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 ...

Automatic measurement of key ski jumping phases and temporal events with a wearable system

Kamiar Aminian, Julien Favre, Julien Chardonnens, Benoît Le Callennec

We propose a new method, based on inertial sensors, to automatically measure at high frequency the durations of the main phases of ski jumping (i.e. take-off release, take-off, and early flight). The kinematics of the ski jumping movement were recorded by ...

An effortless procedure to align the local frame of an inertial measurement unit to the local frame of another motion capture system

Kamiar Aminian, Julien Favre, Julien Chardonnens

Inertial measurement units (IMUs) offer great opportunities to analyze segmental and joints kinematics. When combined with another motion capture system (MCS), for example, to validate new IMU-based applications or to develop mixed systems, it is necessary ...

Business/IT Alignment in Practice: Lessons Learned From a Requirements Project at P&G

Gil Regev, Julien Favre, Alain Wegmann

One of the main objectives of the alignment of Business and IT in both small and large organizations is to improve the chances for an IT department to provide services that result in business success. An essential phase for this alignment is the definition ...

Ambulatory measurement of ankle kinetics for clinical applications

Kamiar Aminian, Julien Favre, Hossein Rouhani, Xavier Crevoisier

This study aimed to design and validate the measurement of ankle kinetics (force, moment, and power) during consecutive gait cycles and in the field using an ambulatory system. An ambulatory system consisting of plantar pressure insole and inertial sensors ...

Segmentation of Foot and Ankle Complex based on Kinematic Criteria

Kamiar Aminian, Julien Favre, Hossein Rouhani, Brigitte Jolles-Haeberli, Xavier Crevoisier

Although various foot models were proposed for kinematics assessment using skin makers, no objective justification exists for the foot segmentations. This study proposed objective kinematic criteria to define which foot joints are relevant (dominant) in sk ...

Outcome evaluation of ankle osteoarthritis treatments: Plantar pressure analysis during relatively long-distance walking

Kamiar Aminian, Julien Favre, Hossein Rouhani, Xavier Crevoisier

Background: This study aimed to use plantar pressure analysis in relatively long-distance walking for objective outcome evaluation of ankle osteoarthritis treatments, i.e., ankle arthrodesis and total ankle replacement. Methods: Forty-seven subjects in fou ...

Analysis of inter-segment coordination during the take-off of ski jumping

Kamiar Aminian, Julien Favre, Julien Chardonnens

In ski jumping, take-off (TO) is considered as the most important phase. While spatio-temporal features have been identified during this phase, inter-segment coordination has never been investigated. This study proposed a new method using body worn inertia ...

A new method for unconstrained measurement of knee joint angle and timing in alpine skiing : Comparison of crossover and crossunder turns

Kamiar Aminian, Julien Favre, Julien Chardonnens

Timing is an important part in the analysis of alpine skiing technique. Key events extracted from dynamics and kinematics of ski were previously proposed, but timing of body segments kinematics is also required to understand the biomechanics and to assess ...

Orientation of body segments in ski jumps using wearable sensors: Analysis of relevant parameters during stable flight phase

Kamiar Aminian, Julien Favre, Julien Chardonnens

Biomechanics analysis of the ski jump is highly required. Some parameters and their interrelations have been reported in previous research studies limited to few athletes. The generalization of these parameters to athletes of various levels and under train ...
