Cervical spondylosis refers to the degenerative changes in the cervical discs, cervical joints, cartilage, ligaments, muscles and fascia and their secondary changes, resulting in damage to the spinal cord, nerves, blood vessels and other tissues, such as compression, irritation, instability, etc. The resulting series of clinical symptoms are called cervical spondylosis. Cervical spondylosis occurs in adults between the ages of 40 and 60, and is more common in men than in women. The affected person often feels pain in the head, neck, arm, hand and forehead, and may have progressive limb sensory and motor disorders, or in severe cases, weakness of the limbs, even incontinence and paralysis. Cervical spondylosis is a degenerative disease. The main and most direct causative factor is that the cervical spine is in a flexed position or certain specific positions for a long time, especially long-term head-down work, which not only increases the pressure in the cervical intervertebral disc, but also puts the neck muscles in a long-term uncoordinated stress state. The muscles and ligaments in the back of the neck are easily strained and damaged, and the front edges of the vertebrae are worn and proliferated to each other, which, together with the excessive twisting and lateral flexion, further leads to injury and easy occurrence of cervical spondylosis. So the main prevention of cervical spondylosis is to slow down the process of cervical disc degeneration, you can start from the following aspects. 1, improve the sleep state people have 1/3 time a day in bed, improper sleep posture will intensify the pressure in the cervical disc, so that the ligaments and muscles around the cervical spine fatigue, triggering cervical spondylosis. In order to maintain the normal physiological curve of the cervical spine in sleep, attention should be paid to several points: (1) pay attention to the use of a suitable pillow. The pillow is an important tool to maintain the normal position of the head and neck. This “normal” position is to maintain the physiological curve of the head and neck section itself. This physiological curve not only ensures the balance of the external muscles of the cervical spine, but also maintains the normal physiological anatomical state of the spinal canal. Pillow texture to be soft, breathable, should not be too high too low, to 8 ~ 15 cm high is appropriate, do not “high pillow”. The shape of the middle is low, both ends of the high yuan Bao shape is better, the advantage of this shape is that the neck can play a relative braking effect. (2) sleep position should make the chest, waist-like hold natural curvature, double marrow, double knee is flexed, so that the whole body muscle relaxation. (3) The bed should be chosen to maintain the balance of the spine, the mattress with a wooden board as the bottom is better. 2.Correct bad position Cervical degeneration is closely related to the cervical spine in flexion or a specific position for a long time. Bad body position will lead to a series of symptoms caused by the increase in the intervertebral disc. (1) Regularly change the cervical spine position. That is, when the head is turned in one direction for too long, it should be turned in the other opposite direction and repeated several times in a short period of time, which is conducive to neck health care, but also to eliminate fatigue. (2) Regular farsightedness. Looking down for a long time, not only affect the cervical spine, but also easy to cause vision fatigue, and even lead to myopia. Therefore, when working too long, you should look up for about half a minute, which is conducive to relieving neck muscle tension, but also eliminate eye fatigue. (3) adjust the height and tilt of the desktop. If the table is too high or too low will make the neck supination or flexion, both positions are not conducive to the internal and external balance of the cervical spine. Can be made with the desktop is 10 degrees ~ 30 degrees oblique work plate, ambulation work can reduce the cervical flexion and cervical interstitial pressure. (4) to pay attention to the development of interval exercise activities. This for long-term ambulatory workers, not only can make the limbs and viscera benefit, to regulate the cervical spine and the entire spinal balance is also very beneficial.
