Stroke Rehabilitation Using BCI Technology

The aim of this study is to determine if functional muscle stimulation, in addition to
non-invasive neurostimulation, directed by EEG output, can increase the extent of stroke
recovery on behavioral measures and induce brain plasticity as measured by functional
magnetic resonance imaging. Our ongoing research suggests that noninvasive EEG driven Brain
Computer Interface (BCI) systems hold the potential for facilitating recovery in the chronic
phase after stroke by synchronizing central or brain activity with peripheral movements and
thereby harnessing brain plasticity.

Inclusion Criteria:

- New-onset ischemic stroke 12 months prior - chronic time frame;

- Right hand dominant - affected arm;

- Mild to moderate unilateral upper extremity impairment or severe unilateral upper
extremity impairment;

- No upper extremity injury or conditions that limited use prior to the stroke;

- Must be able to provide informed consent on their own behalf.

Exclusion Criteria:

- Contraindications to MRI

- Allergies to electrode gel, surgical tape, or metals

- Pregnancy

- Current treatment for infectious disease

- Active oral lesions or inflammation.
