For people who’ve had a stroke, a treatment that involves applying an electric current to the brain may help boost recovery of their mobility, a small clinical trial found.
Stroke is the most common cause of severe, long-term disability. Rehabilitation training, which helps patients re-learn how to use their bodies, can help some patients recover their ability to move. But it is often costly and time-consuming.
The new study looked at 24 patients; each had experienced a stroke that affected his or her ability move a hand and arm. Half of the participants were picked, at random, to receive nine days of rehab paired with a brain-stimulation technique known as transcranial direct current stimulation (tDCS). This method uses electrodes placed on the scalp to deliver constant, low electrical currents to specific areas of the brain. The other patients received a sham control treatment; they were fitted with electrodes but did not receive tDCS. Continue reading “Brain Stimulation Could Speed Stroke Recovery”
