FOOT AND ANKLE BIOMECHANICS WITH ORTHOSIS AMBULATION

描述(改编自申请者摘要)：本项目涉及 重症高血压患者的肢体功能恢复问题 脚踝或后足关节炎需要使用标准 踝足矫形器(AFO)或后足矫形器(关节，非 关节)，并锁定脚踝或后脚以保持稳定 步态。这些患者关节僵硬，关节炎，疼痛和 会削弱他们的行走能力。目前，这些类型的患者是 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。 走路。这可能会产生低效的步态，不必要的静止 未受影响的关节，虚弱的患者可能无法忍受 因为他们的体重或双侧损伤。这样做的目的是 项目是测试两个轻型后脚矫形器(关节和 和一个标准的AFO在正常和关节炎受试者中 三种不同的行走环境。 在水平、斜坡和坡道行走中，他们建议：1)执行 正常人三种矫形器步态的客观测量 受试者；以及2)测试这三种矫形器在 有脚踝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疗效 他们需要传统的AFO治疗。除了患有癌症的患者 关节炎，这些矫形器将对脚踝患者有用 不稳定、距下不稳定和神经肌肉疾病。

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.
