Background
Cervical syndrome is called cervical spondylosis for short, and is characterized in that intervertebral instability is caused by cervical degenerative changes caused by acute injuries or chronic strain of neck, shoulder and back, joint dysfunction is caused, or secondary injuries of soft tissues around the cervical vertebra are caused by cervical joint damage caused by hyperosteogeny and the like, wherein the secondary injuries comprise cervical nerve roots, vertebral veins, cervical sympathetic nerves and cervical spinal cords. The clinical manifestations of different diseased cervical vertebrae and different secondary damaged tissues vary greatly. The most common symptoms are intractable localized pain, numbness in the head, neck, shoulders, back and upper limbs, and aggravation of symptoms during sleep, low head labor or neck activity. Most patients have tenderness and induration beside the vertebra, the activities of the head, the neck and the upper limbs are limited, and some patients have rubbing sounds during the activities, accompanied by secondary muscular atrophy or symptoms such as discomfort of eyes, dizziness, nausea, twitching of neck muscles (head shaking), foreign body sensation in throat, stuffy pain in chest and the like. The serious patient is paralyzed and even threatens life. Cervical spondylosis is a common disease and a chronic disease of middle-aged and old people. Cervical spondylosis is a very troublesome disease in clinic because the cervical vertebra is often in motion.
At present, traction beds are adopted at home and abroad to carry out cervical vertebra or lumbar vertebra traction rehabilitation treatment on patients, and a better curative effect is achieved, so that various traction beds are born successively and are widely used in hospitals at all levels. However, the medical traction bed has a complicated structure, is too high in cost and is inconvenient to popularize, patients need to go to a hospital for rehabilitation, and most patients with serious diseases do not want to take special time for treatment, so that the diseases are increasingly serious; and traditional domestic type traction table, the function is comparatively single, and space area is great, is not convenient for accomodate when not needing to use.
