Changes in body posture parameters: a four-year follow-up study

Body posture is an alignment of its segments relative to each other in a certain way and the relations between them. Abnormalities in the alignment of body segments or the cooperation of systems may cause postural defects. Scientific evidence showed that children of school age are more exposed to abnormalities in body posture so posture should be monitored because it is a key aspect of their body's physical health. This study aimed to evaluate changes in body posture parameters in the frontal plane in the same children at 5 and then 9 years of age. This four-year follow-up study included 67 children (29 girls and 38 boys) in preschool-age and school-age phases (the first examination at 5 years of age and the second examination at 9 years of age). Measurements of body weight and height were recorded. The computerized assessment of body posture was performed with the photogrammetric method (MORA 4 Generation). The normality of the distribution of variables was assessed with the Shapiro-Wilk test. Analysis of qualitative data was carried out using Pearson’s chi-squared test. The highest percentage of children were characterized by the deterioration in the position of the lower corners of the scapulae, taking into account the division into sex (respectively in girls 51.7 % and boys 50.0 %) and the analysis of the whole group (50.7 %). There were statistically significant differences in the position of the lower corners of scapulae (UL) between the first and second examinations in all examined children (p = 0.005). The difference in the height of the waist and in the position of the shoulders improved and deteriorated in a similar percentage in children (above 30-40 %). Generally, an improvement in body posture was observed, however, the occurred abnormalities of body posture indicate the need to continuously monitor the children's posture and implementation of preventive and corrective measures.

The aim of the study was to assess the differences in plantar pressure distribution and in posture during slow and very slow walking on the treadmill in flat and high-heeled shoes. Methods: The Pedar-X® (Novel, Munich, Germany) measuring insoles were used to measure the plantar pressure distribution and to assess temporal parameters during walking on the treadmill with the speed v1 = 0.97 ms–1 and v2 = 0.56 ms–1 in flat shoes (FS) and HH. For postural measurement, the SonoSens Monitor Analyzer (Gefremed, Chemnitz, Germany) was used. Thirty healthy females who only occasionally wear HH volunteered to participate in the study (age: 21.8 ± 2.09 years, weight: 55.7 ± 4.05 kg, height: 1.66 ± 0.03 m). For statistical analysis the ANOVA, and paired t-test were used. Results: Significant differences in walking in HH were detected in temporal and plantar pressure variables, compared to FS. The walking speed influenced the temporal variables, but not the measured dynamic parameters, in either shoes. In the sagittal plane, significant differences in all sections of the spine were identified for v1 and v2. While walking in HH, lordosis at lumbar spine decreased significantly as well as at cervical spine, and kyphosis increased in the thoracic spine. In HH statistically significant differences between the walking speeds were observed particularly in the thoracic spine. Conclusions: Walking in high heels caused a plantar pressure changes and curvature of the spine, and the slowing of walking speed did not prevent these changes.

Celem pracy była ocena postawy ciała w płaszczyźnie czołowej dzieci w wieku "przedszkolnym. Grupę badawczą stanowiło 95 dzieci w wieku 3 - 6 lat uczęszczających do Przedszkola nr 136 we Wrocławiu. Średnia wieku wynosiła 4,8 lat (odchylenie standardowe 0,75). Uczestników badania podzielono na trzy grupy wiekowe. Grupę 1 stanowiły dzieci 3-4-letnie, grupę 2 dzieci 5-letnie, a w grupie 3 znalazły się dzieci w wieku 6 lat. W badanej grupie przeprowadzono komputerową ocenę postawy ciała z wykorzystaniem mory projekcyjnej. Na podstawie przeprowadzonej analizy statystycznej stwierdzono, że asymetria tułowia w płaszczyźnie czołowej u dzieci występuje często, a jej wielkość jest bardzo zróżnicowana. Asymetrię stwierdzono najczęściej w ustawieniu miednicy oraz trójkątów talii. Największy odsetek znacznych asymetrii zaobserwowano w różnicy wysokości kątów dolnych łopatek.

The goal of the study was to assess the posture in the frontal plane in the group of pre-school children. The study group included 95 children, at the age from 3 to 6, attending kindergarten No. 136 in Wrocław. The mean age of examined children was 4.8 years (SD 0,75). The participants were divided into three groups, depending on the age. The group 1 included children at the age of 3-4, the 2. group children 5-years old and the group 3 consisted of children at the age of 6. The computer-aided assessment of posture was conducted based on the projection moire. On the basis of the statistical analysis, it was found that trunk asymmetry in the frontal plane occurs frequently in children, and its value is highly diversified. Most frequently, the asymmetry was found in the pelvis and waist triangles. The highest percentage of considerable asymmetry was observed in the region of inferior angles of the scapulae.
