Abstract

Background. The aim of the study was to analyse the relationship between lateral spinal curvatures and MLPX and MLPY among children aged 12 to 15 years. Material and methods. The sample consisted of 503 children chosen from among attending Promary School No. 13 and Junior Secondary School No. 4 in Starachowice. The spatial photogrammetric method, based on Moire’s topography, was used. Balance was examined on a stabilographic platform. The MLPX and the MLPY were used to describe balance findings. Results. Analysis of variance showed a significant effect of the testing options. In the test with eyest closed, MLPX increased in all three defect groups in the frontal plane. Closing eyes increases MLPX, which reflects an increased pressure of the left leg. Increased instability in this plane is usually effectively compensated for by the hip joint strategy. Conclusions. Although the analysis of variance did not show any essential effects, the value of MLPY with eyes closed was hightest in curvatures >10o. This group also showed the biggest difference in Romberg’s test.
