Neural Changes in Stroke Patients During Challenging Walking Tasks.

For stroke patients, a challenging, unfamiliar, and more difficult task may increase the likelihood of brain activation to stimulate recovery. Pedal walking and walking with eyes-covered are both difficult and challenging tasks for stroke patients. The investigators intend to study the biomechanics and neural mechanisms of challenging pedal walking and walking with eyes covered. Stroke participants will wear electroencephalogram electrode caps and perform three tasks: walking on a flat surface for 60 seconds, walking on pedal for 60 seconds, and walking with eyes covered for 60 seconds.
