Stability

Time-varying activities can always be modeled as dynamical systems. For instance, when looking at rhythmic movements the corresponding state variables are modeled as self-sustaining oscillators. While such an oscillator in itself may already account for some complex behaviors, we particularly focus on the stability of coordination patterns, i.e. on the interactions between oscillators – think of homologous limbs for which the interaction describes the left/right crosstalk and interference. The stability of coordination may drastically change as a consequence of alterations in the strength of the coupling. This may yield  involuntary, spontaneous transitions between coordination.

Bimanual Interaction

Age effects in bimanual coordination

Age effects in bimanual coordination

We study the relationship between altered inter- and intra-hemispheric structural and functional connectivities in the motor the network. Our focus is on the correlation between connectivies and declined motor performance in the elderly.
Relative Phase Dynamics

Relative Phase Dynamics

The stability of coordination can often be addressed via the relative phase between the individual limb movements. We are studying in detail the effect of different interactions between limbs, effects of noise and non-autonomous forcing.
Bimanual Coordination

Bimanual Coordination

We study how different control processes contribute to stabilizing the coordination between limbs, and how they change as a function of, e.g., movement frequency and amplitude, learning, development and pathology.
Move-Age

Move-Age

Understanding Ageing and Mobility. Funded by the EU as part of the Erasmus Mundus program, this international training network involves 40-odd PhD students studying age-related changes in human movement.

Perturbing Stability

Stability of Gait

Stability of Gait

Walking on two legs is inherently unstable. Still, we humans perform remarkable well at it, mostly without falling. We measure and perturbed walking to gain more insight into the role of the central nervous system in controlling gait stability.
