Automatic Body Segment and Side Recognition of an Inertial Measurement Unit Sensor during Gait

Kamiar Aminian, Xavier Crevoisier, Robin Martin

Inertial measurement unit (IMU) sensors are widely used for motion analysis in sports and rehabilitation. The attachment of IMU sensors to predefined body segments and sides (left/right) is complex, time-consuming, and error-prone. Methods for solving the ...

Knee adduction moment decomposition: Toward better clinical decision-making

Kamiar Aminian, Xavier Crevoisier, Robin Martin

Knee adduction moment (KAM) is correlated with the progression of medial knee osteoarthritis (OA). Although a generic gait modification can reduce the KAM in some patients, it may have a reverse effect on other patients. We proposed the "decomposed ground ...

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 ...

A Wearable System for Multi-Segment Foot Kinetics Measurement

Kamiar Aminian, Julien Favre, Xavier Crevoisier, Hossein Rouhani

This study aims to design a wearable system for kinetics measurement of multi-segment foot joints in long-distance walking and to investigate its suitability for clinical evaluations. The wearable system consisted of inertial sensors (3D gyroscopes and 3D ...

Development and experimental validation of a finite element model of total ankle replacement

Alexandre Terrier, Xavier Crevoisier, Xabier Larrea

Total ankle replacement remains a less satisfactory solution compared to other joint replacements. The goal of this study was to develop and validate a finite element model of total ankle replacement, for future testing of hypotheses related to clinical is ...

Quantitative estimation of foot-flat and stance phase of gait using foot-worn inertial sensors

Kamiar Aminian, Xavier Crevoisier, Hossein Rouhani, Benoît Mariani

Time periods composing stance phase of gait can be clinically meaningful parameters to reveal differences between normal and pathological gait. This study aimed, first, to describe a novel method for detecting stance and inner-stance temporal events based ...

A Comparison Between Joint Coordinate System and Attitude Vector for Multi-segment foot Kinematics

Kamiar Aminian, Julien Favre, Hossein Rouhani, Xavier Crevoisier

The joint angles of multi-segment foot models have been primarily described using two mathematical methods: the joint coordinate system and the attitude vector. This study aimed to determine whether the angles obtained through these two descriptors are com ...

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

Kamiar Aminian, Julien Favre, Hossein Rouhani, Xavier Crevoisier

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 ...
