Possible benefits of brain stimulation on hand, arm movement following stroke

Researchers are studying whether stimulating the brain before rehabilitation could yield greater gains in motor function for people recovering from stroke. The technology is akin to a more advanced version of constraint-induced therapy in which clinicians physically tie down a patient's good arm, which forces the patient to use the injured side. With this non-invasive device, researchers are using electromagnetism to slow activity in portions of the healthy brain hemisphere that control the uninjured arm, similarly forcing the brain to use its injured half.
