Article scientifique
When a Hamiltonian system undergoes a stochastic, time-dependent anharmonic perturbation,
the values of its adiabatic invariants as a function of time follow a distribution whose shape
obeys a Fokker–Planck equation. The effective dynamics of the body’s centre-of-mass during human
walking is expected to represent such a stochastically perturbed dynamical system. By studying, in
phase space, the ...
ZN-balls: Solitons from ZN-symmetric scalar field theory

Article scientifique
We 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 ...

- Article scientifique
Article scientifique
Nowadays, the better assessment of low back pain (LBP) is an important challenge, as it is
the leading musculoskeletal condition worldwide in terms of years of disability. The objective of this
study was to evaluate the relevance of various machine learning (ML) algorithms and Sample Entropy
(SampEn), which assesses the complexity of motion variability in identifying the condition of low back
pain. ...
Many-Quark Interactions: Large-N Scaling and Contribution to Baryon Masses

- Article scientifique
Article scientifique
Starting from an effective Hamiltonian modeling, of a baryon made of N identical quarks in
the large-N approach of QCD, we obtain analytical formulas, allowing to estimate the contributions
of multiquark interactions to the baryon mass. The cases of vanishing (mass spectrum) and nonvanishing
(baryon melting) temperatures are treated.
Head Pitch Angular Velocity Discriminates (Sub-)Acute Neck Pain Patients and Controls Assessed with the DidRen Laser Test

- Article scientifique
Article scientifique
Understanding neck pain is an important societal issue. Kinematic data from sensors may help to gain insight into the pathophysiological mechanisms associated with neck pain through a quantitative sensorimotor assessment of one patient. The objective of this study was to evaluate the potential usefulness of artificial intelligence with several machine learning (ML) algorithms in assessing neck ...
Sample Entropy as a Tool to Assess Lumbo-Pelvic Movements in a Clinical Test for Low-Back-Pain Patients

- Article scientifique
Article scientifique
Low 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 ...
High Specificity of Single Inertial Sensor-Supplemented Timed Up and Go Test for Assessing Fall Risk in Elderly Nursing Home Residents

- Article scientifique
Article scientifique
The Timed Up and Go test (TUG) is commonly used to estimate the fall risk in the elderly. Several ways to improve the predictive accuracy of TUG (cameras, multiple sensors, other clinical tests) have already been proposed. Here, we added a single wearable inertial measurement unit (IMU) to capture the residents’ body center-of-mass kinematics in view of improving TUG’s predictive accuracy. The aim ...
Perceived Usefulness of Telerehabilitation of Musculoskeletal Disorders: A Belgium–France Pilot Study during Second Wave of COVID-19 Pandemic

Article scientifique
Background: 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 ...
