Streszczenie

Wstęp. Periodycznie, na przełomie sierpnia i września, podnosi się problem przeciążania dzieci zbyt ciężkimi plecakami szkolnymi i sugeruje wpływ tego obciążenia na inicjację różnych dysfunkcji, nie tylko w obrębie kręgosłupa.
Materiał, metoda. Badania postawy ciała przeprowadzono w grupie 65 uczniów w wieku 7 lat metodą mory projekcyjnej w 8 pozycjach. Pierwsza – postawa habitualna, druga – po 10-minutowym asymetrycznym obciążeniu na lewym lub prawym barku, trzecia – po jednej minucie od zdjęcia obciążenia, czwarta – po dwóch minutach od zdjęcia obciążenia. Dokonano pomiaru sprawności fizycznej testem Sekity.
Wyniki. Analizowano istotność różnic między 1 a 2, 1 a 3, 1 a 4, 2 a 3, 3 a 4 pomiarem dla określenia wpływu obciążenia oraz korelacji różnic ze sprawnością fizyczną. Zbadano także, który sposób transportu mniej zaburza postawę ciała.
Wnioski.
1. Transport 4-kilogramowej masy przyborów szkolnych na lewym lub prawym barku tak samo istotnie i negatywnie zaburza biomechaniczną statykę ciała 7-letniego dziecka, co może w dłuższej perspektywie czasu wywołać błędy, a w konsekwencji wady postawy ciała. W związku z tym nie należy zalecać tego sposobu transportu przyborów szkolnych uczniom klas pierwszych.
2. Sprawność fizyczna ma większe znaczenie w zaburzeniach biomechanicznej statyki postawy ciała w płaszczyźnie czołowej niż w strzałkowej i poprzecznej oraz wśród chłopców niż dziewcząt. Wytrzymałość i siła wykazuje najczęstsze związki ze zmianami wielkości cech postawy ciała, przy czym w płaszczyźnie strzałkowej i poprzecznej największe znaczenie ma szybkość i siła, a w czołowej wytrzymałość i siła.
3. Restytucja wielkości żadnej z analizowanych cech postawy ciała nie była pełna po 1. i 2. minucie od zaprzestania transportu na lewym i prawym barku, co świadczy o niskiej sprawności ogólnej i niedojrzałych procesach korekcyjno-kompensacyjnych.

DOI: https://doi.org/10.56984/8ZG07BFF3

Abstract

Introduction. The analysis of the pupil’s environment is a set of stressors in the field of human ecology consisting not only of the genetic factor but also of the epigenetic one. Material and methods. The study of body posture was carried out in a group of 65 pupils at the age of 7, using the mora projection method in the following eight positions: (four positions for the right-hand thrust and four for the left-hand thrust): 1- habitual posture, 2 – posture after pulling a container with school supplies with one hand for 10 minutes, 3 – one minute after removing the load, 4 – two minutes after removing the load. The measurement of physical fitness was performed using the Sekita test. Results. The significance of differences between measurement 1, 2, 3, and 4 was analysed to determine the restitution of the size of traits after loading and their correlation with physical fitness to examine the relationship with the studied differences. Conclusions. (1) After removing the load, statistically significant restitution occurred after the first and second minute. Restitution was incomplete. (2) In right-hand carriage by boys, endurance significantly correlated with restitution, and among girls it was additionally speed and agility. As regards girls, physical fitness revealed more frequent relationships with restitution. (3) In left-hand carriage by boys, after the first minute, restitution correlated with endurance, power, agility and overall physical fitness, and after two minutes, additionally with strength, while among girls with strength, power, and endurance. After two minutes, restitution correlated with speed and agility in addition to the abovementioned postural features. As far as girls are concerned, physical fitness more often correlated with restitution. (4) Due to incomplete restitution after one and two minutes, asymmetrical carriage is not recommended to children aged 7 years. Physical fitness demonstrated by children does not lead to full restitution of the examined postural features, which suggests its low level and immature correctional and compensational processes.

Abstract
The objective of the research was to show the significant influence of the angle, depth, height and length of lumbar lordosis on selected features of the spine and pelvis.
Material and methods: The research was carried out in a_group of 2,361 children aged 7 to 15, in 6 consecutive six-month editions. It made it possible to register 16,608 observations of 31 features describing body posture using the photogrammetric method.
Results: For multiple regression analysis with the selection of a_subset of the optimal set of variables, the following influencing features were selected: angle, depth, height and length of lumbar lordosis.
Conclusions.
1. The features of lumbar lordosis do not influence the angle of torsion and inclination of the pelvis, and the influence on the features of the thoracic spine is varied.
2. The features of lumbar lordosis influence the height, depth and angle of thoracic kyphosis.
3. The length of lumbar lordosis does not influence the length of thoracic kyphosis, and the angle of lumbar lordosis does not influence the length of lumbar lordosis.

