A Wearable Ultrasound Interface for Prosthetic Hand Control

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, Stanisa Raspopovic, Francesco Maria Petrini, Edoardo D'Anna, Ivo Strauss, Pablo Garcia del Valle, Giacomo Valle, Francesco Iberite

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, 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 ...

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 ...

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

Silvestro Micera, Stanisa Raspopovic, Fiorenzo Artoni, 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 ...
