Estimation of prosthetic knee angles via data fusion of implantable and wearable sensors

Kamiar Aminian, Arash Arami, Arnaud Barré, Roderik Berthelin

In this work, we studied a combination of embedded magnetic measurement system in a knee prosthesis and wearable inertial sensors to estimate two knee joint rotations namely flexion-extension and internal-external rotations. The near optimal sensor configu ...

In vitro quantification of the performance of model-based mono-planar and bi-planar fluoroscopy for 3D joint kinematics estimation

Arnaud Barré

Model-based mono-planar and bi-planar 3D fluoroscopy methods can quantify intact joints kinematics with performance/cost trade-off. The aim of this study was to compare the performances of mono- and bi-planar setups to a marker-based gold-standard, during ...

Sensitivity of hip tissues contact evaluation to the methods used for estimating the hip joint center of rotation

Daniel Thalmann, Ronan Boulic, Jérôme Schmid, Ehsan Arbabi

Computer-based simulations of human hip joints generally include investigating contacts happening among soft or hard tissues during hip movement. In many cases, hip movement is approximated as rotation about an estimated hip center. In this paper, we inves ...

Simulation of total ankle replacement using numerical modeling

Sara Molins Cabaní

The ankle is a complex joint of the human body which is most often affected by trauma. Osteoarthritis is a joint disease that can require surgical intervention and when it affects the ankle there are two options to achieve pain relief. For years ankle fusi ...

Measurement of Multi-segment Foot Joint Angles During Gait Using a Wearable System

Kamiar Aminian, Julien Favre, Xavier Crevoisier, Hossein Rouhani

Usually the measurement of multi-segment foot and ankle complex kinematics is done with stationary motion capture devices which are limited to use in a gait laboratory. This study aimed to propose and validate a wearable system to measure the foot and ankl ...

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 ...

Importance of polyethylene thickness in total shoulder arthroplasty: A finite element analysis

Dominique Pioletti, Alexandre Terrier, Alain Farron, Vittoria Brighenti

Background: Articular surfaces reconstruction is essential in total shoulder arthroplasty. Because of the limited glenoid bone support, thin glenoid component could improve anatomical reconstruction, but adverse mechanical effects might appear. Methods: Wi ...

Buckling-induced encapsulation of structured elastic shells under pressure

Pedro Miguel Nunes Pereira de Almeida Reis

We introduce a class of continuum shell structures, the Buckliball, which undergoes a structural transformation induced by buckling under pressure loading. The geometry of the Buckliball comprises a spherical shell patterned with a regular array of circula ...

ScarlETH: Design and control of a planar running robot

Roland Siegwart, Marco Hutter

This paper introduces the mechanical design and the control concept of the Series Compliant Articulated Robotic Leg ScarlETH which was developed at ETH Zurich for fast, efficient, and versatile locomotion. Inspired by biological systems, we seek to achieve ...
