The addition of a cognitive task increases arm swing asymmetry during walking, but the characteristics and mechanism of this asymmetry are unclear. We hypothesized that this effect is lateralized and a Stroop word-colour naming task—primarily involving left hemisphere structures—would reduce right arm swing only. We recorded gait in 83 healthy subjects aged 18–80 walking normally on a treadmill and while performing a congruent and incongruent Stroop task. The primary measure of arm swing asymmetry—an index based on both three-dimensional wrist trajectories in which positive values indicate proportionally smaller movements on the right—increased significantly under dual-task conditions in those aged 40–59 and further still in the over-60s, driven by reduced right arm flexion. Right arm swing attenuation appears to be the norm in humans performing a locomotor-cognitive dual-task, confirming a prominent role of the brain in locomotor behaviour. Women under 60 are surprisingly resistant to this effect, revealing unexpected gender differences atop the hierarchical chain of locomotor control.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"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
