Intuitively, one might answer that it is, given that challenging locomotion externally (e.g., rough terrain) or internally (e.g., age-related impairments) makes our movements more unstable. Here, we investigated how young and old humans synergistically activate muscles during locomotion when different perturbation levels are introduced. Of these control signals, called muscle synergies, we analyzed the local stability and the complexity (or irregularity) over time. Surprisingly, we found that perturbations force the central nervous system to produce muscle activation patterns that are less unstable and less complex. These outcomes show that robust locomotion control in challenging settings is achieved by producing less complex control signals that are more stable over time, whereas easier tasks allow for more unstable and irregular control.</dcterms:abstract> <dcterms:issued>2020-01-24</dcterms:issued> <dc:creator>Brüll, Leon</dc:creator> <dc:contributor>Eckardt, Nils</dc:contributor> <dspace:isPartOfCollection rdf:resource=""/> <dc:creator>Kibele, Armin</dc:creator> <dc:contributor>Kibele, Armin</dc:contributor> <dc:creator>Schroll, Arno</dc:creator> <dc:contributor>Schroll, Arno</dc:contributor> <dc:contributor>Santuz, Alessandro</dc:contributor> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> </rdf:Description> </rdf:RDF>
