Cortical plasticity after hand prostheses use: Is the hypothesis of deafferented cortex "invasion" always true?

Silvestro Micera, Stanisa Raspopovic, Francesco Maria Petrini, Edoardo D'Anna, Ivo Strauss, Pablo Garcia del Valle, Giacomo Valle, Francesco Iberite

Objective: To study motor cortex plasticity after a period of training with a new prototype of bidirectional hand prosthesis in three left trans-radial amputees, correlating these changes with the modification of Phantom Limb Pain (PLP) in the same period. ...

Comparison of linear frequency and amplitude modulation for intraneural sensory feedback in bidirectional hand prostheses

Silvestro Micera, Stanisa Raspopovic, Francesco Maria Petrini, Edoardo D'Anna, Ivo Strauss, Pablo Garcia del Valle, Giacomo Valle, Francesco Iberite

Recent studies have shown that direct nerve stimulation can be used to provide sensory feedback to hand amputees. The intensity of the elicited sensations can be modulated using the amplitude or frequency of the injected stimuli. However, a comprehensive c ...
