Influence of body posture on foot load distribution in young school-age children

Young school-age children are particularly prone to postural defects because they are in a period of development of the spine that is exposed to a number of factors impairing its normal growth. A change in the shape of the spinal column causes a shift in the centre of gravity. Therefore, this study attempted to assess the influence of body posture on distribution of the load transferred by the lower limbs. Methods: For each of the examined children, this study determined the parameters describing the body posture with the use of the photogrammetric method and the parameters describing plantar force distribution. The statistical analyses were performed using the U Mann– Whitney test and the student’s t-test. The correlations between the parameters of the body posture and the parameters describing the foot load distribution were analysed using the Pearson correlation coefficient. These analyses were performed at a statistically significant level of p < 0.05. Results: The tests conducted showed an occurrence of postural defects in about 42% of the subjects and excessively uneven loading of the lower limbs in about 65% of the children. Conclusions: The authors obtained a medium intensity correlation between the analysed parameters for the groups of boys and girls.

The paper presents the use of a diagnostics device Posturometer-S applied to examine body posture in hearing impaired children. 46 subjects from the Primary School for Hard-of-Hearing Children in Wrocław were examined. The research was conducted through the use of a Posturometer-S, which is an electronic, non-invasive measuring device attached to a computer. It enables not only the imaging and evaluation of frontal and sagittal curves of the spine, but also spinal mobility. Previous research has indicated that incorrect body posture was more often observed in hearing impaired children than in healthy ones. Hence, constant control over body posture in children with hearing loss seems vital. Correct body posture has a great influence on functioning of the entire body. The results obtained by using the Posturometer-S and anthropological measurements helped to determine the types of body posture and postural defects in the examined subjects. The apparatus used in research enabled to determine the occurrence of kyphotic, lordotic and balanced body postures, the results as follows: incorrect kyphotic postures - 10,9% of the subjects, incorrect lordotic postures - 6,4% and incorrect balanced postures - 10,9% of the examined subjects. Correct body postures were observed in 67,4% of the examined children. The most frequent body posture abnormalities were: thoracic scoliosis (19,6%) and shoulder asymmetry (26,1%). Due to the screening tests, some children were referred for further diagnostic evaluation and physiotherapy.
