Previously, we reported that transcutaneous electrical stimulation of the spinal cord at vertebral level T11 can activate the locomotor circuitry in noninjured subjects when their legs are placed in a gravity-neutral position (Gorodnichev RM, Pivovarova EA, Pukhov A, Moiseev SA, Savokhin AA, Moshonkina TR, Shcherbakova NA, Kilimnik VA, Selionov VA, Kozlovskaia IB, Edgerton VR, Gerasimenko IU. Fiziol Cheloveka 38: 46\u201356, 2012). In the present study we hypothesized that stimulating multiple spinal sites and therefore unique combinations of networks converging on postural and locomotor lumbosacral networks would be more effective in inducing more robust locomotor behavior and more selective control than stimulation of more restricted networks. We demonstrate that simultaneous stimulation at the cervical, thoracic, and lumbar levels induced coordinated stepping movements with a greater range of motion at multiple joints in five of six noninjured subjects. We show that the addition of stimulation at L1 and\/or at C5 to stimulation at T11 immediately resulted in enhancing the kinematics and interlimb coordination as well as the EMG patterns in proximal and distal leg muscles. Sequential cessation of stimulation at C5 and then at L1 resulted in a progressive degradation of the stepping pattern. The synergistic and interactive effects of transcutaneous stimulation suggest a multisegmental convergence of descending and ascending, and most likely propriospinal, influences on the spinal neuronal circuitries associated with locomotor activity. The potential impact of using multisite spinal cord stimulation as a strategy to neuromodulate the spinal circuitry has significant implications in furthering our understanding of the mechanisms controlling posture and locomotion and for regaining significant sensorimotor function even after a severe spinal cord injury. <\/jats:p>","DOI":"10.1152\/jn.00609.2014","type":"journal-article","created":{"date-parts":[[2014,11,7]],"date-time":"2014-11-07T08:41:32Z","timestamp":1415349692000},"page":"834-842","source":"Crossref","is-referenced-by-count":154,"title":["Initiation and modulation of locomotor circuitry output with multisite transcutaneous electrical stimulation of the spinal cord in noninjured humans"],"prefix":"10.1152","volume":"113","author":[{"given":"Yury","family":"Gerasimenko","sequence":"first","affiliation":[{"name":"Pavlov Institute of Physiology, St. Petersburg, Russia;"},{"name":"Integrative Biology and Physiology, University of California, Los Angeles, California; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruslan","family":"Gorodnichev","sequence":"additional","affiliation":[{"name":"Velikie Luky State Academy of Physical Education and Sport, Velikie Luky, Russia;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aleksandr","family":"Puhov","sequence":"additional","affiliation":[{"name":"Velikie Luky State Academy of Physical Education and Sport, Velikie Luky, Russia;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tatiana","family":"Moshonkina","sequence":"additional","affiliation":[{"name":"Pavlov Institute of Physiology, St. Petersburg, Russia;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aleksandr","family":"Savochin","sequence":"additional","affiliation":[{"name":"Pavlov Institute of Physiology, St. Petersburg, Russia;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Victor","family":"Selionov","sequence":"additional","affiliation":[{"name":"Institute for Information Transmission Problems, Russian Academy of Science, Moscow, Russia;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roland R.","family":"Roy","sequence":"additional","affiliation":[{"name":"Integrative Biology and Physiology, University of California, Los Angeles, California; and"},{"name":"Brain Research Institute, University of California, Los Angeles, California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel C.","family":"Lu","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery University of California, Los Angeles, California;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"V.
