“…For instance, if healthy individuals usually generate requisite momenta within speci c gait phase contexts during turns, we can provide gait-phase speci c balance rehabilitation targets for resistance/perturbation protocols speci c to each gait phase. [18][19][20] Prior research provides initial indications that motor control patterns during turning maneuvers may mimic those in straight-line gait. In recent computational research, Desmet, Cusumano, and Dingwell demonstrated that humans control foot placement during side-stepping (a maneuver used during turns) by modulating stepping regulation strategies used during straight-line gait, rather than switching to use a distinctly different control strategy.…”

Turning while walking is ubiquitous and requires generation of linear and angular momenta to redirect the Center of Mass (COM) trajectory and rotate the body towards the new direction of travel. The purpose of this study was to examine strategies that healthy young adults used during each gait phase to generate transverse-plane momenta during pre-planned and late-cued 90° turns. During leftward turns, we expected that momenta would be generated most during the gait phases known to generate leftward COM velocity and leftward body rotations during straight line gait. We found distinct roles of gait phases towards generating momenta during pre-planned and late-cued turns, supporting our hypotheses. Specifically, during right foot single support (when only the right foot is in contact with the ground), the changes in leftward linear momentum and average leftward acceleration were greatest. During double support (both feet contacting the ground) with the left foot in front, the changes in transverse-plane angular momentum and average moment were greatest. These findings align with the prior understanding of momenta regulation during straight-line gait, suggesting that healthy young adults can leverage momenta control strategies used during straight-line gait to generate transverse-plane momenta required by turns.

Turning while walking is ubiquitous and requires linear and angular momenta generation to redirect the body’s trajectory and rotate towards the new direction of travel. This study examined strategies that healthy young adults used during each gait phase to generate transverse-plane momenta during pre-planned and late-cued 90° turns. During leftward turns, we expected that momenta would be generated most during the gait phases known to generate leftward linear and angular momenta during straight line gait. We found distinct roles of gait phases towards generating momenta during turns that partially supported our hypotheses. Supporting one hypothesis, the change in transverse-plane angular momentum and average moment were greater during double support with the left foot in front vs. other gait phases. Also, the change in leftward linear momentum and average leftward force were greater during right single support vs. other gait phases during straight-line gait and late-cued turns. However, during pre-planned turns, the average leftward force was not significantly greater during right single support vs. other gait phases. Overall, transverse-plane angular momentum generation during turns is similar to its generation during straight-line gait, suggesting that healthy young adults can leverage momenta control strategies used during straight-line gait during turns.
