Chronic low back pain patients walk with locally altered spinal kinematics

Julien Favre, Brigitte Jolles-Haeberli

Various studies have reported alterations of spinal kinematics in patients with chronic low back pain (CLBP) during gait. However, while recent findings stressed the importance of multi-segment analysis, most of prior gait studies modelled the lumbar spine ...

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 ...

Quantitative regional and sub-regional analysis of femoral and tibial subchondral bone mineral density (sBMD) using computed tomography (CT): comparison of non-osteoarthritic (OA) and severe OA knees

Julien Favre, Brigitte Jolles-Haeberli

Objective: This study aimed to compare subchondral bone mineral density (sBMD) between non-radiographic osteoarthritic (OA) and medial femorotibial OA knees, using computed tomography (CT). Design: CT exams from 16 non-radiographic OA (KL grade < 2) and 16 ...

Changes in lower limb biomechanics when following floor-projected foot placement visual cues for gait rehabilitation

Julien Favre, Brigitte Jolles-Haeberli

Background: Lately, the projection of foot placement visual cues onto the floor has been considered for use in gait rehabilitation. While promising, this approach needs further basic assessment to ensure proper uses. Research question: Does following floor ...

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 ...

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 ...

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 ...

Segmentation of Foot and Ankle Complex based on Kinematic Criteria

Kamiar Aminian, Julien Favre, Brigitte Jolles-Haeberli, Hossein Rouhani, 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 ...

Gait events during turning can be detected using kinematic features originally proposed for the analysis of straight-line walking

Julien Favre, Brigitte Jolles-Haeberli

There is a growing interest for turning biomechanics notably because it is a more challenging task than straight-line walking during which some gait impairments are increased. Detecting heel-strike (HS) and toe-off (TO) events using the trajectory of marke ...

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 ...

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 ...

Changes in ambulatory knee adduction moment with lateral wedge insoles differ with respect to the natural foot progression angle

Julien Favre, Brigitte Jolles-Haeberli

Lateral wedge insoles (LWI) have been proposed to reduce the knee adduction moment (KAM) during walking; a biomechanical modification notably sought in case of medial knee osteoarthritis. However, the inter-individual inconsistency in KAM changes with LWI ...

Decreasing the ambulatory knee adduction moment without increasing the knee flexion moment individually through modifications in footprint parameters: A feasibility study for a dual kinetic change in healthy subjects

Julien Favre, Brigitte Jolles-Haeberli

Gait retraining is gaining in interest to reduce loading associated to knee osteoarthritis (OA) progression. So far, interventions focused on reducing the peak knee adduction moment (pKAM) and it remains unclear if this can be done individually without inc ...

Quaternion-based fusion of gyroscopes and accelerometers to improve 3D angle measurement

Kamiar Aminian, Julien Favre

Two methods to fuse a 3D gyroscope with a 3D accelerometer in order to measure rotations are presented. They are compared with a method requiring only a 3D gyroscope and assessed with a reference system. The good reported accuracies make this system suitab ...
