DESCRIPTION (provided by applicant): A vast number of people are affected by conditions that result in profound muscle weakness or impaired motor control that impede the ability to walk. If motor function is completely lost, rehabilitation of walking function may be delayed until the patient is able move actively. Delayed therapy often leads to secondary impairments that exacerbate a patient's functional losses such as disuse atrophy and general deconditioning. Currently, therapists can begin rehabilitation of walking by using lower extremity braces or body weight supported treadmill training to support the weak limb. No currently available lower extremity braces can provide the patient the experience of typical movement patterns; rather braces are designed to immobilze the limb on which the patient bears weight. This fosters abnormal, inefficient and very energy costly movement patterns that might be difficult to overcome. During body weight supported treadmill training the body is suspended over a treadmill and all or part of the body weight is eliminated. Typical walking patterns are simulated by a manual positioning of the limb by therapists, a very time intensive and costly form of rehabilitation. The proposed project involves the development of a Smart Knee Brace (SKB) for use in rehabilitation of walking in persons with lower extremity weakness. The purpose of this study is to develop the SKB that will help to control knee movement during the stance phase of gait by encouraging more normal movement patterns while allowing free knee motion during the swing phase, something no commercially available braces can do. The SKB will provide control of the knee joint that will be adjusted for each patient based on his or her walking ability and the goals of their rehabilitation. This proposal represented the first phase of the work to develop the SBK and its electronic controllers based on walking patterns from healthy older subjects. Feasibility of the SKB will also be tested on healthy subjects and 3atients with hemiparesis from stroke. The data collected during the proposed work will be used to plan Future clinical phases of the work.

描述（由申请人提供）：大量人受到导致肌肉无力或阻碍行走能力的运动控制受损的条件的影响。如果运动功能完全丢失，则步行功能的康复可能会延迟，直到患者能够积极移动为止。延迟的治疗通常会导致继发性障碍加剧患者的功能损失，例如废除萎缩和一般性化处理。目前，治疗师可以通过使用下肢牙套或体重支持跑步机训练来支撑弱肢体来开始康复。目前没有可用的下肢括号可以为患者提供典型运动模式的体验；相反的牙套旨在使患者承受重量的肢体固定。这促进了可能难以克服的异常，效率低下且能源昂贵的运动模式。在体重支撑跑步机训练期间，身体在跑步机上悬挂，并消除了体重的全部或部分体重。典型的步行模式是通过治疗师对肢体的手动定位进行模拟的，这是一种非常耗时且昂贵的康复形式。拟议的项目涉及开发智能膝盖支架（SKB），用于用于恢复下肢弱点的人行走。这项研究的目的是开发SKB，这将通过鼓励更正常的运动模式，同时允许在挥杆阶段进行自由膝盖运动，从而有助于控制膝盖的运动，这是在挥杆阶段允许自由的膝盖运动，这是不可商售的支撑。 SKB将根据他或她的步行能力和康复目标对膝关节的控制进行控制。该提案代表了基于健康较老受试者的步行模式开发SBK及其电子控制器的工作的第一阶段。 SKB的可行性还将在健康受试者和三种卒中偏瘫的能力上进行测试。在拟议的工作期间收集的数据将用于计划工作的未来临床阶段。
