Background: The aim of the study was to analyse the correlations between body posture parameters and postural stability in boys aged 10-12 years.
Material/Methods: The study involved a group of 159 boys aged 10-12 years from the Świętokrzyskie Voivodeship. Body posture was evaluated using the Diers formetric III 4D optoelectronic method, which allows photogrammetric registration of the back surface using the raster stereography process. Postural stability of the examined boys was evaluated using the Biodex Balance System balance platform.
Results: Spearman's rank correlation showed a directly proportional relationship be-tween selected postural stability parameters and the inflection point ILS (mm) as well as surface rotation (rms) (°). However, on inversely proportional relationships were found be-tween length of the trunk VP-DM (mm), length of the trunk VP-SP (mm) and the pelvic in-clination (symmetry line) (°).
Conclusions: The results showed that the poorer the postural stability of the subjects, the worse the quality of body posture.
