Background: Scoliosis is a complex three-dimensional spinal deformity in frontal, sagittal, and horizontal planes, with a cobb’s angle greater than 10 degrees and vertebral rotation greater than 3 degrees. The purpose of the present study, was to investigate the effect of Schroth’s three-dimensional exercises (SE) and insole on male adolescents with idiopathic scoliosis. Methodology: In this quasi-experimental study, 30 adolescent boys with idiopathic scoliosis) mean age of 14.95 years, height of 166.6 cm and weight of 55.83 kg (participated and were randomly divided into three groups of SE, insole and control (n=10). Subjects in exercise group performed Schroth’s three-dimensional exercises protocol 3 sessions per week for 8 weeks. In the insole group (IG), participants were instructed to wear the customized ethylene vinyl acetate (EVA) insoles at least for 4 hours per day for 8 weeks. The control group did not receive any special treatment during this period. The Formetric 4D System (Diers International GmbH, Schlangenbad, Germany) is a surface topography system that was used to evaluate the cobb’s angle in this study. Paired t-test and one-way ANOVA were used to analyze the data (p≤0.05). Results: The paired t-test results between the pre and post measurement showed that the Cobb’s angle decreased after eight weeks in the two intervention groups (p≤ 0/05). Also ANOVA showed a significant difference in post-test (F=6.949, P=0.004), and post-hock test showed that there was more significant improvement of the Cobb’s angle in the SE group than in the IG. Conclusion: According to the results, SE and insole are useful ways to improve the cobb’s angle in adolescents with idiopathic scoliosis deformity. Due to the effectiveness of both interventions, it is recommended to use both SE and insole in the treatment plan of patients with idiopathic scoliosis.
