Straightening of the neck indicates that the physiological curvature of the cervical spine has basically disappeared, and the cervical spine is flat and straight, which indicates that preliminary cervical spondylosis has occurred, and if it is more serious, it will also be accompanied by nerve root irritation and injury symptoms. At this time, it is necessary to avoid the negative triggers that lead to the straightening of the cervical spine to continue to play a role in correcting the negative triggers, such as prolonged low head work, the use of cell phones, the use of computers, etc., and at the same time, should strengthen the cervical vertebrae function exercise. Once the strength of the neck muscles and the quality of the fascia are improved, the symptoms of neck pain will improve significantly. If more ideal, the physiological curvature of the cervical spine will also reappear, greatly delaying the occurrence of cervical spondylosis. Therefore, when the cervical spine becomes straight, it is important to avoid adverse triggers and strengthen functional exercises.
