For those following SCI research in the electrical stimulation field, this open access article in Nature Communications is worth a read.  Here, the Gregoire Courtine lab describes the concept and project where brain-controlled modulation coupled with constant stimulation during gait rehabilitation would enhance locomotion.   They were able to show that brain-controlled stimulation enhances voluntary overground walking and even staircase climbing!  The closed circuit loop increased and improved recovery compared with continuous stimulation only being delivered to the spinal cord during gait rehabilitation.    (cp)
