Abstract

The paper deals with the mechanical design of a new active stance-control knee-ankle-foot orthosis (SCKAFO). The orthosis is intended to provide gait assistance for incomplete spinal cord injured patients that present functional hip muscles, but partially denervated knee and ankle muscles. It consists of a passive compliant joint that constrains ankle plantar flexion, along with a powered knee unit that prevents knee flexion during stance and controls flexion-extension during swing. For this purpose, the knee joint incorporates a controllable mechanical locking system and an electrical DC motor that actuate independently. The prototype is equipped with different sensors (plantar sensors and angular encoders) for control purposes. They are used to identify the main events defining the gait phases and to provide feedback measurements for the motor control system.

一种用于不完全性脊髓损伤患者步态辅助的动力下肢矫形器

本文研究了一种新型主动姿态控制膝-踝-足矫形器的机械设计。矫形器的目的是为不完全性脊髓损伤患者提供步态辅助，这些患者的髋关节肌肉功能正常，但膝关节和踝关节肌肉部分失神经。它由一个被动的关节组成，可以限制踝关节的足底屈曲，同时还有一个动力膝盖单元，可以防止站立时膝盖屈曲，并控制摆动时的屈伸。为此，膝关节结合了一个可控的机械锁定系统和一个独立驱动的直流电机。原型配备了不同的传感器(足底传感器和角度编码器)用于控制目的。它们被用来识别定义步态阶段的主要事件，并为运动控制系统提供反馈测量。
