In today 's social environment, the risk of mental health among adolescents continues to increase. Many children suffer from emotional disorders and long-term somatic symptoms. The more common situations are : fatigue in daily learning and life, chronic pain in various parts of the body, and autonomic nervous discomfort. Physical discomfort will not only weaken the enthusiasm of adolescents to participate in daily activities, but also hinder the subsequent clinical rehabilitation. Routine psychological intervention and drug therapy can play a certain role in the mental health problems of adolescents, but it is not obvious to alleviate the symptoms of somatization and promote the ability of adolescents to develop a long-term self-regulation of emotions.

    As a trend of systemic aerobic exercise, street dance itself has the following unique advantages over other traditional sports : First, street dance movements are coherent and varied, which can effectively mobilize the whole body muscle group, improve the coordination ability, flexibility and cardiorespiratory endurance of young people ; second, the free performance form of street dance does not limit the fixed action routines, and teenagers can express their inner feelings by following the music rhythm through street dance. The form of choreography performance can strengthen the positive communication with peers and gradually build self-confidence. Different from the boring and monotonous rehabilitation training, the street dance movement has its own trend attribute, which can promote the enthusiasm of young people to participate, especially for young people with emotional disorders, and encourage them to continue to participate in the street dance movement intervention.

Based on this, we focus on the mental health of adolescents. The purpose of this study is to test whether the structured street dance intervention program can help adolescents reduce the persistent physical and mental distress caused by negative emotions and alleviate the intensity of somatization symptoms caused by psychological disorders. It is hoped that the intervention of structured street dance can gradually help teenagers stabilize emotional fluctuations, strengthen positive self-perception, and establish a healthy and good psychological environment. At present, there are some limitations in the clinical intervention methods available for this aspect. However, the threshold of street dance is low and the acceptance of teenagers is high. If the effectiveness of street dance intervention is certified, it can be used as an auxiliary treatment method for daily treatment plan, adding a safe and interesting auxiliary rehabilitation method for clinical treatment, and can be widely promoted in campus and community.

    The research process is as follows. First, we selected the pre-test and post-test quasi-experimental design, and the subjects covered 30 subjects. The subjects were adolescents diagnosed with emotional disorders and accompanied by somatization symptoms. According to the physical function of the subjects, we arranged a structured street dance exercise intervention. The whole intervention cycle lasted for 12 weeks, with two activities per week and a single activity duration of 45 to 60 minutes. We used Patient Health Questionnaire-15 ( PHQ-15 ), Self-rating Depression Scale ( SDS ) and Self-rating Anxiety Scale ( SAS ) to collect data from patients before and after the intervention. On the basis of the data, the subjects were analyzed at three levels : somatization, depression and anxiety. For the analysis and processing of data, we use independent sample t test and paired sample t test for subsequent statistical analysis.

    Based on the analysis of experimental data, we can observe that after the structured street dance intervention, the PHQ-15, SDS and SASdefen of the subjects showed a significant downward trend. From the perspective of physical feelings, major problems such as muscle tension, poor sleep quality, and physical discomfort with many unclear causes have been significantly improved. From the psychological and emotional aspects, when we conducted follow-up visits, most of the subjects responded that after completing the structured street dance intervention, they were more willing to open their hearts and express themselves, and their self-acceptance was significantly increased.。

    The results show that the appropriate street dance intervention is fully qualified as an auxiliary exercise rehabilitation method. By combining physical activity, rhythm feeling and body emotion expression, street dance can effectively improve the vicious circle of mutual aggravation of negative emotions and physical discomfort in adolescents. Based on the results of the study, we believe that a reasonably planned structured street dance intervention can be used as an auxiliary means to cooperate with clinical work to effectively alleviate adolescent emotional disorders and somatization symptoms. The street dance movement itself emphasizes self-expression and peer collaboration, and is in line with the preferences of teenagers. Street dance has great potential in the direction of adolescent mental health and assisted rehabilitation. We still need to expand the sample range to carry out randomized controlled trials, continue to test the effect of the intervention program to maintain the degree of disease to build a unified set of intervention implementation standards.
