Análise do alinhamento dos membros inferiores em crianças com excesso de peso. DOI: 10.5007/1980-0037.2011v13n2p124

Abstract

Resumo -O sobrepeso e a obesidade (SO) têm atingido proporções epidêmicas, principalmente, em idade escolar, tornando-se um problema mundial de saúde. Muitas adaptações podem ocorrer na organização postural de crianças com SO, provocando, graves consequências. A avaliação postural pode colaborar para o entendimento destas alterações. O objetivo do presente estudo foi verificar alterações na postura dos membros inferiores de crianças com SO, através de metodologia específica. Vinte e dois indivíduos, sendo distribuídos de acordo com o sexo: 9 do feminino e 13 do masculino, com faixa etária entre 5-9 anos, participaram do estudo. Na avaliação postural, foram utilizados a fotogrametria e o software SAPo. Foram analisados os ângulos articulares dos membros inferiores e a projeção plantar do centro de gravidade. Foi utilizada estatística não-paramétrica descritiva, além dos testes de Kruskal-Wallis e de Mann-Whitney (p<0,05), para comparação entre os sexos. Ambos os sexos apresentaram anteroversão e leve rotação pélvica, à direita para o feminino e à esquerda para o masculino hiperextensão e valgismo de joelhos e valgismo tornozelos. O centro de gravidade apresentou 26,95% de anteriorização. Conclui-se que a avaliação postural nessa população foi congruente aos achados da literatura e a metodologia utilizada possibilitou quantificar os dados para futuras comparações.

Low Back Pain in Adolescents: A School Screening

“…13,14 In the prepubertal and pubertal period, obesity may be related to postural imbalances caused by mechanical overload in the locomotor system, which interfere with the postural pattern due to anterior displacement of the centre of gravity, resulting in postural deviationswhich can cause pain and possible musculoskeletal deformities. 15,16 In this sense, a study conducted on schoolchildren between 6 and 12 years old, enrolled in a public school in the city of Uberaba/Minas Gerais has shown that obesity and being overweight produce changes in posture, balance and ability to perform everyday activities, and that 61.7% of students had postural changes related to thelower back. 17 Importantly, most bad postural habits are established during growth and sexual maturation phases, respectively, in childhood and adolescence, causing postural changes, particularly lateral and anterior-posterior changes, which can also be related to sitting posture, either when attending school or to watching TV.…”

Influência do perfil nutricional e da atividade física na postura de crianças e adolescentes

“…Obesity predisposes an individual to the alteration of the valgus knee for the realignment of the extremity due to fat accumulation in the medial region of the knees, which causes a knee hyperextension because of the internal rotation of the femur 15 . Furthermore, it is associated with head protraction 1 and instabilities of feet joints 16 . These changes can cause compensations in other areas of the body 16 and result in pain, lack of mobility, and body biomechanical inefficacy 15 .…”

“…Furthermore, it is associated with head protraction 1 and instabilities of feet joints 16 . These changes can cause compensations in other areas of the body 16 and result in pain, lack of mobility, and body biomechanical inefficacy 15 . A good posture in childhood and adolescence has great importance, given that the incorrect alignment of the body segments is a risk factor for injuries in sports practice 17 .…”

“…In addition, the majority of researches are limited to the evaluation of the lower limb alignment through angles that indicate rotations, valgus and varus deformities, and pelvis positioning 16,18,19 . Body alignment analysis may provide subside in order that postural changes will work globally in the clinical practice.…”
