The object of the work proposed is to develop an advanced controlled- impedance spring/damping device for an above knee prosthesis which can be controlled by the amputee wearing the limb or, eventually by automatic adjustments to parameters like gait speed and load on the leg. By utilizing recent advances in small robotic actuators and sensors, a practical device is now possible which interfaces with present knee/shin set ups, to implement both automatic and user-controlled variations in the knee impedance for an above knee prosthesis. This will above knee amputees much more direct control over the knee joint. Walking and running may be more smooth and stable and the amputee will be able to adapt easier to variations in cadence and activity, e.g., up hill or down hill walking and sports activities. Such a system (i.e., easily programmable and adjustable) could also function as an evaluation tool during the prosthesis fitting stage, for determining certain pre- programmed settings in a simpler, less expensive knee joint installed in the finished limb.

本文提出的工作目标是开发一种先进的可控、可控、可控的自动控制系统。 用于膝上假体的阻抗弹簧/阻尼器，其可以 由佩戴肢体的截肢者控制，或最终由自动 调整步态速度和腿部负荷等参数。通过 利用小型机器人执行器和传感器的最新进展， 与现有膝盖/胫骨接口的实用设备现已成为可能 设置，在中实现自动和用户控制的变体 膝上假体的膝关节阻抗。这将超过膝盖。 截肢者对膝关节的控制要直接得多。步行和 跑步可能会更流畅和稳定，截肢者将能够 更容易适应节奏和活动的变化，例如上坡或下坡 爬山和体育活动。这样的系统(即，容易 可编程和可调整)也可用作评估工具 在假体装配阶段，用于确定某些预 更简单、更便宜的膝关节中的编程设置安装在 完成的肢体。
