This is a reliability study using the intraclass correlation coefficient.
The purpose of this study was to determine whether an individual with minimal training could use the iPhone Level application to self-measure the range of motion of the forearm and wrist from a remote location.
Forty healthy participants (80 wrists) were measured twice by two examiners using a universal goniometer and the iPhone Level application. After measurement, each participant received a training session in the self-measurement method. They were then asked to perform remote self-measurements two to three days later and report their findings to the examiners using Skype or FaceTime.
SPSS, version 26, was used to run intraclass correlation coefficients using a two-way random analysis at a 95% confidence interval with absolute agreement. Comparisons of single measurements were used to determine reliability. Good inter-rater reliability was found between wrist flexion and extension in all testing conditions. Measurement of active motion in supination, pronation, radial, and ulnar deviation demonstrated moderate reliability compared with the universal goniometer where the measurements were performed by the investigators. Self-measurement of the participant resulted in moderate reliability for supination and poor reliability in pronation, radial, and ulnar deviation.
Some participants found the procedures technologically and perceptually challenging. Anatomical variances, positional requirements, and substitution patterns complicated the process.
The iPhone Level application may be used to perform reliable self-measurements of wrist flexion and extension from a remote location. Further research exploring methods for remote selfmeasurement is indicated.
这是一项使用组内相关系数的可靠性研究。
本研究旨在确定经过最少培训的个体是否可以使用 iPhone 水平仪应用程序从远程位置自行测量前臂和手腕的活动范围。
40 名健康参与者（80 个手腕）由两名检查者使用通用量角器和 iPhone 水平仪进行两次测量。测量后，每位参与者接受一次自我测量方法的培训。然后，他们被要求在两到三天后进行远程自我测量，并使用 Skype 或 FaceTime 将他们的发现报告给检查者。
使用 SPSS 版本 26，使用双向随机分析在 95%置信区间内进行组内相关系数分析，采用绝对一致性。对单次测量的比较用于确定可靠性。在所有测试条件下，腕关节屈伸的测量结果都显示出良好的检查者间可靠性。与由研究人员进行测量的通用量角器相比，在旋前、旋后、桡侧和尺侧偏斜的主动运动测量中，测量结果显示出中度可靠性。参与者的自我测量结果在旋前显示出中度可靠性，而在旋后、桡侧和尺侧偏斜的测量中可靠性较差。
一些参与者发现这些程序在技术和感知上具有挑战性。解剖变异、位置要求和替代模式使过程复杂化。
iPhone 水平仪应用程序可用于从远程位置可靠地测量腕关节屈伸。需要进一步研究探索远程自我测量的方法。
