Introduction: Elongation exercises are designed to reduce existing pathological or increased physiological curvatures of the spine. The aim of the study was to evaluate the changes occurring in the parameters describing the anterior-posterior spinal curvatures during the performance of symmetric elongation exercises.

BACKGROUND: Nowadays, children spend increasingly more time in a seated position, both at school during class and at home in front of a computer or television. OBJECTIVE: The aim of this study was to compare selected parameters describing body posture and scoliosis among children in sitting and standing positions. METHODS: It was an observational, cross-sectional study involving 91 primary school children aged 11-13 years. The children's backs were photographed in standing and sitting positions. The values of selected parameters were calculated using photogrammetric examination based on the Moire projection phenomenon. RESULTS: The results show significant statistical differences for the parameters defining the anteroposterior curves of the spine. The sitting position resulted in a decreased angle of inclination of the thoracolumbar spine, reduced depths of thoracic kyphosis and lumbar lordosis, and pelvic asymmetry. CONCLUSIONS: Maintaining a sitting position for a long time results in advanced asymmetries of the trunk and scoliosis, and causes a decrease in lumbar lordosis and kyphosis of a child's entire spine. Therefore, we advocate the introduction of posture education programs for schoolchildren. [ABSTRACT FROM AUTHOR]

BACKGROUND: Carrying a backpack is common among schoolchildren. The effect of backpack load on spine pain and posture defects in children is often raised in the literature. According to scientific research, the maximum backpack load that is safe for children must not exceed 10-15% of their body mass. There is a lack of scientific reports related to the effect of frequently wearing a backpack on one shoulder among children and young adults and its influence on the shape of the anterior-posterior curvatures of spine. OBJECTIVES: The aim of this study is to evaluate body posture parameters in the sagittal plane for an asymmetrical backpack load equal to 10% of a child's body mass. METHODS: The study was conducted using 162 primary schoolchildren aged 11-13 years. Each participant underwent three tests that examined postural parameters, including habitual posture, with the backpack on the participant's right and left shoulder. Posture was measured with the CQ Elektronik; which uses photogrammetry to make anthropometric calculations based on an image of the examined surface. RESULTS: The asymmetrical backpack load resulted in a significant reduction of thoracic kyphosis (GKP: p - 0.040). The angle of thoracic kyphosis increased between the measurements. The difference (GAMMA = 0.054) revealed that the results were approaching significance. CONCLUSIONS: Considering the gravity of the problem, children should be educated on ergonomics by teachers, physiotherapist or nurses, including instructions on carrying a backpack and the effects of disregarding the basic rules on body posture, as part of their school curriculum. The acceptable backpack load, which is now believed to be 10% of the child's body mass, should be carefully considered by scientists. Our own results show that even a load of 10% of the body mass may induce negative changes in spinal posture. [ABSTRACT FROM AUTHOR]

The article discusses research examining the effects of changes in the body posture parameters defining asymmetries of the trunk and lateral flexion of the spine in children while carrying a backpack. Topics discussed include impact of the backache on the posture of schoolchildren and its contribute to spinal pain; suggests for teaching basic ergonomic principles on how to carry loads to students; and changes to the management pattern of carrying textbooks.

Purpose: Correct foot structure is important due to locomotion and postural stability. The aim of this study was to determine the relationships between morphological foot structure and balance indices in a quiet standing position in women over 65 years of age. Methods: The study included 116 women aged 65-90 years. The mean age was 70.6 ± 8.4 years and BMI 29.1 ± 3.4 m/kg². The measured indices included postural control while standing on both feet and photogrammetric foot evaluation. An analysis was performed of the selected foot and balance indices. Results: There were no significant differences observed in the feet structure. Certain correlations between some foot indices and the indices of postural control were noted. The increased differences in the width indices between the right and the left foot lead to balance deterioration. Larger angles of valgity and varus deformity of toes and indices describing the longitudinal arch and transverse front arch of the foot have the greatest impact on the deterioration of balance in the medio-lateral axis. Conclusions: The differences between the indices and morphological indices for the right and the left foot are not significant, which indicates the proportionate formation of feet in the individual life. The increased differences in the width indices between the right and the left foot lead to balance deterioration. Larger angles of valgity and varus deformity of toes and indices describing the longitudinal arch and transverse front arch of the foot have the greatest impact on the deterioration of balance in the medio-lateral axis.

Introduction: Pain disorders of the spine are the most common causes of appointments with physiotherapists. It has been estimated that nine out of ten adults at least once in their lifetime experience spine pains and five out of ten working people have this kind of ailments a minimum once a year., Objective: The evaluation of the occurrence of spine pains in people who are professionally active with regards to obeying the rules of work ergonomics., Material and Methods: The research group has been composed of 100 people professionally active from south-eastern Poland. Their ages have been from 20 to 50 years (average age has been 35 years). In the research the authors' own survey and VAS scale have been used on which the surveyed person has marked the intensity of pain experience in the area of the spine., Results: Greater pain in the spine has been experienced by people who have never obeyed the rules of, among others, manual lifting and/or carrying the maximum load, lifting and carrying heavy objects, in their work. The lowest degree of pain has been experienced by those who obeyed the above-mentioned rules., Conclusions: Assuming the incorrect body posture during the everyday activities and disobeying the rules of ergonomics resulting from lack of knowledge are crucial factors in the occurrence of spine pains. People who disobey rules of ergonomics experienced spine pain to a higher degree.
