Computationally efficient model to predict the deformations of a cellular foot orthotic
(Elsevier, 2022-04-21)Background Foot orthotics (FOs) are frequently prescribed to provide comfortable walking for patients. Finite element (FE) simulation and 3D printing pave the way to analyse, optimize and fabricate functionally graded lattice FOs where the local ... -
Effect of expertise on shoulder and upper limb kinematics, electromyography, and estimated muscle forces during a lifting task
(SAGE, 2020-11-25)Objective To highlight the working strategies used by expert manual handlers compared with novice manual handlers, based on recordings of shoulder and upper limb kinematics, electromyography (EMG), and estimated muscle forces during a lifting ... -
Ilio-femoral ligament strains during the flexion-abduction-external rotation test : a cadaveric study
(Elsevier, 2023-02-02)Background: Flexion-abduction-external-rotation (FABER) test is one of the most used tests during the clinical assessment of the hip joint. The limited range of motions reached could be due to iliofemoral ligament tightness, but no study has assessed ... -
Intracapsular pressures in the flexion-abduction-external rotation and flexion-adduction-internal rotation tests and their comparison with classic hip range of motion : a cadaveric assessment
(Elsevier, 2021-11-11)Background Flexion-Abduction-External-Rotation and Flexion-Adduction-Internal-Rotation tests are used to reproduce pain at the hip during clinical assessment. As pain can be elicited by high intracapsular pressure, no information has been provided ... -
Lower limb extension is improved in fast walking condition in children who walk in crouch gait
(Taylor and Francis, 2018-09-28)Background and purpose: The strategies for walking fast have never been reported in children with cerebral palsy who walk in crouch gait. This study aimed to assess to what extent children who walk in crouch gait are able to increase their gait speed ... -
Lower trapezius weakness and shoulder complex biomechanics during the tennis serve
(Lippincott, Williams and Wilkins, 2019-07-02)Purpose This study aimed to assess the effect of lower trapezius (LT) weakness on humeral and scapular kinematics and shoulder muscle activity during the tennis serve. Methods Fifteen competitive male tennis players (age, 23.8 ± 3.4 yr; height, ... -
Muscle co-contraction and co-activation in cerebral palsy during gait : a scoping review
(Elsevier, 2023-07-09)Background Cerebral palsy (CP) results from an injury to a developing brain. Muscle activation patterns during walking are disrupted in individuals with CP. Indeed, excessive muscle co-contraction or co-activation (MCo/MCa) is one of the characteristics ... -
Numerical homogenization of a linearly elastic honeycomb lattice structure and comparison with analytical and experimental results
(Elsevier, 2022-01-15)This paper presents a verification and validation analysis of Finite Element (FE) models predicting the mechanical response of linearly elastic honeycomb structures. We have studied three main models, namely: analytical models based on beam theories, ... -
An optimization method tracking EMG, ground reactions forces and marker trajectories for musculo-tendon forces estimation in equinus gait
(Frontiers Media, 2019-07-16)In the context of neuro-orthopedic pathologies affecting walking and thus patients' quality of life, understanding the mechanisms of gait deviations and identifying the causal motor impairments is of primary importance. Beside other approaches, ... -
Proximal-to-distal sequences of attack and release movements of expert pianists during pressed-staccato keystrokes
(Taylor and Francis, 2021-08-12)The aims of this study were to i) evaluate proximal-to-distal sequencing (PDS) in pianists’ attack and release movements during pressed-staccato keystrokes, and ii) investigate if trunk motion facilitates PDS of upper-limb movements. Nine expert pianists ... -
Reliability of the kinematic theory parameters during handwriting tasks on a vertical setup
(Elsevier, 2021-10-07)Background The Kinematic Theory and its Sigma–Lognormal model have been used extensively in motor control analyses. It has recently shown promise in its ability to detect neuromuscular fatigue in the shoulder. The use of an ergonomic setup composed ... -
Shoulder electromyography-based indicators to assess manifestation of muscle fatigue during laboratory-simulated manual handling task
(Taylor and Francis, 2021-08-14)Muscle fatigue is a risk factor for developing shoulder musculoskeletal disorders. The aim of this study was to identify shoulder electromyographic indicators that are most indicative of muscle fatigue during a laboratory simulated manual handling task. ... -
Surrogate optimization of a lattice foot orthotic
(Elsevier, 2022-11-30)Background: Additive manufacturing enables to print patient-specific Foot Orthotics (FOs). In FOs featuring lattice structures, the variation of the cell’s dimensions provides a locally variable stiffness to meet the therapeutic needs of each patient. ... -
Time history of upper-limb muscle activity during isolated piano keystrokes
(Elsevier, 2020-08-28)Playing-related musculoskeletal disorders (PRMDs) in pianists can lead to the cessation of performance-related activities. A better understanding of the impact of performance parameters on muscle activities could help improve prevention of pianists’ ...
