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...

Brachialis muscle activity can be assessed with surface electromyography

Staudenmann, Didier ; Taube, Wolfgang

In: Journal of Electromyography and Kinesiology, 2015, vol. 25, no. 2, p. 199–204

The brachialis muscle (BR) represents an important elbow flexor and its activity has so far mainly been measured with intramuscular electromyography (EMG). The aim of this study was to examine whether the activity of the BR can be assessed with surface EMG without interference from the biceps brachii (BB). With eight subjects we measured surface EMG of the arm flexor synergists, BR, BB, and...
