In recent years, school-age adolescents have been suffering from some pathological changes in the cervical spine due to heavy academic workload, prolonged ambulation and low physical activity, resulting in a series of symptoms with neck pain as the main symptom, which affects the study and life of adolescents, and may become cervical spondylosis if not properly treated. According to the patient’s symptoms, there are three types of cervical spondylosis: (1) Qi stagnation and blood stasis: the pain is fixed, the pain is very painful when pressed, or radiates to the shoulder and arm, or is accompanied by numbness of the arm, dark tongue, and string veins. (2) Phlegm obstruction: headache and dizziness, nausea and vomiting, loss of appetite, fullness in the chest and abdomen, white and greasy coating, moist and slow pulse, etc. (3) Liver depression and blood deficiency: mental depression, impatience, loss of vision, drowsiness or insomnia, dreaminess and forgetfulness, lack of concentration, pale tongue with thin coating, thin and stringent pulse, etc. 2.Treatment method Treatment is based on Sun Shuchun cervical spondylosis treatment method finishing rotational brace technique: first relax the shoulder and neck by using loose tendon technique, hold the patient’s jaw with one hand, hold the back of the neck with the other hand and gently rotate and move the cervical vertebrae; finally identify the points to eliminate the symptoms. For the type of Qi stagnation and blood stasis, take Hegu, Quchi, Jiquan, Yingjing, Yu and Fengchi; for the type of phlegm internal obstruction, take Baihui, Sun, Miming, Sansanli, Fengchi and Sanyinjiao; for the type of liver stagnation and blood deficiency, take Yongquan, Sanyinjiao, Sansanli, Miming, Sibai and Tianzong; the patient is treated three times a week for two weeks. Patients were instructed to practice functional exercises for neck flexion and extension rotation for 5 to 10 minutes twice a day, and to pay attention to changing poor sitting posture and increasing physical exercise time. Currently, there is a significant increase in the occurrence of neck pain in school-aged adolescents due to factors such as heavy school workload, poor posture, absence or reduction of physical exercise and outdoor activities. In addition to neck and arm pain, school-age adolescents with neck pain may also suffer from headache and dizziness, loss of vision, insomnia and forgetfulness, lack of concentration and other symptoms, which directly affect academic performance. Neck pain is the main symptom of school-age adolescents with neck pain, and the clinical manifestations are mostly neck and shoulder fatigue and soreness, and some patients may have no obvious conscious symptoms due to the insidious onset. Neck pain in school-aged adolescents is mainly caused by the imbalance in the balance of the cervical mechanics system, and the imbalance in the biomechanical system of the cervical spine due to the instability of the cervical segments and the change in the physiological curvature, which stimulates the surrounding tissues and structures, and thus a series of clinical symptoms. The stability of the human cervical spine is maintained by two aspects. The first is endogenous stability: it includes the static balance of the vertebrae, attachments, intervertebral discs and connected ligaments, which provides the basis for cervical spine stability and limits excessive activity beyond the physiological range. The second is exogenous stability: regulated and controlled by the tension and contraction of the cervical and shoulder muscles, which are the original driving force for cervical spine postural maintenance and movement, and this is the dynamic balance. The cervical muscles are important to maintain the physiological curvature of the cervical spine and the stability of the cervical spine. The movement of the cervical spine is accomplished under the coordinated action of the nerves and muscles, with the active muscles responsible for initiating and completing the movement, while the antagonistic muscles tend to control and correct the movement. The muscles around the cervical spine are necessary to maintain its stability, maintain posture, and provide movement, and well-developed muscles enhance the stability of the cervical spine. The various factors that lead to chronic neck strain in adolescents put the neck in an uncoordinated muscular position for long periods of time, and the function of the power and antagonist muscles decreases due to resistance fatigue, resulting in a dysfunctional dynamic balance of the cervical spine. With the increased tension of the neck muscles, muscle tension and spasm further lead to their abnormal metabolism, which causes the weakening of the neck muscles over time, thus leading to the destruction of exogenous stability. Abnormal cervical muscle strength puts the cervical spine under the action of non-equilibrium forces for a long time, which inevitably leads to cervical segmental instability and changes in physiological curvature resulting in a comprehensive cervical biomechanical imbalance, which in turn leads to anatomical and histological changes. Most of the X-ray manifestations of neck pain in school-aged adolescents are abnormal cervical physiological curvature and asymmetry of the annular pivot joint, with a higher number of abnormal cervical physiological curvature. School-age adolescents are in the period of physical growth and development, and they belong to the so-called “childish yin and childish yang” body in Chinese medicine, which is angry and flexible. In the choice of treatment method, orthopedic manipulation can be used, here we use according to Sun Shuchun cervical spondylosis treatment method finishing rotating tor wrenching manipulation, first loosening tendon manipulation to relax the shoulder and neck, then one hand to hold the patient’s jaw, the other hand to hold the back of the neck, gently rotating and moving the cervical spine, adjusting the anatomical position of the unstable cervical spine thus can fundamentally change the pathological changes of the cervical spine. In addition, the patient’s symptoms can be targeted to be relieved by relaxing the excessive muscle tension in the neck and adjusting the coordination and balance of the neck muscle groups with the use of acupuncture points. The treatment of adolescent neck pain by using the rotational brace wrench technique according to the cervical spondylosis treatment technique has good effect, and not only the symptoms can be relieved through the treatment, but also the disc degeneration and secondary lesions can be reversed, and the X-ray performance can be restored to normal. Conclusion (1) Neck pain in adolescents has become a frequent disease in the school age, which should attract the attention of parents and relevant departments. (2) The nature of the lesion of adolescent neck pain should be functional change, which is reversible, and the pathological changes of the neck can be restored to normal with reasonable intervention methods. (3) The naming of the disease is still debatable. Since the cervical instability is the main cause, we suggest that it can be called: adolescent cervical instability syndrome.
