摘要：

      摘要 目的：评价Scoligauge作为脊柱侧凸筛查工具的可靠性。 方法：6名具有多年脊柱侧凸筛查经验的医师和治疗师分别利用安装Scoligauge软件的iPhone手机和传统的脊柱测量仪脊柱侧凸测量仪（scoliometer）对27例确诊为特发性脊柱侧凸的青少年患者，男10例，女17例，平均年龄12.8岁，进行躯干倾斜角度的测量，每例患者接受每周1次，共4次测量。通过分析两种测量手段的观测值差异和95%置信区间，以及组内相关系数来评估Scoligauge的测量信度。 结果：Scoligauge与脊柱侧凸测量仪测量得到的躯干倾斜角配对绝对差为2.5°±1.4°，差异的95%置信区间为±2.9°。Scoligauge的组内相关系数值为0.915，脊柱侧凸测量仪的组内相关系数值为0.932。 结论：Scoligauge与脊柱侧凸测量仪在脊柱侧凸测量上可视为等效工具。

Abstract:

      Abstract Objective: To evaluate the reliability of rib hump measurement in scoliosis with Scoligauge. Method: Six experienced doctors and physiotherapists (observer) measured the rib hump angles of the 27 patients (10 males and 17 females with average age of 12.8yr.) with adolescent idiopathic scoliosis using the scoliometer and the iPhone with Scoligauge application software. Every patients received one measurement per week and total four measurements performed in four weeks. Measurement difference between pairs of iPhone/scoliometer measurements and 95% confidence intervals were calculated. The intraclass correlation coefficients (ICC) were calculated for repeated measurements of each patient by observers. Result: Absolute difference of rib hump measurements between pairs of Scoligauge/scoliometer was (2.5±1.4) degrees, the 95% confidence interval for differences on the same subject was ±2.9 degrees. The ICC were 0.915 (Scoligauge) and 0.932 (scoliometer). Conclusion: The iPhone using Scoligauge is a clinically equivalent rib hump measurement tool to the scoliometer in spinal deformity patients.
