The adapted arcometer has been validated for use in adults. However, its suitability for use in children can be questioned given the structural differences present in these populations.
To verify the concurrent validity, repeatability, and intra- and inter-reproducibility of the adapted arcometer for the measurement of the angles of thoracic kyphosis and lumbar lordosis in children.
Forty children were evaluated using both sagittal radiography of the spine and the adapted arcometer. The evaluations using the arcometer were carried out by two trained evaluators on two different days. In the statistical treatment, the intraclass correlation coefficient (ICC), Pearson's product moment correlation, Spearman's rho, the paired t test, and Wilcoxon's test were used (α=.05).
A moderate and significant correlation was found between the x-ray and the adapted arcometer regarding thoracic kyphosis, but no correlation was found regarding lumbar lordosis. Repeatability and intra-evaluator reproducibility of the thoracic kyphosis and lumbar lordosis were confirmed, which was not the case of inter-evaluator reproducibility.
The adapted arcometer can be used to accompany postural alterations in children made by the same evaluator, while its use for diagnostic purposes and continued evaluation by different evaluators cannot be recommended. Further studies with the aim of adapting this instrument for use in children are recommended.
改良后的角度计已被验证可用于成人。然而，鉴于儿童与成人在结构上存在差异，其在儿童中的适用性值得怀疑。
验证改良后的角度计测量儿童胸椎后凸角和腰椎前凸角的同时效度、重复性以及评估者内和评估者间的再现性。
对40名儿童进行了脊柱矢状面X线摄影和使用改良后的角度计的评估。角度计评估由两名经过培训的评估者在两个不同日期进行。在统计处理中，使用了组内相关系数（ICC）、皮尔逊积矩相关、斯皮尔曼等级相关、配对t检验和威尔科克森检验（α = 0.05）。
在胸椎后凸方面，X线摄影与改良后的角度计之间存在中度且显著的相关性，但在腰椎前凸方面未发现相关性。胸椎后凸和腰椎前凸的重复性以及评估者内再现性得到了证实，但评估者间再现性未得到证实。
改良后的角度计可用于同一评估者对儿童姿势改变的跟踪监测，但不建议将其用于诊断目的以及由不同评估者进行持续评估。建议开展进一步研究，旨在使该仪器适用于儿童。
