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

"Transcutaneous spinal stimulation (TcStim): The 5-channel stimulator capable of generating (41) pain-free biphasic rectangular waveform of 0.3- to 1.0-ms pulses with a frequency of 5-10 kHz will be used to stimulate at single or multi-site spinal levels.~TcStim will be delivered in combination with activity based locomotor training in 5 - 10 minute of stimulation at sub-motor threshold daily (5x/week) for 60 sessions"

Participants will receive a combination of Activity-based locomotor training (AB-LT)+TcStim daily (5x/week) for 60 sessions and will consist of a minimum of 55-60 min on the TM for facilitated standing/stepping followed by 30 min of activities off TM in sitting, standing, or stepping.
