The purposes of this repeated-measures single-case-design study were to describe goniometric placement preferences and their effect on the measurement of the proximal and distal interphalangeal joints, to determine interrater reliability, and to determine concurrent validity. Thirty-nine therapists measured one patient dorsally and laterally with the DeVore and the 6" clear goniometers. No significant differences were found between the two goniometers used in the study. Comparison of the means of lateral and dorsal measurements revealed that the only joint associated with a significant difference was the contracted index proximal interphalangeal joint (p=0.0347). Preferences did affect the standard deviations and ranges but not the means of the measurements. Interrater reliability was high (ICC 2,1: 0.99 and 0.86). Clinical and radiographic measurements were markedly different from each other (paired-difference t-tests), leading to inconclusive concurrent validity.
这项重复测量单病例设计研究的目的是描述测角器放置偏好及其对近端和远端指间关节测量的影响，确定评分者间信度，并确定同时效度。39名治疗师使用德沃尔测角器和6英寸透明测角器对一名患者进行了背侧和外侧测量。研究中使用的两种测角器之间未发现显著差异。外侧和背侧测量均值的比较显示，唯一存在显著差异的关节是收缩的示指近端指间关节（p = 0.0347）。偏好确实影响了测量的标准差和范围，但不影响测量均值。评分者间信度较高（组内相关系数ICC 2,1：0.99和0.86）。临床测量和影像学测量彼此明显不同（配对差异t检验），导致同时效度不确定。
