IEEE Trans Neural Syst Rehabil Eng
. 2015 Apr;
24(4):455-66.
PMID: 25915961
This paper describes a hybrid system that combines a powered lower limb exoskeleton with functional electrical stimulation (FES) for gait restoration in persons with paraplegia. The general control structure consists...

Murray S, Ha K, Goldfarb M
Annu Int Conf IEEE Eng Med Biol Soc
. 2015 Jan;
2014:4083-6.
PMID: 25570889
This paper describes a novel controller, intended for use in a lower-limb exoskeleton, to aid gait rehabilitation in patients with hemiparesis after stroke. The controller makes use of gravity compensation,...

Murray S, Ha K, Hartigan C, Goldfarb M
IEEE Trans Neural Syst Rehabil Eng
. 2014 Aug;
23(3):441-9.
PMID: 25134084
This paper presents a control approach for a lower-limb exoskeleton intended to facilitate recovery of walking in individuals with lower-extremity hemiparesis after stroke. The authors hypothesize that such recovery is...
