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 ...

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 ...

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

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

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 ...

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

Olaf Blanke, Wietske Van der Zwaag, Andrea Serino, Giulio Rognini, Roy Salomon, 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 ...

Decoding bipedal locomotion from the rat sensorimotor cortex

Silvestro Micera, Grégoire Courtine, Jacopo Rigosa, Lucia Florinda Friedli Wittler

Objective. Decoding forelimb movements from the firing activity of cortical neurons has been interfaced with robotic and prosthetic systems to replace lost upper limb functions in humans. Despite the potential of this approach to improve locomotion and fac ...

Facial rehabilitative device based on robogami (robotic origami) platform

Jamie Paik, Amir Firouzeh

The present invention relates to a facial rehabilitative device based on Robogami (Robotic Origami) platform. The device facilitates the process of the physical therapy for the therapist, to make this process more disciplined, and to enhance the result for ...

Instrumented Knee Prosthesis for Force and Kinematics Measurements

Philippe Renaud, Kamiar Aminian, Catherine Dehollain, Pierre-André Farine, Arnaud Bertsch, Peter Ryser, Brigitte Jolles-Haeberli, Arash Arami, Eric Meurville, Steve Tanner, Oguz Atasoy, Shafqat Ali, Matteo Simoncini, Willyan Hasenkamp Carreira

In this work, we present the general concept of an instrumented smart knee prosthesis for in-vivo measurement of forces and kinematics. This system can be used for early monitoring of the patient after implantation and prevent possible damage to the prosth ...

Tribo-electrochemical characterization of metallic biomaterials for total joint replacement

Stefano Mischler

Knee and hip joint replacement implants involve a sliding contact between the femoral component and the tibial or acetabular component immersed in body fluids, thus making the metallic parts susceptible to tribocorrosion. Micro-motions occur at points of f ...

Starch-induced implant periapical lesion: A case report

This paper reports an implant periapical lesion (IPL) with a previously unreported etiology. The presence of an osteolytic area around the apex and around the middle portion of a stable Straumann hollow-screw implant was found on periapical radiographs 3.5 ...
