Background: Scoliosis is a condition that involves a lateral curvature and rotation of the spine that could cause noticeable posture deformities. There were several trials to assess the posture deformities that may associated with scoliosis. The purpose: to investigate the correlation between Cobb's angle and three dimensional changes of the head, rib cage and pelvis in adolescent idiopathic scoliotic patients .Subjects: Thirty patients, their age ranged from (11-15 years) with a mean (12.63±1.326) years participated in this study. Method: Rotation around x,y,z axes, translation around x,z axes were measured by postureprint soft ware for head, rib cage, and pelvis regions and full spine radiograph were taken for every patients. Results: There was significant correlation between Cobb's angle and 3D head changes (P ≤ 0.05) except changes around translation z axis (p=0.979). There was significant correlation between Cobb's angle and 3D rib cage changes (P ≤ 0.05) except changes around rotation y axis (p=0.267). There was significant correlation between Cobb's angle and 3D pelvis changes (P ≤ 0.05) except changes around rotation y and z axes (p=0.668, 0.382). Conclusion: There is a correlation between Cobb's angle and 3D posture changes of head, rib cage, and pelvis.
Posture Alignment of Adolescent Idiopathic Scoliosis: Photogrammetry in Scoliosis School Screening
Journal of Manipulative and Physiological Therapeutics, 2017
Objective: The objective of this study was to describe the posture patterns of adolescents diagnosed with adolescent idiopathic scoliosis (AIS) in a scoliosis school screening (SSS). Methods: Two-dimensional photogrammetry was used to assess the posture of 37 adolescents diagnosed with scoliosis (scoliosis group, SG) (Cobb angle ≥10°) and 76 adolescents with a false positive diagnosis (false positive group, FPG) (Cobb angle b10°, angle of trunk rotation ≥7°). In total, 2562 10-to 14-year-old adolescents were enrolled in the SSS, which was performed in public schools in the cities of Amparo, Pedreira, and Mogi Mirim in the state of São Paulo, Brazil. Their posture was analyzed using Postural Analysis Software. Continuous variables were tested using Student t test, and categorical variables were tested using a χ2 test. The SG, FPG, simple curve group, and double curve group were all compared. Bivariate analysis was used to identify associations between postural deviations and scoliosis. The adopted significance level was α = .05. Results: The SG (2.7 ± 1.9°) had greater shoulder obliquity than the FPG (1.9 ± 1.4°) (P = .010), and this deviation was associated with scoliosis (odds ratio [95% CI] P = 1.4 [1.1-1.8] 0.011). The SG had asymmetry between the right-and left-side lower limb frontal angle, shoulder sagittal alignment, and knee angle. The double curve group (3 ± 1.7°) presented a greater value of the vertical alignment of the torso than the simple curve group did (1.9 ± 1°; P = .032). Conclusions: Adolescents diagnosed with AIS in an SSS had greater shoulder obliquity and asymmetry between the right and left sides. Shoulder obliquity was the only postural deviation associated with AIS.

The aim of the study was analysis of the canonical correlations between body posture variables in the sagittal plane and scoliotic variables among school-children. The study included 28 girls aged 7-18. The Moiré photogrammetric method was used in the research. On the basis of the value of spine curvature angle, scoliotic posture: 1-9°; and scoliosis: ≥10° were distinguished. There were 21 (75%) with scoliotic posture and 7 (25%) with scoliosis. In the canonical correlation regarding body posture variables in the sagittal plane, the largest shares concerned: trunk inclination angle (0.035), alpha angle (0.072), angle of chest kyphosis (0.383), length of lumbar lordosis-(-0.301), actual angle of lumbar lordosis/total spine length (-1.067). In the canonical correlation regarding scoliotic variables, the largest shares were related to: shoulder asymmetry – right higher (-0.577), shoulder blade asymmetry – left higher (0.202), absolute pelvis tilt angle (-0.811), coefficient of shoulder...
