How to self-test whether the cervical curvature is normal?

People with normal cervical curvature can usually stretch their backs, and their faces are almost parallel to the ceiling; The flexion test showed that the mandible clung to the sternum. Curvature test, the earlobe is directly above the acromion to test whether the curvature of cervical vertebra is normal.

Symptoms caused by cervical curvature change:

1, neck and shoulder muscles ache

Due to the change of physiological curvature, the vertebral bodies of cervical vertebrae are rearranged, and the muscles around cervical vertebrae are also changing to adapt to the new balance. The anterior cervical muscle contracts and the posterior cervical muscle expands, which leads to neck and shoulder muscle strain and neck and shoulder pain and discomfort.

2, the change of mechanical structure, easy to cause disc herniation.

The order of cervical vertebrae changes, and the neck muscles lose balance, which makes it difficult to maintain the original balance of cervical vertebrae, forming a vicious circle, leading to cervical dislocation and disc herniation, which is easy to cause compression of vertebral artery, nerve root, sympathetic nerve and even spinal cord. There are corresponding symptoms, such as numbness of upper limbs, dizziness and nausea.

Methods to prevent the physiological curvature of cervical spine from straightening

1, prevention of trauma and stiff neck

At ordinary times, it is necessary to prevent neck trauma and stiff neck, avoid cervical ligament injury, destroy the stability of cervical spine, and further induce or aggravate cervical spondylosis.

Step 2 strengthen neck exercise

Strengthening neck exercise can prevent and delay the occurrence and development of cervical diseases. Try to keep a natural sitting posture, with your head slightly forward, and keep the normal physiological curve of your head, neck and chest; The height ratio between the desktop and the chair can be raised or lowered to avoid excessive backward or forward flexion of the head and neck; In addition, it is more beneficial to adjust the sitting posture by customizing an inclined working board at 10 ~ 30 degrees with the desktop.

Secondly, the head and neck should rotate around 1 ~ 2 hours, and the rotation should be gentle and slow to achieve the maximum range of motion in this direction; Or do a shoulder pinching exercise, slowly tighten your shoulders for 3 ~ 5 seconds, then stand up for 3 ~ 5 seconds and repeat for 6 ~ 8 times.
