Body vibration and its transmission in alpine ski racing

Kamiar Aminian, Benedikt Fasel

The aim of the study was to quantify the vibrations occurring at the lower limbs and the trunk during alpine ski racing. Four European Cup level athletes skied each three runs on a typical giant slalom course. For each turn, power spectral density (PSD) of ...

Soft tissue artifact distribution on lower limbs during treadmill gait: Influence of skin markers' location on cluster design

Kamiar Aminian, Arnaud Barré

© 2015 Elsevier Ltd. Segment poses and joint kinematics estimated from skin markers are highly affected by soft tissue artifact (STA) and its rigid motion component (STA. RM ). While four marker-clusters could decrease the STA non-rigid motion d ...

Smart Knee Prosthesis for Orthopedic Surgery: the implantable and wearable Measurement System

Kamiar Aminian, Philippe Renaud, David Forchelet, Arash Arami

Recent advances in remote powering and telemetry permitted the use of sensors inside body. A few studies have been already done on smart knee prostheses, but all focused on monitoring the in-vivo contact forces and moments. A smart design, compatible with ...

Improving activity recognition using a wearable barometric pressure sensor in mobility-impaired stroke patients

Kamiar Aminian, Anisoara Ionescu, Arash Arami, Fabien Massé

Background Stroke survivors often suffer from mobility deficits. Current clinical evaluation methods, including questionnaires and motor function tests, cannot provide an objective measure of the patients’ mobility in daily life. Physical activity performa ...

A Bayesian Approach for Pervasive Estimation of Breaststroke Velocity Using a Wearable IMU

Kamiar Aminian, Farzin Dadashi, Grégoire Millet

An ubiquitous assessment of swimming velocity (main metric of the performance) is essential for the coach to provide a tailored feedback to the trainee. We present a probabilistic framework for the data-driven estimation of the swimming velocity at every c ...

Locally Linear Neuro-Fuzzy Estimate of the Prosthetic Knee Angle and its Validation in a Robotic Simulator

Kamiar Aminian, Natacha Vida Martins, Arash Arami

Here we present a low-power magnetic measurement system based on only two Hall-effect elements and a permanent magnet integrated into a smart knee prosthesis to accurately measure knee flexion-extension. The smart prosthesis was tested in a robotic knee si ...

Using inertial sensors for reconstructing 3D full-body movement in sports - possibilities and limitations on the example of alpine ski racing

Kamiar Aminian, Benedikt Fasel

The present study investigates if inertial sensors could be used for reconstructing 3D full body movements in sports. On the example of alpine ski racing, it was demonstrated that inertial sensors allow computing meaningful parameters related to a skier’s ...

An inertial sensor-based system for spatio-temporal analysis in classic cross-country skiing diagonal technique

Kamiar Aminian, Julien Favre, Julien Chardonnens, Benedikt Fasel

The present study proposes a method based on ski fixed inertial sensors to automatically compute spatio-temporal parameters (phase durations, cycle speed and cycle length) for the diagonal stride in classical cross-country skiing. The proposed system was v ...

Measurement of the dynamics in ski jumping using a wearable inertial sensor-based system

Kamiar Aminian, Julien Favre, Julien Chardonnens

Dynamics is a central aspect of ski jumping, particularly during take-off and stable flight. Currently, measurement systems able to measure ski jumping dynamics (e.g., 3D cameras, force plates) are complex and only available in few research centres worldwi ...

Smart instrumentation for determination of ligament stiffness and ligament balance in total knee arthroplasty

Kamiar Aminian, Philippe Renaud, Arnaud Bertsch, Brigitte Jolles-Haeberli, Arash Arami, Willyan Hasenkamp Carreira

Ligament balance is an important and subjective task performed during total knee arthroplasty (TKA) procedure. For this reason, it is desirable to develop instruments to quantitatively assess the soft-tissue balance since excessive imbalance can accelerate ...

Enclosed Electronic System for Force Measurements in Knee Implants

Kamiar Aminian, Philippe Renaud, Arnaud Bertsch, Peter Ryser, Eric Meurville, David Forchelet, Arash Arami, Matteo Simoncini

Total knee arthroplasty is a widely performed surgical technique. Soft tissue force balancing during the operation relies strongly on the experience of the surgeon in equilibrating tension in the collateral ligaments. Little information on the forces in th ...
