A high degree of intra - and inter - rater reproducibility was obtained in measurement of a standardized area of the head of the first right metacarpal using a precision digitizer. This instrument had an accuracy for every point digitized of 0.127 mm. Intra-rater difference between readings at approximately a month's interval showed no significant differences. The method is reasonably simple to perform and is applicable to small joints such as the proximal interphalangeal joints. The method may prove useful in following progression of joint damage in rheumatoid arthritis.
使用精密数字化仪测量右手第一掌骨头的标准化区域时，在测量者内部和测量者之间均获得了高度的可重复性。该仪器对每个数字化点的精度为0.127毫米。大约一个月间隔的测量者内部读数差异无显著差异。该方法操作相当简单，适用于近端指间关节等小关节。该方法可能在追踪类风湿关节炎关节损伤进展方面证明有用。
