Design and Control of a Lower Limb Exoskeleton for Robot‐Assisted Gait Training

Applied Bionics and Biomechanics, Volume 6, Issue 2, Page 229-243, 2009., 2009
Robot‐assisted rehabilitation of gait still faces many challenges, one of which is improving physical human‐robot interaction. The use of pleated pneumatic artificial muscles to power a step rehabilitation robot has the potential to meet this challenge. This paper reports on the development of a gait rehabilitation exoskeleton with a knee joint powered

Passive-elastic knee-ankle exoskeleton reduces the metabolic cost of walking

Journal of NeuroEngineering and Rehabilitation, 2020
Background Previous studies have shown that passive-elastic exoskeletons with springs in parallel with the ankle can reduce the metabolic cost of walking. We developed and tested the use of an unpowered passive-elastic exoskeleton for walking that stores
