PURPOSE: The purpose of this study was to investigate the effects of 3 dimensional exercises and Klapp’s exercise on parameters of scoliosis in subjects with non-structure scoliosis. METHOD: This study was performed on 24 subjects. Twenty-four subjects were divided into two groups; 3 dimensional exercise(n=12), Klapp’s exercise(n=12). Both of the group performed the exercise 3 times a week for 5 weeks. The data was analyzed by the Paired t-test for comparing before and after changes of factors in each group and the Independent t-test for comparing the between groups. RESULT: The result are as follows. There was statistically significant difference of before and after arthopometric parameters, trunk flexion, Cobb``s angle in 3 dimensional exercise(p<0.05). There was statistically significant difference of before and after acromion high, trunk extension, Cobb``s angle in Klapp’s exercise(p<0.05). There was no statistically significant difference of between the two group in arthropometric parameters, ROM, Cobb``s angle(p>0.05). CONCLUSION: As a result of this study, we found that the 3 dimensional exercise may be effective more than Klapp’s exercise.
