Aging effects on prefrontal cortex oxygenation in a posture-cognition dual-task: an fNIRS pilot study

Marusic, Uros ; Taube, Wolfgang ; Morrison, Shawnda A. ; Biasutti, Lea ; Grassi, Bruno ; Pauw, Kevin De ; Meeusen, Romain ; Pisot, Rado ; Ruffieux, Jan

In: European Review of Aging and Physical Activity, 2019, vol. 16, no. 1, p. 2

The aging process alters upright posture and locomotion control from an automatically processed to a more cortically controlled one. The present study investigated a postural-cognitive dual-task paradigm in young and older adults using functional Near- Infrared Spectroscopy (fNIRS).Methods: Twenty healthy participants (10 older adults 72 ± 3 y, 10 young adults 23 ± 3 y) performed a...

Accompagnement partagé dans une formation en alternance à l’enseignement instrumental = Supporting the training of instrument teaching in a shared way within a dual training

Giovannini-Cartulano, Valentina ; Coen, Pierre-François ; Güsewell, Angelika ; Paukovics, Elsa

In: Formation et profession : Revue scientifique internationale en éducation, 2018, vol. 26, no. 3, p. 43-56

Conducted in a Swiss music university along with the implementation of a new training system for a master’s course of instrument teaching, this research aims to highlight how the beliefs about support by the different actors involved (pedagogy teachers, didactic teachers as well as practical training teachers) shape their practices, postures and accompaniment behaviors of the...

Age-dependent adaptations to anticipated and non-anticipated perturbations after balance training in children

Wälchli, Michael ; Keller, Martin ; Ruffieux, Jan ; Mouthon, Audrey ; Taube, Wolfgang

In: Human Movement Science, 2018, vol. 59, p. 170–177

Postural control undergoes rapid changes during child development. However, the influence of balance training (BT) on the compensation of perturbations has not yet been investigated in children. For this purpose, young (6.7 ± 0.6 years) and old children (12.0 ± 0.4 years) were exposed to externally induced anticipated (direction known) and non-anticipated (direction unknown)...

Age-related differences in cortical and subcortical activities during observation and motor imagery of dynamic postural tasks: an FMRI study

Mouthon, Audrey ; Ruffieux, Jan ; Mouthon, Michael ; Hoogewoud, Henri-Marcel ; Annoni, Jean-Marie ; Taube, Wolfgang

In: Neural Plasticity, 2018, p. -

Age-related changes in brain activation other than in the primary motor cortex are not well known with respect to dynamic balance control. Therefore, the current study aimed to explore age-related differences in the control of static and dynamic postural tasks using fMRI during mental simulation of balance tasks. For this purpose, 16 elderly (72 ± 5 years) and 16 young adults...

Age-related differences in corticospinal excitability during observation and motor imagery of balance tasks

Mouthon, Audrey A. ; Ruffieux, Jan ; Keller, Martin ; Taube, Wolfgang

In: Frontiers in Aging Neuroscience, 2016, vol. 8, p. -

Postural control declines across adult lifespan. Non-physical balance training has been suggested as an alternative to improve postural control in frail/immobilized elderly people. Previous studies showed that this kind of training can improve balance control in young and older adults. However, it is unclear whether the brain of young and older adults is activated differently during mental...

Age-related decrease in motor cortical inhibition during standing under different sensory conditions

Papegaaij, Selma ; Taube, Wolfgang ; Hogenhout, Margot ; Baudry, Stéphane ; Hortobágyi, Tibor

In: Frontiers in Aging Neuroscience, 2014, vol. 6, p. 126

Background: Although recent studies point to the involvement of the primary motor cortex in postural control, it is unknown if age-related deterioration of postural control is associated with changes in motor cortical circuits. We examined the interaction between age and sensory condition in the excitability of intracortical motor pathways as indexed by short-interval intracortical inhibition...

Aging causes a reorganization of cortical and spinal control of posture

Papegaaij, Selma ; Taube, Wolfgang ; Baudry, Stéphane ; Otten, Egbert ; Hortobágyi, Tibor

In: Frontiers in Aging Neuroscience, 2014, vol. 6, p. 28

Classical studies in animal preparations suggest a strong role for spinal control of posture. In humans it is now established that the cerebral cortex contributes to postural control of unperturbed and perturbed standing. The age-related degeneration and accompanying functional changes in the brain, reported so far mainly in conjunction with simple manual motor tasks, may also affect the...
