This project will evaluate two different methods of normalizing the center of mass acceleration (COMa) in individuals post-stroke, specifically focusing on rates and pattern of recovery to analyze walking-specific adaptations as precursors to motor learning. In addition, the proposed project seeks to establish the optimal configuration of electrodes to activate neural circuits involved in post-stroke locomotion. Once the better method of training COMa and optimal parameters of electrode placement for tDCS are identified, the investigators will evaluate the effects of tDCS on locomotor adaptations during single sessions and over a five-day training period.
