Today we know that one in four children in Ukraine has an incorrect posture and complex pathological processes are diagnosed in 7–8 children per thousand of the population concerned. The causes of disorders of a posture is a rational driving mode, an unbalanced diet and a low tone of major muscle groups of the trunk and limbs, especially during the periods of active growth of the musculoskeletal system. A proportion of the body of the child and correlation of processes of the development and growth is a complex dynamic system. The manifestation changes of a posture is underdeveloped muscles that hold the correct body position in space, asymmetry of the blades relative to the axis of the straight, shoulders, triangles waist, pelvis and scoliosis curves without torsion vertebrae. The above changes are progressing in two planes – sagittal and frontal. Violations of a posture in the sagittal plane include changes and simplify all physiological curves. Spinal deformity children in the sagittal plane is the most common disorders of the musculoskeletal system, their frequency of more than 15% of the population of children, including irreversible pathological changes occurred between 1,5–2,0% of child contingent. The result of a comprehensive medical examination revealed 45% of children with a posture. Examination of healthy children with brachial index and the index of vertical deviation of the spine, makes it possible to identify «at risk» possible future changes of their posture. To change the initial posture in the sagittal plane inclined 29,41% of children in the frontal plane – 16,34% of children. Calculation method with using brachial index and the index of vertical deflection spine informative as sensitivity brachial index is 83.66%, and brachial index and the index of vertical deflection spine – 70,59% on the reference method. Using indexing techniques can detect and warn in advance and carry out effective rehabilitation of children with physical posture. So index method to detect violations of posture in the sagittal and frontal planes is versatile and informative for all ages of children.
