本研究的目的是寻找一种有效的在体测量关节运动的方法，并根据该方法给出正常膝关节的运动。选择Grood和Suntay（1983）提出的关节模型;修改胫骨起点以便于体内休息。在测量中使用了计算机化的6自由度电测角仪（EGM）。对一名受试者进行重复测试，以确定该方法的可靠性。本文对42例男性患者在水平行走时的膝关节运动进行了测量，包括膝关节的屈曲-伸展、外展-内收、外旋-内旋、内外侧平移、前后平移和上下平移。结果表明，只要选择合适的胫骨起点，EGM对外部标志的依赖性就大大降低，对关节的测量就更为有效。
The purpose of this study was to find an effective way for in vivo measurement of joint motion and give the normal knee motion according to this method. The joint model proposed by Grood and Suntay (1983) was chosen; the origin of the tibia was modified for the convenience of in vivo rest. A computerized 6 degree-of-freedom electrogoniometer (EGM) was used in the measurement. Repeated tests on one subject were performed to establish the reliability of the method. Knee motions obtained from 42 males during level walking were expressed as flexion-extension, abduction-adduction, external-internal rotation, lateral-medial translation anterior-posterior translation and superior-inferior translation The results showed that, with the proper choice of the origin of the tibia, the EGM could depend much less on external landmarks and be more effective for the joint measurement.
