Resumo
O presente estudo teve por objetivo contribuir para a melhora dos métodos de aquisição e processamento dos dados em fotogrametria para análise da postura, desenvolvendo para isso uma adaptação de baixo custo nos marcadores de superfície para estimar as curvaturas da coluna vertebral no plano sagital, buscar evidências e correlações da postura da coluna vertebral com a postura corporal e com os tipos de pés em escolares. A metodologia utilizou marcadores de superfície e hastes de prolongamento nos processos espinhosos das vértebras torácicas e lombares para determinar as relações e os valores angulares, utilizando o programa CorelDRAW X5®. A classificação dos tipos de pés foi realizada através das impressões plantares em papel utilizando o método descrito por Cavanagh e Rodgers (1987). As médias angulares da coluna vertebral e da postura foram comparadas e correlacionadas entre si bem como com os tipos de pés e com os dados antropométricos através dos testes de t Student, ANOVA, Kuskal-Wallis e Coeficiente de Correlação de Pearson. Para todo o estudo o nível de significância estatístico adotado foi 5%. Participaram do estudo 49 escolares com idade média de 8 anos e 5 meses, sem qualquer indício de patologia ortopédica e/ou neurológica. Nesta amostra não foi possível correlacionar a postura da coluna vertebral no plano sagital com os ângulos estimados da postura corporal, tampouco com a classificação do arco longitudinal medial. Entretanto, foi possível evidenciar que o aumento do ângulo de inclinação torácica leva à diminuição do ângulo de inclinação lombar no plano sagital e que a protrusão de cabeça pode gerar uma maior tendência ao padrão de flexão de cabeça, sendo possível em raciocínio inverso. Notou-se, ainda, que nas crianças acima do peso ocorreu o aumento do ângulo de inclinação lombar
This study aimed to contribute to the improvement of methods of data acquisition and processing in photogrammetry for the analysis of posture, developing a low cost adaptation in surface markers to estimate the curvatures of the spine in the sagittal plane, search for evidence and correlations of spinal posture with the body posture and with the types of feet in schoolchildren. The methodology used surface markers and extension rods in the spinous processes of the thoracic and lumbar vertebrae to determine the relationships and angular values using the program CorelDRAW X5®. The classification of types of feet was performed by the footprints on paper using the method described by Cavanagh and Rodgers (1987). The mean angles of the spine and posture were compared and correlated among themselves and with the types of feet and anthropometric data through the Student t test, ANOVA, Kruskal-Wallis and Pearson Correlation Coefficient. For the entire study the level of statistical significance adopted was 5%. The study included 49 schoolchildren with mean age of 8 years and 5 months with no evidence of orthopedic and / or neurological pathology. In this sample was not possible to correlate the spine posture in the sagittal plane with the estimated angles of body posture nor with the classification of the medial longitudinal arch. However, it was observed that the increase in the inclination of chest angle leads to a decrease in the inclination of lumbar angle in the sagittal plane and the protrusion of the head can generate a greater tendency to the standard of flexion of the head, it being possible for reverse reasoning. It is also noted that in overweight children occurred increasing in the inclination of lumbar angle
