RESUMO

During the infancy, the posture undergoes many adjustments related to growth stages due to changes of the body proportions. The formation of the body schema, in childhood, occurs through the motor experiences and allows the tonic-postural structuring, and the postural imbalance acquired in this period can last for the entire adolescence and adult life. The purpose of this study was to characterize quantitatively the posture of children between 7 and 8 years of age and to verify the difference between sex and age for the analyzed postural aspects. Two hundred and thirty children between 7 and 8 years of Amparo/SP city public schools were assessed. The posture evaluation was made through subjects digital photos in orthostatic position and analyzed with the CorelDraw® v. 10.0 software guidelines and the bony landmarks. The following segments were measured - ankle, knee, pelvis, lumbar, thoracic, shoulder, scapula and head, besides lateral spine deviation, fingertip-to-floor test and footprint. Data were analyzed using descriptive statistic (average, standard deviation and percentage) and ANOVA models to verify differences among the groups, adopting alfa of 5%. It was found average values and confidence intervals to the analyzed variables. Some of these variables showed differences to sex, as fingertip-to-floor test, head posture, footprint and intermalleolar distance. The other ones showed significant difference to age - thoracic kyphosis and shoulder in the frontal plane. To lumbar lordosis, boys of 7 years of age showed average value of 38,49o±15,32 and the other children 42,29o±7,13. The scapula posture showed influence of the factors sex and age, girls of 7 years of age showed average value of 5,29cm±1,82 and the one of 8 years 5,67cm±1,82, boys of 7 years of age showed 5,74cm±1,97 and the one of 8 years 6,12cm±1,97. The other analyzed variables do not showed influence of sex and age and they formed only a group with all the studied children - ankle posture (6,67o±4,25), knee in the sagittal plane (184,28o±5,46), pelvic inclination (15,82o±5,46), shoulder in the sagittal plane (6,76cm±1,52), lateral spine deviation (3,48o±2,12) and intercondylar distance (1,14cm±1,36). To the fingertip-to-floor test, girls showed average value of 29,15cm±8,80 while boys showed 27,41cm±10,01 and, to head posture, girls presented average angle of 49,55o±6,67 and boys of 52,16o±7,58. The footprint average values, measured by the Chipaux-Smirak Index, classified the foot, as of the girls ones (21,02%±19,71) as the boys (26,31%±22,44), with normal morphologically arch. To thoracic kyphosis, children of 7 years of age showed 28,07o±7,73 and ones of 8 years of age 30,32o±7,73. It was not identify a pattern of postural symmetry to the studied sample and it was found differences between sex and age for some of the analyzed segments. The values found in this study may help in the physiotherapy treatment when they are associated with other aspects of the clinical assessment and symptomatology.
