First, from the anatomical and physiological point of view of cervical spondylosis, the cervical spine is more active than the thoracic and lumbar spine, and the frequency of activity is also higher. The cervical spine has to perform forward flexion, back extension, left and right lateral flexion, left and right lateral rotation, rotation and compound movements in all directions, while the supporting structures of the cervical spine are weaker than those of the thoracic and lumbar spine. The thoracic spine is supported by the thoracic and dorsal muscles, and the lumbar spine is also supported to a certain extent by the lumbar muscles and the pelvis, etc. In addition, structures such as the posterior joints of the cervical vertebrae are weaker than those of the thoracic and lumbar vertebrae, and are therefore less stable than those of the thoracic and lumbar vertebrae. Once the contradiction between high mobility and low stability loses its coordination and balance, i.e. excessive neck activity or certain factors induce neck instability, it will cause the recurrence of cervical spondylosis.
