The aim of this study is to prove the intra- and interobserver reliability of three different methods to measure the active range-of-motion in the forearm.
These three different methods were tested on forty volunteers. In the first method pictures were made in full supination and pronation, measurement of the two angles was performed with a dedicated software. Active range-of-motion was defined as the magnitude of forearm rotation between maximum pronation and supination. The second method used a standard goniometer. The third method of assessment used a gravity goniometer (plurimeter). We randomised both the side of the patient to be examined and the sequence of the methods. Two examiners measured subsequently the range-of-motion twice with these three devices.
We found a significant intraobserver reproducibility with the gravity goniometer. There was no significance with the goniometer or pictures. The intraobserver reproducibility of the latter two methods was poor. The interobserver reproducibility of the gravity goniometer and pictures was significant, for the goniometer it was poor. Agreement between the pictures and gravity goniometer assessment of the range-of-motion was good. None of these two methods was significantly correlated with the goniometer assessment.
For reproducibility of measurement of range-of-motion in the forearm the gravity goniometer is the best method, although the measured values were 5 % greater.
本研究旨在证明三种不同方法测量前臂主动活动范围时观察者内和观察者间的可靠性。
对40名志愿者测试了这三种不同方法。第一种方法是在完全旋前和旋后时拍照，使用专用软件测量两个角度。主动活动范围定义为前臂在最大旋前和旋后之间的旋转幅度。第二种方法使用标准测角仪。第三种评估方法使用重力测角仪（多关节角度测量仪）。我们对要检查的患者侧别和方法顺序进行了随机化。两名检查者随后使用这三种设备对活动范围进行了两次测量。
我们发现重力测角仪具有显著的观察者内可重复性。测角仪或照片测量结果无显著性差异。后两种方法的观察者内可重复性较差。重力测角仪和照片的观察者间可重复性显著，测角仪的观察者间可重复性较差。照片和重力测角仪对活动范围的评估之间一致性良好。这两种方法与测角仪评估均无显著相关性。
对于前臂活动范围测量的可重复性，重力测角仪是最佳方法，尽管测量值大5%。
