The objective of the study was analysis of the relationship between body posture and balance reactions in girls and boys aged 12-15 years. The study covered 503 girls and boys aged 12-15 attending randomly selected Primary School, and Junior High School in Poland. Body posture was examined by means of spatial photogrammetry using the projection moire effect. Postural reations were tested on an R50300 Cosmogamma platform by Emildue. In the saggital plane, 297 (59.05%) correct postures and 206 (40.95%) postural defects were observed. In the frontal plane, there were only 3 (0.60%) correct postures, 238 (47.32%) scoliotic postures, 262 (52.09%) residual scoliosis, and 46 (9.15%) idiopathic scoliosis >10°. A significant relationship was observed between anterior-posterior speed with closed eyes and lateral curvature of the spine, both with defects in the saggital plane and without these defects (p=0.044). Lateral curvatures of the spine and defects in the saggital plane are accompanied by a clear increase in the anterior-posterior speed. A significant relationship was found between the mean loading point Y with open eyes and lateral curvature of the spine, both with postural defects and without these defects (p=0.043). This parameter was the highest among the defects in the saggital plane, without lateral curvature of the spine. A significant relationship was also observed between the mean sway X (p=0.009) and the mean sway Y in the test with eyes open (p=0.046), and defects in the saggital plane, both with lateral curvature of the spine and without these defects.
