A Wearable Ultrasound Interface for Prosthetic Hand Control

Xingchen Yang

Ultrasound can non-invasively detect muscle deformations and has great potential applications in prosthetic hand control. Traditional ultrasound equipment was usually too bulky to be applied in wearable scenarios. This research presented a compact ultrasou ...

Toward higher-performance bionic limbs for wider clinical use

Silvestro Micera

Most prosthetic limbs can autonomously move with dexterity, yet they are not perceived by the user as belonging to their own body. Robotic limbs can convey information about the environment with higher precision than biological limbs, but their actual perf ...

Overcorrected Implants for Total Shoulder Arthroplasty

Yasmine Boulanaache

Glenohumeral osteoarthritis is a degenerative shoulder joint disease, which causes the breakdown of articular cartilage and bone. People affected by this disease suffer from severe pain and eventually reduced mobility and poor life quality. This disease is ...

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 ...

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

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

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 ...

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 ...

Intraneural stimulation elicits discrimination of textural features by artificial fingertip in intact and amputee humans

Silvestro Micera, Fiorenzo Artoni, Stanisa Raspopovic, Francesco Maria Petrini, Fabrizio Vecchio

Restoration of touch after hand amputation is a desirable feature of ideal prostheses. Here, we show that texture discrimination can be artificially provided in human subjects by implementing a neuromorphic real-time mechano-neuro-transduction (MNT), which ...

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 ...

The WiseSkin artificial skin for tactile prosthetics: A power budget investigation

Christian Enz, Vladimir Kopta

The use of prosthetic hands are limited partly due to the fact that they lack the provision of sensory feedback to the user. A first step to providing sensory feedback is having adequate sensors in the prosthesis. The WiseSkin project targets the use of ar ...

Restoring Natural Sensory Feedback in Real-Time Bidirectional Hand Prostheses

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

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 ...

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 ...

Biomechanical evaluation of porous biodegradable scaffolds for revision knee arthroplasty

Dominique Pioletti, Alexandre Terrier, Alireza Roshan Ghias, Marjan Sedighi Gilani

Tibial bone defect is a critical problem for revision knee arthroplasty. Instead of using metallic spacer or cement, biodegradable scaffolds could be an alternative solution. A numerical model of a revision knee arthroplasty was thus developed to estimate ...
