Straightening of cervical curvature can be gradually adjusted and corrected to a certain extent through treatment if the patient is young and has good joint and muscle toughness, but it is generally not easy to recover from it if the patient is old and the cervical vertebrae have degenerated. Normal human cervical spine has 20 ° ~ 25 ° anterior convex physiological curvature, which is conducive to alleviate the cervical intervertebral disc load and shock, reduce the cervical intervertebral disc load as well as the load of the vertebral body, but also to maintain standing, walking, looking straight ahead plays a role. If the posture is inappropriate for a long time, it will lead to degeneration of the cervical vertebrae, the cervical vertebral convexity gradually disappears, and the cervical curvature becomes straight or even inverted. This will cause neck pain, stiffness, dizziness, nausea, and numbness of the upper limbs and other symptoms. When the cervical curvature straightening, in daily life, to correct the bad posture, you can do cervical spine exercises, neck muscle function exercise, etc., is conducive to the blood circulation of the neck, release muscle spasm, improve the cervical curvature straightening. In the elderly, due to the degeneration of the cervical vertebrae and the decline of muscle strength, the cervical curvature of the cervical vertebrae is straightened, and it may be difficult to adjust it back under normal circumstances. Patients with straightened cervical curvature who experience discomfort should consult a hospital in time and under the guidance of a physician for standardized treatment to avoid gradual aggravation of their condition.
