Understanding motor control and impairment: An upper-limb model for muscular assessment

Tristan Jean Robin Barjavel

The human upper limb is a complex musculoskeletal system that can still perform various tasks with impressive efficacy thanks to the ability of the central nervous system to control and modulate the activation of more than 40 muscles. Stroke is a leading ...

Microtubule-mediated GLUT4 trafficking is disrupted in insulin-resistant skeletal muscle

Martinus Adela Maria Gijs, Raphaël Etienne Jean Trouillon, Martin Rainer Wohlwend

Microtubules serve as tracks for long-range intracellular trafficking of glucose transporter 4 (GLUT4), but the role of this process in skeletal muscle and insulin resistance is unclear. Here, we used fixed and live-cell imaging to study microtubule-based ...

Muscle activation variability is inversely correlated with walking speed

Auke Ijspeert, Florin Dzeladini

Individuals with motor impairments typically walk at much slower speeds than their unimpaired counter- parts, yet their gait data is still evaluated against the relatively faster gait of healthy subjects. Therefore a good understanding of unimpaired gait a ...
