Brain therapy might help stroke rehab

Stroke is the leading cause of permanent disability in the United States. So many people need physical, occupational and speech therapy to recover. I recently read about research that might lead to better tools to help stroke patients to recover.

This article describes how brain therapy helps rehabilitate stroke patients:
A new interventional therapy that uses a brain–computer interface appears to change brain activity in patients with stroke, new research has shown.
The therapy alters specific areas of the brain that correlate with both the affected and unaffected hands. The activation of these areas of the brain appears to correspond to executed and imagined tasks of the affected hand, and may represent neuroplastic recovery.
"Brain activity fed back to the patient is key for the therapy," explained Vivek Prabhakaran, MD, director of functional neuroimaging in radiology at the University of Wisconsin in Madison.
