Temporal structure of variability reveals similar control mechanisms during lateral stepping and forward walking

Temporal structure of variability reveals similar control mechanisms during lateral stepping and forward walking

Highlights ► We investigated the structure of variability for a lateral stepping gait. ► The largest Lyapunov exponent during lateral stepping and typical forward walking was compared. ► Similar variability in the primary and secondary planes of progression for lateral stepping and forward walking....

Zusammenfassung:Highlights ► We investigated the structure of variability for a lateral stepping gait. ► The largest Lyapunov exponent during lateral stepping and typical forward walking was compared. ► Similar variability in the primary and secondary planes of progression for lateral stepping and forward walking. ► Increased active control in the secondary plane of progression during gait. ► Findings support potential use of lateral stepping training to improve overall walking.
