MEP Up-conditioning to Target Corticospinal Plasticity

Individuals with chronic cervical spinal cord injury will complete a 10-week training protocol where participants receive non-invasive brain stimulation and feedback on the size of the corresponding muscle response (wrist extensor).

Investigators will assess the impact of the brain stimulation training on 1) the brain-to-spinal cord-to-muscle connection and 2) motor functions of the arm and hand. Also, brain and spine magnetic resonance imaging will be collected before and after the training. The imaging measurements will tell investigators about how spinal damage, brain function, and brain structure relate to motor presentation and the response to the training.
