Walking via brain stimulation

'It depends how much signal was getting through in the first place.'

- 

Electrically stimulating a particular region in the brain could help people with injured spinal cords walk more easily, scientists said this week, with one patient describing how the technique allowed him to conquer his fear of stairs.

The new technique is intended for people with spinal cord injuries where the connection between their brain and spinal cord has not been totally severed, and who still have some movement in their legs.

Wolfgang Jaeger, one of two patients who took part in an early trial, said it immediately made a "big difference" to his mobility.

"Now when I see a staircase with just a few steps, I know I can handle it on my own," the 54-year-old said in a video released alongside a new study in the journal Nature Medicine.

The research was conducted by a Swiss team that has pioneered several recent advances, including using electrical stimulation of the spinal cord to let several paralyzed patients walk again.

This time around, the researchers wanted to figure out which region of the brain was most responsible for people recovering from spinal cord injuries.
