Cervical spondylosis, also known as cervical spine syndrome, is a combination of a series of clinical symptoms and signs resulting from degenerative changes and secondary changes in the cervical discs, cervical joints and their associated muscles, ligaments and fascia, which stimulate or compress the surrounding spinal cord, nerves, blood vessels and other tissues. The incidence of cervical spondylosis increases significantly with age. In recent years, a survey shows that the incidence of cervical spondylosis among adolescents in China is increasing year by year. The clinical manifestations are mostly numbness and pain in the head, neck, shoulder and arm, and weakness of the muscles. When the lesion involves the vertebral artery, sympathetic nerve and spinal cord, symptoms such as dizziness, panic, urinary and fecal incontinence and paralysis appear. Common causes include: 1. Wind, cold and damp factors. The wind, cold and damp factors in the external environment can reduce the body’s tolerance to pain, which can cause muscle spasm, small blood vessel constriction, slow lymphatic flow, and impaired blood circulation in soft tissues, followed by sterile inflammation. 2.Strain injury. Long-term so that the head and neck in a single position position, such as prolonged low work, prone to cervical spondylosis. 3, bad posture. Such as lying in bed watching TV, reading books, high pillow, sleeping in a sitting position, etc.; sleeping on a recumbent car, poor muscle protection when sleeping, easy to neck injury when braking. 4, head and neck trauma. 50% of medullary cervical spondylosis is related to neck trauma. Some patients with cervical spine osteophytes, disc herniation, soft tissue lesions in the spinal canal, etc. make the cervical spinal canal in a narrow critical state, neck trauma often triggers the symptoms. For the above causes usually life to do self-care cervical spine for the prevention of cervical spondylosis often play an unexpected effect, mainly the following: 1, winter should pay attention to the neck warmth, summer to avoid air conditioning, fans blowing directly on the neck, to avoid wind cold wet invasion. 2, a reasonable pillow, cervical spondylosis patients exist physiological arc straightening, disappearance or anti-arch, physiological arc too large and other imaging performance, so the physiological arc straightening disappeared when lying supine pillow should be pillowed in the cervical collar, so that the neck to maintain the physiological arc. The physiological arc is too large, should be pillowed in the back of the pillow. 3, in the sitting posture, to maintain a natural sitting position as far as possible, adjust the height ratio between the table and chair, avoid excessive head and neck backward or forward, forward flexion, so that the head, neck, shoulders, chest to maintain the normal physiological curve, correct poor posture, reasonable neck, avoid reading, watching TV leaning on the sofa, or half lying half leaning on the head of the bed; should not be overly fatigued, low head ambulation work for 2 hours should be rested 10 -15 minutes, it is advisable to look up and rub the neck with your hands; computer monitors are placed in the middle or left and right, the monitor screen should be high and not low, the keyboard should be high and not low, the mouse should be near and not far, low and not high, the use time should not be too long. 4, should often carry out functional exercise of the neck, after working for a period of time, generally in about 30 minutes, so that the head and neck to the other direction of rotation, the opposite direction of rotation should be gentle, slow, to avoid rapid activity of the cervical spine, repeated several times in a short period of time, in order to achieve the maximum range of motion in this direction is better, to the extent possible, stop, do not over exercise damage to muscle ligaments.
