Upper thoracic curve mean Cobb angles changes, Lower thoracic curve mean Cobb angles changes, Lumbar curves mean Cobb angles changes, Thoracolumbar curves mean Cobb angles changes and Standard Deviations. Analysis of variance (ANOVA) between all groups for upper thoracic curve Cobb angles showed significance difference at 20th and 40th weeks (p = 0.018 and p = 0.001, respectively). Subgroup analysis showed that at 20th week there was significant difference between TMX and Control (p = 0.029), and TMX and RLX groups (p = 0.045) for upper thoracic curves. At 40th week, lower thoracic curve Cobb angles between all groups was significant (p = 0.011). Subgroup analysis revealed that there was significant difference between RLX and Control groups (p = 0.034) and between RLX and TMX groups (p = 0.015).
