In order to assess the reproducibility of two standard techniques of measuring forearm rotational movements, three trained observers used each method on twenty healthy volunteers. Analysis of the result obtained revealed no statistical difference between either method but both were subject to wide variation between observers, amounting to plus or minus 15 degrees for total forearm rotation. Comparison of individual values in forearm rotation should take account of observer error.
为了评估两种测量前臂旋转运动的标准技术的可重复性，三名训练有素的观察者对20名健康志愿者分别使用了这两种方法。对所得结果的分析显示，两种方法之间没有统计学差异，但两种方法在观察者之间都存在很大差异，前臂总旋转角度可达正负15度。在前臂旋转中比较个体值时应考虑观察者误差。
