RESUMO
A previous study by our group showed preliminary results showcasing the usage of optimal and individualized spinal cord transcutaneous stimulation (scTS) parameters during overground gait training to facilitate more repeatable gait kinematics profiles for one participant with an incomplete spinal cord injury (SCI). The goal of this study was to use the combined targeted scTS and training to improve spatial and temporal parameters to achieve a symmetrical gait profile after completing activity-based training (ABT) (stepping and stand training) and exoskeleton training with and without scTS. Our data indicates that stimulation with optimal and individualized parameters can lead to more effective, stable and symmetric gait patterns in participants with varied levels of SCI.Clinical Relevance- This analysis will enable us to better understand the combined effect of exercise based training and tonic scTS on improving the quality and symmetry of gait pattern in participants with incomplete SCI.

Spinal cord transcutaneous stimulation (scTS) has shown its potential for boosting motor, sensory, and autonomic function recovery after a spinal cord injury. Despite the demonstrated benefits, little is known about the exact neuromodulatory mechanisms triggered by scTS and the cortex involvement in the beneficial effects observed. Here, we examine the effects of scTS-based motor training and motor training alone on sensorimotor cortical functional connectivity and corticospinal excitability in able-bodied and SCI participants.Clinical Relevance- The results show preliminary evidence of differential cortical involvement and modulation by scTS-based motor training in uninjured and spinal-cord injured individuals. A better understanding of scTS mechanisms of action could help optimize the intervention design and potentiate its benefits.
