Bionic Leg Prosthesis Emulates Biological Ankle Joint during Walking
Figure 1. The bionic prosthesis’ mass of 2.0 kg is equivalent to a biological foot and partial shank of an 80 kg person. The prosthesis includes a carbonfiber in-series leaf spring, unidirectional parallel leaf spring, and heel and forefoot leaf springs that provide elasticity. A series-elastic actuator performs negative and positive work. The actuator is comprised of a 200-Watt DC brushless mo...
متن کاملEvaluation of a Viscoelastic Ankle-Foot Prosthesis at Slow and Normal Walking Speeds on an Able-Bodied Subject
Objectives: This paper describes further improvement and preliminarily evaluation of a novel viscoelastic ankle-foot prosthesis prototype. The objective was to control the ankle hysteresis at slow and normal walking speeds. Methods: Inspired by the ankle biomechanics, in which the hysteresis differs based on the gait speeds, a manually damping control mechanism imbedded in the prosthesis for...

متن کاملExamination of knee joint moments on the function of knee-ankle-foot orthoses during walking.
The goal of this study was to investigate clinically relevant biomechanical conditions relating to the setup and alignment of knee-ankle-foot orthoses and the influence of these conditions on knee extension moments and orthotic stance control during gait. Knee moments were collected using an instrumented gait laboratory and concurrently a load transducer embedded at the knee-ankle-foot orthosis...
متن کاملEffect of push-off timing on metabolic cost during walking with a universal ankle-foot prosthesis emulator
1 Introduction The ankle delivers about half of the total mechanical work during walking. Lower-limb amputees using conventional passive-elastic prostheses experience 20 to 30% higher metabolic cost than able-bodied individuals, perhaps because these prostheses do not provide net positive work during the course of a step [1]. To address this problem, companies are developing battery-powered pro...
