Human-prosthesis cooperation: combining adaptive prosthesis control with visual feedback guided gait

Journal of NeuroEngineering and Rehabilitation, 2022
Background Personalizing prosthesis control is often structured as human-in-the-loop optimization. However, gait performance is influenced by both human control and intelligent prosthesis control.

Thalamic Visual Prosthesis

IEEE Transactions on Biomedical Engineering, 2016
Glaucoma is a neurological disorder leading to blindness initially through the loss of retinal ganglion cells, followed by loss of neurons higher in the visual system. Some work has been undertaken to develop prostheses for glaucoma patients targeting tissues along the visual pathway, including the lateral geniculate nucleus (LGN) of the thalamus, but ...

Visual cortical prosthesis: an electrical perspective [PDF]

Journal of Medical Engineering & Technology, 2020
The electrical stimulation of the visual cortices has the potential to restore vision to blind individuals. Until now, the results of visual cortical prosthetics has been limited as no prosthesis has restored a full working vision but the field has shown a renewed interest these last years thanks to wireless and technological advances. However, several

Effects of extended powered knee prosthesis stance time via visual feedback on gait symmetry of individuals with unilateral amputation: a preliminary study

Journal of NeuroEngineering and Rehabilitation, 2019
Background Establishing gait symmetry is a major aim of amputee rehabilitation and may be more attainable with powered prostheses. Though, based on previous work, we postulate that users transfer a previously-learned motor pattern across devices ...
