The variety of the scoliosis deformities is large. They can differ in type and severity. Our interest is the effectiveness of teaching in corrective exercises. Our aim is to follow the dynamics of the posterior (POTSI) and anterior trunk symmetry index (ATSI) in relation to the type of scoliosis deformity according to Rigo classification. For a period of 2 years and 8 months (April 2014 - November 2016) we accessed 128 children with adolescent idiopathic scoliosis with different severity--low 7.8%, low to moderate 20.3%, moderate 39.1%, moderate to severe 17.2%, severe 11.7% and very severe 3.9%. They were distributed in 4 groups according to Manuel Rigo: 3C (single thoracic or thoracolumbar) 29.6%, 4C (double major) 25%, N3N4 (scoliosis with good balance) 31.3% and G 1-2 (single lumbar) 14.1%. We made photos from anterior and posterior for calculating POTSI and ATSI in the beginning of therapy and on the 5th day after exercises. All patients we taught to make exercises for correction according to Schroth method after the initial evaluation. Teaching the patients included 5 consecutive days of 120 min in small groups of 2 children. The highest initial POTSI asymmetry was found in group 3C 42.14 [+ or -] 20, with lowest POTSI asymmetry in group N3N4 with 23.22 [+ or -] 11.38. With ATSI the highest initial asymmetry was in 3C 29.09 [+ or -] 12.73 and 4C 30.11 [+ or -] 13.49, with lowest asymmetry in G 1-2 20.41 [+ or -] 12.86. We have statistically significant improvement in all patients as for POTSI from initial 31.27 [+ or -] 17.1 to the end value of 23.08 [+ or -] 14.38 (0.634, p Improvement in the trunk symmetry does not depend on the severity and type of scoliosis, but only on the initial values. With PSSE we have statistically significant improvement in the symmetry indices (POTSI and ATSI) only for 5 days intensive training. Single thoracic and single thoracolumbar scoliosis leads to the most pronounced asymmetry in comparison to the scoliosis with good trunk balance.
