Motor strategies and adiabatic invariants: The case of rhythmic motion in parabolic flights
05 août 2021, CeREF TechniqueArticle scientifiqueThe role of gravity in human motor control is at the same time obvious and difficult to isolate. It can be assessed by performing experiments in variable gravity. We propose that adiabatic invariant theory may be used to reveal nearly conserved quantities in human voluntary rhythmic motion, an individual being seen as a complex time-dependent dynamical system with bounded motion in phase space. ... -

Occupational Risk Factors for Musculoskeletal Disorders among Workers in Dairy Diversification
11 janvier 2024, CeREF SantéArticle scientifiqueAbstract Background: In a changing European agricultural context, diversification of dairy farms is gaining attention. This study seeks to (1) assess musculoskeletal pain prevalence associated with tasks such as butter, yogurt, and cheese production; and (2) analyze associated risks. Methods: Observing 31, mostly female, workers, we utilized the ERGOROM questionnaire, a methodology adapted from ... -
Opinion sur l’efficacité de la prise en charge en kinésithérapie des troubles neuro-musculo- squelettiques par téléréadaptation
18 avril 2020, HE Louvain en HainautArticle scientifiqueEn cette période de confinement liée au coronavirus 2 du syndrome respiratoire aigu sévère (SRAS-CoV-2), l’objectif de cet article est de formuler une opinion sur l'efficacité de la prise en charge kinésithérapique des troubles neuro-musculo-squelettiques (TNMS) par téléréadaptation (TR) ainsi que des guidelines pour les kinésithérapeutes. L’efficacité de la prise en charge en kinésithérapie par TR ... -
Perceived Usefulness of Telerehabilitation of Musculoskeletal Disorders: A Belgium–France Pilot Study during Second Wave of COVID-19 Pandemic
22 novembre 2021, CeREF TechniqueArticle scientifiqueBackground: COVID-19 has affected the practice of physiotherapy, and telerehabilitation (TR) may be seen as an alternative model of care if it is accepted by patients and physiotherapists. This study investigates the perceived usefulness of TR and the intention to use it among physiotherapists and patients from Belgium and France concerned with musculoskeletal disorders (MSDs) during the pandemic ... -
Q-balls and charged Q-balls in a two-scalar field theory with generalized Henon-Heiles potential
30 avril 2024, CeREF TechniqueArticle scientifiqueWe construct Q-ball solutions from a model consisting of one massive scalar field ξ and one massive complex scalar field ϕ interacting via the cubic couplings g1ξϕ ϕ þ g2ξ3, typical of Henon-Heiles-like potentials. Although being formally simple, these couplings allow for Q-balls. In one spatial dimension, analytical solutions exist, either with vanishing or nonvanishing ϕ. In three spatial ... -

Sample Entropy as a Tool to Assess Lumbo-Pelvic Movements in a Clinical Test for Low-Back-Pain Patients
22 mars 2022, CeREF TechniqueArticle scientifiqueLow back pain (LBP) obviously reduces the quality of life but is also the world’s leading cause of years lived with disability. Alterations in motor response and changes in movement patterns are expected in LBP patients when compared to healthy people. Such changes in dynamics may be assessed by the nonlinear analysis of kinematical time series recorded from one patient’s motion. Since sample ... -

Timed Up and Go and Six-Minute Walking Tests with Wearable Inertial Sensor: One Step Further for the Prediction of the Risk of Fall in Elderly Nursing Home People
05 juin 2020, CeREF TechniqueArticle scientifiqueAssessing the risk of fall in elderly people is a difficult challenge for clinicians. Since falls represent one of the first causes of death in such people, numerous clinical tests have been created and validated over the past 30 years to ascertain the risk of falls. More recently, the developments of low-cost motion capture sensors have facilitated observations of gait differences between fallers ... -
Utilisation de la réalité virtuelle dans un test clinique adaptatif de mobilité cervicale
25 février 2021, CeREF TechniqueActe de conférence ou de colloqueDifférents tests et outils cliniques existent dans le but d’évaluer les aptitudes fonctionnelles d’un patient, d’évaluer ses progrès ou même de l’entraîner. Cependant, ces outils cliniques présentent certains problèmes : Ils sont rarement adaptables aux capacités du patient car non modulaire, peu ludique pour de jeunes patients ou sur le long terme. L’objectif de la présente recherche est d’utiliser ... -

Wearable Sensors Applied in Movement Analysis
30 novembre 2022, CeREF TechniqueLivre/Ouvrage ou monographieRecent advances in electronics have led to sensors whose sizes and weights are such that they can be placed on living systems without impairing their natural motion and habits. They may be worn on the body as accessories or as part of the clothing and enable personalized mobile information processing. Wearable sensors open the way for a nonintrusive and continuous monitoring of body orientation, ... -

ZN-balls: Solitons from ZN-symmetric scalar field theory
28 novembre 2022, CeREF TechniqueArticle scientifiqueWe discuss the conditions under which static, finite-energy, configurations of a complex scalar field ϕ with constant phase and spherically-symmetric norm exist in a potential of the form V(ϕ*ϕ, ϕ^N, ϕ^*N) with N ∈ N and N ≥ 2, i.e., a potential with a ZN-symmetry. Such configurations are called ZN-balls. We build explicit solutions in (3 + 1)-dimensions from a model mimicking effective field ...
