An improved powered ankle-foot orthosis using proportional myoelectric control.
TL;DR: The current design improves upon a previous prototype by being easier to don and doff and simpler to use and the novel controller allows naive wearers to quickly adapt to the orthosis without artificial muscle co-contraction.

Metabolic and mechanical energy costs of reducing vertical center of mass movement during gait.
TL;DR: Reducing vertical COM movement is not a successful strategy for improving either metabolic or mechanical energy economy during normal walking by able-bodied subjects because of greater mechanical work performed at the hip, knee, and ankle joints.

TL;DR: Several computational models of slacking are reviewed, and implications ofSlacking for the design of robotic orthoses are discussed, which may reduce human effort during rehabilitation training, with negative consequences for use-dependent motor recovery.

Preswing Knee Flexion Assistance Is Coupled With Hip Abduction in People With Stiff-Knee Gait After Stroke
James Sulzer,Keith E. Gordon,Yasin Y. Dhaher,Michael A. Peshkin,James L. Patton,James L. Patton +5 more
TL;DR: Hip abduction increased when stroke subjects received assistive knee flexion torque at foot-off, in direct contrast to the traditional belief that pelvic obliquity combined with hip abduction is a compensatory mechanism to facilitate foot clearance during swing.

TL;DR: A body weight support system that monitors and controls the level of support force within a stepcycle to result in normative center of mass movement and ground reaction forces is described in this paper.
