Augmenting normal motor function and reducing abnormal motor output (spasticity) after spinal cord injury has long been a goal in rehabilitation, either in the form of neural prosthetics (replacing function) or as augmented therapy (to somehow enhance neural plasticity and recovery of function). While direct muscle stimulation (FES) has been explored, newer research has aimed at substituting for lost supraspinal input with artificial sensory augmentation to better activate spinal neural networks for stepping. These approaches have included stimulation of peripheral nerves or spinal cord stimulation. This course will review the state of the art with different stimulation methodologies, combining stimulation with rehabilitation training, how altering stimulation parameters can impact the outputs of spinal neural circuits, and how neuromodulation can be optimized in real time at different stimulation sites specifically for different patients.
