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.

Ultrasound stimulation for non-invasive visual prostheses

Frontiers in Cellular Neuroscience, 2022
Globally, it is estimated there are more than 2.2 billion visually impaired people. Visual diseases such as retinitis pigmentosa, age-related macular degeneration, glaucoma, and optic neuritis can cause irreversible profound vision loss. Many groups have

Visual Prosthesis: Artificial Vision [PDF]

Medical Journal Armed Forces India, 2009
In the normal visual pathway, light travels through the tear film, cornea, aqueous, pupil, lens, and vitreous, to activate the light sensitive photoreceptors and set up the trans-synaptic connections of the retina (Fig. 1). In cases where there is gross destruction of the eye like phthisis bulbi, restoration of vision is not possible. But in conditions

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

Inducing lateralized phosphenes over the occipital lobe using transcranial magnetic stimulation to navigate a virtual environment.

PLoS ONE, 2021
Electrical stimulation involving visual areas of the brain produces artificial light percepts called phosphenes. These visual percepts have been extensively investigated in previous studies involving intracortical microsimulation (ICMS) and serve as the ...

Action and non-action oriented body representations. insight from behavioural and grey matter modifications in individuals with lower limb amputation [PDF]

, 2018
Following current model of body representations, we aimed to systematically investigate the association between brain modifications, in terms of grey matter loss, and body representation deficits, in terms of alterations of the body schema (BS) and of ...

Osseointegrated prostheses for rehabilitation following amputation : The pioneering Swedish model. [PDF]

, 2017
The direct attachment of osseointegrated (OI) prostheses to the skeleton avoids the inherent problems of socket suspension. It also provides physiological weight bearing, improved range of motion in the proximal joint, as well as osseoperceptive sensory ...
