Background: The promising results of idiopathic scoliosis for children and adolescent idiopathic scoliosis found in low-quality in review of literature in Iran. Aim : The purpose of this study was to investigate the effect of various types of exercises to improve idiopathic scoliosis in terms of reducing Cobb angle and angle of trunk rotation (ATR) in different ages of children and adolescents. Materials and Methods: Searches were conducted in databases including Cochrane, PubMed, Scopus and Google Scholar during 2005-2021. Inclusion criteria were papers using only corrective exercises (CE) or CEs with braces as an intervention. The PEDro scale was used for evaluating the quality of papers. Results: Thirteen papers were licensed for review. The papers (PEDro: 4-9) showed the positive effect of the CEs in reducing Cobb angle (eleven papers) and ATR (eight papers) greater than 5° and 3°, respectively. Moreover, two papers (PEDro: 4-7) showed that the physiotherapy scoliosis specific exercises (PSSE) were more effective than the general exercises (GE), while no paper was found to compare one PSSE to another. Two papers (PEDro: 6-9) indicated the greater effectiveness of CEs in childhood than adolescence. Conclusion: The relative evidence suggested the effect of CEs on improving idiopathic scoliosis, especially in children. However, it seems that the use of SEAS and Schroth methods, depending on the individual nature, can be more effective. High-quality papers are necessary to achieve more accurate results in the future.

The present study aimed to investigate the relationship between perfectionism and narcissism with psychosocial adaptation in elite and non-elite athletes. A total of 200 elite and non-elite athletes (20-30 years old) who participated in the tournament of 2020 in Tabriz were randomly selected and completed the questionnaire of Sport Perfectionism - 2nd Dun et al. (2009 and 2010), Ruskin and Terry narcissism and Bell Social Adaptation Inventory. To analyze the results, Pearson correlation coefficient and simultaneous regression analysis were used. The results showed that in elite athletes group, there was a positive correlation between positive perfectionism (organizational and personal criteria) and psychological social adjustment, and between negative perfectionism (doubts about actions, perceived pressure of parents and perceived pressure of instructor) and narcissism with negative psychological social adjustment and both positive and negative perfectionism and narcissism variables could significantly predict social adjustment in elite athletes (P <0.05). In non-elite group between positive components of perfectionism, only the organizational component has a negative correlation with psychological social adjustment and the correlation between negative and narcissistic perfectionism components with positive social adjustment is positive. Among the components of perfectionism, the only negative components (too much importance by mistake, parental perception and perceived stress of the mentor) and the narcissistic variable have been able positively to predict psychosocial compatibility (P <0.05). Psychological social adjustment in athletes is one of the key variables in the professional and personal life of athletes, which is influenced by features such as perfectionism and narcissism.
