本研究探讨三种角度计，通用，流体，和电子角度计，在测量踝关节背屈的可靠性。使用10名健康志愿者和5名观察者评估观察者内和观察者间的可靠性。标准化踝关节位置用于测量主动背屈的全范围。使用一名观察者连续两次评估观察者内可靠性。在5个不同的观察者中评估观察者间的可靠性，单因素方差分析检查观察者内的可靠性，结果表明两种情况下每种器械之间没有显著差异。多因素方差分析显示观察者之间以及器械之间存在显著差异（P < 0.001）。器械间可靠性的二次分析表明，三种器械之间存在显著差异（p < 0.1）。该研究表明，每种器械不能在观察者之间可靠使用或互换使用，如果不遵循严格的协议，基于角度变化小于10度的临床判断是无效的。
This study investigated the reliability of three goniometers, the universal, fluid, and electro-goniometers, in the measurement of ankle dorsiflexion. Intra- and interobserver reliability were assessed using 10 healthy volunteers and five observers. A standardized ankle position was used to measure full range of active dorsiflexion. Intraobserver reliability was assessed using one observer over two successive occasions. Interobserver reliability was assessed among five observers over five separate occasions.A one-factor analysis of variance to examine intraobserver reliability demonstrated no significant difference between each of the devices on the two occasions. A multifactorial analysis of variance demonstrated significant differences among observers and again among devices (P < 0.001). Secondary analysis for interdevice reliability demonstrated significant differences among the three devices (p < 0.1). The study suggests that each device cannot be used reliably among observers or be used interchangeably, and clinical judgment based on angular changes of less than 10 degrees are invalid if rigid protocols are not followed.
