[Purpose] Poor posture in children and adolescents is a well-known problem. Therefore, early detection of incorrect posture is important. Photometric posture analysis is a cost-efficient and easy method, but needs reliable reference values. As children's posture changes as they grow, the assessment needs to be age-specific. This study aimed to investigate the development of both one-dimensional posture parameter (body inclination angle) and complex parameter (posture index) in different age groups (childhood to adolescence). [Subjects and Methods] The participants were 372 symptom-free children and adolescents (140 girls and 232 boys aged 6-17). Images of their habitual posture were obtained in the sagittal plane. High-contrast marker points and marker spheres were placed on anatomical landmarks. Based on the marker points, the body inclination angle (INC) and posture index (PI) were calculated using the Corpus concepts software. [Results] The INC angle significantly increased with age. The PI did not change significantly among the age groups. No significant differences between the corresponding age groups were found for PI and INC for both sexes. [Conclusion] When evaluating posture using the body inclination angle, the age of the subject needs to be considered. Posture assessment with an age-independent parameter may be more suitable.
[目的]儿童和青少年的不良姿势是一个众所周知的问题。因此，早期发现不正确的姿势很重要。光度学姿势分析是一种经济高效且简便的方法，但需要可靠的参考值。由于儿童的姿势会随着生长而变化，评估需要针对特定年龄。本研究旨在调查不同年龄组（儿童期至青少年期）一维姿势参数（身体倾斜角度）和复杂参数（姿势指数）的发展情况。[对象与方法]参与者为372名无症状儿童和青少年（140名女孩和232名男孩，年龄6 - 17岁）。在矢状面获取他们习惯性姿势的图像。在解剖学标志点上放置高对比度标记点和标记球。基于标记点，使用人体概念软件计算身体倾斜角度（INC）和姿势指数（PI）。[结果]INC角度随年龄显著增加。各年龄组之间PI没有显著变化。男女相应年龄组的PI和INC均未发现显著差异。[结论]使用身体倾斜角度评估姿势时，需要考虑受试者的年龄。使用与年龄无关的参数进行姿势评估可能更合适。
