The aim of this study was to carry out a kinematic analysis of the lower limb during gait in subjects with asymptomatic genu recurvatum. The sagittal plane kinematics of the lower limb during gait in a group of 13 subjects with genu recurvatum was shown to be significantly different to that of a group of 13 control healthy subjects. An increase in extension and a decrease in flexion of the hip ...

Introduction: The variability of human walking has been studied for about twenty years. It appears not to be random but long-term autocorrelated, i.e. on time scales corresponding to several hundreds of gait cycles. It has been shown that the central nervous system (CNS) plays an important role in this variability. Indeed, people with CNS alterations have a different autocorrelation pattern than ...

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 ...

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 ...

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 ...

Comme tous les systèmes dynamiques, l’Homme est soumis aux lois de la mécanique. Il n’est toutefois pas réductible à une machine comme les autres : il est biologique, psychologique et social ! La douleur, définie comme une expérience sensorielle et émotionnelle désagréable associée à une lésion tissulaire réelle ou non, est une composante de nature complexe. Elle se manifeste notamment dans les ...

The 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. ...

Before and immediately after passive upper limb neurodynamic mobilizations targeting the median nerve, grip ( GF ) and load ( LF ) forces applied by the thumb, index and major fingers (three-jaw chuck pinch) were collected using a manipulandum during three different grip precision tasks: grip-lifthold- replace (GLHR), vertical oscillations (OSC), and vertical oscillations with up and down ...
