Abstract

The objective of the research was to show the significant influence of the angle, depth, height and length of lumbar lordosis on selected features of the spine and pelvis.

Material and methods: The research was carried out in a_group of 2,361 children aged 7 to 15, in 6 consecutive six-month editions. It made it possible to register 16,608 observations of 31 features describing body posture using the photogrammetric method.

Results: For multiple regression analysis with the selection of a_subset of the optimal set of variables, the following influencing features were selected: angle, depth, height and length of lumbar lordosis.

Conclusions.

1. The features of lumbar lordosis do not influence the angle of torsion and inclination of the pelvis, and the influence on the features of the thoracic spine is varied.

2. The features of lumbar lordosis influence the height, depth and angle of thoracic kyphosis.

3. The length of lumbar lordosis does not influence the length of thoracic kyphosis, and the angle of lumbar lordosis does not influence the length of lumbar lordosis.

Key words:

lumbar lordosis, spine, pelvis
