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

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 ...

An Adaptive Neuromuscular Controller for Assistive Lower-Limb Exoskeletons: A Preliminary Study on Subjects with Spinal Cord Injury

Auke Ijspeert, Florin Dzeladini, Amy Roning Wu, Tycho Jan Henricus Brug

Versatility is important for a wearable exoskeleton controller to be responsive to both the user and the environment. These characteristics are especially important for subjects with spinal cord injury (SCI), where active recruitment of their own neuromusc ...

Influence of an Assistive Hip Orthosis on Gait

Hannes Bleuler, Mohamed Bouri, Jeremy Olivier, Amalric Louis Ortlieb

Powered orthoses are leading to an imminent change in the field of assistance. The major challenges faced by the technology concern the management of the interaction between the user and the wearable device and the coordination between the user intention a ...

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 ...

Alteration and recovery of arm usage in daily activities following rotator cuff surgery

Kamiar Aminian, Alain Farron, Brigitte Jolles-Haeberli, Cyntia Duc

Background: The objective measurement of dominant/nondominant arm use proportion in daily life may provide relevant information on healthy and pathologic armbehavior. This prospective case-control study explored the potential of such measurements as indica ...

Automatic Hand Phantom Map Detection Methods

Christian Enz, Claudio Bruschini, Huaiqi Huang, Tao Li, Jörn Justiz

Many amputees have maps of referred sensation from their missing hand on their residual limb (phantom maps). This skin area can serve as a target for providing amputees with tactile sensory feedback. Providing tactile feedback on the phantom map can improv ...

Does an intraneural interface short-term implant for robotic hand control modulate sensorimotor cortical integration? An EEG-TMS co-registration study on a human amputee

Silvestro Micera, Leopoldo Rossini

Purpose: Following limb amputation, central and peripheral nervous system relays partially maintain their functions and can be exploited for interfacing prostheses. The aim of this study is to investigate, for the first time by means of an EEG-TMS co-regis ...

Time-domain algorithm for single-photon laser-Doppler flowmetry at large interoptode spacing in human bone

Dimitri Nestor Alice Van De Ville

A new laser-Doppler flowmeter at large interoptode spacing, based on single-photon counting (single-photon laser-Doppler flowmetry [SP-LDF]) and allowing assessment of blood flow deep in bone tissue, is proposed and implemented. To exploit the advantages 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 ...
