In this paper the SpinalMouse, a new computerised external device for measuring sagittal spinal range of motion (ROM), was tested for inter-rater reliability and use in clinical practice.
To assess inter-rater reliability, two investigators each measured 111 subjects.
Correlation coefficients were found to be r=0.90 for flexion, r=0.85 for extension and r=0.90 for total inclination. Intra-class coefficients were 0.95 for flexion, 0.92 for extension and 0.95 for total inclination. A poor agreement (kappa=0.22) was found for the presence of outliers from normal values for intersegmental ROM.
We conclude the device is a useful, reliable tool for measuring sagittal spinal ROM in clinical practice, considering the small load it confers on patients and the short amount of time the measurement involves. The SpinalMouse might be more accurate after following the recommendations we make.
在本文中，对一种用于测量脊柱矢状面活动范围（ROM）的新型计算机化外部设备SpinalMouse进行了评分者间信度测试及临床应用测试。
为评估评分者间信度，两名研究者分别对111名受试者进行了测量。
发现屈曲时的相关系数r = 0.90，伸展时r = 0.85，总倾斜度时r = 0.90。组内相关系数屈曲时为0.95，伸展时为0.92，总倾斜度时为0.95。对于节段间ROM偏离正常值的异常值存在情况，一致性较差（kappa = 0.22）。
我们得出结论，考虑到该设备给患者带来的负荷较小且测量所需时间较短，它是临床实践中测量脊柱矢状面ROM的一种有用且可靠的工具。遵循我们提出的建议后，SpinalMouse可能会更准确。
