Civilization development coupled with contemporary lifestyle leads to a systematic increase in postural disorders. An analysis of factors that may provoke postural disorders indicates that such a stimulus may be the diastasis of the rectus abdominis muscles. Moreover, abnormal activity of the rectus abdominis muscles may affect balance disorders through reduced spinal stabilization and disturbed body statics. There is an increase in body posture abnormalities between the ages of 6 and 9 related to new school duties.
The purpose of the study was to evaluate the relationship between the shape of the spine and the width of the linea alba in children aged 6-9 years.
The study was designed to evaluate parameters determining the shape of the spine, and the width of the linea alba in healthy children aged 6-9 years. The study participants were divided into two groups based on the width of the linea alba. The study group with the width of the linea alba >10 mm and the control group with the width of the linea alba ≤ 10 mm. The study group were included 37 children and the control group 24 children. The examination of the linea alba width was performed by a radiology specialist using a linear transducer and SAOTE- My Lab Classc-type ultrasound at rest and during contraction of the rectus abdominis muscles. Parameters describing the shape of the spine were measured using the Diers Formetric 4D system: trunk inclination, trunk imbalance, pelvis tilt, pelvic torsion, kyphotic apex, lordotic apex, kyphotic angle, lordotic angle, rotation angle, trunk torsion, lateral deviation. The obtained results were statistically analyzed using a Paired test for comparison of differences between the results in the study and control groups and Pearson's test to assess the correlation between the width of the linea alba and parameters describing spinal alignment.
In both groups, the parameters describing the shape of the spine did not differ from the norms accepted as typical for the age norm. The only statistically significant difference between the study and control group concerned the trunk inclination, which was negative in the study group, signifying a shift of the entire spine axis backwards beyond the vertical.
There is a correlation between the shape of spine and the width of the linea alba in terms of selected parameters determining the body posture in the sagittal plane, which concern: the position of the lumbar lordotic apex, trunk inclination and the depth of the lumbar lordotic angle. The width of the linea alba is not explicitly related to abnormalities of pelvic and spinal alignment in the frontal and transverse planes.
文明的发展与当代生活方式导致姿势障碍系统性增加。对可能引发姿势障碍的因素分析表明，腹直肌分离可能是这样一种刺激因素。此外，腹直肌的异常活动可能通过降低脊柱稳定性和扰乱身体静态平衡而影响平衡障碍。6至9岁儿童因新的学业任务，身体姿势异常有所增加。
本研究的目的是评估6至9岁儿童脊柱形状与白线宽度之间的关系。
本研究旨在评估确定6至9岁健康儿童脊柱形状和白线宽度的参数。研究参与者根据白线宽度分为两组。白线宽度>10毫米的研究组和白线宽度≤10毫米的对照组。研究组包括37名儿童，对照组包括24名儿童。白线宽度检查由放射科专家在腹直肌休息和收缩时使用线性换能器和SAOTE - My Lab Classc型超声进行。使用迪尔斯4D系统测量描述脊柱形状的参数：躯干倾斜度、躯干不平衡、骨盆倾斜、骨盆扭转、后凸顶点、前凸顶点、后凸角、前凸角、旋转角、躯干扭转、侧弯。对获得的结果进行统计学分析，使用配对检验比较研究组和对照组结果之间的差异，并使用皮尔逊检验评估白线宽度与描述脊柱排列参数之间的相关性。
在两组中，描述脊柱形状的参数与被接受为该年龄标准典型值的规范没有差异。研究组和对照组之间唯一具有统计学意义的差异涉及躯干倾斜度，研究组中该值为负，表明整个脊柱轴向后偏移超过垂直线。
就确定矢状面身体姿势的选定参数而言，脊柱形状与白线宽度之间存在相关性，这些参数包括：腰椎前凸顶点的位置、躯干倾斜度和腰椎前凸角的深度。白线宽度与额面和横面的骨盆及脊柱排列异常没有明确关系。
