A 2-axis goniometer has been developed which accommodates the metacarpophalangeal (MCP) changes of rheumatoid arthritis and permits accurate measurement of laxity of the MCP joints. Measurements made with the instrument on 51 subjects with definite or classical rheumatoid arthritis showed high percentages of intrarater and interrater agreement for repeated trials. These results suggest that, following the methods outlined, the 2-axis goniometer can be used to obtain reliable objective measurements of MCP lateral mobility by 1 or more raters with a minimum of training.
已经开发出一种双轴测角仪，它能够适应类风湿性关节炎患者掌指关节（MCP）的变化，并能精确测量MCP关节的松弛度。用该仪器对51名确诊或典型类风湿性关节炎患者进行测量，结果显示，在重复试验中，评分者内和评分者间的一致性百分比很高。这些结果表明，按照所述方法，双轴测角仪可由1名或多名评分者在最少培训的情况下用于获得MCP侧向活动度的可靠客观测量值。
