After the cervical spine becomes straight, it is difficult and also time consuming to restore the normal physiological curvature of the cervical spine, but the physiological curvature of the cervical spine can be restored to the maximum extent through rehabilitation exercises and other measures. The physiological curvature of the human cervical spine is normally anteriorly convex, but it is not unchanging. As we age, the cumulative damage to the cervical spine will gradually develop degenerative changes, causing the cervical curvature to change and the cervical spine to straighten or even to bend in reverse tension. It is usually possible for young people to recover after improving their living habits, while it is relatively difficult for the elderly. Patients should avoid bad working and living habits in life, do not keep their heads down for a long time, do not work for a long time, do more cervical exercises, swim more and strengthen the functional exercise of the neck muscles. A better cervical pillow should be taken when sleeping so that the muscles of the neck can be relaxed. Physical therapy such as neck massage, traction, massage and acupuncture can also be carried out appropriately to promote blood circulation and improve symptoms. The essence of the cervical physiological curvature straightening is the degeneration of the cervical intervertebral disc, the strain on the muscles in front and behind the cervical spine, and the degeneration of the ligaments, so attention should be paid to changing bad posture and reducing the time spent with the head down.
