The purpose of this study was to investigate the inter-tester reliability of lumbar lordosis posture using a novel screening device.
A total of 33 healthy young male participants participated in the study. Two examiners measured the regional upper and lower lumbar lordosis angles of the participants in the standing position using a flexible ruler. The bent flexible ruler maintained a fixed shape and was transferred to a protractor for angle measurement. Two examiners classified each participant into one of 4 lumbar spine categories and measured the upper and lower regional lumbar lordosis angles.
The agreement level between the 2 examiners in assessing healthy participants was 87.9%. The calculated kappa coefficient was 0.79 (95% CI = 0.86-0.97), reflecting a substantial level of agreement.
Our results suggest that our novel screening device for assessing upper and lower lumbar angles showed good inter-tester reliability in posture classification. Our findings may be useful for health care professionals for managing sagittal lumbar posture in asymptomatic younger individuals; however, more testing is still needed.
本研究旨在探讨一种新型筛查设备测量腰椎前凸姿势的组内可靠性。
共有 33 名健康年轻男性参与了本研究。两名检查者使用柔性标尺测量参与者站立位的局部上、下腰椎前凸角度。弯曲的柔性标尺保持固定形状，并转移到量角器上进行角度测量。两名检查者将每个参与者分为 4 个腰椎脊柱类别之一，并测量上、下局部腰椎前凸角度。
评估健康参与者时，两名检查者的一致性水平为 87.9%。计算的kappa 系数为 0.79（95%置信区间=0.86-0.97），反映了高度一致的水平。
我们的结果表明，我们评估上、下腰椎角度的新型筛查设备在姿势分类方面具有良好的组内可靠性。我们的发现可能对管理无症状年轻个体矢状位腰椎姿势的医疗保健专业人员有用；但是，仍需要更多的测试。
