The white-collar class of people engaged in office work, due to long-term head-down work, so that the cervical spine for a long time in a flexion position or some specific position, not only to increase the pressure in the cervical intervertebral disc, but also to make the neck muscles in a long-term non-coordinated stress state, the back of the neck muscles and ligaments are susceptible to strain strain, the front edge of the vertebral body mutual wear, hyperplasia, coupled with torsion, lateral flexion, and further lead to injury, easy to occur Cervical spondylosis. Office workers first in the sitting position as far as possible to maintain a natural sitting position, head slightly forward, to maintain the normal physiological curve of the head, neck and chest, for long hours of work, should be in about 1 to 2 hours, purposely let the head and neck to the left and right several times, the rotation should be gentle, slow, to achieve the maximum range of motion in this direction shall prevail. Secondly, strengthening the exercise of the back of the neck muscles is one of the effective ways to prevent cervical spondylosis. The muscles of the back of the neck are an important structure for maintaining the stability of the cervical spine, and the exercise of the muscles can slow down the process of degeneration of the cervical spine strain and reduce the stimulation of the spinal cord, nerve roots, sympathetic nerves and vertebral arteries in the neck by bone spurs. The method is to sit with your back against the wall, raise your head, and push your head back against the wall with the head and body not moving, but only the muscle tension contraction, called muscle isometric contraction. During the exercise, the muscles in the neck continue to be tense for 3-5 seconds and relax for 3-5 seconds for one cycle, that is, one time. In this way, exercise 100-200 times a day, in 3-5 groups to complete. You can also lie prone on the bed, remove the pillow, lift the chest with force, make the head, neck and chest leave the bed for 3-5 seconds, then relax the muscles, put down the head, neck and chest to rest for 3-5 seconds for 1 cycle, exercise 50-100 times a day, in 3-5 groups to complete. Patients can choose the appropriate method for their own exercise according to their actual situation.
