Locomotor adaptation to visual cueing of impending mechanical perturbations during treadmill walking
Purpose: To determine whether visual cueing of the magnitudes of impending mechanical perturbations facilitates adaptation during perturbed walking.
Hypothesis: Visual cueing of impending mechanical perturbations will facilitate adaptation (specifically, result in larger margins of stability compared to no cueing).
Brief decelerate belt speeds during every right midstance can perturb walking and balance .
Subjects initially decreased anterior-posterior margin of stability when first experiencing the perturbations but adapted back towards baseline .
Visual cueing of the perturbations may facilitate an anticipatory strategy and increase adaptation .
