Children's postural alignment undergoes many adjustments due to the changes in body proportions during the stages of growth. The objective of this study was to quantitatively characterize and analyze spinal postural standards in 7- and 8-year-old children to verify which of the differences found were correlated to age and sex.
Two hundred thirty public school students (Amparo, São Paulo, Brazil) aged 7 to 8 years were divided into groups according to postural alignment, which were further subdivided by sex and age, for comparison. Digital photos of upright subjects were analyzed to evaluate posture. Lumbar and thoracic curvature, pelvic inclination, head posture, and lateral spine deviation were measured using CorelDraw (Ottawa, Canada) software guidelines and bone landmarks. Descriptive statistics and analysis of variance data analysis were utilized to verify differences among the groups. This was a cross-sectional, descriptive study.
Mean values for the variables analyzed were calculated. For lumbar lordosis, 7-year-old boys showed 38.49 degrees +/- 15.32 degrees in comparison to all other groups (42.29 degrees +/- 7.13 degrees ). For thoracic kyphosis, the 7-year-old children presented 28.07 degrees +/- 7.73 degrees , and the 8-year-olds 30.32 degrees +/- 7.73 degrees . Pelvic inclination presented a mean value of 15.82 degrees +/- 5.46 degrees and single lateral spine deviation mean value of 3.48 degrees +/- 2.12 degrees .
For the sample studied, differences based on sex and age were found for some of the body segments analyzed. The values found in this study may contribute to improved physiotherapeutic treatment when associated with other aspects of the clinical assessment and symptomatology.
在生长阶段，儿童的身体比例会发生变化，其姿势排列也会经历许多调整。本研究的目的是定量表征和分析7至8岁儿童的脊柱姿势标准，以验证所发现的差异中哪些与年龄和性别相关。
230名7至8岁的公立学校学生（巴西圣保罗安帕罗）根据姿势排列分组，再按性别和年龄进一步细分，以便进行比较。对直立受试者的数码照片进行分析以评估姿势。使用CorelDraw（加拿大渥太华）软件指南和骨骼标志点测量腰椎和胸椎曲度、骨盆倾斜度、头部姿势和脊柱侧弯度。采用描述性统计和方差数据分析来验证各组之间的差异。这是一项横断面描述性研究。
计算了所分析变量的平均值。对于腰椎前凸，7岁男孩为38.49度±15.32度，与所有其他组（42.29度±7.13度）相比。对于胸椎后凸，7岁儿童为28.07度±7.73度，8岁儿童为30.32度±7.73度。骨盆倾斜度的平均值为15.82度±5.46度，脊柱侧弯度的平均值为3.48度±2.12度。
对于所研究的样本，在所分析的一些身体部位发现了基于性别和年龄的差异。本研究中发现的值与临床评估和症状学的其他方面相关联时，可能有助于改善物理治疗。
