Assessment of the Functional Impact of a Close-loop Controlled Prehension Neuroprosthesis in Post-stroke Patients

"The experimental condition corresponds to patients in the condition where the prehension neuroprosthesis is active, which means that the extensor muscles of the fingers and thumb will be stimulated by the prehension neuroprosthesis to ensure the opening of the hand. The prehension neuroprosthesis designates a functional electrical stimulation device controlled by the patient which will itself trigger the stimulation of the extensor muscles of the fingers (closed-loop control), according to stimuli which it controls voluntarily. The goal is to restore an opening of the fingers to capture objects.~The control condition corresponds to the patients in the condition where the prehension neuroprosthesis is inactive."
