Abstrakt:	We examined the possibility of initiation of involuntary stepping movements by spinal electromagnetic stimulation (SEMS) during leg suspension. The subject's legs were supported by a special apparatus in a gravity neutral position that to provide horizontal rotation in the hip, knee and ankle. SEMS (3 Hz and 1.56 Tesla) over the T11-T12 vertebrae induced involuntary locomotor_like movements in the legs. The latency period from the initiation of stimulation to the first EMG burst was 0.68 1.0 s. Increasing the frequency of SEMS from 3 Hz to 20 Hz resulted in shortening of the latency period. Thus, SEMS is able to initiate involuntary stepping in humans. [ABSTRACT FROM AUTHOR]
