“…Одним из наиболее перспективных здоровьесберегающих направлений организации образовательной деятельности является режим динамических поз [15][16][17][18]. Сущность технологии обучения в режиме динамических поз состоит в чередовании детьми положений сидя и стоя в середине каждого урока в течение всего учебного дня.…”

Background: Scientific substantiation of a health-preserving potential of innovative educational technologies, learning modes, and non-traditional types of student furniture is one of the most important tasks of school medicine. The mode of dynamic postures presupposing alternation of sitting and standing positions at each lesson during the school day has got potential health-preserving resources. Our objective was to assess foot conditions in primary school children in years 1–3 studying in the mode of dynamic postures. Materials and methods: The study was conducted in 2015-2018 involving 42 children aged 7–10 years attending a gymnasium in the town of Balashikha, Moscow Region. The condition of the longitudinal foot arch was assessed by plantography using the Bauerfeind plantograph, Germany. For the same children, the Sztriter index was calculated in the beginning of year 1 and in the end of year 3. Results: The normal longitudinal foot arch was observed in 36.9% and 42.9% of schoolchildren studying in dynamic postures in years 1 and 3, respectively. Flat feet were detected in every fifth child and its prevalence did not change in the course of learning. The most pronounced positive dynamics expressed by a 5.9-fold decrease in the prevalence rate was observed for the higher arch of the foot noted in 21.4% of first graders and only in 3.6% of third graders. Conclusions: Our findings show positive dynamics in foot conditions related to the process of learning in the mode of dynamic postures and may serve as the basis for a wider introduction of this mode into educational practice.

Introduction: Deterioration of health of children and adolescents during school years is of particular concern to domestic experts. Myopia and diseases of the musculoskeletal system traditionally rank high in the structure of pediatric diseases. Objective: To study the prevalence of school-related risk factors for postural disorders and spinal deformities in schoolchildren of different age groups. Materials and methods: The study was conducted in December 2022 involving 278 students aged 9–15 years. We evaluated the lesson timetable, functional parameters of school furniture, weights of schoolbags and supplies, and the compliance of indoor shoes with hygienic requirements. The data were then analyzed to obtain the mean, minimum and maximum values, the share of the trait, and the significance of differences was assessed using Fisher’s exact test. Results: We found violations in organization of the educational process, such as double lessons and the absence of in-class physical activity breaks, in all grades. Evaluation of classroom furniture showed that the proportion of table and chair mismatch with the height of students in elementary school was 32.09 % and 40.30 %, decreasing by the ninth grade to 13.16 % and 21.05 %, respectively. The mean weight of the schoolbag was above the permitted level in 97.14 % of elementary school girls and in 20.68 % of girls in grades 7–8 (φemp = 8.395; p ≤ 0.001); as for boys, the recommended schoolbag weight was exceeded in 93.75 % of third to fourth graders and 28 % of seventh to eighth graders (φemp = 6.46; р ≤ 0.001). Assessment of the compliance of indoor shoes with hygienic requirements revealed a significant (φemp = 1.85; p ≤ 0.05) excess in the number of elementary school boys (71.32 %) who prefer sneakers; more than a third of girls of all age groups have ballet flats or sneakers as their indoor footwear. Conclusion: The prevalence of school-related risk factors for posture disorders is higher in elementary school, which makes it possible to predict an increase in the number of students with dorsopathy in high school. To maintain health of students, a set of measures has been proposed to minimize the adverse impact of school-related risk factors.

Intriduction. Purpose of the study - is to evaluate the influence of ergonomic parameters of modern educational environment workplaces on the manifestation of musculoskeletal discomfort in adolescents. Materials and methods. The conformity of the size of the working places at school to the anthropometric parameters of adolescents was assessed, the goniometric parameters of the working postures were evaluated, presence of musculoskeletal discomfort was studied using an adapted version of the Nordic Questionnaire, and associated factors during the questionnaire. Results. There were revealed discrepancies between the size of the school educational furniture and the anthropometric data of adolescents, the presence of deviations from the recommended ranges for the goniometric indicators of the working postures of adolescents at school. There is a high prevalence of musculoskeletal discomfort among adolescents. The results of the influence of an irrational working posture on the manifestation of musculoskeletal discomfort among adolescents have been obtained. Limitations. The study included groups of 10-11 years and 15-16 years adolescents. The questionnaire method was used to assess the manifestations of musculoskeletal discomfort, with no study of musculoskeletal disorders in adolescents. The study was cross-sectional in nature. Conclusion. to prevent posture disorders and manifestations of musculoskeletal discomfort, it is important to teach adolescents ergonomic principles, the prevention of musculoskeletal disorders, and the preservation of a rational working posture in school activities.
