Pulses of electricity delivered to a precise location on the spinal cord have helped two stroke patients regain control of a disabled arm and hand, a team reports in the journal Nature Medicine.
The success should give "a lot of hope" to hundreds of thousands of people in the U.S. who've been disabled by a stroke, says Dr. Walter Koroshetz, director of the National Institute of Neurological Disorders and Stroke, which helped fund the research.