Anthropometric Features And Postural Reactions In Children With Scoliosis And Scoliotic Posture
2017
Introduction. The aim of the research was to analyze the correlation between the anthropometric features and postural reactions in children with scoliosis and scoliotic posture. Material and method. The study included 28 girls aged 7-18 years old with scoliosis and scoliotic posture. Respondents were selected intentionally. Children attended to the Interschool Centre of Corrective Exercises in Starachowice. Height measurements were made by anthropometer, and the measurement of body weight was made with electronic scale. Those reactions were examined by static-dynamic Tecnobody's ST 310 Plus Stability System platform. Variables were verified in terms of normal distribution by Shapiro-Wilk test. Depending on the compatibility of variable distributions with normal distribution, and the value of skewness and kurtosis, parametric or non-parametric tests have been used. To determine the correlation between the anthropometric variables and postural reactions the Spearman's rank correlation coefficient has been used. The level of significance was p <0,05. Conclusions. In Romberg's test with opened eyes (OE), there were no significant correlations between the anthropometric variables and postural reactions. However, in the study with eyes closed (CE), there were significant, inversely proportional correlations between the body height and FBSD, and between the body height and AFBS. Inversely proportional correlations are understandable, because a higher children are generally slightly older, and together with age in children has been observed the reduction of postural reactions (better balance). Analysis of relationships between BMI and postural reactions with eyes closed (CE) showed a significant directly proportional correlations only with Abs AY. Higher values of BMI corresponds to the higher values of Abs AY.

Non-invasive methods of computer vision in the posture evaluation of adolescent idiopathic scoliosis
Journal of Bodywork and Movement Therapies, 2016
Url: www.fe.up.pt/\~tavares Non-invasive Methods of Computer Vision in the Posture Evaluation of Adolescent Idiopathic Scoliosis: A Systematic Review SUMMARY Purpose: Reviewing techniques for non-invasive postural evaluation of adolescent idiopathic scoliosis (AIS) based on information extraction from images based on computer methods. Methods: The Scopus, Web of Science, MEDLINE, ScieLo and PubMed databases were used, for the period 2011-2015. Results: 131 articles were found based on keyword of which 15 articles met the established eligibility criteria. Of these, 4 were based on photogrammetry, and 11 based on laser, structured light, ultrasound, and Moiré projection. In these studies, the methodological quality varied from low to high. Conclusions: The findings indicated diversity in methodologies; 14/15 articles reviewed were limited to the evaluation of the topography of the posterior back. A study, using twodimensional photogrammetry, presented a whole body postural evaluation. As the asymmetry in AIS can be extended to the whole body, more attention should be given to develop full body assessment techniques to provide important additional data to aid in treatment decisions.
The incidence of scoliotic bad posture among high school students: preliminary study
Facta universitatis. Series physical education and sport, 2011
Introduction: The available data on the incidence of scoliosis show a constant increase in the occurrence of the scoliotic bad posture, from the mid 20th century to the present. Aims: The main aims of this study were to evaluate and compare the incidence of scoliotic bad posture among the subjects in relation to their engagement in sport activities (athletes/non-athletes), gender (male/female) and handedness (right handed/left handed). Methods: The sample of subjects consisted of 240 males and females selected from a high school population whose body height was 173,55±8,74 cm, weight 64,88±10,89 kg, and age 16,76±0,91 years (Mean±St.Dev.). Frontal postural status was determined in the manner that the subjects assumed a normal upright position, and their spinal columns were overshot from the cervical (C7) vertebra to the sacral (S1) vertebra by using the “Spinal Mouse” wireless device. The existence of scoliotic bad posture to the right and to the left side was expressed by the varia...
Theoretical framework: Several spinal problems and misalignments begin during puberty and can be associated to poor posture. Objetives: To characterise the posture of children and adolescents by searching for associations with sociodemographic, behavioural, anthropometric, and clinical variables. Methodology: Cross-sectional analytical study using photogrammetry in a sample consisting of 135 participants, aged between 6 and 18 years. Results: The weight of the backpack was inadequate (>15% of body weight) in 10% of cases. The prevalence of low back pain associated to the type of footwear and Adam's test was 37.8%. Students with positive Adam's test are older, heavier, taller, more sedentary, and carry excessive weight in their backpacks. Significant gender differences were observed in the anterior view for both Q-angles, with girls tending to physiologic genu valgum). In the right and left lateral views, the results in the Adam's test varied significantly, with participants with positive Adam's test tending to a forward head posture. Conclusion: The results underline the importance of implementing programs directed to postural education. Marco contextual: muchos problemas y desalineamientos vertebrales tienen su origen en la pubertad y pueden estar asociados a una mala postura. Objetivos: caracterizar la postura de niños y adolescentes buscando asociaciones con variables sociodemográficas, comportamentales, antropométricas y clínicas. Metodología: estudio analítico de corte transversal realizado por fotogrametría en una muestra de 135 participantes con edades comprendidas entre los 6 y los 18 años. Resultados: el peso de la mochila es inapropiado (>15 % del peso corporal) en el 10 % de los casos. La prevalencia del dolor de espalda fue del 37,8 %, asociándose con el tipo de calzado y la prueba de Adams. Los alumnos con Adams positivo son mayores, presentan más peso y talla, son más sedentarios y cargan mochilas más pesadas.
