Locomotion Adaptation Deficits in Older Adults With Mild Cognitive Impairment and Alzheimers Disease

Participants will complete 5 sessions of split-belt treadmill-based locomotor adaptation. The split-belt instrumented treadmill allows the two belt speeds to be operated independently, enabling different belt speeds for each leg. The split-belt walking assessment will consist of 3 phases: baseline phase in which the belts operated at the same speed (Pre-tied, 2-minutes), a phase in which the belts operated at different speeds (Split-belt, 15-minutes), and a final phase in which the belts operated at the same speed (Post-tied, 4-minutes).
