Decreased Mobility of the Spine: Degenerative Disc Disease & Scoliosis
Each section of the spine has its own degree of mobility. The sections with the greatest mobility are the cervical (neck) and lumbar (lower back) areas. The thoracic spine area (from the bottom of the neck to the base of the rib cage) is relatively mobile. The sacrum (the area just above the tailbone) and coccyx (the tailbone) cannot move at all. In many cases, limited mobility is a protective reaction of the body, which means the body tries to prevent the spine from being exposed to excessive stress and injury. Decrease in the ability to move often occurs following an injury.
Mobility may decrease slightly, as it does in the early stages of degenerative disc disease and scoliosis. It may also virtually disappear, as it does, for example, in diseases like ankylosing spondylitis, ankylosing hyperostosis.
When this condition occurs, the patient cannot turn just one section of the spine, he or she has to turn his whole body. It is also difficult to stoop, so they prefer to crouch down.
