Title: Relationships between dynamic balance and asymmetry of walking

Abstract: One common feature of human walking is to adjust patterns in response to a novel walking environment without falling. For example, people gradually reduced step length asymmetry while walking on a split-belt treadmill which has two independent belts capable of moving at different speeds. Although this process is accompanied by a concomitant reduction in energetic cost and mechanical work, people also adopt gradual reductions in measures of dynamic balance during adaptation. However, it is yet to be determined if changes in balance metrics are a

byproduct of adaptation or if a desire to improve balance drives adaptation. Therefore, a complete understanding of locomotor adaptation requires an analysis of the causal link between balance control and spatiotemporal asymmetry. Furthermore, the conventional rehabilitation often aims to reduce asymmetry of people post-stroke who naturally have an asymmetric walking pattern due to combinations of impaired sensorimotor function. Although recent studies showed that smaller spatiotemporal asymmetry was associated with better balance control of post-stroke, it is unclear if immediate reductions in asymmetry improve dynamic balance during walking. Therefore, it is essential to determine how reducing asymmetry influences dynamic balance during walking in people post-stroke. These findings can be used in research investigating the effects of an intervention or rehabilitation on dynamic balance control during healthy walking or gait of stroke.