Abstract
Material, methods. The study covered 65 pupils aged 7, using the mora projection method in four positions: 1 – habitual posture 2 – posture after pulling a container with supplies with right hand for 10 minutes, then with left hand, 3 – one minute after removing the load, 4 – two minutes after removing the load. Physical fitness was measured using the Sekita test. Significance of differences between measurement 2 and 3, and 3 and 4 was analysed to determine restitution of the size of traits after loading and correlation with physical fitness to examine the relationship with differences. Conclusions. (1) Having excluded the load of transported mass, statistically significant restitution occurred after one and two minutes. Restitution was incomplete and independent of gender. (2) In right-hand transport by boys, after one minute, speed and strength significantly correlated with restitution, and after two minutes, endurance, speed, strength and agility correlated with it. Among girls, after one minute, restitution correlated with strength, and after two minutes with endurance and strength. (3) In left-hand transport by boys, after one minute, restitution correlated with strength, power agility and overall fitness, and after two minutes, with endurance, speed, agility and overall physical fitness. Among girls, after one minute, restitution correlated with endurance, speed, strength and agility, after two minutes, with endurance, speed, agility and overall fitness. (4) Due to incomplete restitution of the size of posture, asymmetrical transport is not recommended to 7-year-old children. Physical fitness in children does not cause complete restitution of examined postural.

Mirosław Mrozkowiak – Standardization of the diagnosis of body posture using photogrammetric ethods MORA 4G HD. Fizjoterapia Polska 2021; 21(1); 26-40

Abstract
Introduction. Each test or diagnostic method should meet basic principles consisting of standardization, reliability, accuracy, and normalization. Study aim. An attempt to describe the standardization of body posture diagnostics using the photogrammetric method in a 7-year-old child. Material and methods. For nine consecutive days, we assessed body posture in a group of 52 children aged 7 years by means of the photogrammetric method. The girls’ average body mass was 24.46 kg and body height was 123.87 cm, and, among boys, these values were respectively: 24.56 kg and 123 cm. All children represented the slender body type. Findings. The conducted statistical analysis showed no significant differences between subsequent tests and within each feature describing body posture in all children involved in the study. Only in individual, the feature KLB: the shoulder line angle, where the right shoulder is higher, revealed a significant difference. Conclusions. Insignificant differences observed in subsequent measurements of torso features prove the accuracy and high standard of the instituted examination procedure and the significant reliability of test results obtained. There was a significant difference in the KLB parameter: the shoulder line angle is due to the cohort size rather than to the most limited inaccuracies. This significant difference may also be a consequence of the great lability of the child’s body posture and the trait itself.

Abstract
Introduction. The analysis of a student’s environment involves a set of stressors in the field of human ecology, including not only genetic but also epigenetic factors.
Material, method. Body posture examinations were carried out in a group of 65 students aged 7, using the moiré projection method in eight positions: 1 – habitual posture, 2 – posture after 10 minutes of pulling a container with school supplies with one hand, 3 – one minute after removing the load, 4 – two minutes after removing the load. Physical fitness was measured using the Sekita test, supplemented with an endurance test. The significance of differences between measurements 1 and 2 was analysed to determine the impact of load and its correlation with physical fitness, to study its impact on the value of differences in body posture features. Conclusions. 1. Transport of school supplies by pulling a container with the left or right hand causes significant changes in the values of selected body posture features of girls and boys. It should be assumed that these changes will be even greater the heavier the weight of the container, the longer the transport time and the greater the intensity of physical effort. Therefore, this method of transporting school supplies by first-grade students should not be recommended. 2. The level of general physical fitness has a diversified impact on the scope of changes in body posture features as a result of the adopted method of transport of school supplies. Among boys, the impact is significant, and among girls only when pulling with the right hand. Taking into account individual abilities, among boys, the value of posture features is affected by speed, power, endurance and agility, and among girls, additionally by strength.

M. Mrozkowiak, A. Kaiser – The evaluation of the imapct of flexion and extension angles and lateral torso flexion on the selected spine and pelvis parametres. Fizjoterapia Polska 2020; 20(1); 24-34

Abstract
The aim of the research was to assess the impact of flexion and extension angles and lateral torso flexion on the selected spine and pelvis parameters among the population of children aged between 7 and 15 years.
Material and methods. The research was conducted in randomly selected kindergartens and schools in the Warmia and Masuria region and the Pomerania region during six semi-annual editions. The study population consisted of 2,361 children. This allowed to record 16,608 observations of 31 parameters describing body posture using the photogrammetric method.
Results. The analysis of multiple regression with selection of the subset of the optimal set of variables included four parameters affecting the following: flexion angle and extension angle in the sagittal plane, angle of flexion to the left and to the right in the frontal plane. The set of variables included the parameters of the pelvis-spine complex.
Conclusions.
1. Spinal parameters are significantly and positively affected by the angle of torso extension in the sagittal plane and the angle of flexion to the left in the frontal plane and negatively influenced by the flexion angle in the sagittal plane.
2. The values of torso extension and flexion angles in the sagittal plane and torso flexion to the left and right in the frontal plane have a significant and positive impact on the total length of the spine (C7-S1) and the percentage of growth (DCK%), the Delta angle and the height of lumbar lordosis. The inclination angle of the lumbosacral spine, the total spinal length and the percentage of body height and the height of lumbar lordosis account for the parameters that are most dependent on the angles describing vertical orientation of the axial organ.
3. The significant negative impact on the spine parameters is remarkably lower. The most negatively dependent parameters include: lumbosacral inclination angle, the length and angle of thoracic kyphosis, and lumbar lordosis angle.
4. Hardly any influence of the analysed angles on pelvis parameters demonstrated herein requires further studies on the impact of foot parameters on the parameters of pelvis and spine.
5. The significant correlations of flexion and extension angles in the sagittal plane as well as the flexion angle in the frontal plane should be taken into consideration in the process of correcting body posture defects and errors.
