Cervical traction therapy is an effective treatment measure used clinically. The therapy is simple and convenient and can be performed by patients in hospitals, at home or during leisure time such as work breaks. Its main functions are: 1. It has a braking effect on the head and neck. 2.It can widen the intervertebral space by traction, so that the pressure inside the intervertebral disc is reduced, so the nucleus pulposus or fibrous ring compressing the nerve roots and spinal cord is reduced, which helps the edema of the nerve roots and spinal cord to subside. 3.The relatively narrowed intervertebral foramen can be enlarged by stretching, thus relieving the compression and irritation of the cervical spinal nerve roots. 4.The release of the compression on the nerve relieves or relieves the painful spasm of the cervical muscle. 5.By pulling each joint of the cervical spine, the dislocated intervertebral joints are promoted to reset, so that the anatomical relationship can be restored to normal. 6.Through pulling, the bending and twisting of the vertebral artery can be restored and the blood supply to the neck can be improved. Cervical spine traction usually choose the occipital chin sling traction method, the efficiency is more than 90%, sitting or supine position, head tilted forward 15º, weight 2~8kg, depending on the condition and weight, can be gradually increased from a small amount, generally start preferred 2~4kg, then according to the patient’s weight and self-feeling appropriate increase or decrease weight, if traction after feeling symptoms significantly improved, feel comfortable, that is The most weight should not exceed 10kg to prevent injury. At the beginning, 1 time/2h, gradually increase to 1 time/1h, 1~2 times a day, 3~4 weeks as a course of treatment, effective person can increase 1 course of treatment. The duration and course of each traction should be determined according to the condition and should not be too short. Even if the symptoms are relieved or disappear faster after traction, it should not be terminated prematurely, and the author’s experience should maintain traction for about 3 months to reduce recurrence. According to the X-ray measurement results, the average widening of the posterior edge of the intervertebral space can be 4.0mm when traction is performed in the middle position with 10kg of weight in a seated occipital chin sling, so attention should be paid to the forward tilt of the head during traction.
