Partial nerve conduction block using a separated interface nerve electrode (sine)

A system comprising:

• a waveform generator configured to generate one or more direct current (DC) waveforms, wherein the one or more DC waveforms each comprise at least one parameter and are configured to provide a partial block to a neural structure for a time period;
• one or more electrodes configured to deliver the one or more DC waveforms to the neural structure to provide the partial block of the neural structure for the time period;
• and
• a feedback device configured to monitor a property of the partial block of the neural structure and provide feedback to the waveform generator to alter the at least one parameter of the one or more DC waveforms based on the property of the partial block of the neural structure to maintain the partial block at a stable block level during the time period.
