“…Coefficients of variation of relative indicators of the sum of transverse and sagittal sizes, the sum of all sizes, cross-sectional areas and volumes of intervertebral disks IVD L1-L2 , IVD L2-L3 , IVD L3-difference between the mean values in the groups for IVDL1-L2 6,159±0,921 mm, 7,182±0,932 mm for young men and men, the difference between the mean values was 1,023 mm. This indicator has significant variability due to the variability (individuality) of lumbar lordosis, which largely depends on conscious posture control [31] and has a fairly wide range of norm (20°-45°) [19].…”

An important element of evidence-based medicine is to take into account the individual variability of the indicators of the norm of intervertebral discs, which is undoubtedly the basis for early preclinical detection of their pathology. Mathematical modeling and comprehensive assessment of the parameters of the intervertebral discs can not only predict and determine the early manifestations of pathological changes, but also help to correct them in advance. The aim of the study was to calculate and evaluate the variability of absolute, calculated and relative metric parameters of intervertebral discs in the norm with the subsequent possibility of modeling standards based on individual linear dimensions of intervertebral discs of the lumbar spine and general anthropometric characteristics (body length and weight) in young men and men of the first period of adulthood (17-28 years), both in separate age groups and in the combined group. The series of MRI scans obtained on a Phillips Achieva 1.5T scanner measured the anterior, middle and posterior vertical dimensions, maximum sagittal and frontal dimensions of the intervertebral discs L1-L2, L2-L3, L3-L4, L4-L5 segments of the spine (IVDL1-L2, IVDL2-L3, IVDL3-L4, IVDL4- L5). We calculated the average height of the intervertebral discs, cross-sectional area and volume of intervertebral discs, as well as relative indicators - the ratio of the sum of sagittal and transverse dimensions, the sum of three dimensions, cross-sectional area and volume of intervertebral discs to the average intervertebral disc height. Statistical analysis of the obtained morphometric parameters was performed in the license package “STATISTICA 6.1”. The distribution of variation series indicators, their average values and standard errors, coefficients of variation and asymmetry were evaluated. It was determined that the sums of the transverse and sagittal sizes and the sums of the three sizes increase proportionally in the caudal direction, have a distribution of indicators as close as possible to normal, and their coefficients of variation are many times smaller than for cross-sectional areas and volumes. Indicators of the ratio of the sum of the sagittal and transverse size and the sum of the three sizes to the average height of the intervertebral discs have a variability of less than 10% and correspond to the characteristics of the general population. Body weight and length have significantly higher correlation coefficients with the sums of sagittal and transverse dimensions, the sums of three dimensions and cross-sectional areas than with the partial dimensions of the intervertebral discs.

Annotation. Individual variability of intervertebral discs is one of the factors that makes it difficult to recognize the early signs of their pathological changes before the onset of clinical manifestations. In the development of evidence-based medicine, it is important to use clear criteria for distinguishing between norm and pathology, taking into account individual variability. The “mathematical modeling” and a comprehensive approach to quantitative and qualitative assessment of intervertebral discs will help in the early detection of abnormalities, in the individualization of norm, as well as in modeling the parameters of the artificial intervertebral disc for reconstructive interventions. The analysis by methods of descriptive statistics and the correlation analysis for the purpose of further mathematical processing, selection of optimal parameters for mathematical modeling is carried out. Anthropometric characteristics (body length and body weight, mass-growth factor and mass-growth index) were determined in young women and women of the first period of adulthood (16-26 years), as in separate age groups and in the combined group. MRI of the lumbar spine was performed, followed by morphometry. Statistical analysis was performed in the license program “STATISTICA 6.1”. The mean values of the variation series, standard deviations, coefficients of variation and asymmetry, paired t-test, d-test of Kolmogorov-Smirnov type, Levene index were evaluated. It was determined that the sums of the transverse and sagittal dimensions and the sums of the three dimensions increase proportionally in the caudal direction, have a distribution of indicators as close as possible to normal, and their coefficients of variation are many times smaller than for cross-sectional areas and volumes. Indicators of the ratio of the sum of sagittal and transverse size and the sum of three sizes to the average height of the intervertebral discs have a variability of less than 10% and correspond to the characteristics of the general population. Body weight and body length have significantly higher correlation coefficients with the sums of sagittal and transverse dimensions, with the sums of three dimensions, and cross-sectional areas in comparison with the partial dimensions of the intervertebral discs.

“…Spinal postural competence can be defined as the equilibrium between the external forces acting on the spine and the muscular response of the trunk, which is sensory regulated to maintain a stable upright posture, both static and dynamic [11,12]. Therefore, the relationship between the foot to provide sensory information and the spine is critical for optimal posture and efficient balance control, both in adults and children [13].…”

Balance and posture are two topics that have been extensively studied, although with some conflicting findings. Therefore, the aim of this work is to analyze the relationship between the postural angles of the spine in the sagittal plane and the stable static balance. A cross-sectional study was conducted with children and adolescents from schools in northern Portugal in 2019. An online questionnaire was used to characterize the sample and analyze back pain. Spinal postural angle assessment (pelvic, lumbar, and thoracic) was performed using the Spinal Mouse®, while stabilometry assessment was performed using Namrol® Podoprint®. Statistical significance was set as α = 0.05. The results showed that girls have better balance variables. There is a weak correlation between the anthropometric variables with stabilometry variables and the postural angles. This correlation is mostly negative, except for the thoracic spine with anthropometric variables and the lumbar spine with BMI. The results showed that postural angles of the spine are poor predictors of the stabilometric variables. Concerning back pain, increasing the postural angle of the thoracic spine increases the odds ratio of manifestation of back pain by 3%.
