客观的。描述用于获取肩部运动学数据的记录和处理方法，该方法除了通常的精度和准确度要求外还满足三个标准：足够的速度、获得完整的 3D 运动学（包括关节旋转）以及基于参考点的坐标系的使用。设计。基于使用六自由度电磁跟踪装置的触诊技术，在标准化肱骨抬高过程中静态记录肩骨方向。背景。基础肌肉骨骼和临床研究迫切需要一种简单、快速、标准化的测量方法来获取完整的 3D 肩部运动学数据。设计并开发了一种测量方法。肩部运动学由两名观察者对 15 名健康受试者进行重复测量而获得。建立了试验间、日间、观察者间和受试者间的变异性。结果与文献进行比较。结果。获得了完整的运动学描述。可以达到大约每秒一个位置的测量速度。发现测量的运动学和测量精度与文献一致。结论。先前制定的用于获得肩部运动学的临床有用方法的所有标准均已满足。
Objective. To describe a recording and processing methodology for obtaining kinematic data of the shoulder which meets three more criteria besides usual requirements regarding precision and accuracy: sufficient speed, obtaining complete 3D kinematics including joint rotations, and usage of coordinate systems based on reference points.Design. Static recordings of shoulder bone orientations during standardized humerus elevations based on the palpation technique using a six-degree-of-freedom electromagnetic tracking device.Background. An easy, fast, well standardized measurement methodology for obtaining complete 3D shoulder kinematic data is urgently needed for fundamental musculoskeletal and clinical research.Methods. A measurement methodology was designed and developed. Shoulder kinematics were obtained from repeated measurements on 15 healthy subjects performed by two observers. Inter-trial, inter-day, inter-observer and inter-subject variability were established. Results were compared to literature.Results. Complete kinematic descriptions were obtained. A measurement speed of about one position per second could be reached. The measured kinematics and accuracy of the measurements were found to be in concordance with the literature.Conclusion. All previously formulated criteria for a clinical useful method for obtaining shoulder kinematics have been met.
