Voluntarily changing step length or step width affects dynamic stability of human walking

Highlights ► We quantify how step characteristics influence variability and stability of walking. ► We examined voluntary changes in step width and step length. ► Any change in step characteristics was associated with increased step variability. ► Short-term, voluntary changes in step width and step...
