The effect of arm weight support on upper limb muscle synergies during reaching movements

Background: Compensating for the effect of gravity by providing arm-weight support (WS) is a technique often utilized in the rehabilitation of patients with neurological conditions such as stroke to facilitate the performance of arm movements during therap ...

Système de régulation de pression agissant localement sur la peau et le tissu sous-cutané

Yves Perriard, Yoan René Cyrille Civet, Daniel Grivon

The invention relates to a system for adjusting pressure locally acting on the skin. Said system includes a set of adjacent modules distributed so as to form a layer. Each module includes a cushion capable of changing shape and comprising a cavity, a valve ...

A two-arm coordination model for phantom limb pain rehabilitation

Ronan Boulic, Eray Molla

Following limb loss, patients usually continue having sensations on their missing limbs as if they were still present. Signicant amount of such sensations are painful and referred as Phantom Limb Pain (PLP). Previous research has shown that providing the p ...

Amputation and prosthesis implantation shape body and peripersonal space representations

Andrea Serino, Elisa Canzoneri

Little is known about whether and how multimodal representations of the body (BRs) and of the space around the body (Peripersonal Space, PPS) adapt to amputation and prosthesis implantation. In order to investigate this issue, we tested BR in a group of up ...

Design and test of a MEMS strain-sensing device for monitoring artificial knee implants

Kamiar Aminian, Philippe Renaud, Alexandre Terrier, Arnaud Bertsch, Arash Arami, Willyan Hasenkamp Carreira

This paper describes the development of a polyimide-based MEMS strain-sensing device. Finite element analysis was used to investigate an artificial knee implant and assist on device design and to optimize sensing characteristics. The sensing element of the ...

Combined Analysis of Cortical (EEG) and Nerve Stump Signals Improves Robotic Hand Control

Silvestro Micera, Jacopo Rigosa

Background. Interfacing an amputee's upper-extremity stump nerves to control a robotic hand requires training of the individual and algorithms to process interactions between cortical and peripheral signals. Objective. To evaluate for the first time whethe ...

An Actuated Transfemoral Prosthesis with Optimized Polycentric Knee Joint

Serge Pfeifer

Powered transfemoral prostheses can give above-knee amputees more flexibility than passive devices, for example allowing them to ascend and descend stairs more easily, or allowing a more natural and symmetrical gait pattern. To achieve the high torques req ...

Complementary limb motion estimation for the control of active knee prostheses

To restore walking after transfemoral amputation, various actuated exoprostheses have been developed, which control the knee torque actively or via variable damping. In both cases, an important issue is to find the appropriate control that enables user-dom ...

Instrumented Prosthesis for Knee Implants Monitoring

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

In this work we present an instrumented smart knee prosthesis for in-vivo measurement of forces and kinematics. Studying the constraints, we designed minimal sensory systems to be placed in the polyethylene part of the prosthesis. The magnetic sensors and ...

Double nerve intraneural interface implant on a human amputee for robotic hand control

Silvestro Micera, Stanisa Raspopovic, Jacopo Rigosa

Objectives: The principle underlying this project is that, despite nervous reorganization following upper limb amputation, original pathways and CNS relays partially maintain their function and can be exploited for interfacing prostheses. ...
