The reliability of a modified protocol for plotting the instantaneous axes of sagittal rotation for the cervical spine was evaluated by measuring the observer differences when the process was performed separately by two observers, and by a single observer, on two separate occasions. Small observer differences were found both for individual steps in the process and for the process as a whole. These differences were substantially less than those found using the conventional technique for plotting the instantaneous axes of rotation. The improvement in the technique was resultant from the use of stricter criteria for recognizing and tracing vertebral landmarks.
通过测量两名观察者分别进行以及一名观察者在两个不同场合单独进行该过程时的观察者差异，对一种用于绘制颈椎矢状面旋转瞬时轴的改良方案的可靠性进行了评估。在该过程的各个步骤以及整个过程中均发现观察者差异较小。这些差异明显小于使用传统技术绘制旋转瞬时轴时所发现的差异。该技术的改进源于使用了更严格的标准来识别和追踪椎体标志。
