Goniometry is the measurement of joint angles with a conventional universal goniometer (UG) or a digital goniometer (DG). The UG is validated for use in dogs and cats. However, it demands both of the user's hands when measuring. To avoid this, a novel type of DG has been developed, simplifying measurement by offering single-hand usage. The objective of this study is to examine the concurrent validity of the DG. The study consists of measurement with the DG and UG for flexion of the carpus and fetlock on ten horses, and with the DG in flexion and neutral positioning of the fetlock on a sedated horse and corresponding radiographs, intra- and inter-tester reliability and a survey on user-friendliness. The data were analyzed with ANOVA and intraclass correlation coefficient (ICC), with a significance of < 0.05. The study showed significant differences in range of motion for the carpus and fetlock joint, a 2-3° difference comparing measurements on a sedated horse with corresponding radiographs, a "fair" to "excellent" inter-tester reliability and a "fair" to "almost perfect" intra-tester reliability, and the DG was easier to use than the UG. In conclusion, the novel DG may serve as a simple tool for measuring joint motion in equine rehabilitation patients.
关节角度测量法是使用传统通用关节角度测量仪（UG）或数字关节角度测量仪（DG）来测量关节角度。UG已被验证可用于犬猫。然而，测量时需要使用者双手操作。为避免这一问题，已开发出一种新型DG，通过单手操作简化了测量过程。本研究的目的是检验DG的同时效度。该研究包括对10匹马的腕关节和跗关节屈曲进行DG和UG测量，对一匹镇静马的跗关节屈曲和中立位进行DG测量并拍摄相应的X光片，评估测试者内和测试者间的可靠性以及对用户友好性进行调查。采用方差分析和组内相关系数（ICC）对数据进行分析，显著性水平为<0.05。研究表明，腕关节和跗关节的活动范围存在显著差异，对镇静马的测量与相应X光片相比有2 - 3°的差异，测试者间可靠性为“中等”至“优秀”，测试者内可靠性为“中等”至“几乎完美”，且DG比UG更易于使用。总之，新型DG可作为测量马类康复患者关节活动的简单工具。
