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.
本研究调查了通用型、流体型和电子测角仪这三种测角仪在测量踝关节背屈时的可靠性。使用10名健康志愿者和5名观察者评估了观察者内和观察者间的可靠性。采用标准化的踝关节位置来测量主动背屈的全范围。观察者内可靠性通过一名观察者在两个连续的场合进行评估。观察者间可靠性在5名观察者的五个不同场合进行评估。用于检验观察者内可靠性的单因素方差分析表明，在两个场合中各设备之间没有显著差异。多因素方差分析表明观察者之间以及设备之间存在显著差异（P<0.001）。设备间可靠性的二次分析表明三种设备之间存在显著差异（p<0.1）。该研究表明，每种设备在观察者之间不能可靠使用，也不能互换使用，如果不遵循严格的方案，基于小于10度的角度变化的临床判断是无效的。
