本文研究了在执行运动和体育锻炼时重建下肢骨骼在空间中的位置和方向的实验问题。分析与标记物和下面的骨骼之间的相对运动相关的误差。通过对患有骨折并佩戴股骨或胫骨外固定器的受试者进行实验来收集有关此运动的定量信息。后面的这些装置提供了与所涉及的骨骼可靠刚性的框架，因此可以评估安装在皮肤上的标记与该骨骼之间的相对运动。使用基于不同皮肤标记簇及其相对于评估的相关骨骼的旋转的技术框架来重建与大腿和小腿相关的解剖框架。还使用数字视频荧光检查对具有完整肌肉骨骼结构的受试者的标记运动进行了评估。
This paper deals with the experimental problems related to the reconstruction of the position and orientation of the lower limb bones in space during the execution of locomotion and physical exercises. The inaccuracies associated with the relative movement between markers and underlying bone are analysed. Quantitative information regarding this movement was collected by making experiments on subjects who had suffered fractures and were wearing either femoral or tibial external fixators. These latter devices provided frames that were reliably rigid with the bone involved, and hence the possibility of assessing the relative movement between markers mounted on the skin and this bone, Anatomical frames associated with thigh and shank were reconstructed using technical frames based on different clusters of skin markers and their rotation with respect to the relevant bone evaluated. Marker movement was also assessed in subjects with intact musculoskeletal structures using digital videofluoroscopy.
