Hand Control With Invasive Feedback Is Not Impaired by Increased Cognitive Load

Silvestro Micera, Francesco Maria Petrini, Ivo Strauss, Giacomo Valle, Edoardo D'Anna

Recent experiments have shown that neural stimulation can successfully restore sensory feedback in upper-limb amputees improving their ability to control the prosthesis. However, the potential advantages of invasive sensory feedback with respect to non-inv ...

A biomimetic electrical stimulation strategy to induce asynchronous stochastic neural activity

Silvestro Micera, Stéphanie Lacour, Edoardo D'Anna, Emanuele Formento, Sandra Gribi

Objective.Electrical stimulation is an effective method for artificially modulating the activity of the nervous system. However, current stimulation paradigms fail to reproduce the stochastic and asynchronous properties of natural neural activity. Here, we ...

Sensitivity to temporal parameters of intraneural tactile sensory feedback

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

Background Recent studies have shown that neural stimulation can be used to provide artificial sensory feedback to amputees eliciting sensations referred on the amputated hand. The temporal properties of the neural stimulation modulate aspects of evoked se ...

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. ...

Brain reactions to the use of sensorized hand prosthesis in amputees

Silvestro Micera, Stanisa Raspopovic, Francesco Maria Petrini, Ivo Strauss, Giacomo Valle, Fabrizio Vecchio, Francesco Iberite, Edoardo D'Anna

Objective We investigated for the first time the presence of chronic changes in the functional organization of sensorimotor brain areas induced by prolonged training with a bidirectional hand prosthesis. Methods A multimodal neurophysiological and neuroima ...

Six-Month Assessment of a Hand Prosthesis with Intraneural Tactile Feedback

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

Objective Hand amputation is a highly disabling event, which significantly affects quality of life. An effective hand replacement can be achieved if the user, in addition to motor functions, is provided with the sensations that are naturally perceived whil ...

A closed-loop hand prosthesis with simultaneous intraneural tactile and position feedback

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

Current myoelectric prostheses allow transradial amputees to regain voluntary motor control of their artificial limb by exploiting residual muscle function in the forearm. However, the overreliance on visual cues resulting from a lack of sensory feedback i ...

Although peripheral nerve stimulation using intraneural electrodes has been shown to be an effective and reliable solution to restore sensory feedback after hand loss, there have been no reports on the characterization of multi-channel stimulation. A deepe ...

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 ...

NATURE PUBLISHING GROUP2018

Upper limb amputation disrupts most daily activities and reduces the quality of life of affected individuals. Building a suitable prosthetic limb, which can restore at least some of the lost capabilities, is a goal which has been pursued for centuries. In ...
