Foot dysfunction is one of the most likely consequences of rheumatoid arthritis and stroke. It is characterized by severe changes in the gait pattern due to a significant increase in the plantar flexion. Some of these dysfunctions can be compensated by using an ankle-foot orthosis. However, the clinical decision about which orthosis best suits the patient creates a real problem for physicians/therapists. The main goal of this paper is to present a quantitative support tool that can assist the physicians/therapists in deciding which orthosis is most suitable for each subject. In order to achieve such goal, a platform named OrthoRehab was developed, and it was tested in three conditions: without any orthosis and with two different ankle-foot orthoses. The data were acquired in the Gait Laboratory of Rehabilitation Medicine Center of Alcoitão using a VICON NEXUS 1.8.5 motion capture system that allows the capturing of kinematic and kinetic data. The results reveal that OrthoRehab is a user-friendly, easy to apply tool that analyzes very relevant data for the clinical staff. The developed decision support tool, OrthoRehab, offers a quantitative analysis and provides insight to which orthosis achieves the best performance in comparison with the patient's gait pattern with no orthosis.
足部功能障碍是类风湿性关节炎和中风最可能产生的后果之一。其特征是由于跖屈显著增加而导致步态模式发生严重变化。其中一些功能障碍可以通过使用踝足矫形器来代偿。然而，临床上面临的一个实际问题是，医生/治疗师很难决定哪种矫形器最适合患者。本文的主要目的是提出一种定量支持工具，以协助医生/治疗师决定哪种矫形器最适合每个患者。为实现这一目标，开发了一个名为OrthoRehab的平台，并在三种情况下进行了测试：不使用任何矫形器以及使用两种不同的踝足矫形器。数据是在阿尔科伊唐康复医学中心的步态实验室使用VICON NEXUS 1.8.5运动捕捉系统采集的，该系统能够采集运动学和动力学数据。结果表明，OrthoRehab是一个用户友好、易于应用的工具，能够为临床人员分析非常相关的数据。所开发的决策支持工具OrthoRehab提供了定量分析，并能洞察与患者不使用矫形器时的步态模式相比，哪种矫形器能实现最佳性能。
