3D多节段足部模型(3DMFM)的重复性研究主要考虑了健康受试者，这与这些模型广泛应用于足部病理评估形成了鲜明对比。本研究旨在建立Leardini等人描述的3DMFM的可重复性。[3]在存在足部畸形的情况下，采用重复测量设计分析了8名成年参与者的足部运动学，其中包括两名具有不同经验水平的治疗师。与健康受试者的运动学相比，试验间变异性更高。考虑到相对角度，会间变异性最小。沙卡尔和卡尔-梅特之间的绝对3D旋转似乎在两位治疗师中具有最低的变异性。目前的研究表明，不仅可以一致地测量患者的相对三维旋转和平面角度，而且可以一致地测量一些绝对参数作为决策过程的基础。(C)2012爱思唯尔B.V.保留所有权利。
Repeatability studies on 3D multi-segment foot models (3DMFMs) have mainly considered healthy participants which contrasts with the widespread application of these models to evaluate foot pathologies. The current study aimed at establishing the repeatability of the 3DMFM described by Leardini et al. [3] in presence of foot deformities.Foot kinematics of eight adult participants were analyzed using a repeated-measures design including two therapists with different levels of experience.The inter-trial variability was higher compared to the kinematics of healthy subjects. Consideration of relative angles resulted in the lowest inter-session variability. The absolute 3D rotations between the Sha-Cal and Cal-Met seem to have the lowest variability in both therapists. A general trend towards higher sigma(sess)/sigma(trial) ratios was observed when the midfoot was involved.The current study indicates that not only relative 3D rotations and planar angles can be measured consistently in patients, also a number of absolute parameters can be consistently measured serving as basis for the decision making process.
