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)...

Behavioral and neural adaptations in response to five weeks of balance training in older adults: a randomized controlled trial

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

In: Journal of Negative Results in BioMedicine, 2017, vol. 16, p. 11

Background: While the positive effect of balance training on age-related impairments in postural stability is well-documented, the neural correlates of such training adaptations in older adults remain poorly understood. This study therefore aimed to shed more light on neural adaptations in response to balance training in older adults.Methods: Postural stability as well as spinal reflex and...

Is young age a limiting factor when training balance? Effects of child-oriented balance training in children and adolescents

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

In: Pediatric Exercise Science, 2017, p. 1–26

Purpose: Balance training studies in children reported conflicting results without evidence for improvements in children under the age of eight. The aim of this study therefore was to compare balance training adaptations in children of different age groups to clarify whether young age prevents positive training outcomes.Method: The effects of five weeks of child-oriented balance training were...

Task-dependent changes of corticospinal excitability during observation and motor imagery of balance tasks

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

In: Neuroscience, 2015, vol. 303, p. 535–543

Non-physical balance training has demonstrated to be efficient to improve postural control in young people. However, little is known about the potential to increase corticospinal excitability by mental simulation in lower leg muscles. Mental simulation of isolated, voluntary contractions of limb muscles increase corticospinal excitability but more automated tasks like walking seem to have no or...
