BACKGROUND
No goniometric technique is both maximally convenient and completely accurate, although photogoniometry (ie, picture taking to facilitate digital angle measurement) shows promise in this regard. Our purpose was to test the feasibility and reliability of a photogoniometric protocol designed to measure wrist and digit range of motion in general.
METHODS
Two independent observers examined a sample of joints in both normal and abnormal hands according to a photogoniometric protocol. Interrater and intrarater correlation were calculated, and these measurements were compared with measurements made by a third independent examiner with a manual goniometer.
RESULTS
The photo-based measurements were reliable within and between observers; however, only a minority of these measurements were in agreement with manually collected values.
CONCLUSIONS
At present, photogoniometry is not an acceptable alternative to manual goniometry for determining wrist and digit range of motion in general. Joint-specific photogoniometry should be the subject of future study, as should relevant imaging and software technology.
背景
尽管摄影测角法（即拍照以方便进行数字角度测量）在这方面显示出前景，但尚无一种测角技术既极其方便又完全准确。我们的目的是测试一种旨在测量手腕和手指一般活动范围的摄影测角方案的可行性和可靠性。
方法
两名独立观察者根据摄影测角方案检查了正常和异常手部的关节样本。计算了观察者间和观察者内的相关性，并将这些测量结果与第三名独立检查者使用手动测角仪进行的测量结果进行了比较。
结果
基于照片的测量在观察者之间和内部都是可靠的；然而，这些测量结果中只有少数与手动收集的值一致。
结论
目前，对于一般情况下确定手腕和手指的活动范围，摄影测角法不是手动测角法可接受的替代方法。特定关节的摄影测角法以及相关的成像和软件技术应成为未来研究的主题。
