人体运动分析仍然受到目前使用的数据收集和减少协议的弱点。可靠的数据比较和精确的功能评估需要基于解剖学的参考轴和框架的定义，因此需要仔细识别和跟踪标志。当分析受损儿童时，必须最小化标记集和其他测量程序，以减少实验时间并确保患者合作。一个新的协议，提出了骨盆和下肢运动的分析作为这两个要求之间的妥协。提出了一个标记集，其中包括22个皮肤标记的附件，由6个解剖标志的指针进行校准，并通过预测方法识别髋关节中心。根据当前建议定义解剖参考框架和关节旋转。该协议进行了评估，分析一个孩子在几个重复由不同的考官，和人口的10个健康的儿童，平均年龄9.7岁。在减去静态姿势角度的偏移后，重复整个分析。同一儿童5名检查者标准差的最小和最大均数分别为骨盆弯曲度2.1 °和膝关节旋转度6.8 °。10名健康儿童的标准差的最小和最大平均值分别为2.1度的骨盆弯曲和9.6度的膝关节内外旋转。该协议是可行的，并允许3D解剖为基础的测量段和关节运动和数据共享，根据目前的标准。(c)2007 Elsevier B.V.保留所有权利。
Human movement analysis still suffers from the weakness of the currently used protocols for data collection and reduction. Reliable data comparisons and precise functional assessment require anatomically based definitions of the reference axes and frames, and therefore careful identification and tracking of the landmarks. When impaired children are analysed, the marker-set and other measurement procedures have to be minimised to reduce the time of the experiment and ensure patient collaboration. A new protocol is proposed for the analysis of pelvis and lower limb motion obtained as a compromise between these two requirements. A marker-set is proposed which involves the attachment of 22 skin markers, the calibration by a pointer of 6 anatomical landmarks, and the identification of the hip joint centre by a prediction approach. Anatomical reference frames and joint rotations are defined according to current recommendations. The protocol was assessed by analysing a single child in several repetitions by different examiners, and a population of 10 healthy children, mean age 9.7-years-old. The entire analysis was repeated after subtraction of the offset by static posture angles. The minimum and maximum means of the standard deviations from five examiners of the same child were respectively 2.1 degrees in pelvic obliquity and 6.8 degrees in knee rotation. The minimum and maximum means of the standard deviations from the 10 healthy children were 2.1 degrees in pelvic obliquity and 9.6 degrees in knee internal-extemal rotation. The protocol is feasible and allows 3D anatomical-based measurements of segment and joint motion and data sharing according to current standards. (c) 2007 Elsevier B.V. All rights reserved.
