Neuromodulation of Spinal Locomotor Circuitry to Elicit Stepping After Pediatric Spinal Cord Injury

About this trial

This is a trial to test the effect of a technique for stimulating the spinal cord via surface stimulation (i.e., transcutaneous spinal stimulation: TcStim) on stepping in children with spinal cord injury. The study consists of 3 independent parts. If included, the participant will receive one of: 1) TcStim at single or multiple spinal levels while lying down to produce muscle activity in lower limbs; 2) TcStim while stepping on a moving treadmill with a supportive harness that holds the participant upright i.e. Body-weight support (BWS) + TcStim; 3) 60 x 1-hour BWS training sessions, 5 times per week, followed by combination training of BWS + TcStim for another 60 x 1-hour sessions, 5 times per week. Combination training activities include standing, stepping, and sitting on and off the treadmill.
