Dr. Richard Stein of the University of Alberta and his colleagues have been working on an electronic device designed to be placed directly on the spinal cord to assist with walking in SCI survivors. Devices such as this have been around for some time now, but Dr. Stein’s ambition is to create one that records sensory feedback coming from the muscles and nerves in the legs and hips. Basically, it’s a closed loop system: legs communicate back and forth with the computer. Think of it as an extra “brain” designed specifically to control the lower limbs.
