The methods of cervical spine orthosis include continuous traction, rotational and diagonal repositioning, and functional exercises. 1. Continuous traction: when there is a small joint misalignment in the cervical spine, the cervical spine can be gradually stabilized by traction, so that the muscles on both sides of the cervical spine can relax, and the misaligned joints can be gradually reset by prolonged traction. 2. Adopting the method of rotating the inclined plate type of reset: first of all, we should locate the diseased segment, do appropriate traction on the head and neck, and after traction, we need to use our hands to hold the spinous process of the diseased cervical vertebrae, and then adopt corresponding orthopedic manipulation to make it reset in a short time. 3. Functional exercise: the anterior and posterior stretching, lateral stretching, and the neck against the exercise of the cervical vertebrae have a certain effect on the reset of the cervical vertebrae. Cervical spine should be operated by a professional doctor, do not blindly deal with it on your own.
