WASHINGTON, D.C. — Three people with a muscle-destroying disease destined to worsen got a little stronger — able to stand and walk more easily — when an implanted device zapped their spinal cord.
On Wednesday, researchers reported what they called the first evidence that a spine-stimulating implant already being tested for paralysis might also aid neurodegenerative diseases like spinal muscle atrophy — by restoring some muscle function, at least temporarily.
