Transfer of reactive balance adaptation from stance-slip perturbation to stance-trip perturbation in chronic stroke survivors.

CONCLUSIONS: Chronic stroke survivors demonstrated improved direction-specific compensatory stepping response on a novel trip-perturbation following reactive adaptation to large-magnitude, stance-slip perturbation training.New and Noteworthy:The present study investigates the ability of chronic stroke survivors to generalize motor adaptation from stance-slip perturbation training to a novel, diametrically opposing trip-perturbation. We report that the people with chronic hemi-paretic stroke could employ the acquired adaptation in reactive postural stability in order to improve reactive stepping responses to a novel stance-trip perturbation via generation of a direction-specific effective compensatory stepping response, such that the training group demonstrated a longer forward compensatory step and better control of postural stability than the control group.
