Figure 1.
Position, size, and number of transspinal cathode electrodes for KNIKOU-LAB4Recovery protocol (P-KLAB), protocol 2 (P-2), protocol 3 (P-3), and protocol 4 (P-4). For all 4 protocols the top edge of the electrode corresponded to Thoracic 10 (T10) vertebrae level. The space between the electrodes in P-3 and P-4 was 1 cm, while they were connected to act as 1 electrode in a manner similar to the anodes placed bilateral on the iliac crests. Body position is shown for representation purposes, as transspinal stimulation was delivered with subjects’ supine and both hips and knees flexed at 30°.
