Why do chronic strain injuries lead to cervical spondylosis? Chronic strain injury refers to a variety of activities that exceed the maximum of the normal physiological range of motion or when the local area can tolerate it. Because it is different from obvious trauma or accidents in life and work, so it is easy to be ignored, but in fact, it is the most important factor constituting the degeneration of the cervical spine bone and joint, and has a direct relationship with the occurrence, development, treatment and prognosis of cervical spondylosis, such strain mainly includes: 1, bad sleep position about 1/3 to 1/4 of a person’s life spent in bed, so bad sleep position because of its The long duration, because the resting brain can not be adjusted in time, is bound to cause the paravertebral muscles, ligaments and joints of the balance disorders. The side with large tension is easily fatigued and leads to different degrees of strain injury, and the early symptoms caused by the imbalance outside the spinal canal are mostly “neck and shoulder pain” after waking up. The common feature of the above habits is that the cervical spine is in a state of flexion for a long time, and the muscles and ligaments behind the neck are overloaded for a long time, which can easily cause strain injury. 3, poor work posture involving computers, microscopes, carving, embroidery and other staff also need to work for a long time with their heads down. In the flexed neck state, the pressure of the intervertebral disc is much higher than the normal position, this position is easy to accelerate the degeneration of the intervertebral disc and soft tissue strain in the neck. 4, inappropriate physical exercise Normal physical exercise helps health, but more than the neck endurance activities or sports, such as American soccer (available overhead ball), with the head and neck weight of the human body inversion or somersault, can increase the load on the cervical spine, especially in the absence of proper guidance, such as once the accident caused trauma is more serious consequences. In addition, certain folk head and neck practice method, the cervical spine has degeneration should not be advocated, otherwise not only can aggravate the degenerative changes of the cervical spine, and even accidents can occur, especially the spinal cord has been compressed symptoms should be completely prohibited.
