The dynamic anterior ankle tester (DAAT) has shown a good reliability in testing anterior talar translation in earlier studies. The goal of the present study was first to evaluate the reliability of the DAAT in a clinical setting and second to analyze its ability to detect increased ligament laxity. In 39 patients with unilateral chronic lateral ankle instability, the anterior talar translation of the affected and non-affected side was measured pre and postoperatively using the DAAT, Telos stress radiographs, and the manual anterior drawer test. In contrast to both other tests, the DAAT was not able to accurately detect increased ligament laxity preoperatively or decreased laxity of the affected ankle postoperatively. The DAAT showed a low sensitivity to change (the difference between the mean pre and postoperative value) and a low reliability compared to both other tests. There were no correlations between the three tests. In conclusion, the DAAT showed a low reliability in effectively testing lateral ankle ligament laxity in a clinical setting. This is in contrast to earlier evaluations.
动态前踝测试仪（DAAT）在早期研究中已显示出在前距骨平移测试方面具有良好的可靠性。本研究的目的首先是评估 DAAT 在临床环境中的可靠性，其次是分析其检测韧带松弛度增加的能力。在 39 例单侧慢性外侧踝关节不稳定的患者中，使用 DAAT、Telos 应片和手动前抽屉试验分别在术前和术后测量患侧和健侧的前距骨平移。与其他两种测试不同，DAAT 术前不能准确检测到韧带松弛度增加，术后也不能检测到患侧踝关节松弛度降低。与其他两种测试相比，DAAT 的变化敏感性（术前和术后平均值之间的差异）较低，可靠性也较低。三种测试之间无相关性。总之，DAAT 在临床环境中有效测试外侧踝关节韧带松弛度的可靠性较低。这与早期的评估结果相反。
