Voluntary arm movements are preceded by dynamical and electromyographical (EMG) phenomena in "postural segments" (i.e. body segments not directly involved in the voluntary movement) called "anticipatory postural adjustments" (APA). The present study

The aim of this study is to determine, during horizontal isometric pushes carried out with upper limbs, (1) the effects of slip characteristics of support surfaces on the task performance and dynamics of the postural, i.e. body segments not directly

Determining with accuracy, the internal efforts in the human body is a great challenge in Biomechanics, particularly in Physical Therapy and Ergonomics. In this context, the present study develops a human body model that permits a non-invasive determ

International audience; It has been shown that thigh-seat contact-surface influences performance of isometric push-force with upper-limbs. The push-force performance is higher when subjects are seated with partial ischio-femoral / seat contact than w

The effects of localised muscle fatigue on group I reflex pathways were studied in the human upper limb. Activation of group I afferents originating from biceps and extensor carpi radialis (ECR) resulted in an inhibition of flexor carpi radialis (FCR

Introduction Plusieurs travaux ont montre que la mobilite de la chaine posturale est un facteur determinant dans la performance d’une tâche motrice des membres superieurs. Le but de cette etude a ete de determiner specifiquement l’effet de la lo

During voluntary step initiation (SI), propulsive forces are generated during anticipatory postural adjustments (APA) which displace the centre-of-gravity (CoG) in the desired direction. These propulsive forces are implemented by ankle synergy, bilat

International audience; This study tested the hypothesis that, in young healthy subjects, a symmetrical upper limb task involves asymmetrical postural adjustments with respect to lower limb dominance. Subjects (N=10) purposely performed a series of b

International audience; This study tested the effect of lower limb muscle fatigue induced by series of high-level isometric contractions (IC) on postural adjustments and maintenance of erect posture. Subjects (N=7) displaced a bar (grasp-bar) forward

The electromyograms of the vastus lateralis, the vastus medialis and the biceps femoris have been recorded with surface electrodes during an exhausting exercise on a Monark cycle ergometer, derived from the Wingate test (a 45 second all-out exercise
