Characteristics of the correlations between body posture and postural stability in boys aged 10-12 years

Abstract

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 and 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.

The importance of extrinsic and intrinsic compensatory mechanisms to body posture of competitive athletes a systematic review and meta-analysis

“…The conducted meta-analysis corresponds with the uncertainty of the cited studies 6 , 7 , 20 and indicates the complexity of the phenomenon of body posture variability that seems to depend both on the kind of sport and training experience. At the same time, there is the need to indicate the importance of neurophysiological mechanisms to postural control in athletes, which were found to impact significantly on intrinsic postural regulation 33 . Furthermore, the findings of our meta-analysis directly indicate the sports in which athletes are characterized by greater values of thoracic kyphosis and/or lumbar lordosis angles (extrinsic adaptation mechanism).…”

Associations of Masticatory Muscles Asymmetry and Oral Health with Postural Control and Leg Injuries of Elite Junior Soccer Players

“…As the MNT has also a neuronal connection to the vestibular nuclei, the information from the masticatory muscles may affect the vestibular nuclei which play an essential role in maintaining postural control (Bieniek et al, 2019;Cuccia and Caradonna, 2009;Dolański et al, 2018;Gangloff and Perrin, 2002;Karimizadeh et al, 2020).…”

“…Another connection between the masticatory muscles and muscles activities responsible for postural control, is based on the anatomical connections between afferent neurons associated with masticatory muscles and the mesencephalic nucleus of the trigeminus (MNT). As the MNT has also a neuronal connection to the vestibular nuclei, the information from the masticatory muscles may affect the vestibular nuclei which play an essential role in maintaining postural control ( Bieniek et al, 2019 ; Cuccia and Caradonna, 2009 ; Dolański et al, 2018 ; Gangloff and Perrin, 2002 ; Karimizadeh et al, 2020 ).…”
