由于电动测角法已被证明可用于测量下肢关节运动，因此也开发了一种用于测量肘关节和前臂旋转的类似装置。在本设计中，前臂旋转轴与解剖轴重合，消除了常规三轴测角仪中存在的串扰。尽管外展内收轴仍然偏离肘关节，但为了获得等效运动，采用了特殊的连杆布置。用实验方法验证了装置的准确性，并进行了模型模拟，强调了仪器准确放置在受试者身上的重要性。通过对正常受试者肘关节活动范围的研究，阐明了进行日常生活活动所需的肘关节活动范围。该设备目前用于肘部和前臂问题患者的功能评估。
Since the electrogoniometric method has been justified for the measurement of lower extremity joint motion, a similar device is developed for the measurement of elbow joint and forearm rotations. In this design, the axis of forearm rotation coincides with the anatomical axis which eliminates the cross talk existing in the regular triaxial goniometer. Although the axis of abduction-adduction is still offset from the elbow joint, special linkage arrangement was used to obtain equivalent motion. Experimental method was used to validate the accuracy of the device and model simulation was performed to emphasize the importance of accurate placement of the instrument on test subjects. Application of the present apparatus to normal subjects was studied to illustrate the range of elbow motion required in performing normal activities of daily living. This device is currently used in the functional evaluation of patients with elbow and forearm problems.
