High-frequency electrical stimulation blocks spasticity to help paraplegics walk again

Electrical stimulation of the spinal cord is a promising strategy for reestablishing walking after spinal cord injury, recent studies show. But for patients suffering from muscle spasms, the stimulation protocols have a limited effect due to the unpredictable behavior of involuntary muscle stiffness related to spasticity. Muscle spasticity affects almost 70% of spinal cord injured patients.
