The long-term goal of our research is to maximize upper limb recovery after stroke using neural stimulation and motor activity to drive plasticity.  We use transcranial magnetic stimulation to examine the neural basis of upper limb muscle coactivation patterns and changes in connectivity after neural injury.  We are also developing non-invasive and painless methods to increase excitability of the cervicothoracic spine using magnetic stimulation.
