The aim of this study was to evaluate the validity of the Veloflex infrared dynamic angle-meter (Veloflex-IDA) and the intra- and inter-rater reliability when measuring the ranges of motion (ROMs) of the upper limb joints. Thirty-five healthy and 20 symptomatic participants were evaluated. Twelve upper limb movements were measured in two sessions with the Veloflex-IDA, which is a device composed of a camera that tracks the trajectory of retro-reflective markers. In addition, a goniometer was used in the first session to evaluate concurrent validity. Validity and agreement were evaluated by Pearson correlation coefficient (r) and Bland-Altmann plots. Intra- and inter-rater reliability were evaluated using intra-class correlation (ICC), standard error of measurement (SEM), and minimal detectable change (MDC). Both instruments showed excellent correlation for all movements ( range from 0.992 to 0.999). The intra- and inter-rater reliability were excellent (ICC range from 0.95 to 0.99 and 0.90 to 0.98, respectively). Intra-rater reliability showed SEMs <1.38% and <5.19% and inter-rater reliability SEMs <2.26% and <5.22% for asymptomatic and symptomatic, respectively. Veloflex-IDA is a valid and reliable alternative to measure the upper limb joints' ROM and it can be used in clinical practice and research after basic training.
本研究的目的是评估Veloflex红外动态角度计（Veloflex-IDA）在测量上肢关节活动范围（ROM）时的有效性以及评分者内和评分者间的可靠性。对35名健康参与者和20名有症状的参与者进行了评估。使用Veloflex-IDA在两个阶段测量了12种上肢运动，该设备由一个跟踪反光标记轨迹的摄像头组成。此外，在第一阶段使用了角度计来评估同时效度。通过Pearson相关系数（r）和Bland-Altmann图评估效度和一致性。使用组内相关系数（ICC）、测量标准误差（SEM）和最小可检测变化（MDC）评估评分者内和评分者间的可靠性。两种仪器对所有运动均显示出极好的相关性（范围为0.992至0.999）。评分者内和评分者间的可靠性都非常好（ICC范围分别为0.95至0.99和0.90至0.98）。对于无症状和有症状的参与者，评分者内可靠性的SEM分别<1.38%和<5.19%，评分者间可靠性的SEM分别<2.26%和<5.22%。Veloflex-IDA是测量上肢关节ROM的一种有效且可靠的替代方法，经过基础培训后可用于临床实践和研究。
