An analysis of literature on the methods of assuming a sitting position and the results of our own research indicated the need to search for biomechanical parameters and existing relationships that would enable a description of sitting body posture. The purpose of this paper is to analyze the relationship between the alignment of the body of sternum and sacrum and the changes in the thoracic and lumbar spine curvatures in children. The study involved 113 subjects aged 9-13 years. A planned simultaneous measurement of the angle parameters of the alignment of the body of sternum and sacrum relative to the body's sagittal axis and the angle parameters of the thoracic and lumbar spine curvatures was performed during a single examination session. The proposed markers of alignment in the corrected sitting body posture are characterized by homogeneous results. A high measurement repeatability was observed when determining the corrected body posture in the study setting. It was noted that changes in the alignment of the body of sternum and sacrum resulted in changes in the thoracic kyphosis and lumbar lordosis angle values, which may be an important component of clinical observations of sitting body posture in children. Implementing the body of sternum alignment angle of about 64° relative to the body's sagittal axis in clinical practice as one of the objectives of postural education may be the target solution for sitting body posture correction in children.
对有关坐姿方法的文献进行分析以及我们自己的研究结果表明，需要寻找能够描述坐姿的生物力学参数和现有关系。本文旨在分析胸骨和骶骨体排列与儿童胸腰椎曲度变化之间的关系。研究涉及 113 名 9-13 岁的受试者。在单次检查过程中，计划同时测量胸骨和骶骨体相对于身体矢状轴的排列角度参数以及胸腰椎曲度的角度参数。在纠正坐姿中，提出的排列标记具有均匀的结果。在研究环境中确定纠正的身体姿势时，观察到较高的测量可重复性。注意到胸骨和骶骨体排列的变化导致胸腰椎曲度角值的变化，这可能是儿童坐姿观察的重要组成部分。在临床实践中，将胸骨体排列角度约为 64°相对于身体矢状轴作为姿势教育的目标之一实施，可能是儿童坐姿矫正的目标解决方案。
