A study published in the medical journal Nature on Monday found that targeted electrical pulses delivered to the spinal cord can help improve arm and hand movement after a stroke. Two patients were able to regain additional motion in their arm and hand through a device implanted at the base of the spine, which delivered pulses in areas responsible for hand and arm function.

A fist that opened and shut. A once-limp arm that moved from her side. Two women whose strokes left them with partial paralysis for years saw life trickle back to their limbs when electric pulses were delivered to the back of their spinal cord as part of a pilot study. Neurologists said the approach, reported Monday in the journal Nature Medicine, could be transformative for stroke survivors, many of whom have some arm impairment after the event.

“They’re not just getting flickers of movement. They’re getting something important,” said Dr. Jason Carmel, a Columbia University neurologist who wasn’t involved with the new experiment but also studies ways to recover upper-limb function. “It’s a very exciting proof of concept.” (Neergaard, 2/20)
