基于陀螺原理设计了改进型三轴测角仪。该装置能够测量对应于一组特定欧拉角的关节三维角运动。由于该装置的角度测量不依赖于序列，因此便于提供关节从一个位置到另一个位置的独特运动模式。关节旋转轴基于可识别的骨标志进行定向，这提供了所涉及的解剖运动的方便可视化。由仪器外骨骼附着引起的误差在理论上是可以修正的。综合考虑人体关节功能评价中的各种因素，三轴测角仪是一种简便、真实的实时、三维角运动测量的有效方法。
The modified triaxial goniometer was designed based on the gyroscopic concept. This device is capable of measuring the joint 3-dimensional angular motion corresponding to a specific set of Eulerian angles. Since the angular measurement by this device is not sequence dependent, it is convenient to provide unique motion patterns of the joint from one position to another. The joint rotational axes are oriented based on identifiable bony landmarks which provide a convenient visualization of the anatomical motion involved. The error caused by the exoskeletal attachment of the instrument can be theoretically corrected. Considering all factors in human joint functional evaluation, the triaxial goniometer is a useful and effective method to provide simple, real time, 3-dimensional angular motion measurements.
