is located adjacent to the spinal nerve roots, and sprained spinal joints irritate the roots either by direct pressure (only about 10% to 15% of the time) or by irritation with inflammatory chemicals (85% to 90% of the time). In addition, when the joint is sprained or subluxated the tiny nerve endings in the joint’s cartilage may become damaged. If this happens, it can alter the messages nerves send to the brain and affect the brain’s ability to control the spinal muscles.

3. Abnormal muscle function Whenever there are pinched or irritated spinal nerves there will usually be muscle problems. Pinched (impinged) nerves will cause muscle weakness, whereas irritated nerves may cause muscle strain or spasm. This can lead to muscle inflammation and eventually scar tissue formation or gristle in the muscle. To patients, this feels like tight or rope-like muscles, which are tender to touch. In addition, patients may notice that their muscles burn and tire easily. Left unchecked, this inflammation can spread throughout the spine.

4. Abnormal function of soft tissues around the spine Inflammation that occurs in muscles and joints can cause further complications by spreading to all areas around the spine. With long-term swelling of structures, such as ligaments, disks and other soft tissues, calcium and fibrous materials are laid down. With repeated episodes of subluxation, the spine accumulates an increasingly larger number of abnormal sites. In fact, some MRI studies have shown areas of soft-tissue fibrosis and calcification up to one inch thick around the spine. At the same time, long-term swelling can increase due to improper vascular supply and drainage. From here, full-blown spinal disease is the likely outcome.

5. Disease at the spinal level and of the whole body At this stage, irreversible disease or pathology can occur. This may manifest in the spinal area as bony spurs on the vertebrae, decreased disk height and roughened joint surfaces. Known as osteoarthritis or subluxation degeneration, it can occur at any age, but is increasingly common as people get older. In addition, it can lead to disease or pathology away from the spine, in all body tissues, organs and systems.

Muscle Balancing in Applied Kinesiology

As a Doctor of Chiropractic, I know that muscle balancing is an important not only for spinal adjustments but also for extremity (arms & legs) adjustments and cranial adjustments.

 For example, I can adjust someone’s spine but if the pull of the muscle on one side of the spine is tighter than the other side than that spinal adjustment will not hold.

 Now most people think that it’s the tight muscle that will pull the spine out of alignment but it just as often can be the weak muscle not having enough strength to hold the spine towards its side.

 Also I may be treating a patient who has chronic muscle pain or weakness due to an injury; in these cases, muscle balance is very important.

 In Applied Kinesiology, we have ways to strengthen or weaken a muscle depending on what we need to do to help the patient.

 First we test the muscle that we think may be involved in an unbalanced pull on the bone (or spine) or involved w/ the pain or injury https://drvittoriarepetto.wordpress.com/2010/05/06/the-art-and-science-of-muscle-testing-in-applied-kinesiology/

testing rectus femoris

 For example, we may find the latissimus dorsi muscle weak that is a muscle that internally rotates, extends and adducts (movement towards from the body) the arm/ shoulder. It also attacts into the lumbar and sacral vertebra and part of the pelvic crest The weakness may seen either as a higher shoulder on the weak side or a rotation of the lumbar veretebrae.http://www.meddean.luc.edu/lumen/meded/grossanatomy/dissector/mml/lat.htm

The questions to be asked are: why is the muscle weak? Is the muscle on the other side hypertonic  or “too stronger.”

 One of the ways to find the answer is to use muscle spindle work. Muscle spindles are small sensory neuro-bundles in the middle of muscles that react to stretching. http://sports.jrank.org/pages/9926/muscle-spindle.html  Stretch a muscle spindle one way and the muscle will strengthen; push the fibers of the muscle spindle the other way and the muscle will weaken.

 So I would be testing the spindles by challenging the muscle spindles and seeing how it affects the strength or hypertonicity of the muscle.

 I can also use another tool at an Applied Kinesiologist’s fingertips which are golgi tendon organs and as the name suggests, these are located in the tendons of muscles (tendons attach the muscle to the bones.). http://medical-dictionary.thefreedictionary.com/Golgi+tendon+organ. Again stretching the tendon organ will help strengthen the muscle and the other way will weaken it. And these would be tested in a similar manner to the muscle spindles.
