Event-related causality in stereo-EEG discriminates syntactic processing of noun phrases and verb phrases

Objective. Syntax involves complex neurobiological mechanisms, which are difficult to disentangle for multiple reasons. Using a protocol able to separate syntactic information from sound information we investigated the neural causal connections evoked by t ...

Prosthetic Control and Sensory Feedback for Upper Limb Amputees

Huaiqi Huang

Hand amputation could dramatically degrade the life quality of amputees. Many amputees use prostheses to restore part of the hand functions. Myoelectric prosthesis provides the most dexterous control. However, they are facing high rejection rate. One of th ...

Fixed and mobile-bearing total ankle prostheses: Effect on tibial bone strain

Alexandre Terrier, Xavier Crevoisier, Caroline Sieger Fernandes, Maïka Réane Guillemin

Background Total ankle replacement is associated to a high revision rate. To improve implant survival, the potential advantage of prostheses with fixed bearing compared to mobile bearing is unclear. The objective of this study was to test the hypothesis th ...

Fascicular nerve stimulation and recording using a novel double-aisle regenerative electrode

Silvestro Micera

Objective. As artificial prostheses become more refined, they are most often used as a therapeutic option for hand amputation. By contrast to extra- or intraneural interfaces, regenerative nerve electrodes are designed to enable electrical interfaces with ...

Upper limb cortical maps in amputees with targeted muscle and sensory reinnervation

Olaf Blanke, Andrea Serino, Wietske Van der Zwaag, Roy Salomon, Giulio Rognini, Roberto Martuzzi, Elisa Canzoneri, Michel Akselrod, Maria Laura Blefari

Neuroprosthetics research in amputee patients aims at developing new prostheses that move and feel like real limbs. Targeted muscle and sensory reinnervation (TMSR) is such an approach and consists of rerouting motor and sensory nerves from the residual li ...

Computational comparison of aortic root stresses in presence of stentless and stented aortic valve bio-prostheses

Alfio Quarteroni, Christian Vergara, Elena Faggiano

We provide a computational comparison of the performance of stentless and stented aortic prostheses, in terms of aortic root displacements and internal stresses. To this aim, we consider three real patients; for each of them, we draw the two prostheses con ...

In-situ photopolymerized and monitored implants: successful application to an intervertebral disc replacement

Dominique Pioletti, Christophe Moser, Andreas Schmocker, Azadeh Khoushabi

Photopolymerization is a common method to harden materials initially in a liquid state. A surgeon can directly trigger the solidification of a dental implant or a bone or tissue filler by using ultra-violet light. Traditionally, photopolymerization has bee ...

Restoring Natural Sensory Feedback in Real-Time Bidirectional Hand Prostheses

Silvestro Micera, Marco Capogrosso, Stanisa Raspopovic, Francesco Maria Petrini, Jacopo Rigosa, Marco Bonizzato

Hand loss is a highly disabling event that markedly affects the quality of life. To achieve a close to natural replacement for the lost hand, the user should be provided with the rich sensations that we naturally perceive when grasping or manipulating an o ...

Design and integration of an instrumented knee prosthesis

Matteo Simoncini

Total knee arthroplasty is nowadays one of the most important orthopedic surgery. It consists of a procedure in which parts of the knee are replaced by a prosthesis. The largest indication for total knee arthroplasty is osteoarthritis, a knee disease that ...
