DESCRIPTION (Adapted from the Applicant's Abstract): This project deals with the issue of restoring lower limb function in patients with severe arthritis of the ankle or hindfoot who require the use of a standard ankle foot orthosis (AFO) or hindfoot orthosis (articulated, non- articulated) and to lock the ankle or hindfoot for stability during gait. These patients have stiff, arthritic joints which are painful and impair their ability to walk. Currently, these types of patients are fitted with a conventional rigid polypropylene AFO to limit movement. These devices restrict ankle, hindfoot, and midfoot movement during walking. This may produce inefficient gait, unnecessarily immobilize unaffected joints, and may not be tolerated by debilitated patients because of their weight or bilateral impairments. The goal of this project is to test two lightweight hindfoot orthoses (articulated and non-articulated) and a standard AFO in normal and arthritic subjects in three different walking environments. In level, side-slope, and ramp walking, they propose to: 1) perform objective measurements of gait patterns for the three orthoses in normal subjects; and 2) test the performance of these three orthoses in patients with ankle or subtalar arthritis. The results of these studies are expected to improve the efficacy of gait in patients with arthritis who require conventional AFO treatment. In addition to patients with arthritis, these orthoses will be useful for patients with ankle instability, subtalar instability, and neuromuscular disorders.

描述（改编自申请人的摘要）：该项目涉及 重症患者下肢功能恢复问题 需要使用标准的踝关节或后足关节炎 踝足矫形器 (AFO) 或后足矫形器（铰接式、非 铰接式）并锁定脚踝或后足以确保稳定性 步态。这些患者的关节僵硬、关节炎，疼痛难忍 损害他们的行走能力。目前，此类患者 配有传统的刚性聚丙烯 AFO 以限制移动。 这些装置限制脚踝、后足和中足的运动 步行。这可能会产生低效的步态，不必要的固定 不受影响的关节，虚弱的患者可能无法忍受 因为他们的体重或双侧损伤。此举的目标 项目是测试两种轻型后足矫形器（铰接式和 非关节式）和标准 AFO（正常和关节炎受试者） 三种不同的步行环境。 在水平、边坡和坡道行走中，他们建议：1）执行 正常情况下三种矫形器步态模式的客观测量 科目； 2）测试这三种矫形器的性能 患有踝关节或距下关节炎的患者。这些研究的结果 有望改善关节炎患者的步态功效 需要常规 AFO 治疗的人。除了患有以下疾病的患者 关节炎，这些矫形器对踝关节患者很有用 不稳定、距下不稳定和神经肌肉疾病。
