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（根据申请人的摘要改编）：此项目交易 严重患者的下肢功能恢复下肢功能的问题 需要使用标准的脚踝或后足的关节炎 脚踝矫形器（AFO）或后足矫形器（表达，非 - 铰接）并锁定脚踝或后足，以保持稳定性 步态。这些患者具有僵硬的关节，痛苦，并且 损害他们走路的能力。目前，这些类型的患者是 安装了常规的刚性聚丙烯AFO，以限制运动。 这些设备限制了脚踝，后足和中足运动 步行。这可能会导致步态效率低下，不必要地固定 不受影响的关节，衰弱的患者可能无法容忍 由于它们的体重或双侧障碍。目标的目标 项目将测试两个轻巧的后足矫形器（铰接和 在正常和关节炎中的未明显）和标准AFO 三个不同的步行环境。 在水平，侧斜率和坡道行走中，他们建议：1）执行 正常的三个矫形器的步态模式的客观测量 受试者； 2）测试这三个矫形器的性能 患有踝关节或下关节炎的患者。这些研究的结果 预计会提高步态对关节炎患者的疗效 谁需要常规的AFO治疗。除了患者 关节炎，这些矫形器将对踝关节患者有用 不稳定性，室内不稳定性和神经肌肉疾病。
