Since 1998, we have contacted more than 1,000 cases of children aged 3 to 16 with cervical spine dysfunction and more than 100 cases of adolescents aged 16 to 36 with tic symptoms, and found from them that cervical spine dysfunction in childhood is closely related to adult cervical spine disease. What are the “differences” and “similarities” between “cervical dysfunction” and “cervical spondylosis”? The following is an explanation of each. From the point of view of clinical performance, the two have a large “same”, but also has the essence of “different”. In clinical investigation, the symptoms of dizziness, headache, tinnitus, nausea, limb numbness, snoring and lower limb weakness caused by cervical spine dysfunction in children are the same as the complaints and signs of different types of cervical spine disease in adults, just because the expression ability and attention of children are significantly lower than that of adults! Straightening of cervical spine curvature and distorted spinous processes from cervical spine images are also consistent with adults, etc. So it seems that there is so much agreement between cervical dysfunction and cervical spondylosis in children, what is the essential difference? The essential difference between children and adults is that children have not yet grown up, while adults have matured into decline! After 300 cases of children’s clinical observation, the excellent rate of symptom improvement is 92% after 3~6 months of correction, 90% of the cervical spine films have changed after rechecking, 50% have improved, 20% of which are overcorrected and deviated to the other side, 20% of the position is not improved but also aggravated. This indicates that the cervical spine joints are extremely unstable in childhood, so as to produce a state of continuous stimulated excitation of the upper sympathetic ganglion, triggering hyperfunction of the dopamine system and the appearance of the unique manifestations of childhood: muscle twitching and hyperactivity! This shows that the essential difference between the two is that one is a child and the other is an adult! From the perspective of clinical treatment, there are also “differences” and “similarities” between the two. The causes of cervical spine dysfunction in children are mainly twofold: one is the instability of the corresponding joints after cervical ligament injury, and the other is the lack of muscle strength and poor stability of the whole spine as a result of childhood development. In treatment the first requires corrective training, which needs to be performed for more than 3~6 months to restore the normal curvature of the cervical spine and improve the joint relationship of the cervical spine as the goal. The second requires functional training maintenance, which also takes 3~6 months. The most critical measure on this basis is to comply with developmental needs, nutritional support, exercise guidance, prevention of re-injury, and restoration of proper developmental status! The pathological basis of adult cervical spondylosis is disc degeneration, which produces joint instability, muscle strain and ligament strain, and treatment requires joint correction and functional training, which is similar to the treatment plan for cervical spine dysfunction caused by cervical spine injury in children, with the difference that adults place more emphasis on joint stability, and through daily posture correction, combined with functional training, the purpose of stabilizing cervical joints and restoring cervical spine function is achieved. It can be seen that there are differences and similarities between cervical dysfunction in children and cervical spine disease in adults. Children focus more on promoting development and brief treatment to ensure a benign state of development; adults focus on functional rehabilitation and daily maintenance is to improve function.
