Own Typology of Body Posture Based on Research Using the Diers Formetric III 4D System.

Background/Objectives: Body posture is developmentally variable and individually diversified. As a chain of numerous unconditioned and conditioned reflexes, it is, in its essence, a psychomotor habit. The aim of the study was to create an original typology of body posture based on measurements using the Diers Formetric III 4D system. Methods: The research included 303 children aged 10-12. Results: Taking the ranges of standards for the angle of thoracic kyphosis (42-55°) and lumbar lordosis (33-47°) into account, it was shown that there are nine types of body posture. These are as follows: reduced kyphosis, reduced lordosis (K < 42°; L < 33°); reduced kyphosis, normal lordosis (K < 42°; 33° ≤ L ≤ 47°); reduced kyphosis, increased lordosis (K < 42°; L > 47°); normal kyphosis, reduced lordosis (42° ≤ K ≤ 55°; L < 33°); normal kyphosis, normal lordosis (42° ≤ K ≤ 55; 33° ≤ L ≤ 47°); normal kyphosis, increased lordosis (42° ≤ K ≤ 55°; L > 47°); increased kyphosis, reduced lordosis (K > 55°, L < 33°); increased kyphosis, normal lordosis (K > 55°; 33° ≤ L ≤ 47°); and increased kyphosis, increased lordosis (K > 55°; L > 47°). Conclusions: In the final evaluation of the Diers Formetric III 4D examination, the traditional division into round, concave, round-concave, and flat backs should be supplemented and expanded to include the nine posture types mentioned above. This will enable a more precise selection of corrective exercises, which will significantly improve their quality and effectiveness.
